Embodiment 1

[0035] Such as figure 1 , 2 As shown, in this embodiment, the buffer syringe of the present invention includes an outer bracket 2 , a top cover 1 , a protective cover 3 , an inner body 4 and a fitting mechanism 5 .

[0036] The top cover 1 is wrapped outside the inner body 4, the outer bracket 2 is outside the top cover 1, the top cover 1, the outer bracket 2 and the protective cover 3 are combined into a closed and sterile independent space, and the inner body 1 is covered together. its interior.

[0037] The inner main body 4 is fixed on the opposite side of the fitting mechanism 5, and the inner main body 4 includes a medicine chamber 17 which can hold the medicinal liquid. In this embodiment, the drug storehouse 17 is in the shape of an inverted cone. In this embodiment, the capacity of the medicine compartment is 0.2-0.3 milliliters.

[0038]The middle part of the bottom of the drug storehouse 17 is open and extends downward to form an indwelling tube 11, wherein the ...

Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that the buffer syringe in this embodiment does not include components such as the external support 2, the protective cover 3, the firing button 13, the main spring 14, and other structures in this embodiment are the same as those in Embodiment 1. Same, no more details here.

[0052] Compared with Embodiment 1, the structure of the buffer injector in this embodiment is simpler. During the injection, the guide needle 10 is pierced into the skin of the human body through the force of the operator's hand, and the subsequent use process is similar to that of Embodiment 1.

Abstract

The invention relates to a buffering injector, which comprises a joining mechanism (5), an internal main body (4) and a top cover (1), wherein the internal main body (4) is fixed on the backside of the joining mechanism (5); the internal main body (4) comprises a medicine cabin (17) for containing medicine liquid; the bottom of the medicine cabin (17) is open and extends downwards to form a retention tube (11); the retention tube (11) passes through the joining mechanism (5) to continue to extend downward; the top part of the medicine cabin (17) is covered by a diaphragm (6); the top cover (1) is fixed with a guide needle (10); the guide needle (10) passes through the diaphragm (6) to enter the medicine cabin (17); the needle head part of the guide needle (10) extends out of the retentiontube (11); and the guide needle (10) is tightly jointed with the retention tube (11) and moves up and down in the retention tube (11). The buffering injector integrates the advantages of a hypodermicsyringe and an intravenous injector. The buffering injector has a simple structure, is convenient to operate and can allow medicines to be absorbed smoothly with a desirable absorption effect.

Description

technical field [0001] The present invention relates to a buffer syringe for subcutaneous injection. Background technique [0002] At present, the commonly used injection methods mainly include subcutaneous injection and intravenous injection. [0003] Subcutaneous injection is a method of injecting medicinal liquid into the subcutaneous tissue of the human body. When performing subcutaneous injection, the syringe relies on external force to inject the liquid medicine into the subcutaneous tissue, and the injection speed is very fast, usually within a few seconds. After the medicinal liquid enters the human body, the drug concentration in the body generally reaches the highest peak in about 30 minutes, and then begins to decrease rapidly. The advantage of the hypodermic syringe is that the injection operation is relatively convenient, but the disadvantage is that the drug is absorbed too quickly and cannot be absorbed smoothly by the body. And the injection of some medici...
