Description

Technical Field

[0001] The utility model relates to a medical bed, in particular to a wound treatment bed which is convenient to operate, belonging to the technical field of medical beds. Background Art

[0002] The treatment of wounds and incisions in medical places is generally carried out on a professional wound treatment bed. A simple wound treatment bed is just a simple bed body. Since it cannot be adjusted, it cannot adapt to different medical staff to operate in a better posture. And because a lot of waste liquid will be generated in the process of wound treatment, it is not easy to handle these waste liquids splashing (sticking) on the bed body, and it is easy to cause secondary pollution. With the improvement of medical requirements, there have been various designs of professional debridement beds. There are also many professional debridement bed solutions disclosed in Chinese patent documents, such as CN215307827U (an emergency clinical cleaning and debridement suture operating table), which can also be used for debridement operations. A special diversion structure is set in this patent to handle waste liquid and avoid pollution. However, this bed body can only be operated in the lying position of the patient. In many cases, sitting debridement is more convenient than lying debridement in aspects such as wound cleaning and treatment, and the waste liquid pollution is easier to control; CN213911127U discloses a splash-proof debridement bed, which can make the patient in a comfortable position, and the dirt can directly flow into the dirt bucket, without polluting the treatment bed and the patient's wound, avoiding cross-infection and reducing the workload of medical staff. However, this bed can also only be operated in the lying position of the patient. Summary of the Invention

[0013] As shown in the attached drawings, a liftable variable-attitude debridement bed includes a rectangular base 1. Brake casters 2 are installed at the lower parts of the four corners of the rectangular base. An electric lift drive mechanism is installed on the base. In this embodiment, the electric lift drive mechanism is as follows: A front vertical rod 6 and a rear vertical rod 3 are respectively and fixedly connected to the base front and back. A front bent arm 7 is hinged on the front vertical rod 6, and a rear bent arm 4 is hinged on the rear vertical rod 3. The front bent arm and the rear bent arm are both two branches distributed left and right and parallel to each other, and are fixedly connected between the two branches, so the structure is stable. The front bent arm and the rear bent arm are in the same "7" shape and rotated counterclockwise by 90 degrees, and the hinge axis is close to the corner part of the "7" shape. The two ends of the drive link 17 are respectively hinged to the lower endpoints of the "7" shapes of the front bent arm and the rear bent arm. A front support arm 8 is hinged to the other endpoint of the "7" shape of the front bent arm, and a rear support arm 5 is hinged to the other endpoint of the "7" shape of the rear bent arm. The front support arm and the rear support arm are also two branches distributed left and right, and the two branches are respectively hinged to the corresponding side bent arms. The middle bed frame 9 is fixedly connected to both the front support arm and the rear support arm. The tail end of the electric push rod C18 is hinged to the base 1, and the action end is hinged to the drive link 17. The front bent arm, the drive link, the rear bent arm, and the middle bed frame form a parallelogram linkage lifting mechanism, and the lifting is driven by the electric push rod C, and the structure is very stable and reliable.

[0014] The middle bed frame 9 is fixedly connected to the lifting end of the lifting mechanism. A front bed frame 13 and a rear bed frame 14 are respectively hinged to the front and back of the middle bed frame 9. A middle groove 10 is fixedly arranged on the middle bed frame 9. A front groove 14 and a rear groove 12 are respectively fixedly arranged on the front bed frame and the rear bed frame. The rear end of the front groove is hermetically connected to the front end of the middle groove, and the rear end of the middle groove is hermetically connected to the front end of the rear groove by a flexible waterproof cloth. Both ends of the middle groove are open, the rear end of the front groove is open, and the front end of the rear groove is open. The tail end of the electric push rod A16 is hinged to the middle bed frame, and the movable end is hinged to the front bed frame 13. The tail end of the electric push rod B15 is hinged to the rear support arm, and the movable end is hinged to the rear bed frame 11. When the front bed frame, the middle bed frame, and the rear bed frame are in a horizontal state, the front groove, the middle groove, and the rear groove form a rectangular groove body. A liquid drainage port 19 is opened on the bottom of the rear groove. A plug can be configured on the liquid drainage port to prevent liquid from flowing out, and a drain pipe can be connected under the liquid drainage port. Pull out the plug and the liquid will drain from the drain pipe.

[0015] When using this debridement bed, the overall height is adjusted by the electric push rod C to facilitate the patient's access and the medical staff's operation. The electric push rods A and B are used to switch between the lying position and the sitting position to obtain a better operation posture.
