Special talcum powder spraying device for pleurodesis

Abstract

The invention discloses a special talcum powder spraying device for pleurodesis. The special talcum powder spraying device comprises a talcum powder spraying cavity, one end of the talcum powder spraying cavity is connected with a first connection hose, one end of the first connection hose is fixedly connected with one end of a second connection hose, and the first connection hose is provided withan adhesive tape. The other end of the second connection hose is connected with one side of a nozzle, the other side of the nozzle is provided with spraying holes distributed at equal intervals, anda small air pump is fixedly mounted on the outer wall of the talcum powder spraying cavity. A piston rod is fixedly connected with one side of a push block which is arranged in a talcum powder storagebox, one end of the piston rod is connected with the small air pump at the outer end, the small air pump drives the piston rod to move to drive the push block to move towards one side, and thus, talcum powder is pushed into the first connection hose, automatic powder treatment is realized, and the problem of low efficiency caused by manual operation is avoided.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a talcum powder spraying device special for pleura fixation. Background technique [0002] Malignant pleural effusions are often encountered in clinical thoracic surgery. Malignant pleural effusions will occur after a variety of malignant tumors are metastasized to the pleural cavity. It is characterized by fast production speed, pressure on the lungs and difficulty breathing. At the same time, due to the exudation of a large number of blood cells and proteins, Tumor patients consume a lot of energy, and patients often die from rapid consumption of large amounts of pleural effusion. [0003] For patients with malignant pleural effusion, the most commonly used clinical palliative procedure called pleurodesis is to spray high-temperature sterilized medical talcum powder into the chest cavity in order to stimulate the aseptic inflammation in the chest cavity through talcum powder The reac...

AI Technical Summary

Problems solved by technology

[0004] The most important step of the operation is to spray talcum powder after the pleural effusion is sucked, which requires a talcum powder spraying device, but there are certain deficiencies in the existing talcum powder spraying device during use, for example: 1. The total amount of talcum powder cannot be controlled more accurately. Excessive spraying of talc powder is not beneficial to control symptoms, but aggravates symptoms such as chest pain; The size is different, the distribution is random, and it is easy to spray unevenly, resulting in uneven adhesion of the chest cavity and affecting the surgical effect; 3. Manual spraying can not keep the spraying speed and intensity consistent, resulting in uneven spraying and affecting the surgical effect
