Description

Quasi-point pressure type hemostat

Technical Field

The utility model belongs to the technical field of hospital's nursing apparatus, concretely relates to kind point pressure formula haemostat.

Background

The prevalence of Chronic Kidney Disease (CKD) in our country is 10.8%, and CKD will eventually move towards life support by hemodialysis. Arteriovenous internal fistula is the life line of the arteriovenous internal fistula, and the safe maintenance of a vascular access is very important. At present, most hospitals in China still use unreadvocated elastic bandages to perform cerclage and compression hemostasis, one puncture point is arranged in each of the upper arm artery and vein, after a nurse pulls out the needle and fixes the puncture points, the patient needs to release the puncture points by himself or herself within 10-15 minutes, and the next puncture treatment is affected due to the fact that slippage, bleeding, subcutaneous hematoma and the like are prone to occurring in the process.

The existing elastic pressure pulse band is easy to roll, so that bleeding and hematoma are caused, chronic blood loss is caused by small or large amount of bleeding every dialysis for twelve times per month, and the life quality of a patient is not facilitated. Meanwhile, the ring-ligature mode of the elastic bandage is not favorable for stabilizing blood flow, and the occlusion of the internal arteriovenous fistula of the life line of a patient with hemodialysis is easily caused. The experts and guidelines of great authority do not provide a smooth application of elastic bandage for hemostasis, and finger pressure is recommended, but the finger pressure is actually difficult to be clinically applied.

Disclosure of Invention

Realize the utility model discloses the technical scheme that above-mentioned purpose adopted does:

the utility model provides a kind of point type haemostat, including the meshbelt, elastic gasket, the bolt, fixed block and time shape hook, elastic gasket's a surface is the plane, elastic gasket's another surface is bad arc, the meshbelt has tip A and tip B, elastic gasket's horizontal surface and a surface laminating of tip A are connected, tip A central authorities are equipped with the perforation, the fixed block is fixed in another of tip A on the surface, fixed block central authorities are equipped with the screw hole, it is fixed in one side of elastic gasket to return the shape hook, it is located tip A's the outside to return the shape hook, and return shape hook and meshbelt and be the linear distribution, tip B's an on the surface is equipped with the magic subsides, magic subsides and nut are fixed in respectively on.

The center of the horizontal surface of the elastic gasket is provided with a spherical crown-shaped recess which is just opposite to the through hole.

The fixed block is in a round table shape.

The inferior arc surface of the elastic gasket is sleeved with a silica gel elastic gasket.

The woven belt is provided with scales along the length direction, and the zero scale line of the scales is positioned at the end head of the woven belt on the end part B.

Compared with the prior art, the beneficial effects and advantages of the utility model reside in that:

1. this haemostat has set up elastic gasket, and elastic gasket has the arc surface, can fix the hemostasis gauze piece on the blood vessel puncture point, takes place to shift and blood loss, hematoma that lead to when preventing to press blood vessel.

2. This haemostat presses through the bolt and stanchs, has played the hemostatic effect of voltage, is similar to the finger point and presses, and the patient can carry out individualized regulation according to the thickness of arm moreover, and can one-hand operation, very convenient and practical.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The structure of the quasi-point-pressing hemostat provided by the utility model is as shown in figure 1, figure 2 and figure 3, comprising a mesh belt 1, an elastic gasket 2, a bolt 3 and a clip hook 5.

The mesh belt 1 is made of comfortable and skin-friendly non-elastic woven fabric belt, the width is about 3.2cm, the length is 29-35cm, and the mesh belt is divided into different types according to the length. As shown in fig. 5, the webbing 1 has an end portion a6 and an end portion B7, the end portion a6 is centrally provided with a through hole 8 which facilitates the passing of a bolt; the hook and loop fasteners 11 are arranged on one surface of the end part B7, and the two ends of the mesh belt are connected through the hook and loop fasteners to tie the mesh belt on the arm of the patient. The meshbelt 1 is equipped with scale 10 along its length direction, and the zero scale mark of scale 10 is located the end that meshbelt 1 is located on tip B7, through setting up the scale, makes things convenient for nurse and patient to fix a position, accomplishes the elasticity at every turn and is suitable.

As shown in fig. 4, one surface of the elastic pad 2 is a plane, a concave 9 in the shape of a spherical crown is arranged in the center of the horizontal surface of the elastic pad 2, the concave 9 is right opposite to the through hole 8, and the concave is arranged to limit the bolt, so as to prevent the pressure point of the bolt from deviating. The other surface of the elastic gasket 2 is in a poor arc shape, and a silica gel elastic gasket is sleeved on the poor arc surface of the elastic gasket 2 and used for protecting the skin.

The horizontal surface of the elastic gasket 2 is attached to one surface of the end part A6, the other surface of the end part A6 is provided with a truncated cone-shaped fixed block 12, the fixed block can be made of plastics and the like, and the fixed block is fixed on the woven belt in a bonding mode and the like. The center of the fixing block 12 is provided with a threaded hole 4, and the inner diameter of the threaded hole is 1.0 cm.

The clip hook 5 is fixed to one side of the elastic pad 2, the clip hook 5 is located outside the end a6, and the clip hook 5 and the webbing 1 are linearly arranged. The woven belt is bent under the action of the clip hook and then fixed into a ring through the magic tape.

The bolt 3 is cylindrical bolt, and the bolt 3 has three kinds, and the diameter of the bolt of three kinds is 1.0cm, and length is 1.5cm, 2.5cm and 3cm respectively, can change different bolts according to the difference of hemostasis intensity.

When hemostasis is needed, a gauze piece of 9 x 9cm is firstly folded into a gauze block of 2.5 x 3cm, skin and blood vessel puncture points are pressed, then the gauze block is pressed by the arc surface of the elastic gasket, then the braid is bent around the clip hook to form a ring, then the elastic gasket is fixed to form a ring by the magic tape, the elastic gasket is pressed on an arm by the braid, the gauze block is fixed to the place needing hemostasis on the arm, finally, the bolt is screwed on the fixed block, the bolt penetrates through a through hole in the braid and is pressed on a recess of the elastic gasket, the bolt rotates to generate force on the elastic gasket, the finger pressing is similar to, and the purpose of hemostasis is achieved. The bolt with proper length is selected according to the hemostasis and blood vessel condition of the patient.
