Compound puncture drainage needle

Abstract

The invention discloses a compound puncture drainage needle, which mainly comprises a guiding needle and an indwelling hose, wherein the guiding needle is sleeved in the indwelling hose; the front end of the guiding needle penetrates through the indwelling hose; the front end of the indwelling hose is tightly matched with the guiding needle, a flow passage gap is formed between the other parts of the indwelling hose and the guiding needle, a rubber plug is arranged at the tail part of the indwelling hose, and the tail end of the guiding needle penetrates through the rubber plug; at least one flow passage hole is arranged on a guiding needle wall, on which the flow passage gap is formed; and the side wall of the indwelling hose is provided with a drainage branch tube and a back wash branch tube. The compound puncture drainage needle is convenient for use, simplifies the operational process, reduces the technical requirement on a doctor, and can ensure the puncture in position once, avoid the damage to tissues due to too deep puncture and the pain of a patient due to repeated puncture, draw hydrops of the patient quickly and safely, be convenient for indwelling, draw blood repeatedly for examination or treatment, and be used for injecting medicaments; and the indwelling hose does not fall off and is safe and reliable.

Description

technical field [0001] The invention relates to a composite puncture and drainage needle, which belongs to the technical field of medical equipment. Background technique [0002] Puncture and drainage are often used in medical treatment. On the one hand, it can be used to analyze the patient's body fluids to find out the lesion; on the other hand, it can also extract excess fluid from the patient's body as a treatment plan. For different purposes, the schemes of puncture and drainage are different. Analysis The drainage of the patient's effusion is often one-time. In clinical practice, a small amount of effusion is extracted with a disposable syringe for inspection and analysis. Pain and fear may also cause complications such as bleeding, infection and damage to organs. Drainage as a treatment plan often has a time period, that is, continuous and repeated drainage is required within a certain period of time, and the drainage needle part at this time needs to be left in the...

AI Technical Summary

Problems solved by technology

[0003] It can be seen from the above operation steps that the existing indwelling puncture needles are cumbersome to operate, have high technical requirements for doctors, increase the workload of medical staff, and also significantly increase the chances of complications such as bleeding, infection, and damage to organs, which will cause serious problems for patients. cause greater pain

The complexity of the puncture and drainage device itself will also increase the cost and cause economic losses.
