CN204233539U - A kind of anti-pollution injector - Google Patents

Abstract

The utility model discloses an anti-pollution syringe, which comprises an outer cylinder and a plunger rod inserted in the outer cylinder. One end of the plunger rod is connected with a sealing plug, and the other end extends out of the outer cylinder, and is fixedly connected with a push-pull handle. The outer cylinder One end is connected to the needle, and the outer edge of the other end of the outer cylinder is provided with a stopper. On the plunger rod, a stop ring is provided on the fixed sleeve near the end of the push-pull handle, and the stop ring and the stopper are sealed and connected. There is an elastic air bag sheathed on the plunger rod, and the elastic air bag is communicated with a buffer bag for reducing pressure through a thin hose. In the anti-pollution syringe provided by the utility model, the plunger rod and the sealing plug do not touch the hand of the operator and the outside air during the dispensing process, which can effectively prevent the cross-contamination of the liquid medicine during the operation of the syringe and ensure the safety of medication.

Description

A kind of anti-pollution syringe

technical field

    The utility model belongs to the technical field of medical devices, in particular to an anti-pollution syringe.

Background technique

 At present, the dosing syringe commonly used in hospitals is an ordinary syringe, which is composed of a syringe, a piston and a push rod. During operation, the medical staff pushes and pulls the piston through the push rod to move, so as to realize operations such as suctioning and mixing the liquid medicine, and dispensing the medicine. The process is: insert the syringe into the liquid medicine bottle to extract a small amount of liquid medicine; then pull out the syringe and insert it into the powder bottle, inject the liquid medicine into the powder bottle, and after the powder and liquid medicine are completely dissolved, draw out the mixed solution and inject it into the infusion inside the bottle. However, in actual use, it is found that when medical personnel perform operations such as suctioning and mixing medicinal liquid, their fingers will touch the push rod, which may cause the medicinal liquid to be contaminated, which will affect the safety of medication.

Utility model content

The purpose of this utility model is to provide an anti-pollution syringe for the deficiencies in the above-mentioned technologies. During the dispensing process of the syringe, the plunger rod and the sealing plug cannot touch the hands of the operator or the outside air, which can effectively prevent the operation The cross-contamination of the liquid medicine during the injection ensures the safety of the medicine.

The technical solution adopted by the utility model to achieve the above purpose is: an anti-pollution syringe, including an outer cylinder and a plunger rod inserted in the outer cylinder, one end of the plunger rod is connected to a sealing plug, and the other end extends out of the outer cylinder, and is fixedly connected with a Push-pull handle, one end of the outer cylinder is connected to the needle, and the outer edge of the other end of the outer cylinder is provided with a stopper. An elastic air bag sleeved on the plunger rod is sealed and connected between the ring and the baffle, and the elastic air bag communicates with a buffer bag for reducing pressure through a thin hose.

The buffer bag and the elastic air bag are detachably connected.

Beneficial effect

In the anti-pollution syringe provided by the utility model, the plunger rod and the sealing plug do not touch the hands of the operator or the outside air during the dispensing process, which can effectively prevent the cross-contamination of the liquid medicine during the operation of the syringe and ensure the safety of the medicine. And the structure is simple, easy to use, suitable for popularization and application.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

An anti-pollution syringe, comprising an outer cylinder 1 and a plunger rod 2 inserted in the outer cylinder 1, one end of the plunger rod 2 is connected to a sealing plug 3, and the other end extends out of the outer cylinder 1, and is fixedly connected with a push-pull handle 4. One end of the outer cylinder 1 is connected to the needle 5, and the outer edge of the other end of the outer cylinder 1 is provided with a stopper 6, which is characterized in that: on the plunger rod 2, the end close to the push-pull handle 4 is fixedly sleeved with a limiter. The position ring 7, the elastic air bag 8 sleeved on the plunger rod 2 is sealingly connected between the spacer ring 7 and the blocking plate 6, and the elastic air bag 8 is communicated with a buffer bag 9 for relieving pressure through a thin hose. The buffer bag 9 and the elastic air bag 8 are detachably connected. In the anti-pollution syringe provided by the utility model, the plunger rod 2 and the sealing plug 3 do not touch the hands of the operator or the outside air during the dispensing process, which can effectively prevent cross-contamination of the liquid medicine when the syringe is operated, ensuring The medicine is safe, the structure is simple, and it is suitable for popularization and application.
