Abstract
Description
Technical Field
[0001] This invention belongs to the field of emergency and critical care technology, specifically relating to a cardiopulmonary resuscitation device for clinical use in the emergency department. Background Technology
[0002] When a patient experiences fainting or other symptoms, cardiopulmonary resuscitation (CPR) should be performed immediately. The compression point is usually two finger-widths above the xiphoid process. The compression should be performed by overlapping the hands, with the heels of the palms touching the chest wall and the fingers raised but not touching the chest wall. Ensure strong compression and allow the chest wall to rebound normally. This can effectively promote blood circulation and the recovery of cardiopulmonary function, resulting in a good rescue effect and reducing the risk of death for the patient.
[0003] Patent CN210962988U discloses a cardiac resuscitation machine for a mobile emergency bed, comprising: a main cardiac resuscitation device, a connecting rod, and a sleeve. A left slider is connected to the upper left side of the sleeve, and a right slider is connected to the right side. The left slider is fitted onto the outside of a left slide rail, and the right slider is fitted onto the outside of a right slide rail. Both the left and right slide rails are connected to the lower end of the emergency bed. The patient lies on the emergency bed. The connecting rod has a U-shaped structure, with one end movably inserted into the sleeve and the other end fixedly connected to the main cardiac resuscitation device. In use, the mobile emergency bed cardiac resuscitation machine is inserted into the sleeve and can move left and right with the sleeve to adjust to a suitable position.
[0004] When using the above technical solution, the cardiac resuscitation machine needs to be moved to a position two finger-widths above the xiphoid process of the patient's body. Due to the urgency of emergency situations, when medical staff use the mobile emergency bed cardiac resuscitation machine provided by the above technical solution, they first need to adjust the position of the mobile emergency bed cardiac resuscitation machine in both the horizontal and vertical directions so that the cardiac resuscitation machine is located above the xiphoid process of the patient's body. This makes it impossible to quickly position the cardiac resuscitation machine, wasting rescue time.
[0005] Furthermore, in practice, when performing CPR on a patient, it is necessary to elevate the patient's chin to open the airway. After multiple chest compressions during CPR, two or more artificial breaths should be performed to improve the success rate of CPR. However, the above technical procedures require the cooperation of medical staff and are complex to operate. Summary of the Invention
[0006] The purpose of this invention is to overcome the problems of existing cardiopulmonary resuscitation (CPR) devices, which cannot quickly locate the CPR device, wasting rescue time, and cannot elevate the patient's chin to open the airway.
[0007] To achieve the above objectives, the technical approach adopted in this invention is as follows: A compression mechanism and a neck support mechanism are added to the hospital bed frame, wherein the compression mechanism and the neck support mechanism are positioned in contact. In this way, medical personnel only need to place the patient's neck on the support airbag in the neck support mechanism, and then remove the compression mechanism from under the hospital bed frame. This removes the compression mechanism from contact with the neck support mechanism, allowing the neck support mechanism to elevate the patient's neck and open the airway. Simultaneously, the compression mechanism rotates after being raised so that the compression block is positioned two finger-widths above the xiphoid process of the patient's body, facilitating multiple cardiopulmonary resuscitation compressions.
[0008] Based on the above technical concept, the technical solution adopted by this invention is as follows:
[0009] An emergency department clinical cardiopulmonary resuscitation device includes a bed frame, on which are equipped:
[0010] The pressing mechanism includes a support and a pressing block set on the upper end of the support; the lower end of the support is connected to the bed frame.
[0011] The neck support mechanism includes a support airbag mounted on the bed frame and a drive assembly mounted on the bed frame; one end of the drive assembly is connected to the support airbag and the other end abuts against the support frame.
[0012] In the above technical solution, preferably, the support includes:
[0013] The lifting linkage is connected to the pressing block;
[0014] A rotary motor is located on the side of the lifting linkage. The output end of the rotary motor is equipped with a drive gear, which is connected to the lifting linkage.
[0015] Further specifying the above technical solution, the lifting linkage includes:
[0016] The lifting linkage includes:
[0017] The first push rod, the push rod part of the first push rod is connected to the pressing block;
[0018] The second push rod has a push rod portion connected to the fixed end of the first push rod, and the push rod portion of the second push rod abuts against the drive assembly;
[0019] A ball screw is installed under the bed frame; a threaded block is fitted on the ball screw, the top of the threaded block is rotatably connected to the bottom of the fixed end of the second push rod, and the threaded block is connected to the side of the rotary motor.
[0020] To further define the above technical solution, a driven gear that meshes with the driving gear is provided on the outer side of the fixed end of the second push rod.
[0021] To further define the above technical solution, the push rod portion of the second push rod has an inverted L-shaped structure.
[0022] To further specify the above technical solution, the driving component includes:
[0023] The movable hole is located on the bed frame; the upper end of the movable hole is connected to the support airbag.
[0024] The piston rod has an L-shaped structure, with a counterweight at the long arm end and the short arm end passing through the movable hole and connecting to a square piston that slides inside the movable hole; the long arm end of the piston rod abuts against the second push rod.
[0025] The rotating connector has one end connected to the bottom surface of the hospital bed and the other end rotatably connected to the middle position of the piston rod.
[0026] The spring is pressed, with one end connected to the bottom of the bed and the other end rotatably connected to the long arm of the piston rod.
[0027] The above technical solution is further specified to include: an oxygen inhalation assist mechanism for assisting artificial respiration, wherein the oxygen inhalation assist mechanism is connected to an oxygen tank.
[0028] To further specify the above technical solution, the oxygen inhalation support mechanism includes:
[0029] Nose clips;
[0030] The oxygen delivery system is connected to the nose clip and the oxygen tank, respectively.
[0031] To further specify the above technical solution, the oxygen inhalation component includes:
[0032] The oxygen cannula is rotatably connected to the center of the nasal clip.
[0033] The air supply bag has an air inlet connected to the oxygen tank via a first one-way valve, and an air outlet connected to the oxygen inhalation tube via a second one-way valve. Beneficial effects
[0034] I. This invention, through the combined design of a hospital bed, a compression mechanism, and a neck support mechanism, requires only that medical staff place the patient's neck on the support airbag in the neck support mechanism. After the compression mechanism is moved out from under the hospital bed, it only needs to be adjusted in the longitudinal direction of the bed to position the compression block two finger-widths above the xiphoid process of the patient's body for cardiopulmonary resuscitation (CPR) compressions. At the same time as the compression mechanism is moved out from under the hospital bed, the support airbag in the neck support mechanism inflates to elevate the patient's neck and open the airway. Before assisted breathing, foreign objects or secretions in the mouth should be cleared.
[0035] II. This invention utilizes a combined design of a piston rod, a counterweight, and a second push rod. After the push rod portion of the second push rod rotates horizontally, it moves away from the end of the piston rod where the counterweight is located. Consequently, the end of the piston rod connected to the counterweight moves downward under the weight of the counterweight, causing the end of the piston rod away from the counterweight to move upward within the receiving cavity of the hospital bed. This inflates the support airbag connected to the receiving cavity of the hospital bed, thus providing support for the patient's neck. The structure is simple and easy to use.
[0036] Third, this invention utilizes a combined design of a nasal clip and an oxygen delivery assembly. Medical staff only need an air delivery bag to clamp the patient's nose with the nasal clip while simultaneously opening a second one-way valve at the air delivery bag's outlet. At this time, the first one-way valve closes, allowing oxygen from the air delivery bag to be blown into the patient's mouth. After the medical staff releases the clip, the first one-way valve at the air delivery bag's inlet opens, and the second one-way valve closes, allowing oxygen from the oxygen tubing to enter the air delivery bag. This ensures sufficient airflow for the next breath into the patient's mouth, allowing for chest rise and fall. Thus, medical staff can perform cardiopulmonary resuscitation without artificial respiration, reducing cross-infection between medical staff and patients and ensuring medical safety.
[0037] Fourth, this invention, through the combined design of a pressing spring and a counterweight, can more quickly press down the end of the L-shaped connecting rod, causing the square piston located at the other end of the L-shaped connecting rod to move upward within the movable hole, thereby inflating the supporting airbag; wherein, the L-shaped connecting rod and the square piston are rotatably connected, so that when the L-shaped connecting rod rotates around the rotating connector, the square piston will not get stuck in the movable hole.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0060] In the description of this invention, it should be understood that the terms "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0061] Furthermore, the use of the terms "first" and "second" may explicitly or implicitly include one or more of those features. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0062] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0063] The inventors discovered that current cardiopulmonary resuscitation (CPR) devices require the CPR machine to be moved two finger-widths above the xiphoid process of the patient. Due to the urgency of emergency situations, medical personnel using the mobile emergency bed CPR machine provided by the above-mentioned technical solution first need to adjust the position of the mobile emergency bed CPR machine in both the horizontal and vertical directions so that the CPR machine is located above the xiphoid process of the patient, which makes it impossible to quickly position the CPR machine and wastes rescue time.
[0064] In addition, when performing cardiopulmonary resuscitation on patient 5, it is necessary to elevate patient 5's chin to open the airway. After multiple chest compressions during cardiopulmonary resuscitation, two or more artificial breaths should be performed to improve the success rate of cardiopulmonary resuscitation. However, the above technical procedures require the cooperation of medical staff and are complicated to operate.
[0065] Based on the above findings, this application proposes an emergency department clinical cardiopulmonary resuscitation (CPR) device. This device includes a hospital bed 4, and a compression mechanism 1, a neck support mechanism 2, and an oxygen support mechanism 3, all mounted on the hospital bed 4. By installing the compression mechanism 1 on the side of the hospital bed 4, when CPR is needed for a patient 5, the compression mechanism 1 can be rotated after the patient 5 is moved onto the hospital bed 4 to perform multiple compressions. 1. The compressions replace manual compressions, and the compression frequency and force can be adjusted according to actual needs, resulting in better resuscitation effects; 2. While rotating the compression mechanism 1, the neck support airbag 21 in the neck support 2 inflates to elevate the patient's neck and open the airway. Before assisted breathing, foreign objects or secretions in the mouth should be cleared; 3. After multiple compressions of the patient, the oxygen inhalation assistive mechanism 3 can be used to blow air into the patient's mouth, replacing artificial respiration, avoiding cross-infection between medical staff and patients, and ensuring medical safety.
[0066] Example 1
[0067] This embodiment provides a cardiopulmonary resuscitation device for emergency department clinical use, such as... Figure 1-15 As shown, it includes a hospital bed body 4, and a pressing mechanism 1, a neck support mechanism 2, and an oxygen inhalation assist mechanism 3 installed on the hospital bed body 4.
[0068] A crossbar 41 is provided on the lower side of the bed body 4 and is fixedly connected to the bed leg. The crossbar 41 is parallel to the bed body 4. The crossbar 41 is provided with a mounting groove for fixing the pressing mechanism 1.
[0069] like Figure 1 and 10 As shown, the pressing mechanism 1 includes a bracket and a pressing block 11 disposed on the bracket;
[0070] The bracket includes a rotary motor 12 and a lifting linkage mounted on the rotary motor 12. The end of the lifting linkage away from the rotary motor 12 is connected to the pressing block 11. The lifting linkage includes a first push rod 13, a second push rod 14, and a ball screw 15.
[0071] Specifically, the rotary motor 12 is installed on the side of the mounting slot of the crossbar 42, and the side of the rotary motor 12 is in contact with the inner wall of the mounting slot.
[0072] The output end of the rotary motor 12 is provided with a drive gear 12a, which is used to control the rotation of the bracket; wherein, the side of the rotary motor 12 is connected to a threaded block sleeved on the ball screw 15.
[0073] Among them, the ball screw 15 is horizontally set in the mounting groove of the crossbar 41, and the threaded end of the ball screw 15 is rotatably connected to the inner wall of the mounting groove.
[0074] The threaded block sleeved on the ball screw 15 is rotatably connected to the fixed end of the second push rod 14. When in use, the position of the threaded block sleeved on the ball screw 15 can be adjusted according to the height of the patient 5 so that the pressing block 11 can be accurately positioned two finger widths above the xiphoid process of the patient 5.
[0075] Thus, in practical applications, the side of the rotary motor 12 contacts the inner wall of the mounting groove, so that the rotary motor 12 is limited between the threaded block sleeved on the ball screw 15 and the inner wall of the mounting groove. Therefore, during the movement of the threaded block sleeved on the ball screw 15, the threaded block sleeved on the ball screw 15 will not rotate with the threaded rod of the ball screw 15. That is, the threaded block sleeved on the ball screw 15 and the rotary motor 12 connected to the threaded block both move linearly on the horizontal plane.
[0076] Specifically, the second push rod 14 is a hydraulic rod, and its fixed end is provided with a driven gear 14a. A rotating rod is located at the center of the end of the driven gear 14a furthest from the second push rod 14. The rotating rod is rotatably connected to the upper surface of the threaded block fitted on the ball screw 15. The push rod portion of the second push rod 14 has an inverted L-shaped structure, which allows the edge of the first push rod 13 and the pressing block 11 located at the end of the first push rod 13 to be positioned at the center of the patient's body.
[0077] The driving gear 12a meshes with the driven gear 14a to control the rotation of the second push rod 14 via the control motor 12. The push rod portion of the second push rod 14 has an L-shaped structure, and the free end of the push rod portion of the second push rod 14 is connected to the fixed end of the first push rod 13. The push rod portion of the first push rod 13 is fixedly connected to the pressing block 11.
[0078] In this way, during use, the pressing block 11 can be moved up and down repeatedly by controlling the push rod part of the first push rod 13 to extend or retract repeatedly, so as to perform cardiopulmonary resuscitation compressions on the patient 5.
[0079] like Figure 4 , 9 As shown in Figures 1 and 12, the neck support mechanism 2 includes a support airbag 21 and a drive assembly connected to the support airbag 21. The drive assembly includes an actuating hole 22, a piston rod 23, a rotating connector 24, a pressing spring 25, and a counterweight 26.
[0080] The movable hole 22 is a square through hole, and the movable hole 22 is connected to the support airbag 21 installed on the bed frame 4;
[0081] The piston rod 23 has an L-shaped structure. The long arm end of the piston rod 23 is provided with a counterweight 26, and the short arm end passes through the movable hole 22 and is connected to the square piston 23a that is slidably disposed in the movable hole 22. The long arm end of the piston rod 23 abuts against the second push rod 14.
[0082] Specifically, the square piston 23a is horizontally arranged inside the movable hole 22 and is sealed to the inner wall of the movable hole 22. One end of the piston rod 23 is inserted into the movable hole 22 and rotatably connected to the square piston 23a, while the other end is located outside the movable hole 22 and connected to the counterweight 26.
[0083] The rotating connector 24 is located between the square piston 23a and the counterweight 26. The upper end of the rotating connector 24 is fixedly connected to the bed frame 4, and the lower end is rotatably connected to the piston rod 23. Specifically, the rotating connector 24 has a U-shaped structure, including a rotating rod and two connecting pieces located on both sides of the rotating rod. The upper end of each connecting piece is fixedly connected to the bed frame 4, and the lower end of each connecting piece is fixedly connected to the rotating rod.
[0084] In use, the piston rod 23 has a through hole in the center, and the piston rod 23 is sleeved on the rotating rod of the rotating connector 24 through the through hole to achieve a rotating connection with the rotating connector 24.
[0085] The upper end of the pressing spring 25 is fixedly connected to the bed frame 4, and the lower end is fixedly connected to the end of the piston rod 23 with the counterweight 26. In this way, when the push rod part of the second push rod 14 is no longer in contact with the piston rod 23, the pressing spring 25 can further press the end of the piston rod 23 with the counterweight 26 downward, so that the end of the piston rod 23 connected to the square piston tilts upward, thereby causing the square piston 23a to move upward, realizing the inflation of the support airbag 21, so as to support the neck of the patient 5 and open the airway.
[0086] In practical use, in the initial state, such as Figure 15 As shown, the push rod part of the second push rod 14 is located below the bed body 4, and the push rod part of the second push rod 14 is in contact with the end of the piston rod 23 where the counterweight 26 is provided. At this time, the piston rod 23 is in a balanced state under the support force of the second push rod 14.
[0087] In use, the rotary motor 12 drives the drive gear 12a to rotate, the drive gear 12a drives the driven gear 14a set at the fixed end of the second push rod 14 to rotate, and the driven gear 14a drives the second push rod 14 to rotate 90°, so that the push rod part of the second push rod 14 is parallel to the bed body 4.
[0088] Then, the second push rod 14 is activated, causing the push rod portion of the second push rod 14 to extend so that the first push rod 13 is positioned above the patient 5;
[0089] Then, the rotary motor 12 drives the active gear 12a to rotate in the opposite direction again. The active gear 12a drives the driven gear 14a, which is set at the fixed end of the second push rod 14, to rotate. The driven gear 14a drives the second push rod 14 to rotate 90° in the opposite direction so that the first push rod 13 is aligned with two finger widths above the xiphoid process of the patient 5, so that cardiopulmonary resuscitation can be performed on the patient 5 through the pressing block 11 on the first push rod 13.
[0090] In practical applications, the compression block 11 has a circular structure, with one edge of the compression block 11 located at the center of the patient's body and the other side of the compression block 11 located on the patient's body near the heart. In this way, during actual use, it is only necessary to place the patient's neck at the center of the support airbag 21, so that one side of the compression block 11 is located two finger widths above the xiphoid process of the patient's body, and the other side of the compression block 11 is located near the patient's heart. There is no need to adjust the lateral position of the compression block 11, so as to quickly perform cardiopulmonary resuscitation on the patient.
[0091] Example 2
[0092] Based on Example 1, the difference from Example 1 is as follows: Figure 1 , 3 As shown in Figure 11, the emergency department clinical cardiopulmonary resuscitation device provided in this embodiment of the invention also includes an oxygen inhalation auxiliary mechanism 3, which includes a nasal clip 31, an oxygen inhalation tube 32, and an air delivery bag 33.
[0093] The nasal clip 31 includes a left clip and a right clip, which are rotatably connected. Specifically, the left and right clips have the same structure, and each of the left and right clips has a ring at its center to facilitate the passage of the oxygen cannula.
[0094] The oxygen tube 32 has an L-shaped structure. One end of it passes through the rings set at the center of the left and right clamps in sequence, so as to realize the rotatable connection between the oxygen tube 32 and the nasal clip 31. The other end of the oxygen tube 32 is provided with an air outlet, which is located in the patient's mouth.
[0095] The air supply bag 33 is positioned between the left clamp and the right clamp, and the air supply bag 33 has an air inlet and an air outlet. The air inlet of the air supply bag 33 is equipped with a first one-way valve, and the air outlet of the air supply bag 33 is equipped with a second one-way valve.
[0096] Specifically, the air inlet of the air supply bag 33 is connected to an external oxygen tank via a first one-way valve, and the air outlet of the air supply bag 33 is connected to the oxygen inhalation tube 32 via a second one-way valve. In this way, oxygen from the external oxygen tank enters the air supply bag 33 and then enters the oxygen inhalation tube 32 through the second one-way valve.
[0097] The first one-way valve directs airflow from the oxygen tank to the gas delivery bag 33; the second one-way valve directs airflow from the gas delivery bag 33 to the oxygen inhalation tube 32.
[0098] The working principle of the oxygen inhalation assistive mechanism 3 provided in this embodiment of the invention is as follows: Medical personnel place two fingers on both sides of the left clamp and the right clamp respectively, and then squeeze the air delivery bag 33, so that the oxygen in the air delivery bag 33 enters the oxygen inhalation tube 32 through the second one-way valve, and then the oxygen enters the patient 5's mouth from the oxygen inhalation tube 32; while the medical personnel squeeze the air delivery bag 33, the fixed ends of the left clamp and the right clamp move closer to each other, so that the patient 5's nasal cavity is pinched closed. While the patient 5's nasal cavity is pinched closed, the oxygen in the oxygen inhalation tube 32 enters the patient 5's oral cavity, realizing blowing air into the patient 5's mouth. In this way, medical personnel can perform cardiopulmonary resuscitation on the patient 5 without artificial respiration, reducing cross-infection between medical staff and patients and ensuring medical safety.
[0099] It should be noted that the oxygen tank provided in the embodiments of the present invention is prior art, and the present invention does not make any improvements thereto.
[0100] Example 3
[0101] Based on Embodiment 1, unlike Embodiments 1 and 2, the compression block 11 provided in this embodiment of the invention is provided with a suction cup on its bottom surface. In this way, when performing CPR compressions on a patient, the suction cup on the bottom surface of the compression block 11 comes into contact with the patient's body, thereby generating suction on the patient's body surface. When the compression block 11 moves away from the patient, the patient's body rebounds under the action of the suction cup due to the suction effect on the patient's body surface, thereby preventing the patient's sternum from being excessively compressed and broken.
[0102] In practical applications, the material of the pressing block 11 can be an elastic material; for example, the material of the pressing block 11 is silicone.
[0103] The specific usage process is as follows:
[0104] Mr. Liu, 38 years old, was admitted to the hospital after suffering cardiac arrest.
[0105] Step 1: Move patient 5 onto bed 4, with patient 5's neck positioned above the support bag 21, place the nasal clip 31 of the oxygen aid mechanism 3 on the bridge of patient 5's nose, and place the air inlet of the oxygen tube 32 into patient 5's mouth.
[0106] Step 2: Turn on the rotary motor 12, so that the drive gear 12a rotates 90°, and then the drive gear 12a drives the second push rod 14 to rotate 90° through the driven gear 14a, so that the push rod part of the second push rod 14 is parallel to the edge of the bed body 4;
[0107] Step 3: Activate the second push rod 14, raising the push rod portion of the second push rod 14 above the patient's body;
[0108] Step 4: Turn on the rotary motor 12 again, so that the active gear 12a rotates 90° in the opposite direction. Then, the active gear 12a drives the second push rod 14 to rotate 90° through the driven gear 14a, so that the first push rod 13 located on the push rod part of the second push rod 14 is located at the center of the patient 5's body.
[0109] Step 5: Turn on the ball screw 15 and adjust the longitudinal position of the pressing block 11 on the end of the push rod part of the first push rod 13 so that the pressing block 11 is located two finger widths above the xiphoid process of the patient's body.
[0110] Step 5: Activate the first push rod 13, so that the push rod part of the first push rod 13 extends repeatedly, so that the compression block 11 can perform multiple compressions on the patient 5's body to achieve cardiopulmonary resuscitation;
[0111] Step Six: After pressing the compression block 11 repeatedly on the patient's body, the first push rod 13 stops pressing, and the medical staff pinches the upper ends of the left and right clamps of the nose clip 31 with two fingers, and then squeezes the air delivery bag 33, so that the oxygen in the air delivery bag 33 passes through the second one-way valve and enters the oxygen inhalation tube 32. Finally, the oxygen enters the patient's mouth from the air delivery port of the oxygen inhalation tube 32 to achieve artificial respiration.
[0112] After repeating step six several times, repeat step five again to perform cardiopulmonary resuscitation on patient 5.
