Problems solved by technology

In hospitals, especially some large hospitals, medical staff need to prepare a large amount of cytotoxic liquid medicine for patients every day. Due to the current dispensing method, the dispensing needle does not have a closing device. When dispensing cytotoxic drugs, cytotoxic drug aerosol or drug Liquid droplets are easy to spread into the dispensing environment, which will inevitably cause great harm to the dispensing personnel

Embodiment 1

[0031] Embodiment 1, a safe dispensing needle for cytotoxic drugs, including a needle holder 7, characterized in that one end of the needle holder 7 is fixedly connected with a needle tube 1, and the needle tube 1 is provided with an elastic sealing device.

[0032] When using this embodiment, refer to the attached figure 1 , insert the needle tube 1 into the vial of cytotoxic drug, configure the drug, and the elastic sealing device closes the gap between the rubber stopper of the vial and the dispensing needle, so as to prevent the cytotoxic drug aerosol and liquid in the vial from spreading to the dispensing environment Middle; after the cytotoxic drug is prepared and the drug solution in the bottle is pumped out, the cytotoxic drug on the needle tube and the drug solution in the needle tube cannot be spread into the dispensing environment through the elastic sealing device, so as to protect the safety of the dispensing personnel.

Embodiment 2

[0033] Embodiment 2. On the basis of Embodiment 1, the elastic sealing device is made of materials such as silica gel, rubber, elastic TPN, and elastic TPE2.

[0034] When using this embodiment, refer to the attached figure 1 , when inserting into the vial of cytotoxic drugs, the elastic sealing device 2 is fixed by hand, and when the needle tube is pulled out, the elastic sealing device 2 makes the cytotoxic drug in the vial, the cytotoxic drug on the needle tube and the drug in the needle tube The liquid medicine cannot be spread into the dispensing environment, thus protecting the safety of the dispensing personnel.

Embodiment 3

[0035] Embodiment 3, on the basis of Embodiment 2, the elastic closure device includes a return spring 3 fixedly connected between the needle holder 7 and the elastic closure device 2 .

[0036] When using this embodiment, refer to the attached figure 2 , when inserted into the vial of cytotoxic drugs, the elastic closure device 2 overcomes the elastic action of the return spring 3, and after dispensing is completed, under the action of the return spring 3, the elastic closure device 2 can avoid the harm of cytotoxic drugs to the dispensing personnel .

Abstract

The invention relates to the field of medical instruments, in particular to a safe dispensing needle for cytotoxic drugs, which comprises a needle tube, a needle tip arranged at the front end of the needle tube, a dispensing hole arranged at the front end or on the side wall of the needle tube, a needle seat fixedly connected with the rear end of the needle tube, and an elastic sealing device on the outer side of the needle tube. The needle tube is a hollow cavity inside, a cavity is formed in the needle seat and communicated with the cavity of the needle tube, the dispensing hole is communicated with the cavity in the needle tube and the cavity in the needle seat, the elastic sealing device is arranged on the outer side of the needle tube in a sleeved mode to seal the dispensing hole, and an elastic reset device is arranged between the elastic sealing device and the needle seat. The device is simple in structure and reasonable in design, and when the cytotoxic medicine in the penicillin bottle is prepared, the needle tip penetrates through the elastic sealing device and is further inserted into a rubber plug of the penicillin bottle to dissolve and suck the medicine. After the preparation is finished, the medicine in the penicillin bottle is completely pumped, the needle tube is pulled out, and the dispensing hole on the dispensing needle tube is automatically sealed by manually pushing the elastic sealing device or an elastic resetting device, so that the leakage of cytotoxic medicine aerosol is prevented, and the safety of dispensing personnel is protected.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, in particular to a safe dispensing needle for cytotoxic drugs. Background technique [0002] Hospital nurses need to prepare different cytotoxic drugs into infusion bags according to the drug requirements of tumor patients, and then infuse them into the patient's body. In hospitals, especially some large hospitals, medical staff need to prepare a large amount of cytotoxic liquid for patients every day. Due to the current dispensing method, the dispensing needle does not have a sealing device. When dispensing cytotoxic drugs, cytotoxic drug aerosol or drug Liquid droplets are easy to spread into the dispensing environment, which will inevitably cause great harm to the dispensing personnel. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a safe dispensing needle for cytotoxic drugs, which solves the above...
