Description

technical field

[0001] The invention relates to the field of medical auxiliary equipment, in particular to a puncture device for chemotherapy with a positioning adjustment structure. Background technique

[0002] Chemotherapy is a method of treating cancer with chemical drugs. It injects chemical drugs into the affected part of the patient through chemotherapy equipment, and kills cancer cells through chemical drugs. Although chemotherapy can kill cancer cells, it can also kill normal cells. Therefore, a series of complications will appear in the body of the patient who has undergone chemotherapy. The puncture device for chemotherapy is a device that punctures the affected part of the patient on the chemotherapy equipment.

[0003] The inventors have found that the existing puncture device for chemotherapy also has the following problems in use:

[0004] 1) When the existing puncture device for chemotherapy is used, it is generally necessary for the staff to press the devic...
