The perineum is elastic, blood supply is rich, subcutaneous tissue is loose, pubis is arranged on the perineum, and ischium is arranged on two sides of the perineum. When the perineum is impacted by hard objects, the following situations can occur: i, bleeding and laceration on the surface of the vulvar tissue; II, skin is not split, and blood is led to loose tissue gaps to form hematoma of perineum when the skin is bleeding from a broken subcutaneous blood vessel.

The most common method for avoiding the expansion of hematoma is to compress or compress ice, but the position of the hematoma at the perineum is special, the compression or the ice compress is inconvenient, no special compression device for the hematoma at the perineum is available on the market, and the external force compression is usually carried out by using cotton pads, towels, sponge pads or ice compress bags by family members of patients at present. However, this compression method has the following disadvantages: i, the perineum of a human body is a curved surface, the compression force manually given is not uniform, the dressing can not be well attached to the surface of the perineum, excessive compression can occur in certain areas, under-compression can occur in certain areas, and the detumescence effect is affected; II, the compression operation given by people is difficult to be continuous and stable, and the detumescence effect is affected; and III, the compression is easy to tired by manpower, and the compression time cannot be ensured.

2. Has good adaptability to different patients:

2.1. is suitable for patients with different heights: because the heights of different patients are different, when different patients lie on the sickbed (the pillow is assumed to be placed at a fixed position close to the bed head), the distance between the perineum and the tailboard of the sickbed is also different, at the moment, the relative positions of the sleeve and the inserted link can be adjusted by selecting different axial strip hole sections (namely, moving the locking column into the target axial strip hole section), and then the distance between the pressing pad and the tailboard of the sickbed can be adjusted;

2.3 patients of different sexes: because the structures and the curvatures of the male and female perineum are different, the same flexible compression assembly is obviously not suitable for patients with different sexes, so the flexible compression assembly is designed into a structure style which is detachably connected with the front end of the elastic telescopic mechanism, and the flexible compression assembly can be customized according to the adaptability of patients with different sexes and even different body types, so that the flexible compression assembly can be replaced at any time when needed.

3. The patient can autonomously adjust the compression force in a small range: the patient lies on the sickbed on his back, separates the two legs and presses the perineum against the pressing pad, and the pressing force is provided by the spring B. The tighter the patient's perineum presses the pad, the more the elasticity of the spring B needs to be overcome, the greater the contraction degree of the spring B is, and the more the locking column moves towards the rear end of the sleeve along the axial strip hole section. The more loose the patient's perineum presses the pad, the less the spring force of the spring B needs to be overcome, the less the degree of shrinkage of the spring B, and the less the locking post moves in the direction of the rear end of the sleeve along the axial strip hole section.

Brief description of the utility model uses:

The corresponding axial slot segment 214 is selected according to the height of the target patient (i.e., the selection is made by moving the locking post 26 into the target axial slot segment 214) such that the distance of the pressure pad 33 relative to the tailboard 100 of the patient's bed is at a location that is compatible with the target patient (i.e., the location of the target patient's perineum is approximately after lying on his back on the patient's bed).

The corresponding connection table 111 is selected according to the body shape of the target patient (the rear end of the sleeve 21 is inserted into the target connection table 100 to realize the selection), so that the height of the pressure pad 33 relative to the bed surface of the sickbed is at a height matched with the target patient (namely, the approximate height of the perineum of the target patient from the bed surface of the sickbed after the target patient lies on the sickbed.

The corresponding flexible compression assembly is selected according to the sex of the target patient (the selection is realized by inserting the connecting rod 31 of the target flexible compression assembly into the connecting hole 221 of the inserted rod 22), so that the pressure pad 33 is more attached to the perineal physiological curve of the target patient.

After the patient lies on his back on the bed, the legs are separated and the perineum is pressed against the pad, at which time the compression force is provided by the spring B24. The patient can adjust the compression force automatically within a certain range according to the tolerance of the patient. The more tightly the patient's perineum presses the pressing pad 33, the more the elastic force of the spring B24 is overcome, the more the spring B24 is contracted, and the more the locking post 26 moves toward the rear end of the sleeve 21 along the axial strip hole segment 214. The more loosely the patient's perineum presses against the pad 33, the less the spring force of the spring B24 is required to overcome, the less the spring B24 contracts, and the less the locking post 26 moves in the direction of the rear end of the sleeve 21 along the axial bore segment 214.
