DETAILED DESCRIPTION
[0023] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, wherein the same components are represented by the same reference numerals.
[0024] See also Figures 1 to 5 The embodiment of the utility model discloses a medical transfer bed, including a movable base 10, a lifting mechanism, a bed board 30, a first elastic telescopic structure 50 and a second elastic telescopic structure 60.
[0025] like Figure 1 As shown, the bottom fixed end of the lifting mechanism is fixed on the top surface of the mobile base 10, and the top lifting end of the lifting mechanism is fixed on the bottom surface of the bed board 30, as shown in FIG. Figure 5 As shown, specifically, the lifting mechanism includes a lifting drive column 21 and four lifting guide rods 22. The lifting guide rod 22 is preferably a spring telescopic rod 52, and its bottom fixed end is arranged at the center position of the bottom surface of the mobile base 10. The four lifting guide rods 22 are preferably spring telescopic rods, and the bottom fixed ends of the four lifting guide rods 22 are arranged at the corners of the top surface of the mobile base 10. It should be noted that the pneumatic telescopic rod and the spring telescopic rod 52 are both purchased parts, and the specific structure will not be repeated.
[0026] like Figure 1 and Figure 3 As shown, a rectangular slot 31 is provided on the top surface of the bed board 30, and the front and rear side walls of the rectangular slot 31 are respectively provided with a first elastic telescopic structure 50 that is telescopic along the length direction of the bed board 30. Figure 4 As shown, each first elastic telescopic structure 50 includes a pressure plate 51 and a plurality of spring telescopic rods 52 arranged in parallel and at intervals. The telescopic end of each spring telescopic rod 52 is fixed to the side wall of the pressure plate 51 away from the mattress 40, and the fixed end of each spring telescopic rod 52 is fixed to the side wall of the rectangular slot 31. More specifically, the front and rear side walls of the rectangular slot 31 are respectively provided with insertion holes corresponding to the spring telescopic rods 52, and the fixed ends of the spring telescopic rods 52 are correspondingly inserted into the insertion holes.
[0027] In this embodiment, there are three spring telescopic rods 52 in a single first elastic telescopic structure 50, and the fixed ends of the three spring telescopic rods 52 are all inserted into corresponding sockets (not exposed to water in the figure) to quickly install the first elastic telescopic structure 50. The telescopic ends of the spring telescopic rods 52 can be fixed to the pressure plate 51 in a common manner (such as threaded connection or clamping, etc.). The height of the pressure plate 51 is lower than the height of the mattress 40, so that the pressure plate 51 can be prevented from extending out of the rectangular slot 31. At the same time, there is a gap of 2-3 mm between the side end of the pressure plate 51 and the side wall of the rectangular slot 31 to prevent unnecessary resistance from being generated between the side wall of the rectangular slot 31 and the end of the pressure plate 51.
[0028] like Figure 1As shown, the left and right side walls of the rectangular slot 31 are respectively fixed with a second elastic telescopic structure 60 that is telescopic along the width direction of the bed board 30 and is located between the two first elastic telescopic structures 50. The second elastic telescopic structure 60 is a strip rubber pad. The two first elastic telescopic structures 50 and the two second elastic telescopic structures 60 form a mattress placement cavity in the rectangular slot 31.
[0029] When the medical transfer bed disclosed in the embodiment of the utility model is in use, the front and rear sides of the mattress 40 respectively abut against the first elastic telescopic structure 50, and the left and right sides of the mattress 40 respectively abut against the second elastic telescopic structure 60. When the speed of the medical transfer bed changes dramatically, or when it travels on an uneven road surface, or even encounters a collision object, due to the provision of the first elastic telescopic structure 50 and the second elastic telescopic structure 60, the mattress 40 will be subjected to a buffering force in the opposite direction to the inertial force, thereby reducing the patient's forward or backward movement due to inertia, thereby ensuring the patient's safety to a certain extent and significantly reducing the risk of injury to the patient due to unexpected situations during the transfer process.
[0030] like Figure 2 As shown, when the mattress 40 is placed in the mattress placement cavity, the telescopic springs in the spring telescopic rods 52 are in a weakly compressed state. That is, when the mattress 40 is placed in the rectangular slot 31, the telescopic springs in the two spring telescopic rods 52 are in a weakly compressed state, which can appropriately improve the stability of the mattress 40. The maximum compression length of the spring telescopic rod 52 is 30 mm, and when in a weakly compressed state, its compression length is 10 mm.
[0031] like Figure 1 and Figure 5 As shown, in the present embodiment, a storage bin 70 located between the lifting drive column 21 and the lifting guide rod 22 is provided on the top surface of the movable base 10. There may be multiple storage bins 70, and corresponding classification labels are provided, such as a first aid supplies storage bin, a doctor supplies storage cavity, a patient personal supplies storage cavity, etc. A window 71 is provided on the upper part of the side wall of the storage bin 70 near the edge of the bed board 30, and a baffle 72 is formed on the lower part, which not only facilitates the taking and placing of articles, but also effectively prevents the articles in the storage bin 70 from shaking and being thrown out due to the movement of the transfer vehicle, and also ensures that the normal use of the storage bin 70 will not be interfered with when the bed board 30 is raised or lowered.
[0032] It should be noted that when the bed board 30 is lowered to the lowest position, a gap of 50-100 mm is still maintained between the top surface of the storage bin 70 and the bottom surface of the bed board 30 to ensure that the normal use of the storage bin 70 is not affected during the lifting and lowering of the bed board 30.
[0033] The medical transfer bed disclosed in the utility model can effectively reduce the patient's forward or backward movement due to inertia during the transfer process by setting the first elastic telescopic structure and the second elastic telescopic structure, thereby ensuring the patient's safety and reducing the risk of accidental injury to the patient. In addition, a storage bin is provided to facilitate the placement of items and prevent items from shaking and falling out, while ensuring that the bed board does not interfere with the use of the storage bin when it is raised or lowered.
[0034] The technical solution of the utility model is described in detail above in combination with specific embodiments, and the described specific embodiments are used to help understand the concept of the utility model. Derivations and variations made by those skilled in the art based on the specific embodiments of the utility model also fall within the protection scope of the utility model.
