Description

Technical Field

[0001] The utility model relates to the technical field of intubation assistance equipment, in particular to a prone ventilation hospital bed for tracheally intubated patients. Background Art

[0002] Tracheal intubation refers to the technique of inserting a special endotracheal tube through the glottis into the trachea, which can provide the best conditions for airway patency, ventilation and oxygen supply, airway suction, and prevention of aspiration.

[0003] Acute respiratory distress syndrome (ARDS) refers to a clinical syndrome mainly manifested by alveolar capillary injury after being attacked by pulmonary and extrapulmonary diseases such as severe infection, trauma, and shock. It belongs to the severe stage or type of acute lung injury. ARDS is a common disease that seriously threatens the lives of patients in the field of critical care medicine. In recent years, it has been found that prone ventilation for ARDS patients can effectively improve their oxygenation status. The mechanism lies in the redistribution of blood flow during lung tissue ventilation. Prone ventilation has good clinical effects, is economical and convenient. As one of the supportive treatment methods for acute respiratory distress syndrome (ARDS), prone ventilation treatment has gradually been widely recognized.

[0004] When traditional tracheally intubated patients are in the prone position for ventilation, they usually lie on an ordinary hospital bed. Because the patient has an intubation in the face or neck, it is necessary to avoid pressing on it. Currently, in clinical practice, only pillows are usually used to elevate the patient's head. Since the prone ventilation treatment time is relatively long each time, long-term prone treatment will cause problems such as patient discomfort, skin pressure sores, joint stiffness and spasm, which will affect the smooth progress of prone ventilation treatment.

[0005] Currently, in the prior art, for example, a prone position tool for tracheally intubated patients disclosed in a Chinese patent with the authorization announcement number CN219480657U can be adjusted to a prone hospital bed by leveling the backrest.

[0006] However, the above technical solution still has the following defects: the bed body is usually in the form of a flat plate, and the form of elevating the intubation is too single. When in the prone position, the face can only lie face down on the hospital bed, and it is difficult to adjust the head placement posture flexibly in a timely manner. For example, when it is necessary to turn the head left or right, etc., it is not only inconvenient for the layout and protection of the intubation, but also easy to cause compression damage to the face, affecting the smooth progress of the patient's treatment, and the use limitations are relatively large.

[0031] The following further elaborates on the specific embodiments of the present utility model with reference to the accompanying drawings.

[0032] As Figures 1 to 6 presented, some embodiments of the present utility model relate to a prone ventilation hospital bed for tracheal intubation patients, including:

[0033] A cushion support assembly, the cushion support assembly includes a chest pillow part 1 and a head pillow part 2. The chest pillow part 1 and the head pillow part 2 respectively pass through the first opening 4 and the second opening 5 of the main body 3 of the bed board. The head pillow part 2 is used to support the head and to turn the head to the prone orientation, and the chest pillow part 1 is used to support the chest to be level with the head;

[0034] A lifting assembly, the lifting assembly is used to drive the cushion support assembly to extend into or out of the main body 3 of the bed board.

[0035] In these embodiments, the lifting assembly drives the cushion support assembly to extend into or out of the bed board body 3, driving the chest cushion member 1 and the head cushion member 2 to extend into the first opening 4 and the second opening 5 respectively, so that the chest cushion member 1 and the head cushion member 2 are adjusted to appropriate height positions, thereby adjusting different cushion support heights according to the prone ventilation requirements of different patients, so as to better meet the flexible use of the cushion support, which is beneficial to improving the flexible adaptability of use. Through the cooperation of the chest cushion member 1 and the head cushion member 2, when cushioning the patient, the chest and head of the patient can be made as flat as possible, thereby avoiding the damage caused by excessive local compression, and also avoiding the stiffness damage caused by the neck or spine being in a reverse bending state for a long time. This not only effectively improves the comfort of prone ventilation, but also helps to ensure the safety of the treatment process. Through the setting of the head cushion member 2, it can not only stably support the patient's head, but also timely and flexibly turn the patient's head to the prone orientation according to the requirements of prone ventilation, that is, the patient can lie flat on the stomach, turn the head to the left or right at any angle, thereby avoiding the face being locally compressed at one position for a long time. This is not only convenient for the arrangement and protection of intubation, but also greatly reduces the work intensity of medical staff, and the operation and adjustment are more convenient and stable. It can also improve the comfort of the patient's face when lying prone, avoiding problems such as skin pressure sores and joint stiffness and spasm caused by long-term local compression, ensuring the smooth progress of prone ventilation treatment, effectively reducing the limitations of the use of prone ventilation treatment, and having stronger practicability.

[0036] It should be understood that in the present utility model, the prone orientation refers to the orientation of the patient's head relative to the bed board body 3 when the patient lies prone, including but not limited to the head lying flat on the stomach, the head turning to the left, the head turning to the right, etc. At present, during traditional prone ventilation, the patient's head is mostly in one of the states of lying flat on the stomach, turning to the left, or turning to the right and the angle is fixed. Through the flexible adjustment of the head cushion member 2 of the present utility model, the patient's head can be supported at any angular position, so as to better meet the different prone requirements of the patient, that is, to avoid the damage caused by local compression, timely adjust the patient's posture, and improve the prone comfort, which is more conducive to the smooth progress of prone ventilation treatment.

[0037] Furthermore, it should be understood that when the present utility model is in use, suitable protective pads such as mattresses, rubber pads, horseshoe pads, etc. can be arranged on the chest cushion member 1 and the head cushion member 2 according to the use requirements, so as to better reduce the prone compression, further improve the comfort of the patient's prone ventilation, and further avoid the occurrence of compression injuries.

[0038] In some embodiments of a prone ventilation hospital bed for tracheal intubation patients, the head cushion member 2 is a semi-closed annular plate with a relief opening, and the head cushion member 2 of the semi-closed annular plate is any one of a horseshoe shape, an arc shape, a frame shape, and a broken line shape.

[0039] In these embodiments, preferably, the headrest member 2 of the semi-closed annular plate is horseshoe-shaped. Through the through-hole in the middle of the headrest member 2, the patient's face can be stably placed. The relief opening of the horseshoe-shaped headrest member 2 makes it more convenient to arrange and protect the endotracheal tube. And when adjusting the prone orientation of the patient, there is enough relief space to ensure the movement of the endotracheal tube, effectively improving the safety and stability of use. During actual use, the size of the through-hole of the headrest member 2 can also be flexibly changed according to the prone needs, such as adding a cotton pad to reduce the size of the through-hole, so as to better fit the placement of the patient's face.

[0040] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, the chest rest member 1 is any one of an arc plate, a flat plate, and a concave-convex plate.

[0041] In these embodiments, preferably, the chest rest member 1 is an arc plate. Through the setting of the arc plate chest rest member 1, the patient's chest can be better padded, and at the same time, it can be flexibly padded according to the usage requirements, with higher usage flexibility.

[0042] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, the padding assembly further includes a carrier seat 6. The carrier seat 6 is slidably installed in the second opening 5. A channel 7 runs through the middle of the carrier seat 6, and the headrest member 2 can rotate at the top of the channel 7.

[0043] In these embodiments, through the cooperation of the carrier seat 6 and the headrest member 2, the patient's head can be padded more stably. The carrier seat 6 can provide auxiliary support and ensure the stability of the rotational adjustment of the headrest member 2. Through the coordinated cooperation of the two, the usage requirements of the patient's prone ventilation treatment are better met.

[0044] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, a sleeve 8 is fixedly connected to the lower surface of the headrest member 2. The sleeve 8 is rotatably installed on the inner side wall of the channel 7. A worm gear 9 is fixedly installed at the bottom end of the outer ring surface of the sleeve 8. A worm 10 runs through the inner side wall of the channel 7, and the worm 10 is meshed with the worm gear 9;

[0045] A limiting groove 11 is formed in the inner side wall of the channel 7, and a limiting ring 12 is formed on the outer ring surface of the sleeve 8. The limiting ring 12 is slidably installed in the limiting groove 11.

[0046] In these embodiments, a number of support vertical plates are formed at the top end of the sleeve 8, and the headrest member 2 is connected through the support vertical plates, which not only increases the clearance space but also helps improve stability. Rotating wheels are formed at both ends of the worm 10, and the worm 10 is rotatably installed on the bearing seat 6. Through the cooperation of the worm gear 9 and the worm 10, rotating the rotating wheel drives the worm 10 to rotate, and then drives the sleeve 8 to rotate in the channel 7 by driving the worm gear 9 to rotate, thereby driving the headrest member 2 to turn its orientation at the top end of the channel 7 (adjust the orientation of the clearance opening). It can not only ensure the firmness of the adjusted position through the self-locking effect of the worm gear 9 and the worm 10, but also perform adjustment quickly and stably, facilitating the arrangement and protection of the intubation tube, and making the use more flexible and convenient. Through the cooperation of the limiting groove 11 and the limiting ring 12, when the sleeve 8 rotates in the channel 7, the limiting ring 12 rotates in the limiting groove 11, which helps improve the firm and reliable support for the rotation of the sleeve 8.

[0047] In some embodiments of a prone ventilation hospital bed for tracheal intubation patients, the cushion support assembly further includes a fixed seat 13, and the fixed seat 13 is slidably installed in the first opening 4, and the chest cushion member 1 is fixedly installed at the top end of the fixed seat 13.

[0048] In these embodiments, the fixed seat 13 is a hollow frame seat. Through the cooperation of the fixed seat 13 and the chest cushion member 1, it helps improve the stability of the cushion support of the chest cushion member 1, and by sliding the fixed seat 13 in the first opening 4, the cushion support requirement of the chest cushion member 1 can be ensured while adjusting.

[0049] In some embodiments of a prone ventilation hospital bed for tracheal intubation patients, the lifting assembly includes a connecting frame 14, and the fixed seat 13 and the bearing seat 6 are respectively fixedly installed on both sides of the connecting frame 14;

[0050] Mounting plates 15 are respectively fixedly connected to the front and rear sides of the bed board body 3. A lifting screw rod 16 is rotatably installed on the front mounting plate 15. A lifting handwheel 17 is fixedly installed at the top end of the lifting screw rod 16. The lifting screw rod 16 passes through the connecting frame 14, and the outer ring surface of the lifting screw rod 16 is threadedly installed with the connecting frame 14. A guide rod 18 is fixedly installed on the rear mounting plate 15, and the guide rod 18 passes through the connecting frame 14.

[0051] In these embodiments, the connecting frame 14 is triangular. The fixed seat 13 is fixedly installed on one side of the connecting frame 14, and the bearing seat 6 is connected to the corresponding corner of this side of the connecting frame 14, which is beneficial to improving the stability of the connection. The lifting screw rod 16 is fixedly installed on the front mounting plate 15 through a bearing. When the lifting crank wheel 17 is shaken to drive the lifting screw rod 16 to rotate, the stability of the lifting screw rod 16 can be ensured. The lifting screw rod 16 passes through and is threadedly installed on the connecting frame 14, and the guide rod 18 passes through the connecting frame 14, and the connecting frame 14 can slide along the guide rod 18. By shaking the lifting crank wheel 17 to drive the connecting frame 14 to move, the guide rod 18 plays a good guiding and supporting role, and then the movement of the connecting frame 14 drives the chest pillow member 1 and the headrest member 2 to extend or retract, and the operation is more stable and efficient, which is beneficial to improving the work efficiency of medical staff.

[0052] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, it further includes:

[0053] An adjusting assembly for lifting the bed board body 3 and restricting the inclination of the bed board body 3 on the bed frame body 19.

[0054] In these embodiments, through the setting of the adjusting assembly, one end of the bed board body 3 located at the headrest member 2 can be lifted from the bed frame body 19 according to the usage requirements and fixed at an appropriate inclined position, so as to further adjust the comfort of the patient during prone ventilation and further meet the treatment requirements.

[0055] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, the adjusting assembly includes a baffle 20 formed at the left end of the bed frame body 19. The bed board body 3 is hinged to the baffle 20, and a fixed frame 21 is formed on the bed frame body 19, and the bed board body 3 can be clamped in the fixed frame 21.

[0056] In these embodiments, through the cooperation of the baffle 20 and the fixed frame 21, not only can the bed board body 3 be stably supported for lifting, but also the bed board body 3 can be firmly placed in the fixed frame 21, and it can be stably supported under different usage conditions, which is beneficial to improving the usage safety.

[0057] In some embodiments of a prone ventilation hospital bed for tracheally intubated patients, the adjusting assembly further includes two guiding inclined plates 22 and an adjusting screw rod 23. The two guiding inclined plates 22 are respectively fixedly installed on both sides of the lower surface of the bed board body 3. The adjusting screw rod 23 is rotatably installed on the bed frame body 19. The left end of the adjusting screw rod 23 is fixedly installed with an adjusting crank wheel 24. The outer ring surface of the adjusting screw rod 23 is threadedly installed with a reinforcing rod 25. The front and rear ends of the reinforcing rod 25 are respectively fixedly connected with guiding clamping seats 26, and the guiding inclined plates 22 are slidably installed in the corresponding guiding clamping seats 26.

[0058] In these embodiments, the guide inclined plate 22 is lower on the left and higher on the right (inclined toward the headrest 2), and a slide groove is formed in the middle of the guide seat 26. The slide groove ensures the stable sliding of the guide seat 26 and the guide inclined plate 22. As the guide seat 26 moves toward the guide inclined plate 22, the guide inclined plate 22 is lifted upward, and then the bed board body 3 is lifted to an inclined position. The left end of the adjustment screw 23 passes through the baffle 20 and is rotatably mounted on the baffle 20 through a bearing, and the right end of the adjustment screw 23 is rotatably mounted on a fixed plate located in the middle of the bed frame body 19. By shaking the adjustment wheel 24, the adjustment screw 23 is driven to rotate, and then the reinforcing rod 25 is driven to move along the adjustment screw 23, so that the bed board body 3 is lifted or lowered, and the adjustment is more flexible and convenient. By lifting the bed board body 3 (the lifting angle should not be too large), the degree of compression of the patient's body can be further reduced, thereby reducing compression damage, which is conducive to improving the comfort of the patient's prone ventilation treatment and greatly improving the flexibility and applicability of use.

[0059] When the utility model is used, after the patient is placed on the bed board body 3, the lifting wheel 17 is rotated to adjust the chest pillow 1 and the head pillow 2 to an appropriate height position (it can also be adjusted first and then the patient is placed), so that the patient's chest pillow 1 is supported on the patient's chest, and the head pillow 2 is supported on the patient's head, ensuring that the patient can stably perform prone ventilation treatment, thereby avoiding damage caused by excessive local compression, and also avoiding stiffness damage caused by the neck or spine being in a reverse bending state for a long time.

[0060] When the prone orientation of the patient's head needs to be adjusted, the rotating wheel drives the worm 10, and then drives the headrest 2 to rotate. It can be flexibly adjusted according to the patient's usage needs, and sufficient clearance space is more convenient for the arrangement and protection of the intubation, better meeting the usage needs, that is, avoiding injuries caused by local compression, adjusting the patient's posture in time, and improving the prone comfort, which is more conducive to the smooth progress of prone ventilation therapy.

[0061] If necessary, the adjustment wheel 24 can be rotated to raise the bed board body 3 to a proper angle to further reduce the degree of compression on the patient, thereby further improving the comfort of the patient's prone position ventilation and reducing compression injuries.
