The invention discloses a limb fixing device for a critical patient, belongs to the technical field of limb fixing, and aims to solve the problems that the contact area between a bandage and the arm of the patient is small, the constraining force is concentrated, pressure injury is easily formed due to long-time constraining, the pain of the patient is increased, local infection is possibly caused, and the illness state is aggravated. The hospital bed comprises a hospital bed body and two supporting plates fixed to one side of the hospital bed body, restraint straps are arranged on one sides of the supporting plates, a plurality of first pressure air bags are installed on one sides of the restraint straps, a plurality of second pressure air bags are further installed on one sides of the restraint straps, and the second pressure air bags and the first pressure air bags are arranged in a staggered mode. Alternate inflation and deflation of the first pressure air bag and the second pressure air bag are achieved through the two-way air pump, so that the pressed parts of the limbs are continuously alternated, local skin and soft tissue are prevented from being in a pressed state for a long time, local blood circulation is effectively improved, the problems of skin redness, pressure sores, limb ischemia and the like are solved, and the completeness of the limb tissue of a patient is protected.

The invention discloses a pushing and kneading auxiliary alignment device for enteroscopy, and relates to the technical field of medical instruments. The device comprises a supporting table, a plurality of uniformly distributed bearing plates are fixedly mounted at the top of the supporting table, two symmetrically distributed turnover bed plates are arranged at the top of the supporting table, the turnover bed plates are both placed at the tops of the bearing plates, mattresses are fixedly mounted at the tops of the bearing plates, and the mattresses are arranged at the bottoms of the bearing plates. A headrest is fixedly mounted at the top of each mattress, and a first turnover rod and a second turnover rod are arranged between the two bearing plates. The turnover motor drives the turnover bed plate on one side to turn over, so that the body of a patient lies on the turnover bed plate on the other side along with the turnover of the turnover bed plate and is converted into a left-side lying position or a right-side lying position from a horizontal lying position, and the vertical turnover bed plate is used as a support, so that the patient keeps the current side lying position, and the enteroscope entering is facilitated; an auxiliary effect is provided for changing the body position of the patient, and medical staff do not need to manually turn over the body of the patient.

The utility model relates to a high-precision metal bending part preparation die, which belongs to the technical field of bending dies and comprises a 45-degree bending die, a 80-degree bending die, a 90-degree bending die, a bending and shaping die and a pier-extruding and shaping die which are sequentially arranged from left to right, and the 45-degree bending die, the 80-degree bending die, the 90-degree bending die, the bending and shaping die and the pier-extruding and shaping die are sequentially arranged from left to right. The 45-degree bending die, the 80-degree bending die and the 90-degree bending die are used for sequentially carrying out 45-degree bending, 80-degree bending and 90-degree bending on raw materials, the bending and shaping die is used for shaping the bent raw materials, the upsetting and extruding shaping die is used for carrying out upsetting and extruding shaping on the bent and shaped raw materials, traditional two-time bending is changed into three-time bending, the bending and shaping process is simplified, and the production efficiency is improved. Compared with the prior art, the high-precision metal bending piece is formed by directly bending a metal material at 45-90 degrees in the prior art, large contusion generated on the surface of the metal material is avoided, a product is integrated through the bending and shaping die after bending, and finally, the product is subjected to upsetting and extruding through the upsetting and extruding shaping die, so that the high-precision metal bending piece is formed.
