Abstract

Provided is a fixing device for a drainage catheter. The fixing device includes three parts: a fixing pedestal, an annular support and a screw knob. The fixing pedestal is integrally formed by the connection between an annular sheet with a central hole and an annular column; the annular sheet is provided with a flat pasting member fixed on the body of the patient; the top of the peripheral part of the annular column is provided with a screw-socket; and the wall of the annular column is provided with multiple vertical grooves with different width. The annular support is composed of two annular columns; and multiple connecting members with same thickness and different width are integrally formed between the two annular columns. One ends of the connecting members are provided with multiple grooves; the width of the grooves is one-to-one corresponding to that of the grooves on the fixing pedestal. The connecting members can sleeve on the annular column of the fixing pedestal. The grooves on the connecting members and the fixing pedestal form a clamping mechanism, and then close for forming a circular or other shaped hole and form a hole for clamping the drainage catheter tightly at the side surface. A screw knob corresponds to the screw-socket on the top of the peripheral part of the annular column of the fixing pedestal. The annular support is locked by the displacement of the screw knob, so that the grooves on the connecting members and the fixing pedestal are closed for clamping and fixing the drainage catheter tightly.

Description

Drainage catheter fixer

Technical field

This utility model relates to and belongs to field of medical technology, particularly a kind of fixture of drainage catheter

Background technology

After clinical implementation operation, in most cases all need indwelling drainage tube or other medical catheter, general indwelling 2-15 days, reaches one sometimes to the several months.During drainage tube indwelling, the key of the unobstructed successful surgery often of drain, Rehabilitation, because once these drainage catheter displacements come off, the lighter causes the misery of second operation to patient, reappose drainage catheter, delay treatment effect and time, severe one forms abscess and infects, jeopardize patient's life, in the past, in hospital clinical, adopt traditional method to fix drainage tube, the general suture seam skin that adopts is fixed, assist and fix with adhesive plaster, gauze again, there is following problem in this method: 1, easily punctures doctor's patient skin, cause nosocomial infection; 2, easily cause tractive pain or lacerated wound, cause patient's pain and anxiety; 3, complex operation, inconvenient clinical observation and wound cleaning sterilization; 4, owe firmly, lack of standardization, increase medical worker's workload.

At present clinically, the open drainage tube fixing device using has two kinds: the first patent No. is 201020201511.7, the drainage catheter fixer parts of the disclosure all adopt duroplasts to make, parts are more, make this fixture volume area larger, because parts are more, structure is comparatively complicated, it is extremely inconvenient to install and use, and increases medical worker's workload; In actual use, the outlet of drainage catheter, on top, is easily converted into dead angle, and the height that whole device exposes is higher, and stature is larger, and patient very easily touches to mix and produces moment and coming off, and causes burden at heart to patient, affects patient's emotion.The second patent No. 201120041947.9, the drainage catheter fixer parts of the disclosure adopt duroplasts buckle and silica gel piece to make, this fixture is difficult for ventilative, therefore the wound at patient's drainage tube place can not be in dry environment, increase the probability of wound contamination, unfavorable wound healing, and can not directly clear up wound and change dressings; In addition, when the fixing drainage tube of this fixture, the vertical skin of drainage tube, is very easily converted into dead angle, affects drainage effect; In actual use, because silica gel has very strong elasticity, can not avoid tractive pain, and run into body fluid and cause stator and sticker Paint Gloss between the two, very easily because external force traction separates slippage.

In addition, clinically, sometimes place two drainage tubes at place's wound, above two kinds of drainage catheter fixers all cannot use.

Summary of the invention

In order to overcome and to solve existing drainage catheter fixer deficiency and drawback clinically, therefore special design has been invented this utility model drainage catheter fixer, this utility model provides a kind of fixture that ensures the fixing drainage catheter of safety, substituting seam skin fixes, can fix two drainage tubes, the drainage tube that directly goes out, tiltedly goes out all can be fixed, transparent air-permeable simultaneously, fixation, can directly change dressings and clean wound.
