Definitions
- the present disclosure relates to a chemical solution pumping module and a method for preparing a drug solution injection using the same.
- a drug solution injection device for injecting a liquid drug solution (eg, an injection solution) into a patient.
- a liquid drug solution eg, an injection solution
- the drug solution in a predetermined storage space passes through a passage connected to the patient (for example, an inner space of a tube and an injection needle) and is introduced into the patient's body.
- a conventional chemical injection device injects a chemical solution through a process of expansion and contraction. Specifically, when the chemical solution is filled into the inside of the chemical solution injection device, the space filled with the chemical solution expands and a pressure is generated to contract the space filled with the chemical solution, and the chemical solution is injected using energy to return the space to its original volume.
- a drug solution within the device may be injected into the patient.
- a drug injection device is known that generates pressure for contraction of the stomach by using an elastic body such as a spring type, a balloon type, or an air compression type or compressive energy of air.
- a lubricant for sliding the plunger may be applied to the inner surface of the chamber of the liquid injection device.
- E-WHA Biomedics Co., Ltd. a Korean company, has previously sold a product called "ANAPA", a drug injection device, and at least some embodiments of the present disclosure are upgrades of the existing "ANAPA” device. We present a more innovative device of the version.
- a plunger slides along an inner surface of the chamber, and the inner space is expanded at the same time.
- the lubricant applied to the inner surface may be damaged or entangled and deformed.
- the frictional resistance acting on the plunger is increased.
- the conventional chemical solution injection device has a problem in that a very cumbersome operation is required to perform a priming operation. If a conventional chemical injection device performs a priming operation using a pressurizing operation unit (for example, an air compression type pressurizing unit) that generates a pressurizing force during the liquid injection process, there is a problem in that the pressurization unit must be operated. there is. Embodiments of the method for preparing drug solution injection of the present disclosure solve this problem of the prior art.
- a pressurizing operation unit for example, an air compression type pressurizing unit
- the inner surface of the chamber may adhere to the plunger.
- the adhesion becomes stronger due to the influence of the lubricant, and when the liquid injection device is used, a pressure higher than a predetermined pressure is required to directly move the plunger in the pressing direction for the contraction process. this becomes necessary Accordingly, it may be difficult to start the normal operation of the drug injection device, and a problem may occur in that the set drug injection speed is not maintained during the operation start process.
- Embodiments of the preparation method for liquid injection of the present disclosure solve this problem.
- a chemical liquid pumping module includes a chamber in which an inner space not filled with a chemical liquid and an inlet connected to the inner space are formed; and a plunger disposed inside the chamber so that the internal space has a predetermined volume.
- an inlet connected to the inner space and different from the inlet may be formed in the chamber.
- the chemical solution pumping module may further include a one-way valve disposed at the inlet and configured to allow a flow of the chemical solution moving from the outside to the inner space and block a flow of the chemical solution moving from the inner space to the outside. there is.
- a vent hole may be formed in the chamber.
- the liquid chemical pumping module may further include a hydrophobic filter configured to allow passage of air discharged from the inner space through the vent hole and prevent passage of liquid.
- a chemical solution injection set used in a preparation method for drug injection includes a chamber having an inner space and having different inlets and inlets connected to the inner space; a plunger disposed inside the chamber so that the internal space has a predetermined volume; a pressing operation unit configured to press the plunger so that the volume of the inner space is reduced; and a chemical liquid flow line having a chemical liquid flow passage connected to the inlet.
- a plunger is disposed inside the chamber so that an internal space not filled with the chemical solution has a predetermined volume, so that when the user's chemical solution is filled by the predetermined volume, the plunger moves in the chamber.
- damage to the lubricant film applied to the inner surface of the chamber can be minimized. Accordingly, it is possible to set a constant frictional force applied to the plunger during the above-described contraction process for injecting the drug solution into the patient, and the drug solution can be injected into the patient at a set constant rate of inflow of the drug solution.
- the chemical solution additionally introduced into the internal space (an additional inflow amount of the drug solution) is moved along the connection passage by the pressurization in the priming step even before the operation of the pressurizing operation unit starts.
- priming can be performed quickly and easily.
- the preparation method for injecting the chemical solution when the user fills the internal space with the additional inflow amount of the chemical solution, pressure is generated to push the plunger in the direction in which the plunger should be moved for the priming step without additional manipulation.
- priming can be conveniently performed with minimal actions.
- the plunger When the plunger is moved in the pressing direction for the contraction process immediately from the initial stop state, a pressure higher than the set pressure may be required due to the influence of the above-mentioned adhesion.
- the above-described adhesion may be released by first slightly moving the plunger in a direction opposite to the pressing direction in the additional chemical filling step. Accordingly, when the plunger is pushed in the pressing direction with a predetermined pressure after the additional chemical solution filling step, the above-described adhesion is not affected, so that the normal operation of the chemical solution injection set can be naturally started, and separate additional pressure It is possible to inject the drug solution into the patient at a constant injection rate of the drug solution even without the device.
