Description

Technical Field

[0001] The invention relates to the technical field of prone position ventilation, and in particular to a body position device for prone position ventilation. Background Art

[0002] Prone position refers to the patient lying prone, with arms bent and placed on both sides of the head, legs straight; a soft pillow is placed under the chest, hips and ankles, and the head is tilted to one side. The prone position was first proposed by Bryan in the 1970s as a method to improve ventilation. It is a method for treating severe hypoxemia in patients with acute respiratory distress syndrome. At present, prone ventilation is increasingly used in clinical practice, especially for patients with dyspnea and difficult-to-correct hypoxemia. Studies have shown that prone ventilation can reduce mortality and improve patient oxygenation. For patients with mild to moderate hypoxia, adopting a conscious prone position can delay the deterioration of the disease. Awake prone ventilation can effectively treat patients with hypoxemic respiratory failure, and at the same time has a certain improvement effect on the oxygenation of patients with hypoxemia caused by new coronavirus infection.

[0003] The traditional method for prone ventilation is to let the patient lie prone on a soft pillow. However, this method is less comfortable, and the patient's body is squeezed on the soft pillow for a long time due to gravity, which will cause poor local blood circulation in the patient, causing numbness and other discomfort, and thus making it impossible for the patient to maintain prone position for ventilation for a long time. Summary of the invention

[0004] In view of the above problems existing in the prior art, the technical problem to be solved by the present invention is that the traditional prone ventilation method has low comfort level and will cause poor local blood circulation in patients for a long time, resulting in discomfort such as paralysis, which in turn makes it impossible for patients to maintain the prone position for ventilation for a long time.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a body position device for prone ventilation, comprising:

[0006] Base plate;

[0007] a bending member, both ends of which are slidably mounted on the bottom plate; and

[0008] The driving mechanism can drive the two ends of the bending piece to slide towards each other to adjust the curvature of the bending piece.

[0009] Preferably, the driving mechanism includes: a slider and a bidirectional screw; the two sliders are slidably installed on the base plate in the same direction; the bidirectional screw is rotatably installed on the base plate; the bidirectional screw is threadedly connected to the two sliders to drive the two sliders to slide towards each other; the two ends of the bending piece correspond one-to-one with the two sliders, and the ends of the bending piece are hinged to the corresponding sliders.

[0010] Preferably, it also includes an elastic belt; two of the driving mechanisms and the bending members are arranged parallel to each other; a plurality of elastic belts arranged parallel to each other are arranged between the two bending members, and the elastic belt and the bending members are arranged perpendicular to each other, and the two ends of the elastic belt are respectively fixedly mounted on the two bending members.

[0011] Preferably, it also includes a transmission mechanism; the transmission mechanism includes: a first bevel gear, a second bevel gear, a third bevel gear, a transmission shaft, a spline and a sleeve; a first bevel gear is coaxially fixed on each of the bidirectional screws; the second bevel gear is rotatably mounted on the base plate, and the second bevel gear is meshed with one of the first bevel gears; the transmission shaft is coaxially plugged into the second bevel gear through a spline sliding; the sleeve is rotatably mounted on the base plate, and the sleeve is coaxially arranged with the transmission shaft; a spline groove that cooperates with the spline is provided in the sleeve at one end close to the transmission shaft; the third bevel gear is coaxially fixedly mounted on the sleeve, and the third bevel gear is meshed with another of the first bevel gears.

[0012] Preferably, one end of the spline close to the sleeve is provided with a chamfer.

[0013] Preferably, it also includes a knob, which is installed at an end of the transmission shaft away from the sleeve.

[0014] Preferably, the driving mechanism further comprises a pushing member, and the two pushing members correspond to the two sliding blocks one by one; one end of the pushing member is hinged to the corresponding sliding block, and the other end of the pushing member is hinged to the middle part of the bending member.

[0015] Preferably, the pushing member is an elastic telescopic rod.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] 1. In the present invention, the patient's abdomen lies on the bending member, and the bending member supports the patient's abdomen, so as to perform prone ventilation; and when the patient's trunk and other parts experience discomfort such as paralysis, the driving mechanism is controlled to operate, and the driving mechanism drives the two ends of the bending member to slide towards each other, so as to adjust the arc of the bending member, help the patient to move the body, thereby promoting blood circulation in the patient's trunk and other parts, and thus can increase the time the patient is in prone ventilation.

[0018] 2. In the present invention, when the patient needs to change from a prone position to a lateral position, one of the two-way screws is rotated, and the two-way screw drives the two sliders to move away from each other, so that one of the bending parts is set in a straight line, and then the other two-way screw is rotated, and the two-way screw drives the other two sliders to move closer to each other, thereby driving the other bending part to bend and rise, thereby driving the multiple elastic bands to be set in an inclined state, and then the multiple elastic bands can drive the patient's body in the prone position to tilt, so as to complete the adjustment of the patient's body to the lateral position; for this reason, by adjusting the different bending degrees of the two bending parts, free switching between the prone position and the lateral position can be achieved.

[0019] 3. In the present invention, the elastic band is elastically deformed so that it can fit the patient's abdomen more conveniently, thereby improving the comfort level of the patient's abdomen; and through the setting of the elastic band, when the curvatures of the two bending parts change differently, the length of the elastic band can be adaptively elastically expanded and contracted, thereby avoiding the interference of the elastic band with the bending of the bending part.

[0020] 4. In the present invention, the sliders slide towards each other, and the sliders drive the two pushing members to rotate upward, so as to push the middle part of the bending member, thereby providing a supporting force for the middle part of the bending member to prevent the bending member from deforming downward to a large extent and failing to play a supporting role when the patient's abdomen is pressed downward; and because the middle part of the elastic band bends downward and deforms when the patient's abdomen abuts against multiple elastic bands, the elastic member applies a pulling force toward the other bending member to the bending member, driving the bending member to bend and deform inward. Therefore, by setting the pushing member, the bending member can be effectively prevented from bending and deforming inward. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] See also Figure 1-Figure 3 The embodiment of the present invention is as follows: a body positioning device for prone ventilation, comprising: a base plate 1, a bending member 2 and a driving mechanism 3; both ends of the bending member 2 are slidably mounted on the base plate 1; the driving mechanism 3 can drive the two ends of the bending member 2 to slide toward each other to adjust the curvature of the bending member 2.

[0030] During specific implementation, the patient's abdomen lies on the bending member 2, and the bending member 2 supports the patient's abdomen, so as to perform prone ventilation; and when the patient's trunk and other parts experience numbness or other discomfort, the driving mechanism 3 is controlled to operate, and the driving mechanism 3 drives the two ends of the bending member 2 to slide toward each other, so as to adjust the arc of the bending member 2, help the patient move the body, thereby promoting blood circulation in the patient's trunk and other parts, and thereby increasing the time the patient is in prone ventilation.

[0031] See also Figure 1-Figure 3 In other embodiments, the driving mechanism 3 includes: a slider 31 and a bidirectional screw 32; the two sliders 31 are slidably mounted on the bottom plate 1 in the same direction; the bidirectional screw 32 is rotatably mounted on the bottom plate 1; the bidirectional screw 32 is threadedly connected with the two sliders 31 to drive the two sliders 31 to slide in opposite directions; the two ends of the bending member 2 correspond to the two sliders 31 one by one, and the ends of the bending member 2 are hinged to the corresponding sliders 31. In specific implementation, the patient lies directly on the bending member 2 with his abdomen; the bidirectional screw 32 is rotated, and the bidirectional screw 32 drives the two sliders 31 to slide on the bottom plate 1, so as to adjust the curvature of the bending member 2.

[0032] See also Figure 1-Figure 3 In other embodiments, it also includes an elastic belt 4; two driving mechanisms 3 and bending members 2 are arranged parallel to each other; a plurality of elastic belts 4 arranged parallel to each other are arranged between the two bending members 2, and the elastic belt 4 and the bending members 2 are arranged perpendicular to each other, and the two ends of the elastic belt 4 are fixedly mounted on the two bending members 2 respectively.

[0033] During specific implementation, the width between the two bending parts 2 is greater than the width of the patient's body, so that the patient's abdomen lies directly on the multiple elastic bands 4; when the patient needs to change from a prone position to a lateral position, one of the two-way screws 32 is rotated, and the two-way screw 32 drives the two sliders 31 to move away from each other, so that one of the bending parts 2 is set in a straight line, and then the other two-way screw 32 is rotated, and the two-way screw 32 drives the other two sliders 31 to move closer to each other, thereby driving the other bending part 2 to bend and rise, thereby driving the multiple elastic bands 4 to be set in an inclined shape, and then the multiple elastic bands 4 can drive the patient in the prone position. The patient's body is tilted to complete the adjustment of the patient's body to the lateral position; for this purpose, by adjusting the different bending degrees of the two bending pieces 2, free switching between the prone position and the lateral position can be achieved; further, through the elastic deformation of the elastic band 4, it can be more convenient to fit the patient's abdomen, thereby improving the comfort level of the patient's abdomen; and through the setting of the elastic band 4, when the curvature of the two bending pieces 2 changes differently, the length of the elastic band 4 can be adaptively elastically expanded and contracted, thereby avoiding the interference of the elastic band 4 with the bending piece 2 when it is bent; specifically, the elastic band 4 can be an elastic band.

[0034] See also Figure 1-Figure 3In other embodiments, a transmission mechanism 5 is further included; the transmission mechanism 5 includes: a first bevel gear 51, a second bevel gear 52, a third bevel gear 53, a transmission shaft 54, a spline 55 and a sleeve 56; a first bevel gear 51 is coaxially fixed to each bidirectional screw 32; the second bevel gear 52 is rotatably mounted on the base plate 1, and the second bevel gear 52 is meshed with one of the first bevel gears 51; the transmission shaft 54 ​​is coaxially inserted into the second bevel gear 52 through a spline 55; the sleeve 56 is rotatably mounted on the base plate 1, and the sleeve 56 is coaxially mounted with the transmission shaft 54. Axis setting; a spline 55 groove cooperating with the spline 55 is provided at one end of the sleeve 56 close to the transmission shaft 54; further, a chamfer is provided at one end of the spline 55 close to the sleeve 56; so that the spline 55 can be more conveniently inserted into the spline 55 groove; further, it also includes a knob 57, which is installed at one end of the transmission shaft 54 ​​away from the sleeve 56; through the setting of the knob 57, the transmission shaft 54 ​​can be rotated more conveniently; the third bevel gear 53 is coaxially fixedly installed on the sleeve 56, and the third bevel gear 53 is meshed with another first bevel gear 51.

[0035] Specifically, when it is necessary to adjust the two bending members 2 at the same time, the transmission shaft 54 ​​is pushed toward the sleeve 56 to move, so that the transmission shaft 54 ​​slides on the second bevel gear 52 through the spline 55, and the spline 55 on the transmission shaft 54 ​​is inserted into the spline 55 groove in the sleeve 56; then the transmission shaft 54 ​​is rotated, and the transmission shaft 54 ​​drives the second bevel gear 52 to move through the spline 55, and the second bevel gear 52 drives one of the first bevel gears 51 meshing with it to rotate, and the first bevel gear 51 drives one of the coaxially fixed bidirectional screws 32 to rotate; at the same time, since the spline 55 is inserted into the spline 55 groove on the sleeve 56, the transmission shaft 54 ​​drives the sleeve 56 to rotate through the spline 55, the sleeve 56 drives the third bevel gear 53 to rotate, the third bevel gear 53 drives another first bevel gear 51 to rotate, and the other first bevel gear 51 drives another bidirectional screw 32 to rotate; in this way, the two bidirectional screws 32 can be driven to rotate synchronously, thereby realizing the synchronous adjustment of the two bending members 2.

[0036] When a bending part 2 needs to be adjusted, the transmission shaft 54 ​​is pulled to move in a direction away from the sleeve 56, so that the spline 55 on the transmission shaft 54 ​​is separated from the spline 55 groove on the sleeve 56; in this way, when the sleeve 56 and the transmission shaft 54 ​​are rotated, the corresponding bidirectional screw 32 can be driven to rotate respectively, thereby realizing the adjustment of a single bending part 2.

[0037] See also Figure 1-Figure 3In another embodiment, the driving mechanism 3 further includes a push member 33, and two push members 33 correspond to two sliders 31 one by one; one end of the push member 33 is hinged to the corresponding slider 31, and the other end of the push member 33 is hinged to the middle part of the bending member 2. In specific implementation, the sliders 31 slide in opposite directions, and the sliders 31 drive the two push members 33 to rotate upward, so as to push the middle part of the bending member 2, thereby providing support force for the middle part of the bending member 2 to prevent the bending member 2 from deforming downward to a large extent when the patient's abdomen is pressed downward, and thus failing to play a supporting role; and because the middle part of the elastic bands 4 bends downward and deforms when the patient's abdomen abuts against the multiple elastic bands 4, the elastic member will exert a pulling force on the bending member 2 toward the other bending member 2, driving the bending member 2 to bend and deform inward, so the setting of the push member 33 can effectively prevent the bending member 2 from bending and deforming inward. Furthermore, the pushing member 33 is an elastic telescopic rod; specifically, a spring is arranged inside the telescopic rod, so that the spring applies an outward elastic force to the inner rod, thereby driving the inner rod to slide toward the outside of the outer rod; through the setting of the elastic telescopic rod, the elastic telescopic member can not only push upward, but also have an elastic force to move in the vertical direction, so that the bending member 2 has a certain deformation ability in the vertical direction, so as to more conveniently fit the patient's abdomen.
