Description

Technical Field

[0001] This utility model relates to the field of stretcher technology, specifically to a rescue stretcher. Background Technology

[0002] Currently, the nursing stretchers used in the emergency department are mainly composed of stretcher poles and canvas, and the structure is relatively simple. In order to improve the efficiency of rescue, medical staff will perform cardiopulmonary resuscitation on the corresponding patients during the movement. However, when medical staff squeeze on the load-bearing frame to perform CPR on the patient, on the one hand, the patient's limbs are squeezed, and on the other hand, the medical staff are prone to falling off the stretcher.

[0003] In the prior art, stretcher carts reduce the possibility of patients falling off the device by setting up side armrests. However, when the operator lifts the patient onto the device, the armrests can easily obstruct the operator, and the device is also quite high, making it a troublesome process to lift the patient onto the device.

[0004] This utility model proposes a rescue stretcher to solve the problems that when the operator lifts the patient onto the device, the handrail can easily obstruct the operator, and the device is quite high, making it difficult to lift the patient onto the device. Utility Model Content

[0005] The purpose of this invention is to overcome the problems in the prior art where the handrails can easily obstruct the operator when the operator lifts the patient onto the device, and the device is also quite high, making it difficult to lift the patient onto the device.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0007] A rescue stretcher vehicle includes an adjustable base and a reclining board mounted on top thereon. A plurality of positioning mechanisms are provided between the adjustable base and the reclining board. An adjustable guard is movably mounted on the reclining board. The adjustable guard is connected to the positioning mechanisms by steel cables.

[0008] The adjustable base is used to adjust the height of the reclining board, and the positioning mechanism is used to fix the position of the adjustable base. When the positioning mechanism is in operation, it pulls the adjustable support frame to move via a steel cable.

[0009] Further defining the above technical solution, the adjustable base includes a base plate and an electric push rod. The electric push rod is fixedly mounted on the top of the base plate, and the extended end of the electric push rod is fixedly connected to the bottom surface of the reclining board. The electric push rod is used to adjust the height of the reclining board.

[0010] Further defining the above technical solution, the bottom of the base plate is provided with two roller rods, and the top surface of the lying plate is provided with a number of grooves corresponding to the positioning mechanism.

[0011] Further defining the above technical solution, the positioning mechanism includes a hinge plate, a connecting plate, and a rubber plate. The upper end of the hinge plate is hinged to the bottom surface of the lying plate, and the lower end of the hinge plate is hinged to the top surface of the connecting plate. The connecting plate is movably disposed within the slide groove, and the rubber plate is fixedly disposed at one end of the connecting plate that passes through the slide groove. The rubber plate is used to restrict the rolling of the roller rod.

[0012] As a further limitation of the above technical solution, the width of the connecting plate is smaller than the width of the hinge plate and the rubber plate.

[0013] As a further limitation of the above technical solution, a first baffle is fixedly installed at both the left and right ends of the top surface of the lying board.

[0014] Further defining the above technical solution, the top surface of the reclining board is provided with a storage groove corresponding to the adjustable baffle. The adjustable baffle includes a second baffle and several springs. The second baffle is movably inserted into the storage groove, and the second baffle is connected to the inner wall of the storage groove through several springs.

[0015] Further defining the above technical solution, one end of the steel cable is fixedly connected to the inner side of the second stop, and the other end of the steel cable passes through the lying plate and is fixedly connected to the side wall of the hinge plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The device is more convenient to use: when the bed is lowered, it causes the positioning mechanism to move and limit the adjustable base, so as to fix the position of the device. As the positioning mechanism moves, the traction cable moves synchronously, and then the adjustable guardrail is lowered by the cable, so that the operator can lift the patient onto the bed.

[0018] To reduce the possibility of patients falling: When the hinge plate resets, it causes the steel cable to lose tension. At this time, the spring pushes the second stop to reset, thereby limiting and blocking the patient through the cooperation of the second stop and the first stop, so as to reduce the possibility of the patient rolling off the bed.

[0024] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0025] Example 1: This example provides a rescue stretcher vehicle, such as... Figure 1 As shown, it can solve the problem that when the operator lifts the patient onto the device, the handrail can easily obstruct the operator, and the device is relatively high, making it difficult to lift the patient onto the device. It includes an adjustable base 1 and a reclining board 2 set on top of it. Several positioning mechanisms 3 are set between the adjustable base 1 and the reclining board 2. An adjustable baffle 4 is movably set on the reclining board 2. The adjustable baffle 4 and the positioning mechanisms 3 are connected by steel cables 5.

[0026] The adjustable base 1 is used to adjust the height of the reclining plate 2, and the positioning mechanism 3 is used to fix the position of the adjustable base 1. When the positioning mechanism 3 is running, it pulls the adjustable baffle 4 to move through the steel cable 5.

[0027] The adjustable base 1 facilitates the adjustment of the height of the reclining board 2. When the reclining board 2 moves down, it causes the positioning mechanism 3 to move and limit the adjustable base 1, so as to fix the position of the device. As the positioning mechanism 3 moves, the traction cable 5 moves synchronously. Then, the adjustable baffle 4 is pulled down by the cable 5 so that the operator can lift the patient onto the reclining board 2.

[0028] Combination Figure 2 , Figure 3 In an embodiment of this utility model, the adjustable base 1 includes a base plate 11 and an electric push rod 12. The electric push rod 12 is fixedly mounted on the top of the base plate 11. The extended end of the electric push rod 12 is fixedly connected to the bottom surface of the reclining board 2. The electric push rod 12 is used to adjust the height of the reclining board 2. The height of the reclining board 2 can be easily adjusted by the electric push rod 12. When the reclining board 2 is lowered, it is convenient for the operator to lift the patient onto the reclining board 2.

[0029] Combination Figure 2 , Figure 3 The bottom of the base plate 11 is provided with two roller rods 13, and the top surface of the lying plate 2 is provided with a number of sliding grooves 14 corresponding to the positioning mechanism 3. The roller rods 13 facilitate the operator to move the position of the device, and the sliding grooves 14 facilitate the positioning mechanism 3 to be limited.

[0030] Example 2: Reference Figure 2 , Figure 3 The positioning mechanism 3 includes a hinge plate 31, a connecting plate 32, and a rubber plate 33. The upper end of the hinge plate 31 is hinged to the bottom surface of the lying board 2, and the lower end of the hinge plate 31 is hinged to the top surface of the connecting plate 32. The connecting plate 32 is movably disposed in the slide groove 14, and the rubber plate 33 is fixedly disposed at one end of the connecting plate 32 that passes through the slide groove 14. The rubber plate 33 is used to restrict the rolling of the roller rod 13. When the lying board 2 moves down, the hinge plate 31 is folded, and then the connecting plate 32 and the rubber plate 33 are pushed to move through the hinge plate 31, thereby causing the rubber plate 33 to come into contact with the roller rod 13, and thus positioning the roller rod 13 to achieve the positioning of the device, thereby reducing the possibility of the device position constantly changing when the operator lifts the patient onto the lying board 2. When the lying board 2 is reset, the connecting plate 32 and the rubber plate 33 are pulled back to reset through the hinge plate 31, thereby causing the rubber plate 33 to separate from the roller rod 13. At this time, the operator can directly push the device to move.

[0031] The width of the connecting plate 32 is smaller than the width of the hinge plate 31 and the rubber plate 33. The connecting plate 32 cooperates with the slide groove 14 so that when the hinge plate 31 deflects, it can push the connecting plate 32 and the rubber plate 33 to move.

[0032] Example 3: Reference Figure 2 The top surface of the lying board 2 is fixedly equipped with a first baffle 21 at both the left and right ends, which facilitates the restriction and blocking of the patient's head and legs.

[0033] The top surface of the reclining board 2 is provided with a storage groove 22 corresponding to the adjustable baffle 4. The adjustable baffle 4 includes a second baffle 41 and several springs 42. The second baffle 41 is movably inserted into the storage groove 22. The second baffle 41 is connected to the inner wall of the storage groove 22 through several springs 42. The storage groove 22 facilitates the storage of the second baffle 41. When the hinge plate 31 pushes the connecting plate 32 to move, it pulls the steel cable 5 to move. Then, the steel cable 5 pulls the second baffle 41 into the storage groove 22 and causes the springs 42 to compress and deform. When the hinge plate 31 returns to its original position, it causes the steel cable 5 to lose tension. At this time, the springs 42 push the second baffle 41 to return to its original position. Thus, the second baffle 41 and the first baffle 21 work together to limit and block the patient, thereby reducing the possibility of the patient rolling off the reclining board 2.

[0034] One end of the steel cable 5 is fixedly connected to the inner side of the second baffle 41, and the other end of the steel cable 5 passes through the reclining board 2 and is fixedly connected to the side wall of the hinge plate 31. The steel cable 5 controls the movement of the second baffle 41 when the hinge plate 31 is deflected. When the second baffle 41 is retracted into the storage slot 22, it is convenient for the operator to lift the patient onto the reclining board 2.

[0035] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
