Description

Technical Field

[0001] This utility model belongs to the technical field of medical devices, specifically relating to a cardiac compression device for a medical transfer bed and a medical transfer bed having the same. Background Technology

[0002] Medical transfer beds, also known as transport beds, trolleys, stretchers, etc., are generally used to move patients, such as beds used to transfer patients between different departments or rooms in a hospital, and beds used to push patients onto or off ambulances.

[0003] Critically ill patients may experience cardiac arrest during transport, and chest compressions are an effective first aid method for cardiac arrest. They involve repeated compressions and expansions of the heart, delivering oxygenated blood back to the brain and keeping it alive. However, chest compressions encounter significant resistance, often requiring the use of both hands. Furthermore, when cardiac arrest occurs during transport, the transfer bed must be moved as quickly as possible to a room with resuscitation facilities. If the transfer bed is stopped to perform chest compressions, other resuscitation methods cannot be initiated promptly. Therefore, in the race against time to save lives, we often see medical personnel in television news or short videos bravely jumping onto rapidly moving transfer beds to perform chest compressions. While these scenes are moving and admirable, the swaying, turning, and narrowness of the transfer bed (vehicle) pose a risk of falls for medical personnel. Additionally, it restricts the rescuer's compression posture, making it difficult to control the pressure and standardize the compression movements, resulting in generally poor compression effectiveness.

[0004] To address this, various solutions have been designed, such as the structure disclosed in the patent publication number CN220558193U, which adds a platform next to the transfer bed. The platform is attached to the outside of the transfer bed and moves synchronously with the transfer bed, allowing medical staff to stand on the moving platform to perform chest compressions. However, the above solution is difficult to popularize and promote because the platform is bulky, occupies a lot of space, and is troublesome to fold or unfold. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a cardiac compression device for a medical transfer bed and a medical transfer bed having the device, which allows rescuers to press with both hands while moving quickly along with the transfer bed.

[0006] The objective can be achieved as follows: A cardiac compression device for a medical transfer bed includes a compression head, a compression lever, a swing shaft, and a bearing for mounting the swing shaft. The swing shaft extends longitudinally, the compression lever is perpendicularly connected to the swing shaft, the compression head is installed in the middle section of the compression lever, and the swing end of the compression lever forms a grip for the rescuer to hold. The device is characterized by further having a fastening element for fastening onto the edge of the medical transfer bed, and the bearing is fixed to the fastening element. When the fastening element is fastened to the first transverse side edge of the transfer bed and the vertical distance between the lower end of the compression head and the bed surface is 20 cm, the horizontal projection of the grip of the compression lever protrudes outside the medical transfer bed, and the transverse dimension of the portion of the compression lever protruding outside the second transverse side edge of the medical transfer bed is greater than 8 cm.

[0007] When the fastener is fastened to the first horizontal side edge of the medical transfer bed and the vertical distance between the lower end of the pressing head and the bed surface is 20 cm, the horizontal dimension of the pressing swing rod protruding from the outer side of the second horizontal side edge of the medical transfer bed is 15-38 cm.

[0008] It is also equipped with a floating upright, the upper end of which is fixedly connected to a pressing swing arm. The floating upright swings up and down around the swing axis along with the pressing swing arm. The lateral position of the upper end of the floating upright is located between the swing end of the pressing swing arm and the pressing head. The lateral position of the floating upright matches the second lateral side edge of the medical transfer bed, so that the second lateral side edge of the medical transfer bed limits the downward swing amplitude of the floating upright.

[0009] The length of the compression lever is extendable. In this case, the lateral dimension of the portion of the compression lever protruding from the outer edge of the second lateral side of the medical transfer bed is determined by the lever being at its maximum extension. Thus, when the medical transfer bed is not being pushed (stationary relative to the ground or relative to the ambulance), the length of the compression lever can be shortened to perform CPR. For example, when a patient experiences cardiac arrest on a transfer bed (i.e., a reclining bed) in an ambulance, and the ambulance is moving while the transfer bed is stationary relative to the ambulance, the compression lever can be shortened to perform CPR (because the lateral space in the ambulance compartment is limited, the compression lever needs to be shortened); conversely, when the reclining bed is being pushed off the ambulance to be transported to the hospital, the compression lever can be extended to perform CPR while pushing the transfer bed.

[0010] The fastener is used to fasten onto the first side rail of the medical transfer bed.

[0011] A medical transfer bed, characterized by having a cardiac compression device as described in any one of the above.

[0012] The reason for describing the relationship between the compression lever and the medical transfer bed as "the vertical distance between the lower end of the compression head and the surface of the medical transfer bed is that when in use, the patient lies on the surface of the medical transfer bed, and the average chest thickness of an ordinary person is about 20 centimeters. Therefore, "the vertical distance between the lower end of the compression head and the surface of the medical transfer bed is 20 centimeters" is equivalent to the situation where the compression head is pressed on the chest of an ordinary patient.

[0013] The term "longitudinal" refers to the length of the transfer bed, which is the direction of the patient's height after lying down; the term "transverse" refers to the horizontal direction perpendicular to the longitudinal direction.

[0014] The term "first horizontal side" can refer to either the left or right side; when the first horizontal side refers to the left side, the second horizontal side refers to the right side; when the first horizontal side refers to the right side, the second horizontal side refers to the left side.

[0015] The phrase "pressing the lever protrudes beyond the outer edge of the second horizontal side of the medical transfer bed" means that the horizontal projection of the pressing lever protrudes beyond the outer edge of the second horizontal side of the medical transfer bed. When the second horizontal side of the transfer bed refers to the left side edge of the transfer bed, then "outer side" means the left side. When the second horizontal side of the medical transfer bed refers to the right side edge of the transfer bed, then "outer side" means the right side.

[0016] Floating poles are strip-shaped components. Because they move up and down during use, they are called "floating".

[0017] This utility model has the following advantages and effects:

[0018] 1. When a patient experiences cardiac arrest during transport, the cardiopulmonary resuscitation (CPR) device can be attached to the edge of the medical transfer bed using fasteners. Since the CPR lever protrudes more than 8 cm beyond the second horizontal edge of the transfer bed, medical staff can quickly move forward alongside the bed while simultaneously gripping the lever's handles and swinging it up and down to perform CPR. During this process, the medical staff's body orientation can be the same as the direction of travel of the transfer bed, making the CPR posture quite easy and natural. In other words, if the horizontal projection of the CPR lever's handle does not protrude sufficiently beyond the transfer bed, the medical staff's body orientation must be perpendicular to the length of the transfer bed (i.e., the direction of travel). Otherwise, it will be difficult to grip the lever simultaneously and swing it significantly; and if the medical staff's body orientation is perpendicular to the direction of travel, it will be difficult to move forward quickly and synchronously with the transfer bed.

[0019] Second, it is small in size and light in weight, making it easy to pick up, install and disassemble. The pressing process can be made easier by using the lever principle.

[0020] Third, since the pressing process involves rapid walking, it is difficult to accurately control the pressing depth by relying solely on eye-hand coordination. The floating upright of this utility model can cooperate with the second side edge of the medical transfer bed to limit the downward swing of the pressing swing arm, thereby controlling the pressing depth and making the pressing depth accurate, especially preventing the patient's ribs from being fractured due to excessive pressing depth.

[0027] Figure 1 , Figure 2 , Figure 3 As shown, Embodiment 1 of this utility model provides a cardiac compression device for a medical transfer bed, including a compression head 1, a compression swing arm 2, a swing shaft 3, and a shaft seat 4. Both ends of the swing shaft 3 are fastened to the shaft seat 4, and the swing shaft 3 extends longitudinally. The compression swing arm 2 is perpendicularly connected to the swing shaft 3. The compression head 1 is installed in the middle section of the compression swing arm 2. The lateral position of the compression head 1 can be finely adjusted by sliding along the compression swing arm 2 and fixed by bolts 11. The swing end of the compression swing arm 2 forms a grip portion 20 for the rescuer to hold. A fastening element 5 is also provided, which can be used to fasten tightly to the longitudinal railing strip 710 of the first lateral side guardrail 71 of the medical transfer bed. The shaft seat 4 is fixedly connected to the fastening element 5, thereby fixing the position of the swing shaft 3 relative to the medical transfer bed. When the fastening element 5 is fastened to the longitudinal railing strip 710 of the first lateral side guardrail 71 of the medical transfer bed, and the vertical distance between the lower end of the compression head 1 and the bed surface of the medical transfer bed (i.e., ...) is... Figure 2 When the vertical distance between A and B is 20 cm, the horizontal projection of the handgrip 20 of the rocker arm protrudes outside the medical transfer bed 7, and the part of the rocker arm 2 protruding from the outer side of the second lateral edge of the medical transfer bed (i.e., Figure 2 and Figure 3 The lateral dimension of the middle CD section is 28 cm, that is, from the horizontal projection position, the pressure lever protrudes 28 cm outside the medical transfer bed.

[0028] Figure 1 , Figure 2 , Figure 3 As shown, a floating upright 6 is also provided. The upper end of the floating upright 6 is fixedly connected to the pressing swing arm 2. The floating upright 6 swings up and down around the swing axis 3 along with the pressing swing arm 2. The upper end of the floating upright (i.e., Figure 1 , Figure 2 The lateral position of point E is located at the end point of the swing arm (i.e., Figure 1 , Figure 2 Between point D and the pressing head 1, the lateral position of the floating upright 6 is matched with the second lateral side edge frame 72 of the medical transfer bed, so that the second lateral side edge frame 72 of the medical transfer bed can limit the downward movement of the floating upright 6; that is, when the floating upright 6 swings downward around the pendulum axis 3 with the pressing swing arm to a certain extent, the second lateral side edge frame 72 of the medical transfer bed blocks the floating upright 6 from continuing to move downward, thereby controlling the pressing depth.

[0029] The cardiac compression device described in Embodiment 1 is used in a medical transfer bed. Figure 2 , Figure 3 The medical transfer bed equipped with this cardiac compression device shown is also within the protection scope and embodiment of this utility model. When using the aforementioned medical transfer bed, the fastener 5 is fastened to the longitudinal railing 710 of the first transverse side guardrail 71 of the medical transfer bed, thereby fixing the axle seat 4 and the swing shaft 3 to the first transverse side edge of the medical transfer bed. The rescuer stands on the second transverse side of the medical transfer bed, facing the direction of movement of the medical transfer bed, and while quickly following the transfer bed forward, grasps the handle of the compression swing arm and swings it up and down to perform cardiac compressions on the patient. Figure 4 , Figure 5 As shown. After pressing is completed, the fastener 5 can be released, so that the fastener 5 is detached from the longitudinal railing 710 of the first transverse side guardrail 71 of the medical transfer bed, and the entire heart compressor can then be removed from the medical transfer bed.

[0030] In the above embodiments, when the fastener 5 is fastened to the first side railing 71 of the transfer bed and the vertical distance between the lower end of the pressing head 1 and the bed surface of the medical transfer bed is 20 cm, the horizontal dimension of the pressing swing rod 2 protruding from the outer side of the second side edge of the medical transfer bed can be changed to 9 cm, 15 cm or 38 cm. Example 2

[0031] The difference between Embodiment 2 and Embodiment 1 is that the length of the pressing lever 2 in Embodiment 2 is telescopic; that is, the pressing lever 2 in Embodiment 2 is a telescopic lever, including an outer sleeve section 21 and an inner core section 22. The inner core section 22 and the outer sleeve section 21 are connected in an inner-outer loop. The outer diameter of the inner core section 22 is smaller than that of the outer sleeve section 21, allowing it to retract into the outer sleeve section 21. Figure 6 As shown; when the inner core section 22 of the pressing lever is pulled out from the outer sleeve section 21 of the pressing lever, the inner core section 22 of the pressing lever serves as the grip part of the pressing lever; when the fastener 5 of the cardiac compression device in Embodiment 2 is fastened to the longitudinal railing strip 710 of the first side railing 71 of the transfer bed, the vertical distance between the lower end of the pressing head and the bed surface of the medical transfer bed is 20 cm, and the pressing lever 2 is in the state of maximum extension (that is, the length of the inner core section 22 of the pressing lever extending from the outer sleeve section 21 of the pressing lever reaches the maximum value), the horizontal projection position of the grip part of the pressing lever is exposed outside the medical transfer bed 7, and the lateral dimension of the part of the pressing lever 2 exposed outside the medical transfer bed is 32 cm, that is, the horizontal projection position of the pressing lever is exposed 32 cm outside the medical transfer bed.

[0032] The remaining aspects of the structure of Example 2 are the same as those of Example 1.
