Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a foldable multifunctional emergency stretcher. Background Technology

[0002] Stretchers are among the most commonly used first-aid supplies, enabling rapid transport of patients to the emergency site. Currently, there are various types of emergency stretchers. Some stretchers are manually lifted onto the stretcher and then carried away; these stretchers may have wheels, while others require manual carrying. Other stretchers, such as scoop stretchers, do not require manual lifting onto the stretcher but still need to be carried away manually. Each type of stretcher has its advantages and disadvantages. For example, the former type has a larger surface area, allowing for better placement of the patient and improving comfort during transport. However, this type of stretcher requires manual lifting of the patient, which is more strenuous. Furthermore, some patients require specific body positioning when being lifted onto the stretcher; they cannot be lifted arbitrarily. For instance, lifting the patient head-to-body level can be cumbersome and inconvenient. While scoop stretchers, due to their scooping mechanism, allow for relatively easy and convenient transfer of patients, their small surface area leaves part of the patient's body suspended, making lying down uncomfortable. Therefore, existing emergency stretchers require further improvement to enhance ease of use and transport comfort. Utility Model Content

[0024] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0025] Please see Figure 1-6 In a preferred embodiment of this utility model, a foldable multifunctional emergency stretcher includes an outer frame 1 composed of two horizontal bars 1.1 and two vertical bars 1.2, and a stretcher fabric 2. The outer frame 1 forms a foldable frame through the vertical bars 1.2 divided into two parts. The stretcher fabric 2 is divided into two pieces, one piece of stretcher fabric 2 is installed on a folding unit of the outer frame 1, and one end of each piece of stretcher fabric 2 is connected to a vertical bar 1.2, while the other end is detachably connected to another vertical bar 1.2. Two movable rods 5 are movably arranged between the two vertical bars 1.2. Each movable rod 5... All rods 5 are foldable rod structures, and both ends of each movable rod 5 are slidably connected to the horizontal bar 1.1 at the corresponding end via a sliding sleeve 6. The sliding sleeve 6 is provided with an operating handle 7, which is located on the outside of the outer frame 1. Each folding unit of each movable rod 5 is rotatably provided with a shovel plate 8. The shovel plate 8 can be placed vertically or horizontally by rotating and folding relative to the movable rod 5. When placed horizontally, the shovel plate 8 is located between the two movable rods 5. When the stretcher cloth 2 is connected to both vertical bars 1.2, it is located at the bottom of the shovel plate 8 and the movable rod 5.

[0026] This invention combines a scoop stretcher with a regular folding stretcher, making it easier for medical staff to transfer patients onto the stretcher and improving patient comfort while lying on it. Specifically, the scoop plate 8 can move along the width of the stretcher's outer frame 1 with the movable rod 5 to open and close the scoop plate 8, effectively lifting and releasing the patient. The detachable stretcher cloth 2 allows for a gap between the two scoop plates 8 before lifting the patient and closes the bottom of the scoop plate 8 after lifting the patient, facilitating the placement of the patient's body and improving comfort during transport.

[0027] In this embodiment, the stretcher cloth 2 is detachably connected as follows: several locking rods 4 are spaced apart on the vertical rod 1.2 detachably connected to the stretcher cloth 2, and several locking rings 3 are provided on the other end of the stretcher cloth 2. Each locking ring 3 matches a locking rod 4. The stretcher cloth 2 is detachably connected to the vertical rod 1.2 by the locking rings 3 engaging the locking rods 4. That is, after slightly lifting the outer frame 1, one end of the locking ring 3 of the stretcher cloth 2 is pulled horizontally from below the shovel plate 8 to one end of the locking rod 4, and then the locking ring 3 is engaged on the locking rod 4. The stretcher cloth 2 is then laid under the shovel plate 8 to provide protection for the patient. Preferably, the locking rod 4 is located at the bottom of the vertical rod 1.2, so that the patient will not touch the locking rod 4. At this time, after the stretcher cloth 2 is wrapped from the top to the bottom of the vertical rod 1.2, the locking ring 3 is engaged with the locking rod 4 again. In a second embodiment of this invention, the snap-fit ​​rod 4 can be replaced with a ring structure. In this case, the snap ring 3 is a ring-shaped locking structure, thus connecting the stretcher cloth 2 to the vertical rod 1.2 by snapping. Regardless of the detachable connection method, it is preferable to also provide a snap-fit ​​rod 4 on the vertical rod 1.2 that is not detachably connected to the stretcher cloth 2. The snap ring 3 on the stretcher cloth 2 can be detachably connected to any vertical rod 1.2 through the snap-fit ​​rod 4. In this way, the stretcher cloth 2 can be stably set on one vertical rod 1.2 before the shovel 8 lifts the patient, avoiding obstruction of the use of the shovel 8.

[0028] In this invention, the shovel plate 8 is rotatably connected to the movable rod 5. This allows the outer frame 1 to be connected to the shovel plate 8 and placed over the outside of the patient. After placement, the shovel plate 8 can be flipped to a horizontal position to lift the patient. This arrangement allows the shovel plate 8 to be placed on either side of the patient without completely disassembling the stretcher, and the patient can be lifted by the lateral movement of the movable rod 5 on the outer frame 1. Preferably, in this embodiment, the shovel plate 8 is rotatably connected to the movable rod 5 via a rotating cylinder. A limiting strip 10 is provided on the inner wall of the rotating cylinder, and a rotating groove 9 is formed on the wall of the movable rod 5. The limiting strip 10 is movably embedded in the rotating groove 9. When the limiting strip 10 rotates to the groove wall of the rotating groove 9, the shovel plate 8 is placed vertically or horizontally. That is, the limiting strip 10 and the rotating groove 9 ensure that the shovel plate 8 remains in a horizontal position. In addition, to prevent the shovel plate 8 from accidentally moving laterally and opening outward after being scooped up, a locking hole is provided on the crossbar 1.1, and a locking rod (not shown) is provided on the sliding sleeve 6. The locking rod is slidably mounted on the sliding sleeve 6. When the sliding sleeve 6 moves to the point where the locking rod is directly opposite the locking hole (not shown), the locking rod is inserted into the locking hole, and the sliding sleeve 6 can no longer slide on the movable rod 5. Furthermore, a spring is sleeved on the locking rod, and the spring is also connected to the sliding sleeve 6. In the natural state of the spring, the locking rod is inserted into the locking hole when it is directly opposite the locking hole. In this way, when the sliding sleeve 6 moves to the point where the locking rod is directly opposite the locking hole, the locking rod is automatically inserted into the locking hole. When unlocking is required, the locking rod is pulled to disengage it from the locking hole.

[0029] The working principle of this utility model is:

[0030] Before use, the stretcher is in a folded state, with the movable rod 5 positioned close to the vertical rod 1.2, and the stretcher cloth 2 placed on one side of the vertical rod 1.2. In use, unfold the stretcher and rotate the shovel 8 to a vertical position. At this time, the shovels 8 on both sides are located on the left and right sides of the vertical bars 1.2. Lift the stretcher and place the outer frame 1 of the stretcher over the outside of the patient. The shovels 8 and the movable bar 5 are both located on the outside of the patient, so that one side of the shovel 8 (such as the right side shovel 8) is close to the patient, and the other side of the shovel 8 (such as the left side shovel 8) is away from the patient. After the left side shovel 8 is flipped to a horizontal position, pull the stretcher to the right so that the left side shovel 8 is under the patient. Then flip the right side shovel 8 to a horizontal position and pull the stretcher to the left. Since the left side shovel 8 has been pressed under the patient, use the patient's weight to press down the left side shovel 8 or fix the left movable bar 5. When pushing the outer frame 1 to the left, the outer frame 1, together with the right side shovel 8, slides relative to the sliding sleeve 6 on the left movable bar 5. The right side shovel 8 can then be under the patient. At this time, both the left and right shovels 8 are under the patient, and the patient can be transferred. Before transport, you can choose to install a stretcher cloth 2 to protect the patient and facilitate the placement of the patient's body. At this time, you need to lift one end of the stretcher first, loosen the stretcher cloth 2 at that end, and then wrap it around from under the shovel plate 8 to the vertical bar 1.2 on the other side. Connect the retaining ring 3 on the stretcher cloth 2 to the retaining rod 4 on the vertical bar 1.2 on the other side to complete the installation of the stretcher cloth 2. Similarly, install the stretcher cloth 2 at the other end. After the stretcher cloth 2 is installed, the patient can be transported.

[0031] In addition, the stretcher of this utility model can also be equipped with a fixing strap (not shown in the figure). The two ends of the fixing strap are respectively connected to two vertical rods 1.2. The connection between the fixing strap and the vertical rods 1.2 that are detachably connected to the stretcher cloth 2 is a detachable connection. It can be detached by using the connection between the retaining ring 3 and the retaining rod 4. The retaining ring 3 is preferably a ring-shaped locking structure, and the retaining rod 4 is preferably a ring-shaped structure. The tightness of the fixing strap is adjustable.

[0032] Furthermore, in another embodiment of this utility model, a receiving groove (not shown) is provided at the top of the vertical rod 1.2, which is not detachably connected to the stretcher cloth 2. An infusion rod (not shown) is placed within the receiving groove. One end of the infusion rod is rotatably connected to the vertical rod 1.2, and the other end is provided with an infusion hook. The infusion hook is located outside the receiving groove or within the receiving groove due to the rotation of the infusion rod relative to the vertical rod 1.2. That is, with this arrangement, the infusion rod can be removed to suspend the infusion bottle when an infusion is needed for the patient. Preferably, the infusion rod is a telescopic structure.

[0033] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
