Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable and fixed-position gastrointestinal endoscopy bed. Background Technology

[0002] During gastroscopy and colonoscopy, the patient's position is generally determined based on the anatomical features of the intestines and stomach, which helps the endoscope reach the ideal examination location.

[0003] During a gastroscopy, the patient needs to lie on their left side, causing a slight leftward rotation at the junction of the stomach fundus and body, and allowing gravity to expose the stomach's interior. When the endoscope reaches the pylorus and needs to penetrate the duodenum, the operator must increase the force to advance the endoscope, allowing the lens to pass through the narrow pyloric sphincter and reach the duodenum. During this procedure, the patient's head is prone to tilting excessively backward due to the operator's force. If the head tilts excessively backward, the operator cannot find the point of leverage, leading to failed endoscope insertion and preventing the examination of any duodenal lesions. Furthermore, excessive head tilting can cause the patient's head to dislodge from the pillow, increasing the risk of cervical spine injury.

[0004] In addition, due to the numerous narrow and tortuous sections of the intestines, adopting a left lateral decubitus position with knees raised towards the chest facilitates colonoscopy insertion and minimizes invasiveness to the patient. During the procedure, for awake patients, discomfort caused by endoscope insertion and intestinal peristalsis, along with the insertion angle, can complicate the process, making it difficult for them to maintain a comfortable and prolonged position. For anesthetized patients, establishing a relatively standard position before the procedure helps ensure a smooth colonoscopy. Furthermore, if the patient experiences discomfort or resistance before anesthesia recovery, maintaining an ideal examination position will also be challenging.

[0005] Patent CN214909834U discloses a bedding system for gastroscopy departments, including an examination bed with a headrest at the top, a vertical backrest block on one side of the middle section, and a bending section and knee stop at the rear. This patent requires the patient to cooperate by bending their legs between the bending section and the knee stop to achieve leg restraint. However, this restraint design has significant drawbacks. Heavy patients have limited limb flexibility and cannot actively bend their legs to the designated position. On one hand, leg muscles bear the weight, making significant bending difficult; on the other hand, fat accumulation hinders normal leg joint movement. Even with assistance, accurately positioning the legs of a heavy patient between the bending section and the knee stop is difficult, requiring considerable effort, and improper force can cause patient discomfort, affecting the examination and failing to achieve the intended leg restraint effect. Utility Model Content

[0006] The purpose of this invention is to overcome at least one of the defects in the existing technology mentioned above and provide an adjustable and fixed-position gastrointestinal endoscopy bed. This bed adjusts the position of the leg stops by rotating a lead screw to drive a sliding block along a slide rail. It can be flexibly adjusted according to the patient's body shape and other actual conditions to meet the needs of different patients. Furthermore, the limiting blocks assist in fixing the patient's position, especially for heavy patients, those undergoing anesthesia, and those unable to cooperate with the required positioning during the examination, ensuring the stability of the patient's position during the gastrointestinal endoscopy and facilitating a smooth examination.

However, the scope of protection of the present invention is not limited to the following embodiments.

[0033] Example

[0034] This embodiment provides an adjustable and fixed-position gastrointestinal endoscopy bed; see the specific structure below. Figure 1-2 It includes a bed frame 1, a headrest 2, and a leg limiting assembly:

[0035] The head stop 2 is located on one side of the bed frame 1; the leg limiting assembly includes a slide rail 8 located on the other side of the bed frame 1, a sliding block 9 slidably connected to the slide rail 8, a lead screw 7 passing through the sliding block 9, a leg stop 5 located on the upper surface of the sliding block 9, and a limiting block 4 located on the side of the leg stop 5 facing the patient; medical staff can rotate the lead screw 7 to drive the sliding block 9 to slide on the slide rail 8; and the limiting block 4 can also be used to help fix the patient's position.

[0036] In this embodiment, the head stop 2 has an inwardly concave arc on the side facing the patient. The arc conforms to the physiological curve of the human head, increasing the comfort of the patient's head placement and preventing the patient's head from tilting excessively backward or even slipping off the edge of the bed during gastroscopy, which could lead to cervical spine injury.

[0037] In this embodiment, a pair of mounting seats 10 are provided at both ends of the slide rail 8, and the beginning and end ends of the lead screw 7 are respectively provided on the pair of mounting seats 10.

[0038] In this embodiment, a drive element 6 is provided at one end of the lead screw 7; the drive element 6 is a motor or a hand crank. The drive element provided at one end of the lead screw can be either a motor or a hand crank, and medical staff can choose the appropriate drive method according to the actual situation and needs.

[0039] In this embodiment, the leg block 5 is concave inward on the side opposite to the patient, and a reinforcing rib 3 is provided in the concave area.

[0040] In this embodiment, the limiting block 4 is located on the side of the leg block 5 away from the sliding block 9, so that there is a gap between the limiting block 4 and the sliding block 9 to facilitate the placement of the patient's foot.

[0041] In this embodiment, the limiting block 4 has a protrusion on the side facing the patient, and the end of the protrusion has an arc transition; the angle between the side of the protrusion near the sliding block 9 and the leg stop 5 is greater than the angle between the side of the protrusion away from the sliding block 9 and the leg stop 5.

[0042] In this embodiment, both the head block 2 and the limiting block 4 are provided with soft pads on the side that abuts against the patient, and the curved surface of the soft pads conforms to the human anatomical structure.

[0043] Working principle:

[0044] When a patient needs to undergo a gastroscopy and colonoscopy and lies on the examination bed, the patient's head is placed on the head block 2 on one side of the bed. The head block 2 has an inward concave arc on the side facing the patient, and the arc conforms to the physiological curve of the human head. At the same time, there is a soft pad on this side that conforms to the human anatomical structure, which can increase the comfort of the patient's head placement and effectively prevent the patient's head from tilting back excessively or even slipping off the edge of the bed during the gastroscopy procedure, thus preventing cervical spine injury.

[0045] The patient's legs are placed on the leg-limiting component on the other side of the bed. After adjusting the position of the leg stop 5, the patient's legs are placed on the leg stop 5. Simultaneously, a limiting block 4, located on the patient-facing side of the leg stop 5, assists in fixing the patient's position. The limiting block 4 is located on the side of the leg stop 5 away from the sliding block 9, with a gap between it and the sliding block 9 to facilitate foot placement. The patient-facing side of the limiting block 4 has a protrusion with a curved transition at the end. The angle between the protrusion near the sliding block 9 and the leg stop 5 is greater than the angle between the protrusion away from the sliding block 9 and the leg stop 5. This design allows for better fit to the patient's legs, and the protrusion helps to fix the knee area, enhancing patient comfort during the examination and achieving an ideal examination position, effectively limiting the position. Furthermore, a soft pad is provided on the side of the limiting block 4 that abuts against the patient to improve leg comfort.
