Examples

As shown in fig. 1, a venipuncture auxiliary device for elderly people, which is used for elderly patients to have difficulty in puncturing due to loose skin during venipuncture, and comprises: the puncture device comprises an elastic strip 1, a connecting rope 2, a tightening belt 3 and an inflation tube 4, wherein the elastic strip 1 is connected with the tightening belt 3 through the connecting rope 2, the two are respectively fixed at two sides of a puncture part to tighten the skin of the puncture part, meanwhile, the vein position can be fixed, the success rate of puncture is further improved, the tightening belt 3 is also communicated with the inflation tube 4, the inflation tube 4 is communicated with a sheet-shaped air cushion 32 at the inner side of the tightening belt 3 and inflates air therein, the comfort of a patient can be improved, an air cavity tube 42 communicated with the sheet-shaped air cushion 32 is arranged in the inflation tube 4, inflation is to push a spacer 46 positioned therein to move, and the air in the inflation tube 4 is pushed into the sheet-shaped air cushion 32, so that the sheet-shaped air cushion 32 is inflated and deflated.

The elastic band 1 is a long band with elasticity, and is tied at the far end of a puncture part when in use, which is equivalent to a tourniquet in the prior art, the elastic band 1 is connected with the tightening band 3 through the connecting rope 2, the connecting position of the connecting rope 2 and the elastic band 1 is positioned at the middle part of the elastic band 1, the connecting rope 2 is a non-elastic rope, which can not only avoid the loss of the elastic band 1 and the tightening band 3 which are used in a matching way, but also can be realized without a measuring tool as long as the connecting rope 2 is tightened, the optimal distance between the elastic band 1 and the tightening band 3 can be determined, if the distance between the elastic band 1 and the tightening band 2 is too far, the skin of the puncture part can not be tightened, and the operation of venipuncture of medical personnel can be influenced if the distance is too close, therefore, the distance between the elastic band 1 and the tightening band 3 is determined by tightening the connecting rope 2, which is more convenient to, and the use effect is better.

The tightening band 3 includes: magic tape 31, slice air cushion 32, clitellum 34, as shown in fig. 3, it is rectangular strip that the form is unfolded to clitellum 34, for the convenience of description become the medial surface with one of them face that contacts with patient's skin when using, another face is called the lateral surface, magic tape 31 comprises two parts that are close to each other and fix, two parts contact each other just can be fixed, these two parts are located the part that is close to two terminal surfaces on clitellum 34 medial surface, the lateral surface respectively, curl into a cylindrical back magic tape 31 two parts and can reciprocal anchorage, it plays the effect similar tourniquet to tie up area 3, with the trunk portion fastening of contact with it, make the part vein of treating the puncture be full, conveniently carry out venipuncture.

Further, the inner side surface of the ring belt 34 is also provided with a sheet-shaped air cushion 32, the sheet-shaped air cushion 32 is expanded after being inflated inside, and is in direct contact with a patient in the using process, the sheet-shaped air cushion 32 can be deformed due to pressure, the contact area between the sheet-shaped air cushion and the skin is further increased, the discomfort caused by the tightening of the tightening belt 3 to the patient is further relieved, and the tightening degree can be further controlled by controlling the gas flow of the gas filling pipe 4.

It should be noted that: be provided with a plurality of annular grooves 33 on the slice air cushion 32, annular groove 33 is parallel with the long limit of clitellum 34, is parallel to each other between the annular groove 33, can impress more lax skin in the annular groove 33 moreover, further tightens the skin of puncture position, owing to set up annular groove 33 in addition, has just also reduced the inside volume of slice air cushion 32 in other words, therefore inflation tube 4 that the volume is littleer just can satisfy the demand of filling and deflating, and it is more convenient to use.

As shown in fig. 1, an inflation tube 4 is further disposed on the outer side surface of the fastening belt 3, an air outlet end of the inflation tube 4 is communicated with the sheet-shaped air cushion 32 inside the fastening belt 3, the sheet-shaped air cushion 32 is inflated and deflated through the inflation tube 4, the structure of the inflation tube 4 is as shown in fig. 2, and the inflation tube 4 includes: an outer tube 41, an air chamber tube 42, a rotating rod 44, and a spacer 46, wherein the outer tube 41 is a hollow tube with one end sealed, the other end is an open end, the open end is communicated with the sheet-shaped air cushion 32 through a pipeline, the outer wall of the outer tube 41 is fixed on the ring belt 34, the air chamber tube 42 is located inside the outer tube 41, the air chamber tube 42 is also a round tube with one end open and the other end sealed, the outer diameter of the air chamber tube 42 is the same as the inner diameter of the outer tube 41 and is fixed on the inner wall of the outer appearance, the open end of the air chamber tube 42 and the open end of the outer appearance are located on the same plane, the spacer 46 dividing the air chamber tube 42 into two parts is arranged inside the air chamber tube 42, the rotating rod 44 is connected to the geometric center position of the spacer 46, the rotating rod 44 coincides with the axis of the outer tube 41, of course, the air chamber tube 42 and the closed end of the outer, the movement of the rotating rod 44 drives the spacer 46 to move, so that the air close to the open end part is pushed into the sheet-shaped air cushion 32 to inflate the sheet-shaped air cushion 32, the outer wall of the rotating rod 44 is provided with external threads, and oppositely, the through holes on the closed ends of the air cavity tube 42 and the outer tube 41, through which the rotating rod 44 passes, are provided with threads which are matched with the external threads of the rotating rod 44, so that the rotating rod 44 can move in the axial direction of the outer tube 41 only by rotating the rotating rod 44, the position of the spacer 46 is moved by rotating the rotating rod 44, the movement of the spacer 46 is better adjusted, the rotating rod 44 is rotated by a user, the end of the rotating rod 44, which is positioned outside the outer tube 41, is provided with a rotating block 45, and the rotating block 45 is provided with a groove to prevent slipping.

It should be noted that: a fixed plate 43 perpendicular to the axis is further arranged in the outer tube 41, and an internal thread matched with the external thread of the rotating rod 44 is arranged at the geometric center of the fixed plate 43, so that the rotating rod 44 is supported by the closed end of the air cavity tube 42 and the fixed plate 43 at the same time, and the rotating rod 44 can stably move.

The use method of the present invention is explained with reference to the attached figure 1:

firstly, an elastic strip 1 and a binding belt 3 are respectively fixed on two sides of a puncture position, namely two ends along the direction of a blood vessel, so that the puncture position is positioned between the elastic strip 1 and the binding belt 3, and the distance between the two ends is the distance for tightening a connecting rope 2, wherein the fixing of the elastic strip 1 only needs to tie the two ends of the elastic strip 1 together, and the fixing of the binding belt 3 is to tie a girdle 34 of the binding belt 3 on an arm and connect the two ends through a magic tape 31 on the binding belt 3;

next rotate the commentaries on classics piece 45 of gas tube 4, make bull stick 44 rotate thereupon, and then in pushing into slice air cushion 32 with the gas in the trachea pipe 42, aerify to slice air cushion 32 through aerifing the slice air cushion 32 and aerify and compress tightly the arm, because the utility model discloses an elastic band 1, tighten up area 3 and fasten, so all tightened the skin of puncture position both sides, can also stabilize venous position simultaneously, improve the success rate of carrying out the puncture to old patient.

In this embodiment, the magic tape is a mature prior art, and a user can flexibly choose the magic tape, so detailed description is omitted.
