Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a lumbar puncture annular sliding positioning device, including the carriage 1 that is used for obeying the mouth style of calligraphy at back, carriage 1 includes the spacing frame 101 of square and by the inside impaling district 102 that is used for the operation of puncturing that forms of spacing frame 101. In order to improve the comfort of the back of the patient, an elastic cushion is sleeved on the limiting frame 101. The puncture area 102 may provide an accurate working area for the practitioner and may provide a constraint on the degree of bending of the patient's back, avoiding excessive bending of the back. The upper end and the lower end of the limit frame 101 are respectively connected with an upper limb body restraining frame 2 for stretching the shoulder and a lower limb body restraining frame 3 for stretching the waist and the back, and the upper limb body restraining frame 2 and the lower limb body restraining frame 3 are connected through a locking part 4. Realize the fixed of tensile and tensile back position of patient back on the whole, avoid because tired out the patient position transform that causes, the inaccurate problem of position of giving needle.

Specifically, the upper limb body-binding frame 2 comprises two arm rings 202 connected through an elastic band 201, and the front ends of the two arm rings 202 are connected through a detachable compression spring 203.

The lower limb restraining frame 3 comprises an elastic restraining frame 301, after a human body bends knees and bends waist, two inner side ends of the elastic restraining frame 301 respectively encircle the back of the waist and the front side wall of the ankle, a buffer rod 302 positioned at the inner side of the leg bend is connected between the elastic restraining frame 301, and two ends of a locking piece 4 are respectively connected between a compression spring 203 and the buffer rod 302.

When a human body is bent, the back is easy to bow, and the state of being relatively flat and convenient for applying a needle is difficult to keep. Therefore, the upper limb body-binding frame 2 further comprises an upper back arc plate 204, the elastic band 201 penetrates through the upper back arc plate 204, the upper part of the elastic binding frame 301 is provided with a lower waist arc plate 304, and the arc surfaces of the upper back arc plate 204 and the lower waist arc plate 304 are both convex towards one side of the human body. The axis of the back of the human body is contacted with one end of the arc-shaped bulge of the back arc-shaped plate 204 and the lower waist arc-shaped plate 304, so that the back is kept in a relatively flat state, and the needle application is convenient. Preferably, the back arc 204 and the lower waist arc 304 are constructed of a soft material for comfort.

In order to fix the upper arm and the ankle, two ankle rings 303 are disposed at the lower end of the elastic constraining frame 301 toward the inner side, and the arm ring 202 and the ankle ring 303 are made of elastic material and have a U-shaped opening structure.

If the legs of the patient are kept bent for a long time, the bent portions of the legs will feel tired, and even a bad smell may be generated in hot summer. Therefore, the buffer rod 302 is preferably a rubber rod, and the rubber rod is movably sleeved with a moisture absorption soft pad 305, so that the moisture absorption soft pad 305 can relieve leg fatigue and absorb sweat generated at the position of the leg bend. And the two ends of the rubber rod are respectively fixedly and detachably connected with the elastic restricting frame 301. One end of the buffer rod 302 is opened, so that the elastic restraint frame 301 is convenient to be sleeved on the lower limb, and then the other end of the buffer rod 302 is fixed on the elastic restraint frame 301.

For wearing, the locking member 4 includes a telescopic string 401 connected to the compression spring 203 and the buffer lever 302, respectively, and ends of the telescopic string 401 are detachably connected by a buckle 402. Wherein the telescopic cord 401 connected to the bumper beam 302 will pass through the gap between the legs and connect to the other telescopic cord 401.

As a preferred embodiment: when a patient needs to puncture the back, the patient lies on the side of the hardboard bed, the back is perpendicular to the bed surface, the legs are bent, the elastic restraint frame 301 is sleeved at the lower limb part from the lower part, the two inner side ends of the elastic restraint frame 301 respectively encircle the back of the waist and the front side wall of the ankle, and the ankle rings 303 are respectively clamped on the two ankles. The bumper beam 302 is then placed in the popliteal bend and secured at its free end to the elastic restraint frame 301.

The restraint frame 101 is then conformed to the back with the puncture area 102 aligned with the area of the patient requiring puncture. The upper limb body-binding frame 2 is worn from the back side of the back, the arm rings 202 are fitted around the arms, and the two arm rings 202 are connected from the chest part by the compression spring 203. Then the head is flexed forward and the chest, the compression spring 203 is engaged with the lock catch 402 at the end of the retractable cord 401 on the buffer rod 302, the patient does not need to apply force, and the trunk is naturally arched. Reduce the fatigue of the patient and improve the accuracy of the needle application.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
