Abstract

The present invention relates to a syringe-replaceable automatic medicator. More specifically, injection can be easily performed when an unskilled diabetic patient performs injection himself/herself or when injection is performed on a child showing a lot of movements. In particular, according to the present invention, injection power of an injection liquid is maintained, and an injection speed thereof may be mildly adjusted, so shock or excessive injection does not occur in a patient′s body when the injection liquid is injected. Moreover, a general disposable syringe may be replaced and used, so burden of costs spent in using syringes may be minimized. The size thereof is small, so the syringe-replaceable automatic medicator may be very conveniently used and stored. The structure and operational procedure thereof are simple, so the syringe-replaceable automatic medicator may be semi-permanently used. Accordingly, reliability and competitiveness may be improved not only in the syringe and medication fields but also in the similar or related fields. The syringe-replaceable automatic medicator comprises: a housing (100); a piston (200) formed to have a grip (210) exposed to the outside of the housing (100); and an elastic unit (300) for downwardly pressing the piston (200), so the piston (200) presses a plunger (P) of a syringe (S).

Description

[0001] The present invention relates to a syringe interchange type automatic medication,

The present invention relates to a syringe replaceable automatic dispenser, and more particularly, to an automatic dispenser for syringe replacement, and more particularly, to an automatic dispenser capable of easily injecting a dispenser, such as a diabetic patient, .

Particularly, the present invention enables semi-permanent use by replacing the disposable syringe, thereby making it possible to control the infusion rate while maintaining the main input of the infusion liquid. Thus, So that excessive injection does not occur.

In general, a syringe is a medical instrument used for collecting blood or injecting a chemical liquid directly to a patient. The syringe is a barrel containing a drug solution, a blood collection device for introducing a blood sample into the barrel, A plunger for injecting the drug into the patient, a flange formed on the barrel to support the drug solution when the drug solution is injected, and the like.

Such a syringe is used mainly by a doctor or a nurse such as a doctor in a hospital, but in some cases, a non-specialist, such as a doctor or a nurse, may need to inject the patient (or himself). For example, in the case of diabetic patients, the patient himself or the patient's family often injects the drug solution in a place other than a hospital.

However, it is difficult for a non-specialist including the patient himself to inject himself / herself (or other patient). For example, in the case of direct injection into itself, since the syringe can move in the process of pressing the plunger, there is a problem that the injection needle moves in the skin to cause pain or the injection liquid can not be injected smoothly.

Particularly, in the case of a patient having fear of needles, there is a problem that the patient can not inject himself or herself in the case where the patient has an elderly person or a problem of diversion.

In addition, depending on the patient, even a specialist may experience difficulty in injection. For example, if you are injecting a child with severe motion, you may have difficulties even if you are a professional.

In order to solve this problem, automatic syringes such as the prior art have been developed.

(Hereinafter referred to as " Prior Art 1 ") and Korean Patent Laid-Open Publication No. 10-2014-0024760 (hereinafter referred to as " Automatic Syringe Device ", Korean Patent Registration No. 10-0977283) (Hereinafter, referred to as "Prior Art 2") is a technique relating to a syringe to allow a patient to easily inject himself / herself.

However, since the syringe is used for disposable use due to hygiene problems, the syringe having a complicated structure such as the prior art has a considerable manufacturing cost, and therefore, it is very burdensome to use it as disposable.

As a result, prior art techniques may be convenient for non-specialists, but they are very limited when used in practice, since they cause an increase in the cost of disposable syringes, and even if used, .

An example of a syringe replaceable automatic medicine dispenser according to the present invention can be variously applied, and a most preferred embodiment will be described below with reference to the accompanying drawings.

1 is an exploded perspective view showing an embodiment of a syringe replaceable automatic medicine dispenser according to the present invention,

Referring to FIG. 1, a syringe replaceable automatic medicine dispenser A includes a housing 100, a piston 200, and an elastic ball 300.

The housing 100 has a hollow portion 110 formed therein and an opening 120 is formed at a lower portion of the hollow portion 110 to allow a syringe S to be replaceable. For example, the housing 100 may be composed of a hollow cylindrical tube as shown in Fig.

The housing 100 may further include a coupling hole 130 in which a flange F of the syringe S is detachably coupled to at least one side of the opening 120.

The piston 200 may be supported to maintain the position at the upper side of the hollow portion 110 or may be slid in the vertical direction at the hollow portion 110 so that the handle 210 for sliding movement of the user may be configured .

In other words, the piston 200 can be moved up and down in the hollow portion 110 of the housing 100, and can be supported so that its position is maintained at a predetermined upper position by a user's operation.

The elastic ball 300 is configured to be inserted into the hollow portion 110 and presses the piston 200 downward so that the piston 200 presses the plunger P of the syringe S. For example, the elastic ball 300 may be configured to fit between the upper surface of the hollow portion 110 and the piston 200. 1, the elastic bulb 300 may be formed of a spring, but not limited thereto. The elastic bulb 300 may be a spring (not shown) such as a small-sized sound pressure expanding device (module) 200 can be pressed down or moved in the upper and lower directions.

Fig. 2 is a perspective view for explaining the housing shown in Fig. 1 in detail.

Referring to FIG. 2, a guide slit 140 may be formed on at least one side of the housing 100 in a vertical direction.

1, the handle 210 of the piston 200 may penetrate through the guide slit 140 shown in FIG. 2, and the handle 210 may be inserted into the guide groove 210 of the piston 200, And can be exposed to the outside of the housing 100.

The handle 210 of the piston 200 is slid in the vertical direction along the guide slit 140 of the housing 100 and can be supported at the upper portion of the guide slit 140. [

The support hole 141 is extended to be bent at the upper end of the guide slit 140 as shown in FIG. 2 so that the handle 210 of the piston 200 is supported at the upper portion of the guide slit 140 .

When the user moves the handle 210 of the piston 200 to the upper portion of the guide slit 140 and then moves to the support hole 141, the handle 210 is supported by the support hole 141, The second housing 200 can maintain a predetermined position.

As another example, in the state that the button 200 is provided on the upper side of the housing 100 and the piston 200 is supported to be caught by the latch, when the user presses the button, the piston 200 is released from the latch, As shown in FIG.

The coupling hole 130 of the housing 100 is opened to the lower side so that the flange F of the syringe S is inserted into the insertion hole 130 of the automatic medicine dispenser A, And a fitting hole 132 into which a flange F of the syringe S is inserted can be formed.

At this time, the fitting hole 132 may be formed to extend horizontally in the insertion hole 131 as shown in FIG.

Meanwhile, the elastic ball 300 shown in FIG. 1 must be configured to have a sufficient elastic force to smoothly scan the injection liquid in the disposable syringe S, which will be described later, and such elasticity may adversely affect the patient's body .

In other words, an elastic ball (spring) having a considerable force (elastic force) is required to inject a highly viscous liquid medicament into a patient through a relatively thin needle, but in this case, .

Therefore, it is necessary to apply a large force for smooth injection of the chemical liquid, but to slow the rate.

Hereinafter, a method of preventing the syringe S or the patient's body from being impacted by such an elastic force in a state in which sufficient elasticity is provided so as to smoothly inject the injection liquid will be described.

3 is a perspective view for explaining the piston shown in Fig. 1 in detail.

Referring to FIG. 3, a damper pad 220 may be formed on the lower surface of the piston 200.

3, when the piston 200 descends due to the elastic force of the elastic ball 300, the damper pad 220 is brought into close contact with the plunger P of the syringe S, And may be in close contact with the inner surface of the hollow portion 110.

When the side surface portion of the damper pad 220 is in close contact with the hollow portion 110 of the housing 100 as described above, frictional force is generated when the piston 200 is lowered. Thus, the piston 200 is prevented from falling down excessively fast can do.

In addition, even when the piston 200 descends and is brought into close contact with the plunger P of the syringe S, the impact force due to the elastic force of the elastic ball 300 can be attenuated.

4 to 6 are views for explaining a method of using the disposable syringe using the automatic medicament of FIG.

The handle 210 of the piston 200 of the automatic medicine dispenser A may be moved upward so as to be supported by the support hole 141 of the guide slit 141.

The plunger P of the syringe S is inserted into the hollow portion 110 through the opening portion 120 of the automatic medicine dispenser A in a state in which the handle 210 is supported in the support hole 141, As shown in Fig.

5, the flange F of the syringe S is inserted into the insertion hole 131 of the coupling hole 130, and then the syringe S is inserted into the insertion hole 131 of the coupling hole 130 as shown in the right side of FIG. So that the flange F can be fitted into the fitting hole 132.

The section (a-a line section) in the fitted state is as shown in the left side of Fig.

6, when the medicine is filled in the barrel B of the syringe S, the plunger P of the syringe S contacts the automatic medicine dispenser A, (D).

6, when the handle 210 ('b' portion) fitted to the support hole 141 is moved to the guide slit 140 as shown in the left side of FIG. 6 for the user to perform scanning, the elastic force of the elastic ball 300 The piston 200 can push the plunger P to inject the chemical liquid.

Once the injection is completed, the user may pull the handle 210 to move into the support hole 141 and then disconnect the disposable syringe S from the automatic dispenser A in the reverse order of FIGS. 4 and 5, (A) can be used semi-permanently by replacing another disposable syringe (S).
