Drainage tube for hydrops extraction

Technical Field

The invention relates to the field of medical equipment, in particular to a drainage tube for effusion extraction.

Background

The endocrinology department is a place special for treating diseases of the endocrinology department in hospitals and is mainly responsible for clinical diagnosis and treatment of diabetes, obesity, osteoporosis, gout, lipid metabolism disorder, diseases of thyroid, pituitary, adrenal gland, gonad, parathyroid gland and the like.

In clinical treatment, drainage is often required to drain a fluid accumulated in a human body by drainage, which is a process and method of drawing a fluid from a body cavity or wound by gravity or gravity. The common drainage of gauze strips in the medical clinical field and nursing is that the common drainage of gauze strips is to put an aseptic gauze strip into a superficial wound or a cut pus cavity, one end of the aseptic gauze strip is left outside the wound to discharge wound liquid, the drainage quality is not high, the tissue is stimulated, the possibility of causing infection exists, the common rubber tube drainage is to insert a latex tube with one end provided with a plurality of small holes in a cut mode into a deep wound cavity or a deep body cavity, and the drainage quality is better compared with the gauze drainage.

The department of hepatopathy uses the pleural effusion drainage tube mainly used to drain the air or liquid in the thorax, the drainage head of the pleural effusion drainage tube for the department of hepatopathy that has now is circular, often has a plurality of apertures to prevent to block up through opening on its lateral wall, but this kind of aperture size is less, inhales human tissue easily, prevents stifled unsatisfactory effect, not only makes nurse's work load increase, has increased the chance of thoracic cavity infection moreover, causes unnecessary misery to the patient.

A pleural effusion drainage tube for hepatopathy department as mentioned in utility model patent publication No. CN205626694U, comprising: the end of the pipe body is provided with an end head; the end comprises an inner drainage tube and an outer support tube which are coaxially arranged, and a connecting rib which connects the outer support tube to the inner drainage tube, the inner drainage tube is connected with the tube body, at least one first drainage hole is arranged on the tube wall of the inner drainage tube along the axial direction of the inner drainage tube, a drainage groove is arranged on the tube wall of the outer support tube along the axial direction of the outer support tube, a second drainage hole is arranged on the outer support tube, and the second drainage hole is positioned at each connecting rib and penetrates through the connecting rib and the inner drainage tube; the end of the end is a suction hole, an image shooting module is arranged at the suction hole of the end, a wireless transmitter is arranged on the image shooting module, and the image shooting module transmits image data to external control and display equipment through the wireless transmitter. The utility model discloses simple structure, convenient to use, and it is accurate to attract hydrops location, effectively alleviate patient's misery.

Because its image shooting module for the drainage tube structure is complicated, greatly increased the cost of drainage tube, be unfavorable for the large tracts of land to promote.
