Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0030] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] See Figure 1 and Figure 4 The digestive endoscopy examination position fixing mechanism protected by the present utility model includes a yoke arm member, a yoke leg member, and a main unit 4. The yoke arm member is cylindrical, and its side is formed with two arm slots that are recessed toward the interior of the yoke arm member and arranged opposite each other. The positions above the patient's arm joints are fixed to the two arm slots, and the inner walls of the arm slots are provided with airbag structures so that the size of the arm slots can be controllably changed with the change in the inflation volume. The yoke leg member includes two leg slots for fixing the positions above the patient's leg joints, respectively. The main unit 4 includes an air pump for controllably inflating the airbag structures in the arm slots.

[0032] The patient's arms are placed above their joints in the two arm slots of the yoke arm member. The air pump in the main body inflates the airbag structures on the inner walls of the two arm slots of the yoke arm member, causing the airbags to expand until they contact the patient's arms, thereby fixing the patient's upper arms. The yoke leg member fixes the patient's legs above their joints, thus achieving a fixed position for the patient. This makes the device easy to operate and adaptable to patients of different body shapes, making it highly practical.

[0033] In some embodiments, one end of the yoke arm member near the arm slot is configured to be concave toward the other end, thereby preventing the yoke arm member from contacting the patient's neck after fixing the patient's arm joints, causing the patient to have difficulty breathing.

[0034] In some embodiments, the yoke arm member is integrally constructed as an airbag structure, which helps to reduce the cost and weight of the yoke arm member, facilitates the movement of the yoke arm member, and improves practicality.

[0035] In some embodiments, the yoke leg member is constructed in a cylindrical shape and is fixedly connected to the yoke arm member. Two leg grooves are formed on the side surfaces of the yoke leg member, arranged opposite to each other and recessed toward the interior of the yoke leg member. The leg grooves are arranged flush with the arm grooves and have a larger cross-sectional area than the arm grooves. The inner wall of the leg groove is constructed as an airbag structure, which is inflated by an air pump so that the size of the leg grooves can be changed in a controllable manner.

[0036] In some embodiments, the leg member of the yoke is integrally constructed as an airbag structure and is internally connected to the arm member of the yoke to form an inflatable pillow 1. The inflatable pillow 1 is constructed as an integrated airbag structure and is detachably connected to an air pump. The inflatable pillow 1 has a simple overall structure and is inexpensive. It provides sufficient restraint for patients of average size and is highly practical.

[0037] In some embodiments, the leg yoke includes two leg slots facing the same direction and arranged side by side, and a connector 32. The outer walls of the two leg slots are connected to each other, and the side of the outer wall of any leg slot away from the other leg slot is a support surface 33 that supports the two leg slots. The connector 32 is connected to the open sides of the two leg slots. One end of the connector 32 is connected to the two interconnected leg slots, and the other end is connected to a matching portion 321. The matching portion 321 is detachably connected to the main unit 4 for positioning the leg yoke. One end of the connector 32 is fixedly connected to the open sides of the leg slots arranged side by side, and the other end is detachably connected to the main unit 4, constraining the patient's legs in the two leg slots respectively. The leg yoke of this structure has a strong restraining force, which helps to restrain the body position of patients with heavy weight.

[0038] In some embodiments, the main unit 4 further includes a power supply assembly and an attraction surface 411. The attraction surface 411 is a vertical side surface of the main unit 4. A first magnetic region 412 is provided on the attraction surface 411. The first magnetic region 412 is configured as a horizontal strip, electrically connected to the power supply assembly, and controllably generates a magnetic force. The mating portion 321 of the yoke leg member is an iron sheet that is magnetically attracted to any position of the first magnetic region 412. Connecting the main unit 4 and the yoke leg member through magnetic attraction facilitates operation and provides a tight connection. Because the first magnetic region 412 is large and the mating portion 321 of the yoke leg member can be adsorbed and connected to any position of the first magnetic region 412, fine-tuning of the relative position between the yoke leg member and the main unit 4 is possible, resulting in greater universality and practicality.

[0039] In some embodiments, the main unit 4 further includes a base 42, which includes a first rigid plate 421 disposed horizontally on the bed. The main unit 4 is fixedly supported on the first rigid plate 421, and the extension direction of the first rigid plate 421 is parallel to the suction surface 411 of the main unit 4. The first rigid plate 421 is pressed against the patient's hip joint, thereby fixing the position of the main unit 4 and facilitating the fixation of the patient's body position.

[0040] In some embodiments, the angle between the suction surface 411 and the extension direction of the connecting member 32 is any value between 30° and 60°, for example, it can be any value between 30°, 40°, 50° and 60°, to adapt to the patient's posture for gastrointestinal endoscopy.

[0041] In some embodiments, the base 42 further includes a second rigid plate 422 disposed horizontally on the bed. The second rigid plate 422 is connected to the first rigid plate 421, and the extension direction of the second rigid plate 422 is parallel to the extension direction of the connector 32. The second rigid plate 422 is provided with a second magnetic region 423 electrically connected to the power supply assembly. The second magnetic region 423 controllably generates a magnetic force for attracting and securing the support surface 33 of the leg yoke. The second magnetic region 423 on the second rigid plate 422 further secures the leg yoke, thereby helping to increase the restraining force on the patient's legs.

[0042] Example 1:

[0043] See Figures 1 to 5 The digestive endoscopy examination position fixing mechanism shown in a preferred embodiment of the present application includes an inflatable pillow 1, an arm pillow 2, a second leg yoke 3 and a main body 41. The inflatable pillow 1 can fix the patient's limb joints at the same time, the arm pillow 2 can fix the patient's arm joints, and the second leg yoke 3 can fix the patient's leg joints. The main body 41 is used in conjunction with the inflatable pillow 1, the arm pillow 2 and the second leg yoke 3. According to the patient's physical condition, multiple accessories are used in combination to achieve the fixation of the patient's position. The connection corners of each accessory are designed to be rounded to improve the safety of the patient.

[0044] See Figure 1The inflatable pillow 1 is constructed as a cylindrical airbag structure, including a first yoke arm member 11 and a first yoke leg member 12 that are interconnected. The first yoke arm member 11 has a first end and a second end opposite to the first end, and the first yoke leg member 12 is connected to the second end of the first yoke arm member 11. The first end close to the first yoke arm member 11 is the head end 13, and the end of the first yoke leg member 12 away from the first yoke arm member 11 is the hip end 14. The first yoke arm member 11 includes two first arm grooves 111 arranged opposite each other. The first arm groove 111 is close to the head end 13 and is recessed toward the interior of the inflatable pillow 1. Its inner wall is constructed in an arc shape with an arc of 300 degrees, which is convenient for fixing the patient's arm joints. The structure of the first yoke leg member 12 differs from that of the first yoke arm member 11 only in that the two first leg grooves 121 of the first yoke leg member 12 are larger than the first arm groove 111. The first leg slot 121 is flush with the first arm slot 111, and the distance between them matches the average human torso length. The head end 13 of the inflatable pillow 1 is configured in an arc shape that is concave toward the hip end 14, preventing it from contacting the patient's neck and affecting their breathing.

[0045] When the patient's position is fixed by the inflatable pillow 1, the inflatable pillow 1 is partially inflated so that the patient hugs the inflatable pillow 1, and the position above the patient's arm joints enters the two first arm slots 111 respectively, and the position above the patient's leg joints enters the two first leg slots 121 respectively. Continue to inflate the inflatable pillow 1 so that the cross-sectional area of the first arm slot 111 and the first leg slot 121 gradually shrinks as the air is inflated until the inner walls both contact the patient's arms or legs. At this time, the patient's position is fixed by the inflatable pillow 1, and the neck does not contact the inflatable pillow 1.

[0046] See Figure 1 、 Figure 2 and Figure 3 The structure of the arm pillow 2 differs from that of the inflatable pillow 1 only in that the arm pillow 2 is shorter and does not have the first leg groove 121, that is, the arm pillow 2 is only used as a second arm yoke and does not have the function of restraining the patient's legs. It can be used for examinations without restraining the patient's legs, or used in conjunction with the second leg yoke 3.

[0047] The second leg yoke 3 is generally rectangular and vertically arranged. The bottom surface of the second leg yoke 3 is flat and fixedly connected to a metal sheet, forming a support surface 33. Two second leg slots 31 are formed on the vertical side surfaces of the second leg yoke 3. These second leg slots 31 are rectangular with a rounded bottom, conveniently accommodating the patient's legs. A horizontal connector 32 extends between the two second leg slots 31, toward the opening of the second leg slot 31. The side surface of the connector 32, facing away from the two second leg slots 31, is inclined and fixedly connected to a mating portion 321. The mating portion 321 is a metal sheet and forms a 45° angle with the extension direction of the connector 32, aligning with the bending direction of the patient's legs when lying on their side. In this embodiment, the second leg yoke 3 is constructed of stainless steel. In other embodiments, shape-memory metal can also be used to enhance its universality. In some embodiments, the second leg slots 31 can also be equipped with air bags or latex pads to enhance the universality of the second leg yoke 3 and the comfort of the patient when using the second leg yoke 3.

[0048] See Figure 3 、 Figure 4 and Figure 5 The main unit 4 includes a body 41 and a base 42. The base 42 includes a first rigid plate 421 and a second rigid plate 422, which are arranged horizontally and connected to each other. The first rigid plate 421 and the second rigid plate 422 are both constructed of stainless steel and have a 45° angle between them. The main unit 41 has a cubic structure and is fixedly connected to the junction of the first rigid plate 421 and the second rigid plate 422.

[0049] The main body 41 includes an air pump, a power supply assembly, and a first magnetic zone 412. The air pump and power supply assembly are housed within the main body 41, and the air pump is removably connected to the inflatable pillow 1 and arm pillow 2 via a flexible hose, thereby inflating the inflatable pillow 1 and arm pillow 2. The vertical side of the main body 41 near the second rigid plate 422 serves as an attraction surface 411, which is parallel to the extension direction of the first rigid plate 421. The first magnetic zone 412 is an electromagnet structure, disposed on the attraction surface 411 of the main body 41, and its height matches the height of the mating portion 321 of the second leg yoke 3. The first magnetic zone 412 extends horizontally, extending through the entire attraction surface 411, forming a rectangular strip-like structure. The first magnetic zone 412 is electrically connected to the power supply assembly and, under the action of the power supply assembly, controllably generates a magnetic attraction force, thereby removably connecting to the mating portion 321 of the second leg yoke 3, thereby constraining the patient's leg joints above the second leg slot 31. Since the first magnetic zone 412 is relatively long and any position within the first magnetic zone 412 can attract the fitting portion 321 of the second leg yoke 3, it is convenient to fine-tune the position of the fitting portion 321 of the second leg yoke 3 relative to the body 41 so that the second leg yoke 3 can more tightly constrain the patient's legs.

[0050] The second rigid plate 422 is provided with a second magnetic region 423 electrically connected to the power supply assembly. When the mating portion 321 is connected to any position of the first magnetic region 412, the support surface 33 of the second leg yoke 3 is magnetically connected to the second magnetic region 423. This prevents the second leg yoke 3 from shifting due to unconscious struggles by heavy patients. The second magnetic region 423 completely covers the end of the second rigid plate 422 facing away from the first rigid plate 421. This prevents the support surface 33 of the second leg yoke 3 from being fully attracted to the second magnetic region 423 when the second leg yoke 3 and the body 41 simultaneously contact the patient's legs but are unable to make contact. The magnetic force generated by the second magnetic region 423 when energized repels the magnetic force generated by the first magnetic region 412, preventing the second rigid plate 422 from deforming toward the body 41 due to the magnetic force.

[0051] When using the second leg yoke 3 to constrain the patient's position, the base 42 is placed on the bed so that the first rigid plate 421 is perpendicular to the long side of the bed. The patient's hip joint presses against the first rigid plate 421, preventing the main body 41 from moving. The patient's legs are secured to the second rigid plate 422 via the second leg yoke 3, forming a stable triangular structure between the patient's legs, the first rigid plate 421, and the second rigid plate 422, thereby enhancing the restraining force on the patient's legs. The main body 41 is positioned to the right of the first rigid plate 421, thus accommodating the left side lying position commonly used during testing.

[0052] When the patient's body position to be fixed is one leg bent, this can be achieved by only restraining the position above the joint of one leg of the patient by the first leg yoke 12 or the second leg yoke 3, and the other leg can be left free, which will not cause adverse effects on the examination.

[0053] The beneficial effects of the present invention are that it can adapt to the needs of patients of different body shapes, different examination positions and different restraint strengths, and has high universality. The overall structure is simple and easy to operate, and it has high practicality.

[0054] Example 2:

[0055] The only difference between this embodiment and the first embodiment is that in this embodiment, the attracting surface 411 of the body 41 is perpendicular to the extending direction of the second rigid plate 422 , and the matching portion 321 is perpendicular to the extending direction of the connecting member 32 .

[0056] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
