Description
Technical Field
The utility model relates to the technical field of medical polypropylene splints, in particular to a medical polypropylene bone-setting splint.
Background
Bone-setting splints are specialized medical devices used to assist in the fixation of a fracture site. In the past, the auxiliary fixing object used by doctors is wood splints, and along with the technical progress, gypsum is gradually popular, but is gradually abandoned due to the defect of difficult disassembly, and polymer splints are commonly used at present. The medical bone-setting splint made of polypropylene is used as one of the high molecular splints, has the advantages of easy preparation and light weight, has certain hardness after molding, and can be fixed on a user through a binding belt, a magic tape or other structures without worrying about the problem of inconvenient disassembly and assembly, so that the medical bone-setting splint becomes the most outstanding one of the high molecular splints.
When the bone-setting splint is fixed on the user, it can cover a part of skin, and because the air permeability of the bone-setting splint made of medical polypropylene is low, the air permeability of the part of skin is bad when in use, especially when in use in summer, the user easily feels stuffy, and the problems of itching, red swelling and the like are generated. Therefore, a plurality of ventilation holes are formed on the bone setting splint made of medical polypropylene, such as the Chinese utility model of patent number 201610431832.8, which is a multifunctional splint for orthopedics clinical use, and comprises 3 clamping blocks, wherein the two sides are fixed clamping blocks, and a dosing clamping block is arranged between the fixed clamping blocks and the dosing clamping block, and the fixed clamping blocks and the dosing clamping block are connected with each other through elastic belts; the fixed clamping blocks positioned at the two ends are also provided with connecting buckles which can be mutually buckled, and the connecting buckles have the function of tightly binding and fixing the two ends of the clamping plate; the fixed clamping block is also provided with air holes. Because the clamping blocks are provided with air holes, the air permeability of the clamping plate can be improved.
It is necessary to provide the vent holes to promote the ventilation, but when the splash water is required to be contacted in special cases, such as bathing and going out to rain, people want the bone splint to resist water, i.e. the vent holes for ventilation can be temporarily closed.
The 201610431832.8 patent also proposes that the medicated clamp block is formed by a frame and a cover plate, the cover plate being located on the opposite side of the clamp plate from the recess, the cover plate being located on the side of the clamp plate that is not in contact with the skin when the clamp plate is mounted to the patient, so that the cover plate is mounted to the frame in an openable and closable manner. The structure can be used for ventilation except for medicine application, the cover plate is opened when ventilation is needed, and the cover plate is covered when water blocking is needed, but the long-time opening of the cover plate obviously influences the activities of the user.
The Chinese utility model with the patent number of 201519293839. X relates to an orthopaedics fixing splint which comprises a binding band, three fixing plates are arranged on the binding band, a medicine groove and a cover plate are arranged on the fixing plates, a bottom plate is arranged on the bottom surface of the medicine groove, a plurality of through holes are formed in the bottom plate, the cover plate comprises a first cover plate and a second cover plate, an elastic interlayer is arranged between the first cover plate and the second cover plate, a first bulge is arranged on the first cover plate, a second bulge is arranged on the second cover plate, and a first clamping groove and a second clamping groove are correspondingly formed in the inner side of the medicine groove. The structure can be used for ventilation besides medicine application, the cover plate is pulled out when ventilation is needed, and the cover plate is inserted when water blocking is needed.
When ventilation is needed, if the cover plate is completely pulled out, the storage position of the cover plate is easy to forget, even the cover plate is lost, and the cover plate is not easy to find out for use next time.
When the cover plate is required to be ventilated, if the cover plate is not completely drawn out, the cover plate can only tightly prop the first cover plate and the second cover plate on the medicine groove of the fixed plate through the elasticity of the elastic interlayer (the clamping effect of the first clamping groove and the second clamping groove is only when the cover plate completely covers the through hole, and the clamping effect of the first clamping groove and the second clamping groove is only matched with the first bulge and the second bulge to act, namely, when the cover plate is used for retaining water, on the one hand, the position of the cover plate cannot be well kept, on the other hand, when ventilation is carried out, the cover plate is also provided with a part of orthopedic clamping plates which are positioned outside the medicine groove and are used for fixing the position on a user, the suddenly increased part of clamping plates can not influence the activity of the user in a short time, and the state is kept obviously for a long time, so that the activity of the user is limited.
