Further perfection, the sponge pads are fixedly connected to the inner side surfaces of the left side and the right side of the splint, so that the friction force between the splint and the skin can be increased while a patient is prevented from being injured by the splint, and the product is better fixed.

Further perfection, splint head all inclines to the inboard at 45 degrees for the splint head is located the protection silica gel stick extension part of silica gel stick lower extreme when not using.

Further perfect, pressure piece lower extreme fixedly connected with is located the inside spacing of connecting tube, and the upper end of first spring is located spacing intraductal, and its purpose is for touchhing pressure piece that first spring can be accurate, avoids the spring to rock the positional deviation who causes.

The utility model discloses profitable effect is: the utility model discloses in be equipped with the unit and be mmHg or cmH 2O's manometer, the better patient's condition of judging of medical personnel of being convenient for is equipped with the silica gel stick, can effectively alleviate patient's pain when measuring when the painful position of the person of being convenient for to touch is equipped with splint, and the fixed position of being convenient for need not push down with the hand always, convenient record. Be equipped with spacing pipe, be convenient for ensure that first spring can not squint, be equipped with the foam-rubber cushion, be convenient for increase frictional force, prevent to press from both sides simultaneously and hinder the patient.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to FIGS. 1-4: a pressure testing device for measuring the swelling degree of soft tissues comprises a pressure gauge 1, wherein the pressure gauge 1 is spirally connected with a connecting pipe 2; the bottom of the pressure gauge 1 is fixedly connected with a pressure block 3 positioned on the inner side of the connecting pipe 2; a stop block 5 is arranged on the inner wall of the connecting pipe 2; a silica gel rod 6 is arranged inside the connecting pipe 2, and the lower end of the silica gel rod 6 is semicircular; the upper end face of the silica gel rod 6 is fixedly connected with a first spring 4, and a gap is formed between the first spring 4 and the pressure block 3.

Referring to FIG. 2: the bottom of the connecting pipe 2 is fixedly connected with an outward expanding block 10, and the inner side of the outward expanding block is provided with a first groove 8.

Referring to fig. 3 and 4: a shell 11 connected to the outer expanding block 10 is arranged at the bottom of the outer side of the first groove 8, and second grooves 17 are formed in the left side and the right side of the shell 11; the bottom of the second groove 17 is fixedly connected with a fixed block 13, and the surfaces of the fixed blocks 13 on the two sides are respectively and independently welded with one end of a spring 12; the other end of the spring 12 is connected with a clamping plate 7 in the second groove 17 in a welding mode.

Referring to FIG. 3: the inner side surfaces of the left side and the right side of the splint 7 are fixedly connected with spongy cushions 21. The heads of the splints 7 are all inclined at 45 degrees to the inside.
