Description

Automatic syringe

The new apparatus of this practicality is about the utility model product in the technical field of medical instruments.

The major technique of this apparatus is characterized as an aid of finishing inserting needle and liquid medicine injection continuous process automatically, and the mechanical force that produces with the compression spring replaces the active force of staff muscle and finishes said process.Through retrieval, consult and understand existing medical device technology data, can illustrate that this apparatus has novelty, creativeness and practicality.

Order of the present invention and be: a, the natural sequence that produces with apparatus replace the non-sequence by people's hand control; B, simplify procedures, make the personnel that were not subjected to professional training comprise that patient self also can independently finish injection process easily; The randomness that c, solution inserting needle of the prior art and injection speed vary with each individual can be by arbitrarily being adjusted by injection people's wish by adjusting device; D, solution overcome the relatively poor shortcoming of injection site accuracy that existing injection technique causes because of rocking of staff, take to aim in advance injection point, and the mode of the inserting needle of bursting improves the inserting needle degree of accuracy; E, replace traditional method of clamping, easilier grasp the injection main points for the ordinary people syringe with pistol handle gripping mode; By health, convenience, complete perfect medical apparatus and instruments design principle, former injection product are become be separated into concentratedly, the device articles for use assembly of formation containerization makes the user more feel facility.

This filling gun is that to be engaged in the compression spring that is provided with in the rifle be thereby that power makes the quick translation inserting needle of syringe body thrust skin, and then continues to promote the piston motion in the syringe, and medicinal liquid is injected the automatic medical apparatus that muscle is finished a continuous action.Its operation principle and work process are described as follows stage by stage: 1, at first open the movable Cang Gai on the body of a gun.The syringe of filling with medicinal liquid is put into the storehouse, and shift stack shell onto firing position, at this moment whole syringe all is positioned at the rifle storehouse together with the syringe needle position, and be in static arm-to-arm, cover removable cover, regulating the afterbody spiral is on proper compression state (how little according to syringe length and liquid medicine injection, and the selected injection speed is determined) accompanying drawing inner compression spring to have indicated each parts and the relative position under this state.

Disinfectant injection point is aimed at and propped up to muzzle, kowtow the plate machine, under the effect of compression spring, syringe pushes away frame by pressure and is subjected to impacting and moves to muzzle rapidly, the obstruction that is subjected to the muzzle buffer gasket owing to syringe body front end at the muzzle place stops translational motion, and needle point thrusts muscle fast when said process carries out.At this moment the elongation △ xI of spring accounts for 2/5 of total elongation, and the inserting needle action finishes.

Spring continues elongation, pushes away the translation of frame promotion syringe inner carrier by pressure and finishes the action of liquid medicine injection till the inner carrier propelling puts in place; At this moment the elongation △ x2 that compresses spring accounts for 4/5 of total elongation, because spring does not recover former length fully, so pressure pushes away frame piston base is still kept certain pressure thrust, injects muscle to guarantee that medicinal liquid does not all have surplusly.This process finishes, and the action of liquid medicine injection finishes.

After injection finishes,, transfer to muscle together, finish withdraw of the needle action by the buffer gasket drive syringe and the syringe needle of muzzle with the translation backward of the whole body of a gun.

Open Cang Gai and take out stack shell, syringe syringe needle and other injection articles for use such as absorbent cotton, disinfectant, tweezers etc. are put into the disinfection box that pikestaff is provided with, build the pikestaff lid and finish whole injection work.

This utility model apparatus is compared with existing traditional syringe and injection system tangible advantage and positive effect.Its major advantage and good effect now mainly go on to say from using except that part has been illustrated in the goal of the invention statement:

Except that medical department uses, more can on animal and veterinary, promote the use of, be an apparatus that widely-used prospect is arranged, inject time is short, high efficiency.Reduce mistake, avoid malpractice.More meet hygienic practice:, the compound mode of one rifle, one pin, one box and the assembling of the integral body of containerization can alleviate the degree of environmental pollution syringe, and whole needle body all is not contained in the sterile rifle storehouse and is in the relative isolated requirement that meets health more with external environment when particularly not injecting.

The continuity of inserting needle and injection process action is better than traditional noncontinuity injection system well, the patient is willing to use, to alleviating patient's misery, the elimination patient has positive auxiliary curative effect to the feared state of mind of the pointed one-tenth of minute hand, particularly child has curious sense, easier and medical worker's partner treatment to pistol.

Because this instrumentation is very easy, very likely making it walk out Medical Treatment Room becomes everybody and can use every household indispensability, the urgent rescue utensil that out of town trip is carried.

Have the profile and the function of toy concurrently, when not placing syringe, can make general toy and use.

Description of drawings: relative position and number order explanation (1) rubber buffer circle of pressing parts on the accompanying drawing; (2) plastics gun barrel; (3) syringe cylinder; (4) plastics positioning support circle; (5) syringe inner carrier; (6) pressure pushes away frame; (7) plate machine; (8) pikestaff; (9) aluminum disinfection box folder; (10) compression spring; (11) pressure adjustable screw; (12) body of a gun; (13) open-type activity Cang Gai; (14) syringe needle.

In the accompanying drawing illustrated embodiment, rubber buffer circle (1) is connected in muzzle with plastics gun barrel (2) with bonding mode, plastics positioning support circle (4) is connected in middle part in the gun barrel with bonding mode and plastics gun barrel (2), pressure pushes away groove pawl minute hand tube inner carrier (5) bottom that frame (6) has above, be subjected to the machinery control of plate machine (7) during its percussion state, compression spring (10) one ends push away frame (6) with pressure and contact, the other end contacts with the interior tube bottom of pressure adjustable screw (11), and place the body of a gun (12) inside, pressure adjustable screw (11) and the body of a gun (12) are to be threaded, and disinfection box folder (9) is connected with bonding mode with pikestaff (8).

The applicant thinks that implementing automatically continuously the apparatus of injection system can also adopt alternate manner except that the present invention: thus as with pneumatic, surge, electromagnetism is that the compression spring that power replaces this device is finished automatic successive injection process; Also available fixed bearing support or around the activity of injection site, half movable, pistol type rip into device that fixture replaces the design, or the design's disinfection box is provided with the position, also can take remote control unit to replace the design's plate machine percussion lock, also available gun barrel replaces syringe directly to act on the suction medicinal liquid, the holding frame of pikestaff also can directly be installed, or syringe and pistol handle form one by mechanical connections such as certain bonding screws on syringe.The applicant thinks that this filling gun is to realize automatically the best way of injection continuously at present.
