DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4 The quick translation butt joint device for the stretcher vehicle and the emergency rescue bed provided in the embodiments of the present application comprises a stretcher vehicle 1. The stretcher vehicle 1 is in a rectangular structure. A guardrail 11 is installed on the left side of the upper end of the stretcher vehicle 1. Handle frames 12 are symmetrically installed on the front and rear ends of the stretcher vehicle 1. Turnover frames 13 are symmetrically installed on the lower end of the stretcher vehicle 1 through a pin shaft. Universal wheels 14 are installed on the lower end of the turnover frames 13.

[0024] Please refer to Figures 1-4 As shown in the figure, a rectangular opening is formed in the middle of the upper end of the stretcher vehicle 1. A translation butt joint assembly 2 is fixedly installed in the rectangular opening. The height of the translation butt joint assembly 2 is higher than the height of the rescue bed.

[0025] In the above technical solution, the patient transported to the hospital by the stretcher vehicle 1 needs to be quickly transferred to the rescue bed for subsequent rescue. Currently, the patient is usually directly transferred by personnel. However, this transfer method is easy to cause secondary injury to the patient. The translation butt joint assembly 2 can directly transfer the patient to the rescue bed, without causing secondary injury to the patient, and can reduce the workload of medical staff and improve the convenience of use.

[0026] Please refer to Figures 2-4As shown in the preferred technical solution of the present embodiment, the translation docking assembly 2 comprises a horizontal translation unit 21 and a translation bed frame 22, the horizontal translation unit 21 is installed inside the rectangular opening, and the translation bed frame 22 is installed at the upper end of the horizontal translation unit 21. The horizontal translation unit 21 can drive the translation bed frame 22 to reciprocate.

[0027] In the above technical solution, the patient lies on the translation bed frame 22 after being injured. When it is necessary to transfer the patient to a rescue bed, the stretcher 1 is aligned with one side of the rescue bed, and the universal wheel 14 is locked to prevent the stretcher 1 from moving. Then, the translation bed frame 22 drives the patient to translate to one side of the rescue bed. Since the height of the translation bed frame 22 is higher than that of the rescue bed, the translation bed frame 22 can accurately drive the patient to move directly above the rescue bed. The medical staff supports the patient with their arms, and the translation bed frame 22 is pulled back to complete the accurate translation and transfer process of the patient.

[0028] Referring to Figure 2 As shown in the preferred technical solution of the present embodiment, the horizontal translation unit 21 comprises a crossbeam 211, guide rails 212, a sliding block 213, and a piston push rod 214. The crossbeam 211 is fixedly installed on the right side of the rectangular opening. The guide rails 212 are installed between the crossbeam 211 and the stretcher 1 at uniform intervals. The sliding block 213 is slidably arranged on the guide rail 212. The sliding block 213 is fixedly connected to the left lower end of the translation bed frame 22. The guide rail 212 has a hollow structure. The piston push rod 214 is slidably arranged in the guide rail 212. The piston push rod 214 is fixedly connected to the right end of the translation bed frame 22.

[0029] In the above technical solution, a hydraulic system is installed on the stretcher 1. The hydraulic system is connected to the inside of the guide rail 212. When it is necessary to drive the translation bed frame 22 to horizontally translate, the hydraulic system injects liquid into the inside of the guide rail 212. The piston push rod 214 drives one end of the translation bed frame 22 to move to the right. The other end of the translation bed frame 22 slides on the outside of the guide rail 212 through the sliding block 213. This can facilitate the horizontal movement of the translation bed frame 22 and ensure the stability of the translation bed frame 22, preventing the translation bed frame 22 from tilting. After the translation of the patient is completed, the hydraulic system drives the translation bed frame 22 to reset through the piston push rod 214.

[0030] Referring to Figures 1-2 As shown in the preferred technical solution of the present embodiment, the translation bed frame 22 has a rectangular structure. The translation bed frame 22 is a steel skeleton structure. The upper end surface of the translation bed frame 22 is a flexible structure. The translation bed frame 22 is provided with an arc-shaped groove 221 at the upper end. The translation bed frame 22 is uniformly provided with a bandage 222 at the upper end surface.

[0031] In the above technical solution, the steel skeleton structure of the translation bed frame 22 has high strength, thereby ensuring the safety of the patient during movement, the arc-shaped groove 221 can facilitate the patient to lie down, and the binding belt 222 can tighten the chest and waist of the patient, thereby avoiding the phenomenon of tilting of the patient during movement or translation, and preventing the patient from falling and causing secondary injury.

[0032] Referring to Figures 1-2 As shown in the preferred technical solution of the present embodiment, the inner concave surface of the arc-shaped groove 221 is uniformly provided with an air bag cushion 223.

[0033] In the above technical solution, when the translation bed frame 22 drives the patient to move to the position directly above the rescue bed, the air bag cushion 223 is inflated, so that the air bag cushion 223 can lift the back of the patient, and a gap is formed between the side edge of the air bag cushion 223 and the body of the patient, which facilitates the arms of medical staff to be inserted to support the patient, thereby improving the safety of patient transfer.

[0034] The working principle of the present application is as follows: S1: initial preparation and positioning and fixing The stretcher 1 carrying the patient is pushed to one side of the emergency rescue bed, and the stretcher 1 is aligned with the rescue bed along the long side direction, then the universal wheel 14 at the bottom of the stretcher 1 is locked to prevent the stretcher 1 from moving during the transfer process, and to ensure the stability of the docking process.

[0035] S2: start translation, patient horizontal translation The hydraulic system on the stretcher 1 is started, liquid is injected into the cavity inside the guide rail 212, and the piston push rod 214 is pushed out; the piston push rod 214 drives the right end (close to the side of the rescue bed) of the translation bed frame 22 to move horizontally to the right, while the left end of the translation bed frame 22 slides synchronously on the outer side of the guide rail 212, in this process, the patient moves horizontally with the translation bed frame 2, until the patient's body is completely moved to the position directly above the rescue bed.

[0036] S3: air bag lifting and personnel receiving When the patient is translated to the position above the rescue bed, the air bag cushion 223 in the arc-shaped groove 221 of the translation bed frame 2 is inflated, and the air bag cushion 223 is inflated to slightly lift the back of the patient, so that a sufficient gap is formed between the patient's body and the bed surface, which facilitates the medical staff to insert their arms under the patient's body to support and receive the patient.

[0037] S4: bed frame withdrawal and transfer completion After the medical staff's arms support the patient stably, the hydraulic system works in reverse, the piston push rod 214 is retracted, the translation bed frame 2 is separated from the patient and returns to the initial position on the stretcher 1, and the patient is safely placed on the rescue bed by the medical staff, thereby completing the entire translation and transfer process.

[0038] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
