Description

Technical Field

[0001] The utility model belongs to the technical field of needle tube sealing covers, and particularly relates to an anti-overflow sealing cover for a syringe. Background Art

[0002] The anti-overflow sealing cover for syringes is mainly used for syringes of intravenous chemotherapy drugs. Chemotherapy drugs are cytotoxic drugs and need to be prepared in a specific environment and use special packaging bags. After intravenous chemotherapy drugs are prepared, it is easy for them to be poorly sealed, resulting in drug loss. It will also pollute the environment and cause occupational injuries to the staff. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a syringe anti-overflow sealing cover, which can temporarily seal the syringe of intravenous chemotherapy drugs through the sealing plug to reduce the overflow of chemotherapy drugs.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A syringe overflow prevention sealing cover comprises a boss, a fixing cap and a sealing plug. The boss is fixedly provided with a fixing cap on one side, and the fixing cap is fixedly provided with a sealing plug on one side. The fixing cap is used to fix the entire cover body on the injection needle tube to prevent drug overflow. When the drug needs to be pushed out of the needle tube, the boss is pulled to remove the entire sealing cover, so that the fixing cap is separated from the needle tube, and the front end of the needle tube is sealed by the sealing plug.

[0006] Preferably, the interior of the sealing plug is made of rubber material, which can provide a tighter seal when sealing the front end of the needle tube.

[0007] Preferably, a rotating bar is fixedly provided on the outer side wall of the sealing plug and the fixing cap, and the rotating bar is used to facilitate taking out the entire sealing cover.

[0008] Preferably, the fixing cap and the sealing plug are both conical in shape, so as to be easily fixed on the needle tube and prevent them from falling off.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The sealing plug can be used to temporarily seal the syringe of intravenous chemotherapy drugs, and then connected to the intravenous instrument when used clinically, ensuring the safety of the intravenous chemotherapy syringe, reducing the spillage of chemotherapy drugs, and improving the occupational protection of medical staff.

[0014] The following will be combined with the attached embodiment of the present utility model Figure 1-2 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] A syringe overflow prevention sealing cover comprises a boss 1, a fixing cap 2 and a sealing plug 3. The boss 1 is fixedly provided with the fixing cap 2 on one side, and the fixing cap 2 is fixedly provided with the sealing plug 3 on one side. The fixing cap 2 is used to fix the entire cover body on the injection needle tube to prevent drug overflow. When the drug needs to be pushed out of the needle tube, the boss 1 is pulled to remove the entire sealing cover, so that the fixing cap is separated from the needle tube, and the front end of the needle tube is sealed by the sealing plug 3.

[0016] The interior of the sealing plug 3 is made of rubber material, which can seal the front end of the needle tube more tightly.

[0017] A rotating bar 4 is fixedly provided on the outer side wall of the sealing plug 3 and the fixing cap 2, and the rotating bar 4 is used to facilitate taking out the entire sealing cover.

[0018] The above content has shown and described the embodiments of the utility model. For those skilled in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle of the utility model. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should belong to the protection scope of the utility model.
