Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, in particular to a multi-position back-patting ventilation bed. Background Art

[0002] Mechanical ventilation is an effective means to improve the patient's ventilation function, but in the past, traditional supine ventilation was mostly used. The pressure in the drooping lung area on the back is higher, which can easily cause compressive atelectasis, thus affecting the ventilation effect. Therefore, it is necessary to improve the mechanical ventilation posture.

[0003] Secondly, respiratory diseases can easily increase the amount of sputum and the viscosity of sputum. If it is not discharged in time, it may cause sputum accumulation and blockage, thereby inducing respiratory failure, and even threatening the patient's life in severe cases. Therefore, it is crucial to strengthen the sputum discharge treatment for patients with respiratory diseases and improve the patient's ventilation function. However, although the traditional manual back-knocking sputum discharge method can promote the discharge of sputum to a certain extent, disabled patients need multiple people to assist in sitting and standing, and then medical staff will knock on the back to expectorate. The steps are cumbersome, and the sputum discharge of patients with infectious diseases such as COVID-19 is easy to cause infection to medical staff, so it needs to be improved.

[0004] Therefore, it is necessary to develop a ventilated bed that can change the patient's position in multiple positions and can pat the back while maintaining the position. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-position back-patting ventilation bed, which can turn the patient's upper body into a prone position by rotating the lying board and moving the moving platform up and down, so that the medical staff does not need to make the change manually, so it is more convenient. Putting the patient in the prone position can reduce the pressure on the sagging lung area of ​​the back. In addition, due to structures such as side panels and head placement parts, the body position can be maintained during the back-patting, so there is no need for medical staff to provide manual assistance, so it is more convenient and reduces the infection of medical staff.

DETAILED DESCRIPTION

[0058] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.

[0059] like Figure 1-Figure 12 As shown, a multi-position back-patting ventilation bed includes a base 1, a movable platform 3, a lying board 4 and a back-patting member 5, wherein a plurality of wheels 11 are arranged at the bottom of the base 1, and the wheels 11 are used to drive the base 1 to move, and then drive the whole to move, so that the whole can be moved in front of the patient and drive the patient to move.

[0060] Secondly, the moving platform 3 is arranged on the base 1 and can move up and down, and the lying board 4 is used for the patient to lie prone and moves with the moving platform 3, and the lying board 4 can be rotatably arranged on the moving platform 3, and side boards 41 are arranged on both sides of the lying board 4. Moreover, the two side boards 41 are located under the armpits of the patient, so as to lift the patient as the lying board 4 moves up and rotates, and then the patient is turned into a prone state with the upper body, and the two side boards 41 are clamped on both sides of the patient's body to prevent the patient from moving out of the side of the lying board 4.

[0061] The prone position here is semi-prone position, that is, the person faces downward but has a certain inclination. In simple terms, the lying board 4 is not completely horizontal, but has a certain angle, which is a bit like holding a baby and patting the back. And this angle is also for better patting the back.

[0062] Meanwhile, a head placement piece 42 is disposed on the top of the lying board 4, and the head placement piece 42 is used to place the head and has an opening 421 for exposing the face.

[0063] Moreover, there are two back-patting pieces 5 which are respectively arranged on two side panels 41, and the back-patting piece 5 includes two back-patting parts, and the back-patting parts are movably arranged on the side panels 41, so that back-patting at different positions of the back can be achieved through the four back-patting parts, and the two back-patting parts of the same back-patting piece 5 can be rotated with each other and thus can be folded and placed.

[0064] The material used for the back is sound insulation material or a polyester fiber sound-absorbing panel interlayer to reduce noise.

[0065] Therefore, in actual use, the whole body is first moved to the patient by the wheels 11, and then the patient is placed on the lying board 4, and the upper body is fixed by the side panels 41 and the head placement member 42. At this time, the patient is turned into a prone position with the upper body as the lying board 4 moves and rotates. Therefore, it is more convenient without the need for manual transformation by medical staff, and putting the patient in a prone position can reduce the pressure on the sagging lung area of ​​the back.

[0066] Secondly, when a back pat is needed, the two back pats are unfolded, that is, the two back pats are separated and flattened, so that the patient has four back pats on his back, thereby achieving back patting at different positions of the back, thereby making the back patting effect better, and when the back pat is not needed, the two back pats are folded and are equivalent to an extension of the side panel 41, thereby not affecting other uses.

[0067] Therefore, due to the structures such as the side panels 41 and the head placement piece 42, the body position can be maintained during the back patting, so there is no need for manual assistance from medical staff, which is more convenient and reduces infection for medical staff. In addition, the back patting at different positions of the back can be achieved through the four back patting pieces, and the two back patting pieces of the same back patting piece 5 can be rotated with each other and then folded and placed, so that they serve as the side panels 41 when not in use.

[0068] The base 1 includes a bottom plate 12 , and wheels 11 are arranged at the bottom of the bottom plate 12 , and the moving platform 3 is driven by a cylinder 2 102 .

[0069] like Figure 1As shown, a mask 6 is provided on one side of the head placement piece 42, and the mask 6 is connected to pipe 1 and pipe 2, wherein pipe 1 is connected to an oxygen supply device, and the oxygen supply device is used to provide high-flow oxygen to the mask 6, and pipe 2 is connected to a sputum collection device, and the sputum collection device is used to collect body sputum for the mask 6.

[0070] Therefore, in actual use, the mask 6 is provided to prevent sputum or droplets from spreading in the air when the patient coughs, and the oxygen supply device can provide the patient with a high flow of oxygen, and cooperate with the sputum collection device, so that sputum can be collected in time while patting the back.

[0071] The sputum collection device and the oxygen supply device can adopt existing technology and be directly matched with the mask 6.

[0072] Moreover, a one-way valve 8 is built into pipeline 2, and the one-way valve 8 is used to prevent sputum from flowing back. A switch valve 9 is provided between the one-way valve 8 and the patient in pipeline 2, and the flow of pipeline 2 is controlled by the switch valve 9, thereby avoiding the transportation of oxygen to the sputum collection device when sputum is not collected.

[0073] like Fig.12 As shown, the one-way valve 8 includes at least three flaps 81, and the flaps 81 are elastic and can be reset. At the same time, the switch valve 9 includes a rotating member 91 and a baffle 92, and the pipeline is divided into two sections, and the two sections are connected by the rotating member 91. Secondly, the baffle 92 is rotatably arranged between the two sections and blocks the opening of the section close to the patient, and the inner wall of the rotating member 91 and the outer wall of the baffle 92 are tooth-engaged, so the baffle 92 can be driven to rotate by rotating the rotating member 91.

[0074] Therefore, in actual use, the baffle 92 is driven to rotate by rotating the rotating member 91, so that the baffle 92 is no longer blocked, and the sputum collection device is activated to generate negative pressure or an outward adsorption force. At this time, the flap 81 is unfolded downward due to the different forces on both sides, thereby collecting sputum. After the sputum is collected, the flap 81 is reset without the force of the sputum collection device to prevent sputum from flowing back.

[0075] Then, the rotating member 91 is rotated to drive the blocking piece 92 to rotate, and the blocking piece 92 is used to block, thereby preventing oxygen from being transported to the sputum collection device when the sputum is not collected.

[0076] like Figure 1 As shown, the base 1 has a main control panel and a speaker built in, and the main control panel is electrically connected to the oximeter 20 and the speaker. Therefore, in actual use, when the oximeter 20 detects that the blood oxygen is too high or too low, it will transmit information to the main control panel and then control the speaker to issue a reminder.

[0077] The main control board is a circuit board used to control various functions and movements of the bed. At the same time, the base 1 is provided with a groove 16 for placing the blood oximeter 20 when not in use, and the blood oximeter 20 is connected to the main control board through wires.

[0078] Moreover, when the mask 6 and the oximeter 20 are present at the same time, when the oximeter 20 detects that the blood oxygen is too high, it will transmit information to the main control board to control the oxygen supply device to stop supplying gas.

[0079] like Figure 1 As shown, a strap structure may be provided to limit the position of the patient. The specific structure is: first, a strap 71 is provided at the bottom of the lying board 4, and the strap 71 is V-shaped, and a strap 72 is provided on the side of the side panel 41 close to the patient's head, and both ends of the strap 71 pass through the lower end of the patient's thigh and are connected to the straps 72 on the two side panels 41, thereby preventing the patient from falling off the lying board 4 and driving the patient to move with the movement of the lying board 4.

[0080] Therefore, in actual use, some patients may slide down because their bodies are paralyzed and uncontrollable. At this time, the arrangement of the strap 1 71 and the strap 2 72 can prevent the patient from falling off the lying board 4 and drive the patient to move with the lying board 4.

[0081] like Figure 1 , Fig.10 , Fig.11 and Fig.13 As shown, in addition to limiting the upper body, the lower body also needs to be limited and moved. At this time, there are two structures. The first one also includes a knee assembly 2, which is used to clamp the knee and limit the position of the patient's legs, and the knee assembly 2 includes two clamps 25, and the two clamps 25 are respectively arranged on both sides of the base 1.

[0082] Moreover, the structure of the clamping member 25 is that a placement groove 251 is provided on the side close to the patient's knee, so that the knee can be placed and clamped.

[0083] At the same time, for patients with difficulty in sputum discharge, the body position needs to be changed, so a rotatable lifting plate 30 is provided on both sides of the base 1, and the lifting plate 30 is located on one side of the knee and in contact with the knee, and the knee and calf are lifted upward by rotating the lifting plate 30.

[0084] Therefore, in actual use, the lifting plate 30 is rotated to lift the knees and calves upward, so that the whole person can continue to tilt downward, that is, the patient is in a prone position or even in a position with the head lowered and the waist raised, so that sputum can flow out more easily.

[0085] At the same time, the lifting plate 30 adopts the form of a turbine worm gear, wherein lifting plates 30 are arranged at both ends of the worm gear, and the turbine is connected to the motor, and an arc groove or a clamping member 25 may be arranged on the side of the lifting plate 30 that contacts the knee, so that the lifting plate 30 can fit the knee and the calf more closely, and an assisting plate 301 is arranged on the side of the lifting plate 30 to increase the contact area with the knee and the calf, wherein the assisting plate 301 can be arranged to be a detachable disassembly structure such as a block and a groove, so that different assisting plates 301 can be used for different people.

[0086] like Fig.10 and Fig.11 As shown, when the knee assembly 2 is provided, the specific structure of the clamping member 25 is as follows: first, the two clamping members 25 are connected by a connecting rod 21, and the clamping member 25 is detachably provided on the connecting rod 21, and the clamping member 25 can be moved up and down, that is, a telescopic rod is provided between the connecting rod 21 and the base 1.

[0087] Therefore, in actual use, the clamping member 25 can be replaced because it is detachably arranged on the connecting rod 21. Moreover, the arrangement of the telescopic rod can adjust the position of the clamping member 25 corresponding to different patients.

[0088] At the same time, the specific structure of the telescopic rod is as follows: first, the telescopic rod includes an upper rod 22 and a lower rod 23, wherein the top of the upper rod 22 is connected to the connecting rod 21 and is movably arranged on the lower rod 23, and the lower rod 23 is connected to the base 1, and the position of the clamping member 25 is adjusted by moving the upper rod 22.

[0089] The limiting between the upper rod 22 and the lower rod 23 is achieved by positioning beads, that is, a positioning column is provided on the inner wall of the lower rod 23, and a plurality of positioning grooves are opened on the outer wall of the upper rod 22 along the moving direction of the upper rod 22. The positioning column is limited in the positioning groove, and the positioning column is moved to different positioning grooves for movement.

[0090] Secondly, the structure of the positioning column is that a steel ball is set at the opening of the shell, and a spring is set between the steel ball and the shell, and the spring is used to retract and reset the steel ball. Fig.11 .

[0091] like Fig.10 and Fig.11 As shown, a moving rod 24 is provided between the clamping member 25 and the connecting rod 21, and the moving rod 24 is movably provided on the connecting rod 21 and drives the clamping member 25 to extend or retract, so as to be suitable for different patients. A positioning column structure or a gear and rack structure can also be adopted between the moving rod 24 and the clamping member 25, so as to achieve synchronous extension or retraction of both sides.

[0092] At the same time, the structure of the gear and rack: first, a gear is arranged inside the connecting rod 21, and the moving rods 24 on both sides are provided with racks on the side close to the gear, and the racks and gears are meshed with each other, so when pulling outward or retracting inward, they can be driven synchronously.

[0093] Moreover, a placement groove 251 is provided on the side of the clamping member 25 close to the patient's knee, and the clamping member 25 is rotatably disposed on the connecting rod 21 , so that the placement groove 251 and the patient's knee can be better fitted by rotating the clamping member 25 .

[0094] The rotating structure of the clamping member 25 is as follows: first, a mounting portion 252 is provided on one side of the clamping member 25 close to the connecting rod 21 , and the mounting portion 252 is rotatably disposed on the connecting rod 21 and a positioning bead structure can be used between the mounting portion 252 and the connecting rod 21 .

[0095] like Figure 2-Figure 6 As shown, the feeling of patting the back can be brought about by moving forward and backward, or by vibration. When it is brought about by moving forward and backward, that is, the patting member 5 includes a moving block 51, and the moving block 51 is a cylinder or the moving block 51 is moved and arranged on the side plate 41 under the action of the cylinder three, and the two patting back parts are respectively patting back 1 52 and patting back 2 53, and the patting back 1 52 and the patting back 2 53 are rotated with each other so as to be folded and placed, and the patting back 1 52 is rotatably arranged on the moving block 51 and moves under the drive of the moving block 51 so as to pat the patient's back.

[0096] The moving block 51 adopts a pneumatic structure because some patients who use devices such as cardiac pacemakers need to stay away from electromagnetic energy. Therefore, pneumatic back patting can keep electromagnetic energy away from the human body, thereby setting the circuit below. The air source can be a high-pressure air source, that is, an air compressor.

[0097] Secondly, when it is caused by the front-back vibration, that is, a plurality of back-patting blocks 54 are built in the back-patting device, and the directions in which two adjacent back-patting blocks 54 exert force outward are opposite. Such a design allows the back to be patted in two directions.

[0098] Meanwhile, the back-slapping block 54 has an elastic mold 541 built therein, and the elastic mold 541 divides the inner space of the back-slapping block 54 into a first cavity 542 and a second cavity 543, and the side wall of the back-slapping block 54 is provided with a side hole 1 544 and a side hole 2 545 connected to the second cavity 543. Moreover, a push block 547 is arranged on the elastic mold 541, and a spring 546 is arranged between the push block 547 and the inner wall of the first cavity 542, and a one-way component is connected to the second cavity 545, and the one-way component is used to control the flow of the second cavity 545.

[0099] The elastic mold 541 is mainly used for sealing and is movable, which is somewhat similar to the structure inside a syringe, that is, movable and sealing.

[0100] Therefore, in actual use, air is introduced into the second cavity 543 through the side hole 1 544, thereby driving the movement of the elastic mold 541 and the push block 547 and compressing the spring 546, and the side hole 2 545 is allowed to flow through the one-way component to discharge the gas in the second cavity 543, and the push block 547 moves under the action of the spring 546 and collides with the back-patting block 54 close to the patient to pat the patient's back.

[0101] The push block 547 adopts a structure that matches the pneumatic starter and the spring 546 because some patients who use devices such as cardiac pacemakers need to stay away from electromagnetic energy. Therefore, the pneumatic back patting can keep electromagnetic energy away from the human body, thereby setting the circuit downward. The air source can be a high-pressure air source, that is, an air compressor, and multiple back patting blocks 54 are connected.

[0102] At the same time, the structure of the one-way component is as follows: first, the one-way component includes an air pipe 55, and the air pipe 55 includes a main pipe 551 and a side pipe 552, wherein the main pipe 551 is provided with an air inlet and a connecting port 554 at both ends, and the connecting port 554 is used to connect with the side hole 544, and secondly, the side pipe 552 is provided with an exhaust port 555, and the main pipe 551 is provided with a blocking block 556 between the side pipe 552 and the air inlet, and the diameter of the connecting port 554 is larger than the diameter of the air inlet.

[0103] Therefore, in actual use, when air is taken in by side hole 1 544, air is also taken in by the air inlet at the same time, so that the block 556 is located at the connection point between the main pipe 551 and the side pipe 552, so that the exhaust port 555 is not connected with the connecting port 554. Secondly, when no air is taken in, due to the high air pressure inside chamber 2 543, the other air in chamber 2 543 flows toward the air pipe 55 and drives the block 556 to move toward the air inlet, so that the exhaust port 555 is connected with the connecting port 554, thereby discharging the gas in chamber 2 543.

[0104] Secondly, the back-patting block 54 can be provided with a limit block on the side in contact with the spring 546 to limit the movement of the spring 546 .

[0105] like Figure 2-Figure 3 As shown, in order to ensure that the second back-patting part 53 is located in the same straight line as the first back-patting part 52 after being flipped, a limiting structure or electronic induction can be used.

[0106] The limiting structure is as follows: first, a limiting structure is set between the back-patting 1 52 and the back-patting 2 53, and the limiting structure is used to limit the rotation range of the back-patting 2 53, thereby ensuring that the back-patting 2 53 is located in the same straight line with the back-patting 1 52 after being turned over.

[0107] At the same time, the specific structure of the limiting structure is: first, the back part 52 is provided with a connecting block 521, and the back part 53 is provided with a connecting block 531, and the connecting block 521 and the connecting block 531 are connected by an axis and can rotate.

[0108] Furthermore, a clamping block 524 is disposed on the first connecting block 521 , and a clamping slot 533 is provided on the second connecting block 531 corresponding to the clamping block 524 , so that the clamping block 524 and the clamping slot 533 are matched with each other to limit the position.

[0109] Secondly, the electronic sensing structure is as follows: first, a sensing point is set at the bottom of the back pat 1 52, and a sensor is set at the position corresponding to the sensing point at the top of the back pat 2 53. Therefore, in actual use, the sensor detects whether the sensing point is located at the top to ensure that the back pat 2 53 is located in the same straight line with the back pat 1 52 after flipping. If it is not sensed, a warning can be issued.

[0110] Then the rotating structure of the back-patting part 52 is as follows: first, the back-patting part 52 is provided with a connecting block 3 522, and the connecting block 3 522 is connected to the moving block 51 through an axis, so as to be rotatable.

[0111] At the same time, the rotation limiting structure of the back part 53 is as follows: first, a limiting block 534 is set at the bottom of the back part 53, and a limiting groove 525 is opened on the back part 52 corresponding to the limiting block 534, and the limiting block 534 and the limiting groove 525 are adapted to each other to limit the position.

[0112] Moreover, a second limiting block 532 is disposed on the side of the second back pat 53, and a second limiting groove 511 is formed on the moving block 51 corresponding to the second limiting block 532, so that the second limiting block 532 and the second limiting groove 511 are matched to limit the position.

[0113] like Figure 7 As shown, two cylinders 101 are arranged between the lying plate 4 and the moving platform 3, and the two cylinders 101 are driven synchronously and in reverse, and a rotation connection is adopted between the top of the cylinder 101 and the lying plate 4, so as to avoid interference between the rotation of the lying plate 4 and the up and down driving of the cylinder 101.

[0114] like Figure 8 and Fig. 9 As shown, the side plate 41 is movably arranged on one side of the lying plate 4, and a movable plate 43 is arranged between the side plate 41 and the back-patting member 5, and the movable plate 43 is movably arranged on the side plate 41, so that the side plate 41 and the movable plate 43 can be moved to adapt to different patients.

[0115] The movable structure of the side plate 41 is as follows: first, a connecting portion 411 is provided on one side of the side plate 4 close to the lying plate 4 , and the connecting portion 411 is movably provided on one side of the lying plate 4 and a positioning bead structure can be adopted between the connecting portion 4 and the lying plate 4 .

[0116] Furthermore, the movement of the side plate 41 includes horizontal and vertical movement, or one of them.

[0117] like Figure 8 and Fig. 9 As shown, auxiliary plates 44 are movably provided on both sides of the lying board 4, and the auxiliary plates 44 are used to increase the prone lying area of ​​the lying board 4 so as to be suitable for different patients.

[0118] A positioning bead structure can be used between the auxiliary plate 44 and the lying plate 4, and a groove track structure can be used. That is, the auxiliary plate 44 is provided with a convex strip, and the lying plate 4 is provided with a groove track corresponding to the convex strip, and the convex strip is located in the groove track to achieve movement and guidance.

[0119] At the same time, limit strips 45 are arranged on both sides of the lying board 4, and the limit strips 45 are used to prevent the patient from moving out of the side of the lying board 4. And for the auxiliary board 44 above, the limit strips 45 can be arranged on the auxiliary board 44, so that the auxiliary board 44 can be easily pulled out while limiting.

[0120] like Figure 1 and Fig. 9 As shown, the lying board 4 is provided with a limit plate 46 corresponding to the patient's shoulder. Therefore, in actual use, when the patient is in a state of lowering the head and raising the waist, the limit plate 46 is used to prevent the patient from moving out of the lying board 4.

[0121] Meanwhile, the limiting plate 46 can be configured to be movable up and down, and the moving structure of the limiting plate 46 can be similar to the moving structure of the auxiliary plate 44 .

[0122] like Figure 7 As shown, in order to provide a better supporting effect, a supporting block 13 is provided on the side of the base 1 close to the patient's head.

[0123] At the same time, a support rod is provided on one side of the base 1, and the support rod includes an inner rod 14 and an outer rod 15, and the inner rod 14 is movably arranged on the outer rod 15, and the top of the inner rod 14 abuts against the lower surface of the lying plate 4 to prevent the lying plate 4 from tilting. The limit between the inner rod 14 and the outer rod 15 can be achieved by positioning beads.

[0124] Therefore, in actual use, the top of the inner rod 14 abuts against the lower surface of the lying board 4 to prevent the lying board 4 from tilting, and the inner rod 14 can be retracted into the outer rod 15 when not in use, so as to avoid the influence of the inner rod 14 when doing other things, and it can also be adjusted to the lying boards 4 of different heights to ensure the support effect.

[0125] Moreover, a gripping rod is provided on the lower surface of the lying board 4, and gripping parts are provided on both sides of the gripping rod. If the patient can hold on, the gripping rod and the gripping part can be provided so that the patient can hold on and avoid sliding off the lying board 4.

[0126] The above shows and describes the basic principle and main features of the present invention and the advantages of the present invention. At the same time, the present invention is not limited by the above embodiments, so without departing from the principle and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
