Abstract

The utility model relates to a sealing rubber ring of a hole of a traction pin, which belongs to a medical sealing device of the hole of a traction pin. The utility model is characterized in that a median raised rubber ring is molded by the raw material of silicon rubber and latex; a groove of the hole of a traction pin is arranged on the center of the rubber ring, and air holes are uniformly distributed around the hole of a traction pin. The utility model has the advantages that the infection rate can be evidently reduced; the effect of the hole of a traction pin sealed with rubber ring is exact, and the sterile level of the utility model is high; the utility model can be used for clinic to meet the requirements of the seal of the pin hole of Steadite pins.

Description

Sealing rubber ring of hole of tractor pin

This utility model belongs to the locking device in medical fine steel needle hole.

On the clinical skeletal traction of orthopaedics, the extensive use sterile gauze applies lid, the fixed method of zinc oxide adhesive plaster at present.Traction therapy of bone needs the time in 6～8 weeks clinically, so adopt above-mentioned pin hole sealing method, because gauze directly contacts with air, the ethanol for disinfection volatilization of pin hole place drop is very fast again, do not reach the purpose of pin hole place strict sterilization, gauze directly exposes body surface, be easy to pollute, and zinc oxide adhesive plaster comes off easily, make gauze separate with skin, cause that pin hole exposes etc., promptly do not meet strict aseptic requirement like this, can cause deep tissue to infect again.

In order to overcome the shortcoming of above-mentioned existence, this utility model provide a kind of during treating difficult drop-off, the sealing cushion rubber that aseptic degree is high.

This utility model is achieved in that

Adopting medical grade silicon rubber or latex is raw material, is molded into the cushion rubber (referring to Fig. 1) of median rise.The diameter of cushion rubber is 65～75 millimeters, and median rise part (1) diameter is 45～55 millimeters, is concave-convex, and the thickness of cushion rubber is 0.5～3 millimeter, and there is the not saturating hole slot of threading a needle (3) at the cushion rubber center, and the diameter of hole slot (3) is 3～5 millimeters.Be distributed with 6～10 air-vents (2) around the centre bore equably, so that the skin eupnea in the assurance cushion rubber, the diameter of air-vent (2) is 2～4 millimeters, be sidelong at cushion rubber bump (1) recessed that to put a thickness be 2～4 millimeters, diameter is the cotton pad of 43～53 millimeters medical absorbent cotton, and it is 2～4 millimeters the hole of threading a needle (4) that there is a diameter centre of circular cotton pad.By the formed cavity of bump (1) (6) degree of depth is 2～5 millimeters.

Appearance of the present utility model can reduce infection rate significantly, the definite effect of cushion rubber sealing pin hole, aseptic degree height, it is simple in structure, and is easy to use, cost is low, can be widely used in clinically this, the needs of Kirschner wire pin hole sealing.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a cotton pad sketch map of the present utility model.

1 is the bump of cushion rubber among the figure, the 2nd, and air-vent, the 3rd, hole slot, the 4th, the hole of threading a needle, the 5th, brush coating face.

Behind the cushion rubber die forming, be brushed with adhesive of medical equably on the brush coating face (5) around the cushion rubber, cotton pad is put into the recessed side of bump (1).Per two cushion rubbers are to lumping together, and the centre is separated with plastic sheeting, and sealing in the plastic bag of packing into is then with physical method sterilization (cut off plastic bag, directly use under asepsis) when using clinically.

During use cushion rubber is penetrated in the pin end at the hole place of threading a needle, make different-diameter this, Kirschner wire all can connect airtight in cushion rubber, and is and smooth, be bonded in securely on the skin of human body, to keep good closed performance.Every day, the air-vent (2) from cushion rubber splashed into ethanol, and it is aseptic to make pin hole locate skin on every side.
