Puncture device having positioning adjustment structure for chemotherapy

Abstract

The invention discloses a puncture device having a positioning adjustment structure for chemotherapy. The technical solution is as follows: the device comprises an adsorption seat, the adsorption seatis equipped with a pressing mechanism, and through the pressing mechanism, negative pressure can be generated in the adsorption seat to realize adsorption; and a rotary positioning mechanism for positioning the puncture needle is installed on the adsorption seat, the rotary positioning mechanism is provided with a movable extrusion mechanism, and the movable extrusion mechanism presses or loosensthe puncture needle to adjust the infusion speed. The device provided by the invention solves the problems that a puncture needle cannot be effectively positioned and an infusion speed is not easilyadjusted in the prior art, can be stably adsorbed on skin of a patient and position a puncture needle, and facilitates stable insertion of the puncture needle into an infusion port; and the device canconveniently adjust the infusion speed to make the infusion speed be within a tolerance range of the patient.

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...

AI Technical Summary

Problems solved by technology

[0004] 1) When the existing puncture device for chemotherapy is used, it is generally necessary for the staff to press the device with their hands, so as to avoid that the device is not easy to be stably adsorbed on the affected part of the patient due to the tension of the patient, which is not conducive to the use of the puncture device by the staff ;

[0005] 2), when the existing puncture device for chemotherapy is in use, it is not convenient to locate the puncture needle, which makes it difficult for the puncture needle to be stably inserted into the infusion port during chemotherapy, which is not conducive to the progress of chemotherapy, and will increase the number of patients. pain of;

[0006] 3), when the existing puncture device for chemotherapy is used, the speed of chemotherapy cannot be controlled, and the speed of infusion will be different when it is used for different patients' physique, and it will also be different when it can withstand chemotherapy. During chemotherapy, the infusion speed is faster, which will not only increase the pain of the patient, but also easily cause the patient to be injured
