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 the device being difficult 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) The existing puncture device for chemotherapy is not convenient for positioning the puncture needle, which makes it difficult for the puncture needle to stably penetrate into the infusion port during chemotherapy, which is not conducive to the progress of chemotherapy and will increase the patient's pain;
[0006] 3) When the existing puncture device for chemotherapy is in use, the speed of chemotherapy cannot be controlled. It is used for different patients with different physiques, and the speed of infusion when they can withstand chemotherapy will also be different. When the infusion rate is fast, it will not only increase the pain of the patient, but also easily cause the patient to be injured.

Embodiment 1
[0041] Attached below Figure 1-Figure 9 The present invention is described in detail, specifically, the structure is as follows:
[0042] This embodiment provides a puncture device for chemotherapy with a positioning adjustment structure, including an adsorption seat, a pressing mechanism, a rotating positioning mechanism and a movable extrusion mechanism. The pressing mechanism can generate negative pressure in the adsorption seat to realize adsorption; The mechanism is used to position the puncture needle 10, and the movable squeezing mechanism adjusts the infusion speed by squeezing or loosening the puncture needle 10.
[0043] In order to facilitate adsorption to the human body without causing damage to the human body, the adsorption seat is arranged in a ring structure, that is, the adsorption seat includes a support ring 1 and a connecting ring 2, such as figure 1 with figure 2 As shown, the connection ring 2 is fixed above the support ring 1 , and the inner diameter...

The invention discloses a puncture device for chemotherapy with a positioning adjustment structure, which solves the problems in the prior art that the puncture needle cannot be effectively positioned and the infusion speed is difficult to adjust, can be stably adsorbed on the patient's skin, and can be used for puncture The positioning of the needle is convenient for stably inserting the puncture needle into the infusion port; it is convenient to adjust the infusion speed so that the infusion speed is within the tolerance range of the patient; , the negative pressure can be generated in the adsorption seat through the pressing mechanism to realize the adsorption; a rotary positioning mechanism for positioning the puncture needle is installed above the adsorption seat, and the rotary positioning mechanism has a movable extrusion mechanism, and the movable extrusion mechanism can squeeze Or loosen the puncture needle to adjust the infusion rate.
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...
