Detailed Description

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

An automatic inflatable pulse pressing device comprises an inflating device 1, an air pipe 2, a clip type bracket 3, an elastic part 4, an air bag 5 and an air release button 6.

The inflator 1 is internally provided with a pressure gauge. The inflator 1 is a conventional commercially available product, and for example, a Fujiwara/tengyuan brand electric inflator having functions of displaying pressure, adjusting pressure, and presetting pressure, which is a model of FUJ-DSIP01, may be used.

One end of the vent pipe 2 is connected with an inflation port of the inflation device 1, and the other end is communicated with the air bag 5.

The air bag 5 is fixedly arranged on the inner wall of the clamp type bracket 3 and forms a semicircular ring with the air bag 5.

Preferably, the air bag 5 is fixedly arranged on the inner wall of the clamp type support 3 through the magic tape 7, the air bag needs to be disinfected or damaged to some extent and needs to be replaced, the air bag is convenient to take and replace, and the magic tape can be fixed on the clamp type support and the air bag through glue.

The inflating device 1 acts, air is conveyed to the air bag 5 through the air pipe 2, and the air bag 5 expands, so that the stress surface is enlarged, and pressure is applied in a balanced mode.

The air bag 5 comprises a plurality of air bag sections 5 a; the adjacent air bag sections 5a are communicated with each other, and a gap with a narrow top and a wide bottom is formed between the adjacent air bag sections 5 a. The gaps between adjacent sections 5a are used to provide expansion spaces for the sections 5a to prevent the air bag 5 from wrinkling after inflation.

The clamp type bracket 3 comprises two bracket rods which are hinged with each other; the support rod comprises a clamping rod 3a for clamping and a holding rod 3b for changing the relative position of the clamping rod 3 a; clamping rod 3a and holding rod 3b fixed connection on the same cradling piece, and clamping rod 3a and holding rod 3b divide and locate the articulated department both sides of two cradling pieces.

The inner wall of each clamping rod 3a is concave arc-shaped, and a round cavity is defined by the adjacent clamping rods 3 a.

One end of the elastic element 4 is fixedly arranged on one holding rod 3b, and the other end is fixedly arranged on the other holding rod 3 b.

Preferably, the elastic member 4 is a compression spring, one end of the compression spring is welded inside one of the holding rods 3b, and the other end of the compression spring is welded inside the other holding rod 3 b.

As another preferred, the elastic component 4 is a torsion spring, the center of the torsion spring is provided with a rotating shaft at the hinged position of the two support rods in a penetrating manner, one end of the torsion spring is pressed against the inner side of one holding rod 3b, and the other end of the torsion spring is pressed against the inner side of the other holding rod 3 b.

The medical staff acts on the holding rods 3b to make the adjacent holding rods 3b approach each other, and the elastic member 4 is in a compressed state. By utilizing the lever principle, the adjacent clamping rods 3a are far away from each other at the moment and are in an opening state. The medical staff sleeves the clamping rod 3a on the arm of the staff needing venipuncture. Because the inner wall of the clamping rod 3a is concave arc-shaped, a round cavity is defined by the adjacent clamping rod 3a and the air bag 5. Therefore, when the medical staff loosens the holding rod 3b, the clamping rods 3a tend to approach each other under the action of the elastic piece 4, so that the arms are completely clamped, and the air bag 5 is in a to-be-inflated state, so that the comfort degree of the arms with various thicknesses is ensured; the inflating device 1 is started to deliver air to the air bag 5 through the air pipe 2, and when the air bag 5 is inflated, proper pressure is generated to exert a pulse pressing effect on the vein.

When the pulse pressing operation is finished, the deflation button 6 on the air bag 5 is pressed to release the air in the air bag 5, and the pressure is relieved.

When the device needs to be taken down, the medical staff acts on the holding rods 3b, so that the adjacent holding rods 3b are close to each other, and at the moment, the adjacent clamping rods 3a are far away from each other, so that the clamp-type support 3 is taken down from the arm.

The air bag 5 is provided with a deflation button 6.

In order to facilitate operation and deflation, the clip-type bracket 3 is fixedly provided with a pressure lever 8, as can be seen from fig. 1, the pressure lever 8 is specifically fixed on a holding rod 3b of the clip-type bracket 3, and one end of the pressure lever 8 is provided with a raised head 8 a; the deflation button 6 is fixed on the clip type support 3, generally at the critical position of the clamping rod 3a and the holding rod 3b of the clip type support 3, or at the position of the holding rod 3b near the critical position, which is beneficial to the compression bar 8 to push the deflation button 6 to deflate. 6 inside spring 6b, intake pipe 6d, gas vent 6c and the activity button 6a of setting up of gassing button, activity button 6a be provided with branch 6f and the sealed head 6e in inclined plane, the inside ventilation chamber 6h and the skew wall 6g that still is provided with of gassing button, branch 6f cup joints spring 6b and slides in ventilation chamber 6h, the sealed head 6e in inclined plane breaks away from the switch-on or sealed separation ventilation chamber 6h with the 6g clearance fit of skew wall, intake pipe 6d and gas vent 6c pass through ventilation chamber 6h and communicate. When the medical staff acts on the holding rod 3b to take off the pulse pressing device, the pressure rod raised head 8a on the clip-type bracket 3 is in sliding press fit with the movable button 6a, namely the pressure rod raised head 8a presses the movable button 6a, namely when the pressure rod raised head 8a is in sliding press fit with the movable button 6a, the movable button 6a abuts against the spring 6b to enable the air inlet pipe 6d and the air outlet 6c to be communicated for air exhaust. The raised head 8a of the pressure lever is a round surface, and the area of the raised head 8a of the pressure lever is larger than that of the movable button 6a, so that the pressure lever can return conveniently; the arrangement of the inclined sealing head 6e and the inclined wall 6g can ensure better sealing performance during blocking.

The present invention has been described in terms of embodiments, and a number of variations and improvements can be made without departing from the present principles. It should be noted that all the technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
