CN2235788Y - Convenient tourniquet - Google Patents

Abstract

The utility model relates to a convenient tourniquet, which is composed of a tourniquet buckle and a tourniquet eraser. The utility model is characterized in that the tourniquet buckle is composed of a round tube base, a piston matched with the base, and a spring arranged on the top of the piston. The round tube base has a one-way opening, two holes are arranged in vertical direction on the round tube base, and two pressure ridges are arranged on the round tube base in the major axis direction. The utility model has the advantages of simple structure, convenient operation, high speed, short tourniquet banding time, and discomfort (caused by picking and squeezing the skin of patients) avoidance. At the same time, because the tension of the tourniquet can be freely controlled, the utility model is favorable to the venipuncture. The utility model is a medical appliance with good serviceability.

Description

Dexterous tourniquet

This utility model relates to a kind of medical dexterous tourniquet.

The limbs shallow venipuncture is a operation of diagnosis and treatment the most basic, that use is very frequent, the limbs that need use rubber compression cord colligation patient when making the limbs shallow venipuncture make the full puncture procedure that is beneficial to of local vein blood vessel with the temporary interruption venous backflow.Tourniquet by nurse's colligation on patient's limbs, the stretching rubber is tied a knot after producing tension force by hand, owing in knotting, will keep the tension force of rubber compression cord, therefore knotting very effort, time-consuming, be awkward, the tensile size of rubber compression cord is also wayward, pulls crowded folder patient skin during knotting and causes pain and discomfort.

At above-mentioned existing problems, the purpose of this utility model is to provide a kind of dexterous easily and efficiently tourniquet.

This utility model utilizes a special hemostasis bracelet and wears open bore and the interior tourniquet rubber of fixing hole thereon, when tightening up the rubber compression cord two ends to the tension force that needs, with hands piston is unclamped, the spring of being located at piston tip outwards pushes, piston produces relative motion with the pedestal of hemostasis bracelet, make the rubber compression cord that is in fixing hole and the open bore produce a shearing force, play effect with the rubber compression cord knotting, in the time of need unclamping, push piston simultaneously with hand-held hemostasis bracelet, two holes between piston and the pedestal are got back on the relative position, shearing force disappears, rubber compression cord is released, deviates from from open bore thereafter, can dexterity take off.

This utility model is simple in structure, easy to operate and quick, shortened the colligation hemostatic time, avoided pullling squeezing and pressed from both sides pain and the discomfort that patient skin causes, simultaneously owing to the tension force of tourniquet can arbitrarily be controlled, after tested, the pressure that this tourniquet produces the human limb tissue is between 3-7 kPa, arterial pressure less than human body, venous pressure greater than human body, only block vein and interruption artery not, can make the human body superficial vein be in good full state, very favourable to venipuncture, thereby having improved operational quality, is a kind of suitability medical appliance preferably.

1-6 is described in detail this utility model below in conjunction with accompanying drawing.

This utility model is made of hemostasis bracelet 1 and tourniquet rubber 2, and hemostasis bracelet 1 is by a unidirectional opening, have two holes 3,4 and constitute with the garden pedestal tube 6 of two pressure ridges 5 with spring 8 that adaptive piston 7 of pedestal 6 and piston 7 tops are provided with along its long axis directions in vertical direction.Two holes 3,4 that pedestal 6 is provided with are respectively fixing hole and open bore.Be respectively equipped with a fixing hole 9 and open bore 10 corresponding to pedestal 6 on the piston 7.The skin of tourniquet 2 rubbers is a fibrous layer, is beneficial to colligation, and the upper end of its tourniquet 2 is to expand knot 11.Article two, form a groove 12 between the pressure ridge 5.
