Description

Technical Field

[0001] The utility model relates to the technical field of anorectal post-operative analgesia, in particular to an anorectal post-operative analgesia device. Background Art

[0002] Anorectal disease refers to diseases that occur in the anus and large intestine, with the most common occurrence in the anorectal segment. The treatment of incision pain after anorectal surgery is an international problem. Most analgesics are systemic administration, such as traditional methods of oral and injectable analgesics, and intravenous and epidural analgesic pump analgesia. Oral analgesics are not effective, and injection of morphine-like analgesics requires controlled dosage and frequency. The use of analgesic pumps is cumbersome and often causes complications. Systemic administration of drugs cannot avoid the toxicity of drugs that affects the functions of important organs.

[0003] Existing devices generally place warm water or liquid medicine inside the bathtub. When the patient sits in the bathtub and contacts the liquid inside, the wound can be disinfected and pain relieved. In order to facilitate the patient to sit in the bathtub, the existing device has designed a lifting bathtub, which generally uses a screw or a telescopic motor to drive the bathtub to rise and fall. The patient only needs to sit on the chair and align his buttocks with the hole on the chair. After the bathtub rises, he can soak in the liquid for pain relief.

[0004] However, the existing bathtub and lifting platform are divided into fixed type and take-away type. One is to fix the bathtub directly on the lifting platform, which is inconvenient for cleaning the bathtub. The other is to put the bathtub directly on the lifting platform without fixing it. At this time, when the patient turns sideways or has other movements, the bathtub will move with the inclination of the body, so it is not stable enough. Therefore, a bathtub that can be fixed in position and convenient to take is designed to solve the above problems. Utility Model Content

[0029] Anorectal surgery is a clinical discipline that uses surgery as the main method to treat tumors, trauma and other diseases occurring in the anus and large intestine. Anorectal diseases most commonly occur in the anorectal segment. Postoperative care for anorectal surgery requires relieving the patient's pain, usually by placing warm water in the bathtub or soaking the buttocks with liquid medicine to relieve the patient's pain.

[0030] In the related art, the existing device uses a lifting platform to drive the bathtub to rise so that the patient's buttocks are immersed in the bathtub, thereby relieving the patient's pain. The bathtub and lifting platform of the existing device are generally fixed and removable. One is to fix the bathtub directly on the lifting platform. It is inconvenient to clean the bathtub. The other is to directly place the bathtub on the lifting platform without fixing it. At this time, when the patient turns sideways or has other movements, the bathtub will move with the tilt of the body, so it is not stable enough.

[0031] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an anorectal surgery postoperative analgesia device. When it is needed, first pull the pull rod 22 to drive the connecting rod 25 to rotate, thereby pulling the insertion rod 26 back to the inside of the lifting plate 12, and then put the bathtub 14 on the lifting plate 12, align the hole 21 with the position of the insertion rod 26, release the pull rod 22, the spring 24 pushes the protrusion 23 to move, and drives the pull rod 22 to move accordingly, and pushes the insertion rod 26 to insert into the inside of the hole 21 through the connecting rod 25 to limit the position of the bathtub 14. Finally, the patient only needs to sit on the seat 11, and there is a hole on the seat 11. At this time, the motor drives the screw 13 to rotate, and at the same time, the legs of the seat 11 limit the lifting plate 12, so when the screw 13 rotates, it drives the lifting plate 12 to rise until the patient's buttocks are completely immersed in the bathtub 14, relieving the patient's pain.

[0032] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figure 1-Figure 3 The embodiment of the present application provides an anorectal surgery postoperative analgesia device, comprising: a seat 11, a lifting plate 12 is arranged on the inner side of which, and a cavity is arranged inside the lifting plate 12; a screw 13 is arranged on the seat 11, and the bottom end passes through the lifting plate 12 and is threadedly connected to the lifting plate 12; a bathtub 14 is arranged on the top of the lifting plate 12; a positioning component 2 is arranged on the lifting plate 12, and the positioning component 2 includes: a hole body 21 opened at the bottom of the bathtub 14; one end of the pull rod 22 passes through the lifting plate 12 and is inserted into the cavity; a protrusion 23 is arranged at the top of one end of the pull rod 22; a spring 24 is arranged in the cavity of the lifting plate 12 and is connected to the protrusion 23; a connecting rod 25 is arranged at one end of the pull rod 22; the top of the insertion rod 26 passes through the inner wall of the cavity of the lifting plate 12 and is inserted into the hole body 21; the bottom of the vertical rod 27 passes through the inner wall of the insertion rod 26 and is connected to the inner wall of the cavity of the lifting plate 12.

[0034] When in use, first pull the pull rod 22 to drive the connecting rod 25 to rotate, so that the connecting rod 25 pulls the plug rod 26 back to the inside of the lifting plate 12, and at the same time, the protrusion 23 moves with the pull rod 22 and squeezes the spring 24, so that the spring 24 is compressed, and then the bathtub 14 is placed on the lifting plate 12, and the hole 21 is aligned with the plug rod 26, and then the pull rod 22 is released, and the spring 24 rebounds and pushes the protrusion 23, so that the pull rod 22 moves, and pushes the plug rod 26 into the hole 21 through the connecting rod 25, and the position of the bathtub 14 is restricted. Because the bathtub itself is filled with liquid and there is gravity, when the plug rod 26 is inserted into the hole 21, the plane movement of the bathtub 14 can be restricted, so the stability of the bathtub 14 can be ensured. Then the motor drives the screw 13 to rotate, because the legs of the seat 11 restrict the lifting plate 12, so when the screw 13 rotates, it drives the lifting plate 12 to rise until the patient's buttocks are soaked in the liquid medicine inside the bathtub 14. It can relieve the pain of the patient.

[0035] Specifically, the lifting plate 12 is set between the legs at the bottom of the seat 11 and limits the lifting plate 12.
