Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an adjustable special pillow for gastroenteroscopy. Background Art
[0002] Gastroenteroscopy mainly uses gastroscope and colonoscope to examine the esophagus, stomach, duodenum, colon, rectum, etc. through the mouth or anus. It can not only directly diagnose whether the gastrointestinal mucosa has inflammation, ulcers, erosions, polyps, tumors, etc., but also can take biopsies of gastrointestinal mucosal lesions for histopathological examination. With the continuous improvement and improvement of gastroenteroscopy technology, endoscopy can not only effectively improve the diagnosis rate of gastrointestinal diseases, but also perform minimally invasive treatments for gastrointestinal diseases such as polyp removal and endoscopic hemostasis. When patients have digestive tract symptoms such as nausea, vomiting, stomach pain, abdominal pain, diarrhea, hematemesis, bloody stools, and dysphagia, and suspected digestive tract lesions; postoperative follow-up; and minimally invasive treatment of gastrointestinal diseases can all be performed with gastroenteroscopy. Compared with other examinations, gastroenteroscopy can not only directly observe digestive tract mucosal lesions, but also take biopsies of suspected lesion tissues for pathological examination to assist in diagnosis. In addition, gastroenteroscopy can also perform minimally invasive treatments such as polyp removal, digestive tract hemostasis, and removal of foreign bodies.
[0003] Currently, patients usually use the side-lying position when undergoing gastrointestinal endoscopy. However, the patient's pillow is simply placed on the bed without effective fixation and is prone to sliding. The anesthesiologist has to support the jaw, which can easily cause aspiration, bringing inconvenience to clinical work. The operation time is prolonged and the height of the pillow cannot be adjusted according to the patient's body shape, which is not conducive to medical staff to perform gastroscopy intubation and subsequent examinations.

Dynamic connection, a sliding rod 8 is provided at the left end of the connecting block 3, a support plate 9 is slidably connected to the sliding rod 8, a support pad 10 is provided on the support plate 9, and an arc-shaped groove with an opening facing upward is opened on the support pad 10, a toothed belt 11 in the left and right directions is provided in the sliding rod 8, a pulley 12 is fixed on the left transmission shaft 5, the right side of the toothed belt 11 is inserted into the left transmission groove 4 and cooperates with the pulley 12, a plurality of teeth 13 evenly distributed along the left and right directions are provided on the support plate 9, and the teeth 13 are inserted into the tooth grooves of the toothed belt 11.
[0016] In order to facilitate fixing the support tube 1 on the bed board, two positioning plates 14 facing each other up and down are provided on the left side of the lower end of the support tube 1. A fastening bolt 15 is threadedly connected to the lower positioning plate 14. The upper end of the fastening bolt 15 passes through the positioning plate 14 and is rotatably connected to a clamping plate 16.
[0017] In order to facilitate the movement of the roller 6 along with the support rod 2 , a moving groove 17 with an opening facing right is opened on the right side of the support cylinder 1 , and the roller 6 extends out of the moving groove 17 .
[0018] In order to facilitate the rotation of the toothed belt 11, a rectangular clearance groove 18 is opened on the sliding rod 8. The clearance groove 18 opens upward and the right end is connected to the outside. The toothed belt 11 is located in the clearance groove 18, and the left side of the toothed belt 11 is rotatably connected to the sliding rod 8 via the front-to-rear axial connecting shaft 19.
[0019] In order to facilitate the control of the rotation of the transmission shaft 5, a worm gear 20 is coaxially provided at the front end of the transmission shaft 5. Two left and right axial worms 21 are rotatably connected in the connecting block 3, and the two worms 21 are respectively engaged with the worm gear 20 on their corresponding sides.
[0020] In order to facilitate the control of the rotation of the worm 21, the interior of the right worm 21 is a hollow structure that passes through from left to right. Polygonal grooves 22 are respectively provided at the opposite ends of the two worms 21. The two polygonal grooves 22 are connected to each other. A polygonal block 23 is slidably connected in the right multi-deformable groove. A rotating column 24 is provided at the right end of the polygonal block 23. The right end of the rotating column 24 passes through the connecting block 3 and is provided with a cushion.
[0021] In order to facilitate the use of the device, a soft pad 25 is provided in the groove.
[0022] When the utility model is in use, the rotating column 24 and the connecting block 3 are simply connected by plugging and unplugging, so the rotating column 24 can rotate and slide left and right. When in use, the clamping plate 16 is moved upward by rotating the fastening bolt 15, and the support tube 1 is clamped on the bed board at the head of the bed through the positioning of the clamping plate 16 and the upper side. At this time, the support plate 9 is in contact with the upper surface of the bed board, and the patient lies on the support pad 10, and the ears are placed on the soft pad 25 in the groove;
[0023] If the height of the support pad 10 needs to be adjusted, it is only necessary to rotate the cushion clockwise. The cushion is driven by the rotating column 24 and the multi-deformation block to drive the worm 21 on the right side to rotate. The worm 21 on the right side drives the worm wheel 20 on the corresponding side to rotate, and the transmission shaft 5 on the right side rotates. The transmission shaft 5 on the right side wraps the drawstring 7 around its outer side. The drawstring 7 drives the roller 6 to roll and slide upward. The roller 6 drives the support rod 2 to move upward. The support rod 2 drives the support pad 10 to move upward via the connecting block 3. If the height needs to be lowered, it is only necessary to rotate the cushion in the opposite direction.
[0024] If it is necessary to adjust the position of the support pad 10 in the left and right directions, it is only necessary to move the soft pad to the left. The soft pad drives the rotating column 24 and the polygonal block 23 to be inserted into the polygonal groove 22 on the left. At this time, the soft pad is rotated to drive the worm 21 on the left to rotate. The worm 21 on the left drives the worm wheel 20 on the left to rotate. The worm wheel 20 on the left drives the toothed belt 11 to rotate through the transmission shaft 5 and the pulley 12 on its corresponding side. The toothed belt 11 drives the support plate 9 to slide to the left through the teeth 13, and the direction is to rotate the soft pad. Through the above steps, the support pad 10 slides to the right, and due to the one-way self-locking transmission of the worm wheel 20 and the worm 21, the position of the support pad 10 will not change after adjustment.
[0025] The utility model has an ingenious structure and is easy to use. By arranging a support tube, a positioning plate and a splint, the support cushion can be fixed on the bed board, thus avoiding the situation that the pillow moves when the patient is intubated with a gastric tube. The patient's head is stably supported when the gastric tube is intubated, which is convenient for medical staff to perform operations and examinations on the patient and for the patient to maintain unobstructed breathing during colonoscopy. At the same time, a support frame, a connecting block, a sliding rod and a support plate are provided, which are convenient for medical staff to raise the patient's head to a suitable position according to needs or according to the different body shapes of the patient. At the same time, the pillow can also be moved left and right, which is convenient for the patient to use. When in use, a rotating handle, a rotating column, a worm wheel and a worm are provided. Only the rotating handle needs to be rotated to realize adjustment in the up, down, left and right directions. No additional limiting operation is required, which is beneficial to the operation and use of medical staff. The utility model has a simple structure, is easy to operate, has a novel conception and is highly practical.
