Abstract

The utility model relates to a multi-head self-destructing syringe, which relates to the field of medical equipment. It is composed of a needle tube and a pusher rod. The pusher rod is inserted into the inside of the needle tube. To the inner side of the needle tube, a self-destruct blade is longitudinally arranged on the inner edge of the propulsion wing, the direction of the self-destruct blade facing the needle connecting tube is the direction of the blade, there is a propulsion plug on the top of the propulsion rod, and there is a propulsion piece at the tail of the propulsion rod, and the diameter of the propulsion piece is larger than the needle tube outside diameter. The utility model can directly pull out the push rod after the medical personnel complete the injection operation, and use the added self-destruct blade to form a cut on the push plug, so that the syringe cannot continue to be used. At the same time, the inverted tapered design of the needle connecting tube can increase the flow rate when the drug enters the needle tube, so that two or more synergistic drugs can be quickly fused, and when the drug is pushed into the body, it can reduce the flow rate. The pushing speed reduces the instantaneous stimulation of the drug to the human body.

Description

Multi-head self-destructing syringe

technical field

The utility model relates to the field of medical equipment, in particular to a multi-head type self-destruction syringe.

Background technique

With the country's restrictions on intravenous injection, the utilization rate of syringes is getting higher and higher, and it is not uncommon to inject multiple synergistic drugs at one time in the medical process. At the same time, in order to avoid cross-infection, syringes are disposable items. After use, medical waste needs to be destroyed uniformly to avoid secondary use. However, there are still some criminals who steal syringes for other purposes, endangering public safety.

Contents of the invention

The utility model provides a multi-head type self-destructing syringe for the deficiency of the above-mentioned prior art.

The multi-head self-destructing syringe of the utility model is composed of a needle tube and a push rod, the needle tube is a hollow tube with a lower opening, the push rod is inserted into the inside of the needle tube, and two or more The needle connecting tube is an inverted tapered tube with upper and lower openings. The edge of the tail of the needle tube is provided with a propulsion wing, which extends to the inner side of the needle tube. The direction of the needle connecting tube is the direction of the blade. The top of the push rod is provided with a push plug whose outer diameter is the same as the inner diameter of the needle tube. The tail of the push rod is provided with a push piece whose diameter is greater than the outside diameter of the needle tube.

As a further improvement of the utility model, the diameter of the tail of the needle connecting tube is 1/2 of the diameter of the head.

As a further improvement of the present utility model, the head of the needle connecting tube is provided with a cover.

The multi-head type self-destructing syringe of the utility model can directly pull out the push rod after the medical personnel complete the injection operation, and use the added self-destruct blade to form an incision on the push plug, so that the syringe cannot continue to be used. Once the push rod is pulled out , due to the unique design of the position of the self-destruct blade, other push rods cannot be sent into the inside of the needle tube. At the same time, the inverted tapered design of the needle connecting tube can increase the flow rate when the drug enters the needle tube, so that two or more synergistic drugs can be quickly fused, and when the drug is pushed into the body, it can reduce the flow rate. The pushing speed reduces the instantaneous stimulation of the drug to the human body.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

As shown in Figure 1, the multi-head self-destructing syringe of the present utility model is composed of a needle tube 1 and a push rod 2. The needle tube 1 is a hollow tube with a lower opening, and the push rod 2 is inserted into the inside of the needle tube 1, and the needle tube The head of 1 is provided with two or more needle connecting tubes 3, which are used to inhale multiple synergistic drugs at the same time. The diameter of the tail of 3 is set to half of the diameter of the head, so that when the drug enters the inside of the needle tube, the flow rate is increased, so that the synergistic drugs can be quickly fused, and when the drug is pushed into the body, the pushing speed can be reduced , to reduce the instantaneous stimulation of the drug to the human body. The head of the needle connecting tube 3 is provided with a cover 8, which can be used to close the needle connecting tube 3 when not in use. The edge of the tail of the needle tube 1 is provided with a propulsion wing 4, and the propulsion wing 4 extends to the inner side of the needle tube 1, and the edge of the inner side of the propulsion wing 4 is longitudinally provided with a self-destruct blade 5, and the direction of the self-destruct blade 5 facing the needle connecting tube 3 is the blade direction , when the medical staff completes the injection operation, they directly pull out the push rod, and use the added self-destruct blade to form an incision on the push plug, which makes the syringe unusable. Once the push rod is pulled out, due to the unique design of the self-destruct blade position, Other propelling rods also cannot be sent into the inside of the needle tube, which has played a blocking role. The top of the pusher rod 2 is provided with a pusher plug 6, the outer diameter of the pusher plug 6 is the same as the inner diameter of the needle tube 1, and the afterbody of the pusher rod 2 is provided with a pusher piece 7, and the diameter of the pusher piece 7 is greater than the outer diameter of the needle tube 1. When injecting, it is sufficient to push the propulsion piece 7 forward. At the same time, because a plurality of needle connecting tubes 3 are arranged, the positions of the needle connecting tubes 3 are arranged on the edge of the top surface of the needle tube 1, so that the injection angle is more favorable.

The up, down, left, right, horizontal, and vertical directions mentioned in the above description are all described from the perspective of the accompanying drawings.
