Abstract

A pin-tract infection prevention device relates to the device used with orthopedic external mounting bracket, belonging to medical instrument technical field, which is applicable in solving the pin-tract infection problem during the usage of external mounting bracket. The proposal comprises a cyst pad and a shunt body; a mounting pin hole is arranged on the cyst pad, and on one side of the pad surface are distributed a plurality of oozed-liquid pores; the cyst pad and the shunt body are communicated through a soft tube, and a liquid-filled hole is arranged on the shunt body. The utility body has the cyst pad as the carrier of medical liquor, and uses the cyst pad characteristic that the cyst surface can maintain good contact with skin to drain the medical liquor from the oozed-liquid pores on the cyst surface to pin-tract site which is liable for infection; sustaining or interrupt alcohol disinfection and sterilization to the pin-tract site can nicely solve the problem that pin-tract infection is hard to avoid and control during the usage of external mounting bracket; the utility model also has the advantages of simple and light structure, convenient manufacture, allocation and usage, decrease in the amount of plenty disinfection and care work during wearing an external mounting bracket, and facilitation on bone fracture healing; the utility model is suitable for the allocation and usage as the accessory of orthopedic external mounting bracket.

Description

Prevention pin track infection utensil

Technical field

This utility model relates to a kind of and the matching used utensil of orthopaedics external fixer, belongs to the armarium technical field.

Background technology

External fixer is orthopaedics utensil commonly used when fracture is undergone surgery reduction therapy, during use staple being passed through integumentary musculature implants in the sclerotin, fix its position by external fixer then, knochenbruch is resetted and fixing on the tram, remove external fixer after the healing again.External fixer is followed closely the place, road around the integumentary musculature of staple and is easy to infect in the very long process of following the knochenbruch healing, and the infection focus position is developed to diaphysis along the nail road when serious, causes osteomyelitis.Control infection for this reason except that oral, injection antimicrobial drug, also must be often be embrocated alcohol disinfecting and with aseptic dressing wrapping nail place, road to each nail place, road.Even this kind disinfected more than a day time, can not guarantee that the place of nail is in disinfection all the time, simultaneously and since patient's more options wear external fixator from institute's therapeutic modality, so be difficult to carry out timely and effectively the alcohol disinfecting processing especially.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of prevention pin track infection utensil, the pin track infection problem in using with effective solution external fixer.

The alleged problem of this utility model realizes with following technical scheme:

A kind of prevention pin track infection utensil, its unique distinction is, be provided with capsule pad 1 in the formation, divide fluid 2, the capsule pad is provided with on staple hole 3, the side pad face and is distributed with sepage aperture 4 around staple hole 3, capsule pad 1 is connected by flexible pipe 5 with dividing between the fluid 2, divides fluid 2 to be provided with liquid injection hole 6.

Above-mentioned prevention pin track infection utensil, described staple hole 3 are U-shaped opening slotted eye.

Above-mentioned prevention pin track infection utensil, the sphere capsule pad of described capsule pad 1 for caving inward, described sepage aperture 4 is distributed on the sphere of depression.

Above-mentioned prevention pin track infection utensil, the aperture of described sepage aperture 4 is 0.5～1 millimeter.

This utility model is the medicinal liquid carrier with the capsule pad, utilize the capsule face of capsule pad medicinal liquid to be drained into place, susceptible nail road by the sepage aperture on the capsule face with the characteristic that skin flesh place keeps well contacting, nail place, road is implemented the alcohol disinfecting sterilization treatment of uninterrupted or discontinuous, so solved well external fixer use in pin track infection be difficult to the difficult problem avoiding and control, and it is simply light to have formation, makes and settles advantages such as easy to use; Adopt the pin track infection that can effectively prevent behind this utility model to wear during the external fixer, reduce a large amount of disinfection nursing workloads, make knochenbruch keep good butt joint growing environment, promote the knochenbruch healing, suitablely use as settling at orthopaedics external fixer adnexa.

Component part numbers is in the accompanying drawing: 1-capsule pad, 2-divide fluid, 3-staple hole, 4-sepage aperture, 5-flexible pipe, 6-liquid injection hole, 7-staple, 8-locknut, 9-external fixer.

The specific embodiment

Consult Fig. 1,4.Capsule pad 1 in the formation can be circle, polygon etc., and quantity is some.Divide the multi-path fittings body in the fluid 2 similar pipe fittings, each capsule pad 1 is connected with a path mouth in the branch fluid 2 by flexible pipe 5.The path mouth of capsule pad 1 and branch fluid 2 is consistent with the quantity of employed staple 7 in the external fixer.

Consult Fig. 1,2.Being advisable with U-shaped open slot well format in staple hole 3, can be socketed in easily on the staple 7 or by taking off its aperture and staple 7 couplings on it.Capsule pad 1 can be the sphere capsule pad that caves inward, so that it keeps contacting well with skin flesh.On the sphere that caves inward that sepage aperture 4 is distributed in skin flesh contacts, its aperture can be in 0.5～1 millimeter scope.In the illustrated example, the diameter of rounded sac pad 1 is 2 centimeters, and wall thickness is 0.5 centimeter, and the quantity of sepage aperture 4 is 5, uniform around staple hole 3.

Consult Fig. 1,3.Divide the liquid injection hole 6 on the fluid 2 to be positioned at the center, be used to insert syringe interface, aperture and needle tubing injection port coupling are 3 millimeters.

Consult Fig. 1,4.During use, to divide fluid 2 to be placed on the external fixer 9, make sphere corresponding skin flesh surface that each capsule pad 1 caves inward and insert one by one on each staple 7 by staple hole 3, place, nail road around just in time corresponding each staple 7 of the sepage aperture 4 that distributes around staple hole 3 on each capsule pad, medicinal liquids such as ethanol are injected by the liquid injection port 6 of minute fluid 2 by needle tubing, enter in each capsule pad 1 through flexible pipe 5, be penetrated into nail place, road by sepage aperture 4 then, carry out uninterruptedly or sterilization discontinuously.Keep contacting closely for making between capsule pad 1 and the skin flesh, prevent medicine liquid leakage, in the use can by locknut 8 with 1 locking of capsule pad on tight contact position.

Capsule pad 1 in this utility model, branch fluid 2 and flexible pipe 5 adopt materials making such as medical plastics.
