Problems solved by technology

[0004] However, because the patient needs to adjust the tightness of the tourniquet every half an hour (the tightness gradually decreases), generally 8-10 times, in the above-mentioned technical scheme, when the pressure airbag is deflated to realize the reduction of the pressure During the process, quantitative control of each exhaust volume cannot be carried out, so the pressure volume is not well controlled, which has adverse effects on patients

Embodiment 1

[0051] The tourniquet body 1 includes a photocatalyst sterilizing layer, a composite glue layer, and a waterproof protective layer successively from the side far away from the infant patient's skin to the side close to the patient's skin. 10 parts, 10 parts of carbon fiber particles, and 20 parts of gum arabic. The photocatalyst sterilization layer can be obtained by mixing the above raw materials in proportion. The composite glue layer is silane modified polyether glue. The waterproof protective layer made of EVA film can make the tourniquet body 1 have waterproof function, and the waterproof protective layer and the photocatalyst sterilizing layer are bonded through a composite adhesive layer.

[0052] Among them, the photocatalyst sterilization layer contains nano-titanium dioxide and nano-silicon dioxide, which can play the role of photocatalyst sterilization. Under the action of ultraviolet light, it has a strong catalytic degradation function: it can effectively degrade t...

Embodiment 2

[0054] The tourniquet body 1 is made of the following raw materials in parts by weight: 5 parts of polyacrylonitrile fiber, 10 parts of phosphate ester flame retardant, 5 parts of asbestos fiber, 5 parts of polyamide fiber, 5 parts of polyurethane fiber 3 parts of polylactic acid fiber, 3 parts of polypropylene fiber, 10 parts of strong fiber, 23 parts of polyvinyl chloride fiber, 8 parts of silk fiber, 5 parts of corn fiber and 5 parts of flax. Wherein the polyurethane fiber has a purity of 40%-50%, the polyamide fiber has a purity of 20%-30%, and the corn fiber and flax have a purity of 20%-30%. It has good elasticity, soft touch and simple formula, which can meet people's needs.

[0055] The tourniquet body 1 is made of the following raw materials in parts by weight: 120-150 parts of polyvinyl chloride resin, 120-150 parts of chlorinated polyvinyl chloride, 15-20 parts of polyhalophosphate flame retardant, ethylene - 8-10 parts of vinyl acetate copolymer, 12-15 parts of gr...

Abstract

The invention discloses a portable special tourniquet for internal fistula. The portable special tourniquet comprises a tourniquet body; a pressing airbag with a one-way valve is arranged on the tourniquet body and at the position of a puncture point of an arm of a patient, and is connected with a pressure gage; the one-way valve is connected with a pressing device for pressing the pressing airbag; the pressing airbag is positioned on one side surface, far away from the skin of a patient, of the tourniquet body; a soft cushion layer is detachably connected onto the tourniquet body and at a position of a puncture point of the arm of the patient; a placing hole for allowing a bleeding stopping cotton ball to be plugged in and fixed is arranged on the soft cushion layer; the pressing airbag is connected with a deflating airbag positioned outside the tourniquet body; the pressing airbag is communicated with the deflating airbag by an adjusting valve; a first seal cover is screwed on the deflating airbag; and the interior space of the deflating airbag is not larger than that of the pressing airbag by 1 / 8. The portable special tourniquet has the characteristics of providing quantitativepressure for the patient, adjusting pressure, and being stable and convenient.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a portable special tourniquet for internal fistula. Background technique [0002] Hemodialysis is still one of the best treatment methods for uremia patients. Arteriovenous fistula is the main access for hemodialysis, which can be said to be the "lifeline" of hemodialysis patients. The human body has extremely limited blood vessels that can be used as internal fistulas, and uremic patients are mostly in poor blood vessel conditions due to the lesions of the blood vessels themselves and the influence of blood drawing and intravenous infusion during long-term medical treatment. Therefore, how to use and correctly care for the internal fistula, prolong the service life of the internal fistula, ensure the smooth progress of dialysis, and improve dialysis treatment have become particularly important. [0003] The Chinese utility model patent with the notif...
