Description

Technical Field

[0001] This utility model belongs to the technical field of medical equipment, specifically relating to a cardiac compression device, a hospital bed equipped with the cardiac compression device, and an ambulance equipped with the hospital bed. Background Technology

[0002] The term "hospital bed" as used in this application includes beds in various hospital departments, transport beds for transferring patients within the hospital, and patient beds used in ambulances. The term "ambulance" as used in this application includes emergency vehicles, transport ambulances, and mobile medical vehicles. Transport ambulances include hospital transport vehicles and vehicles used by other social organizations for transporting patients. Critically ill patients may experience cardiac arrest in their beds, especially in ambulances and emergency room beds. In such cases, it is crucial to begin chest compressions immediately; otherwise, the patient may suffer irreversible damage to the brain and other vital organs due to ischemia. Traditional chest compressions have two methods: electric and manual. However, electric CPR machines are expensive and have low adoption rates; manual compressions are strenuous, difficult to control in terms of depth, and often result in insufficient compression depth due to the rescuer's fatigue.

[0003] To address this, lever-type manual chest compression devices have been designed, such as the lever-type manual chest compression device disclosed in CN205964435U. This device features a bed edge clamp (also known as a clamp head) with a horizontal locking mechanism oriented horizontally. During compressions, the medical staff stands on the side of the bed (i.e., the side of the bed from which the rescuer is positioned) and grasps the swing end of the compression lever to swing it up and down. Before compressions begin, bolts are used to lock the bed edge clamp to the bed frame on the opposite side (i.e., the other side of the bed from which the rescuer is positioned).

[0004] The existing lever-type manual mechanical pressing devices have the following shortcomings:

[0005] 1. Installation is troublesome, time-consuming, and laborious:

[0006] 1. After inserting the bed edge clamps into the bed frame, the bolts need to be tightened before pressing can begin. This is not conducive to the rapid and efficient use of time for CPR. This is because each press of the lever consists of two phases: a downward press and an upward return. During the downward press phase, the downward pressure required on the second end of the lever can reach tens of kilograms. Correspondingly, pressing the first end of the lever generates an upward pull of tens of kilograms on the bed edge clamps. Therefore, if the clamp bolts are not tightened even slightly, they will become increasingly loose as pressing continues, eventually causing the clamps to suddenly slip out of the bed frame. This slippage usually occurs when the rescuer is pressing down forcefully, making it easy for the person performing the CPR to lose their balance. The bed frame clamp may also injure people around it if it pops out. In addition, since the rescuer is standing on the side of the bed and the clamp is located on the opposite side of the bed frame, the line of sight is usually blocked by the mattress (the bed surface is always higher than the bed frame). The rescuer cannot see the clamp slipping and it is difficult to prevent.

[0007] 2. The aforementioned lever-type manual pressing device is complex in shape and difficult to move because: both the upright and the pressing lever are quite long, forming a V-shape, and they can swing relative to each other around the pivot. Therefore, the included angle of the V-shape is not fixed, meaning that the upright and the pressing lever form an unstable V-shaped structure. So, during the moving and installation process, it is necessary to stabilize both wings of the V-shape simultaneously, stabilizing both the pressing lever and the upright. If the pressing lever is held with only one hand, the upright will sway significantly and cannot be held steadily; conversely, if the upright is held with only one hand, the pressing lever and the clamp will shake significantly and cannot be held steadily. Therefore, the above-mentioned compression device generally requires two people to complete the installation. The first person holds the compression lever on the side of the bed, and the second person on the opposite side of the bed fastens the clamp of the upright into the bed frame and tightens it. If the user only stands on the side of the bed (that is, the side where the person performing the compression is relative to the bed), it is impossible to complete the installation. The user needs to move to the opposite side of the bed (that is, the other side of the person performing the compression) to complete the installation.

[0008] 3. In particular, the installation structure of the aforementioned lever-type manual compression device is even more difficult to apply to patients lying on beds in ambulances, because the internal structure of a conventional ambulance compartment, such as... Figure 1As shown, the leftmost part of the vehicle interior contains a cabinet 81 for storing first-aid supplies, and the rightmost part contains a seat 82. A passage 80 must be left between the seat 82 and the bed 7. Therefore, the left edge of the bed 7 is very close to the cabinet 81, making it impossible for paramedics to enter the space between the left side of the bed and the cabinet 81. Consequently, it is difficult to screw the bed edge clamp onto the left side of the bed frame (the operating space is very limited). If a patient experiences cardiac arrest during transport, for ambulances without an electric cardiopulmonary resuscitation machine, only manual chest compressions remain as an emergency option. If a lever-type manual chest compression device cannot be installed, manual compressions are the only option. However, performing manual CPR in a speeding ambulance presents significant difficulties, drawbacks, and risks: First, the lateral width of the aisle between the transport bed and the seat is too narrow for medical personnel to kneel, forcing them to perform the procedure in a semi-squatting, semi-standing position, which severely hinders their ability to perform the procedure effectively. Second, the bumps and swaying caused by the high-speed movement of the ambulance make it difficult to control the pressure and depth of the compressions. More seriously, in the event of emergency braking, sharp turns, or sudden bumps, the medical personnel performing the compressions are prone to falling, posing a significant risk. Therefore, current guidelines do not encourage medical personnel to perform CPR in speeding ambulances. In practice, the first medical personnel need to sit and hold the second medical personnel firmly around the waist, while the second medical personnel performs manual CPR in a semi-squatting, bent-over position to prevent them from falling. This is very inconvenient and results in poor compression quality.

[0009] 4. Similarly, the installation structure of the aforementioned lever-type manual mechanical chest compression device is particularly unsuitable for patient transport beds (i.e., transfer beds). This is because when a patient experiences cardiac arrest during intra-hospital transfer, the transfer bed must be moved quickly to reach a room with resuscitation facilities as soon as possible. However, due to the cumbersome installation of the lever-type manual mechanical chest compression device, the bolts of the clamps can only be tightened properly when the transfer bed is stopped (i.e., stationary). If the transfer bed is stopped to perform chest compressions, other resuscitation methods cannot be carried out quickly. Therefore, in order to save every second for the patient, some medical staff even jump onto the rapidly moving transfer bed to perform chest compressions on the patient. Although this scene is touching and commendable, there is also a risk of medical staff falling due to the swaying, turning, and narrowness of the transfer bed (carriage). In addition, the narrowness of the transfer bed also restricts the compression posture of the rescuer, making it difficult to control the compression force and standardize the compression movements. Therefore, the compression effect is generally poor.

[0010] II. During the compression process, although the compression device is fixed to the bed frame 84 using locking bolts 8 and clamps 83, such as Figure 2As shown, the entire pressing device is prone to unexpected deflection around the vertical central axis of the locking bolt 8. Consequently, the horizontal positions of the clamp 83, the pressing lever 2, and the pressing head 1 also experience unexpected horizontal deflection around the vertical central axis of the locking bolt 8. The direction of this horizontal deflection is as follows: Figure 2 As indicated by the arc arrow, this causes a deviation in the pressing position of the compression head 1. For example, during patient transport in an ambulance or hospital, when the ambulance or transport bed turns, the compression lever is prone to horizontal deflection, causing the horizontal position of the compression head to deviate and affecting the quality of compression. Utility Model Content

[0011] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cardiac compression device, a hospital bed, and an ambulance equipped with the hospital bed, which is easy and quick to install.

[0012] The cardiac compression device of this utility model is implemented by the following scheme: A cardiac compression device includes a compression head, a compression lever, a swing shaft, and a fastener for connecting to a hospital bed. The swing shaft is vertically connected to the compression lever. The compression head is installed in the middle of the compression lever and swings up and down around the swing shaft along with the compression lever. The swing shaft extends longitudinally and is installed on a shaft lug. The fastener is a metal groove for fastening to the longitudinal railing of the hospital bed. The metal groove includes a groove bottom and left and right side plates, wherein the vertical dimension of the first side plate is larger than the vertical dimension of the second side plate. The semi-enclosed space between the groove bottom and the left and right side plates forms a groove for accommodating the longitudinal railing of the hospital bed, and the groove opening faces upward. The swing shaft is close to the upper half of the metal groove, and the shaft lug of the swing shaft is fixedly welded, riveted, or bolted to the upper half of the metal groove. The shaft lug of the swing shaft is connected to the groove bottom of the metal groove through the first side plate of the metal groove. The swing shaft is located above the groove.

[0013] The metal channel strip is fixed with magnets that magnetically engage with the longitudinal railing strips of the hospital bed.

[0014] The left and right side plates of the metal channel strip are locked together with the longitudinal railing strip of the hospital bed.

[0015] The lugs of the swing shaft are welded, riveted, or bolted to the upper part of the first side plate of the metal groove.

[0016] The metal channel also includes a top plate, which is connected to the top edge of the first side plate. The lug of the swing shaft is welded, riveted, or bolted to the upper surface of the top plate. The vertical distance between the top plate and the top edge of the second side plate is greater than the outer diameter of the longitudinal railing of the hospital bed. The lug of the swing shaft is connected to the bottom of the channel through the top plate and the first side plate of the metal channel.

[0017] The pendulum has two lugs, which are arranged one in front of the other.

[0018] The hospital bed of this utility model is implemented by the following scheme: a hospital bed, including a bed frame and a guardrail, the guardrail being provided with longitudinal railings, the main feature of which is that it is also provided with any of the above-mentioned cardiac compression devices.

[0019] The ambulance of this utility model is implemented by the following scheme: an ambulance, wherein the ambulance compartment is equipped with seats, characterized in that: the ambulance compartment is equipped with the aforementioned hospital bed next to the seats.

[0020] The term "longitudinal" refers to the length of the hospital bed, that is, the direction of the patient's height when lying down; the term "transverse" refers to the horizontal direction perpendicular to the longitudinal direction.

[0021] The hospital bed is equipped with a guardrail to prevent patients from falling. The guardrail has longitudinally extending rails, which are referred to as "longitudinal rails" in this application document.

[0022] The hospital bed has left and right sides. The side where the rescuer is pressing down is called the "bed side," and the side opposite the bed side is called the "opposite side." The bed side is the side where the swing arm of the compression lever is located, and the opposite side is the side where the metal groove and swing shaft are located.

[0023] This utility model has the following advantages and effects:

[0024] 1. Once the metal channel bar is secured to the outside of the longitudinal railing of the hospital bed (i.e., the longitudinal railing is inserted into the groove of the metal channel bar), downward pressing can begin immediately. The reasons are as follows: During the downward pressing phase, the metal channel bar is only subjected to a vertical upward pulling force. Moreover, since the groove opening faces upward and the bottom of the metal channel bar is directly below the pivot, the metal channel bar can automatically withstand a pure upward pulling force of tens of kilograms without any external assistance. It is impossible for the metal channel bar to slip off during the pressing process, further preventing the rescuer from suddenly losing stability. On the other hand, during the upward return phase of the pressing action, the patient's chest is in the recovery phase of upward elastic bulging due to its own elasticity. During this phase, the patient's chest will exert an upward force on the pressing head and the pressing lever. This upward force can completely overcome the slight weight of the metal channel bar itself, thus preventing the metal channel bar from slipping downward relative to the longitudinal railing of the hospital bed. Therefore, once the metal channel strip is fastened to the outside of the longitudinal guardrail strip, pressure can be applied immediately. This saves valuable time, allowing for earlier blood supply to the patient's brain and preventing prolonged cerebral ischemia (in contrast to traditional techniques, where bolts must be tightened forcefully and confirmed to be secure before pressure can begin). Thus, the rescuer with this invention does not even need to walk to the opposite side of the bed to tighten the bolts, making installation quick and time-saving.

[0025] Second, in some embodiments of this utility model, only a slight clamping force or magnetic force is needed to further position the metal groove strip, thereby preventing the metal groove strip from falling off and detaching from the longitudinal railing of the hospital bed during pauses in pressing.

[0026] Third, this utility model fixes the metal channel strip to the longitudinal railing strip of the hospital bed, rather than locking it to the bed frame, and the axle lug is welded / riveted / bolted to the upper half of the metal channel strip, with the swing shaft close to the upper half of the metal channel strip, which brings the following advantages:

[0027] 1. The distance between the balance shaft and the metal groove is very small, which further brings the following advantages and effects:

[0028] (1) Easy to use. During the use process, you only need to hold the pressing lever with one hand, without having to hold the metal groove (because the metal groove is close to the pivot, even if it swings around the pivot, the swing amplitude is very small, and you will not lose your grip due to large swing amplitude); (2) The distance between the pivot and the groove of the metal groove is small, so the metal groove does not easily swing or the swing amplitude is small. The position of the groove is easy to control during the installation process, so that the rescuer only needs to stand on the side of the bed, hold the pressing lever and hook the metal groove to the longitudinal railing bar on the opposite side of the bed, and then start the first downward press as soon as possible; (3) The vertical size of the entire pressing device is greatly reduced, so that the entire pressing device has a simple shape and fewer large-scale rod components, so that the entire device will not form an unstable V-shape, which makes it easy to pick up and move the device, and also saves the cost of the device. It has storage space; (4) For the circular longitudinal railing of the hospital bed, the swing shaft may not be able to be precisely located above the longitudinal railing of the hospital bed when it is first installed. That is, the swing shaft may be slightly biased to the upper side of the longitudinal railing of the hospital bed. After pressing hard, due to the vertical upward pulling force, the swing shaft will be automatically returned to the center. That is, the metal groove will rotate around the longitudinal railing and the swing shaft will be pulled to the upper side of the longitudinal railing of the hospital bed. However, since the distance between the swing shaft and the longitudinal railing of the hospital bed is very small, the swing shaft will shift laterally during the above deflection process. This means that the lateral position of the pressing head will also be very small and negligible. This is conducive to ensuring that the lateral position of the pressing head during the second pressing action is basically consistent with the lateral position of the pressing head during the first pressing action, and keeping the pressing position accurate.

[0029] 2. Since the vertical position of the longitudinal railings of the hospital bed is generally higher than the bed surface and not much different from the vertical position of the patient's chest, it means that the vertical position of the metal groove is also similar to that of the patient's chest. Since the swing shaft is close to the metal groove, the vertical position of the swing shaft is also not much different from that of the patient's chest. This helps to reduce the amplitude of the lateral movement of the contact point between the compression head and the chest during compression, keeping the amplitude of this lateral movement within an acceptable range (only about a few millimeters).

[0030] 3. Although the presser and the metal channel are located on opposite sides of the bed, the metal channel is exposed within the presser's (installer's) line of sight during installation and throughout the entire pressing process, making it convenient for the presser to install, control, and observe.

[0031] IV. This utility model can effectively prevent the swing shaft and pressing swing rod from horizontally deflecting around the vertical axis, thereby avoiding inaccurate pressing position of the pressing head and ensuring pressing quality. The reasons are as follows: The left and right side plates of the metal channel strip are sandwiched between the left and right sides of the longitudinal railing strip, thus preventing the metal channel strip from horizontally deflecting around the vertical central axis. The shaft lug of the swing shaft is fixed to the upper part of the metal channel strip, so the pressing swing rod and pressing head will not horizontally deflect relative to the longitudinal railing strip.

[0032] In summary, this invention utilizes the cooperation between the upward-opening metal channel strip, the longitudinal railing strip of the hospital bed, and the lever structure, as well as the axle lugs for fixing the swing shaft using the metal channel strip. This makes the installation process of attaching the compression device to the hospital bed convenient, eliminating the need to move to the other side of the bed to tighten the clamp (therefore it is particularly suitable for hospital beds in ambulances). Furthermore, the swing end of the compression lever is close to the seat, allowing paramedics to easily and safely perform compressions on patients while seated in a speeding ambulance, without the risk of falls or injuries. The device can also be installed while the hospital bed is moving (i.e., during patient transport), making it particularly suitable for emergency transport on transport beds. Additionally, this invention helps ensure the accurate positioning of the compression head. Attached Figure Description

The swing shaft 3 is vertically connected to the compression lever 2. The compression head 1 is installed in the middle of the compression lever 2 and swings up and down around the swing shaft 3 along with the compression lever 2. The lateral position of the compression head 1 can be finely adjusted by sliding along the compression lever 2 and is fixed by a vertical bolt 11. The swing shaft 3 extends longitudinally and has two lugs 4 arranged one in front of the other. The front and rear ends of the swing shaft 3 are rotatably fitted onto the lugs 4. The end of the compression lever 2 has a longitudinally extending handle 21. The fastener is a metal groove 5 for fastening to the longitudinal railing of the hospital bed. The metal groove 5 is long and extends longitudinally. The metal groove 5 includes a groove bottom 53 (i.e., groove bottom plate) and left and right side plates (first side plate 51 and second side plate 52), wherein the vertical dimension of the first side plate 51 is ( Figure 4 The vertical distance between the middle CD and the second side panel 52 is greater than the vertical dimension of the second side panel 52. Figure 4 The vertical distance between AB and the bottom 53 of the groove and the semi-enclosed space between the left and right side panels forms a groove 50 to accommodate the longitudinal railing strip 71 of the hospital bed. The groove 50 extends longitudinally, and the opening of the groove faces upward (e.g., the vertical distance between AB and the bottom 53 of the groove and the left and right side panels). Figure 4(As indicated by the middle arrow); the swing shaft 3 is located near the upper part of the first side plate 51 (the upper part of the first side plate 51 belongs to the upper half of the metal groove), and the shaft lug 4 of the swing shaft is fixedly welded to the upper half of the first side plate 51. The shaft lug 4 of the swing shaft is connected to the bottom 53 of the metal groove through the first side plate 51 of the metal groove; the swing shaft 3 is located above the groove 50, and the shaft lug 4 of the swing shaft is connected to the top edge of the second side plate of the metal groove ( Figure 4 The distance between point B and point C ( Figure 4 The distance between the middle EB is greater than the outer diameter of the longitudinal railing strip 71 of the hospital bed; a non-falling structure is also provided to prevent the metal channel strip 5 from sliding down relative to the longitudinal railing strip 71 of the hospital bed. The non-falling structure refers to the left and right side plates (first side plate 51 and second side plate 52) of the metal channel strip forming a clamping fit with the longitudinal railing strip 71 of the hospital bed. The second side plate 52 is partially recessed inward toward the groove cavity of the groove 50 to form a clamping part 520 that can clamp the longitudinal railing strip 71 of the hospital bed. The normal distance between the clamping part 520 and the first side plate 51 is slightly smaller than the diameter of the longitudinal railing strip 71 of the hospital bed. Example 2

[0048] A hospital bed for use in an ambulance includes a bed frame 7 and a guardrail 70. The guardrail 70 is provided with longitudinal railings 71. The hospital bed is also equipped with a CPR device as described in Embodiment 1 above. During installation, the rescuer can be positioned on the side of the bed and hold the lever 2 to move the metal channel 5, allowing the longitudinal railings 71 of the bed to pass through the seam 55. Figure 4 The gap between the middle and EB) leads to the groove 50. The metal channel strip 5 is fastened to the longitudinal railing strip 71 of the hospital bed, and the locking part 520 locks the longitudinal railing strip 71 of the hospital bed to prevent the metal channel strip 5 from falling off. Figure 5 , Figure 6 As shown; after use, the metal groove 5 can be detached from the longitudinal railing 71 of the hospital bed, and the entire heart compression device can be temporarily removed from above the hospital bed surface. Example 3

[0049] An ambulance is provided with seats 82 and equipment cabinets 81 inside the ambulance compartment. A hospital bed, as described in Embodiment 2, is located next to the seats 82 inside the ambulance compartment. The left side of the bed frame 7 is close to the equipment cabinet 81.

[0050] Example 4 is a cardiac compression device. The main differences between Example 4 and Example 1 are in the following four aspects, such as... Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 As shown:

[0051] 1. The anti-fall structure in Embodiment 4 refers to the fact that the bottom of the metal channel strip 5 is fixed with a magnet 6 that forms a magnetic attraction with the longitudinal railing strip 71 of the hospital bed; after the metal channel strip 5 is fastened to the longitudinal railing strip 71 of the hospital bed, the magnet 6 attracts the bottom 53 of the metal channel strip and the longitudinal railing strip 71 of the hospital bed together, and the second side plate 52 of the metal channel strip in Embodiment 4 does not need to form a concave clamping part;

[0052] 2. The metal channel in Embodiment 4 also includes a top plate 54, which is connected to the top edge of the first side plate 51.
