Technical Field
[0001] The present invention relates to the technical field of medical devices, and particularly to a split-type patient handling cart for cardiovascular medicine that can carry a stretcher. Background Art
[0002] The department of cardiology, that is, cardiovascular medicine, is a clinical department set up by the general internal medicine department of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, acute myocardial infarction and other cardiovascular diseases. A medical stretcher refers to a tool used to carry patients who are not easy to move. The patient can lie on the stretcher and then be carried by medical staff, which is convenient for medical staff to carry injured patients. And the stretcher itself can simply fix the patient to prevent the patient from being secondarily injured during the handling process. Generally, the volume of the stretcher is small, which is convenient for folding and storage and suitable for use in small spaces such as corridors. A handling cart refers to a patient handling device with moving wheels that can move quickly on a flat ground. Generally, it has a large volume and is only suitable for use in broad venues and flat ground. Whether it is a medical stretcher or a handling cart, they are mainly used in emergency situations.
[0003] However, the medical stretchers and handling carts currently used in the market each have certain limitations in use, and it is not convenient to effectively combine the medical stretcher and the handling cart, making it difficult to splice and use. Moreover, the structure of the existing handling cart is difficult to fold and stretch, resulting in a large space occupation during its daily use and storage. For this reason, we propose a split-type patient handling cart for cardiovascular medicine with higher practicability that can carry a stretcher. Summary of the Invention

A male lock end 14 is clamped inside the female lock end 13;
[0028] The cart structure 1 includes side rods 101, card slots 102, a bottom plate 103, and shock pads 104. Card slots 102 are evenly opened on the upper surface of the side rods 101. The bottom plate 103 and the shock pads 104 are welded inside the side rods 101, and the shock pads 104 are located above the bottom plate 103. Moreover, the structure of the shock pads 104 is an elastic structure. It is set that the cart structure 1 is made of two side rods 101 and a bottom plate 103 welded together to form the main part. At the same time, an elastic shock pad 104 is installed above the bottom plate 103. In order to effectively shock-absorb the stretcher structure 10 placed inside the cart structure 1 through the elastic action of the shock pads 104, thereby improving the stability of the stretcher structure 10 during the movement of the entire device, and then enhancing the comfort effect of the patient lying during the transportation process;
[0029] The connecting structure 7 includes a roller 701, a bracket 702, a telescopic rod 703, a spring 704 and a sleeve rod 705. The bracket 702 is hinged to the lower outer side of the roller 701. The telescopic rod 703 is fixed below the bracket 702. The spring 704 is sleeved on the outer side of the telescopic rod 703. The lower part of the telescopic rod 703 is connected to the sleeve rod 705. The size of the roller 701 matches that between the linear guide rail 5 and the concave guide rail 6. The telescopic rod 703 and the sleeve rod 705 cooperate with each other to form a telescopic structure. At the same time, the telescopic rod 703 and the sleeve rod 705 form an elastic structure through the spring 704. The linear guide rail 5 and the concave guide rail 6 are installed on the same track line. Four concave guide rails 6 are symmetrically installed on one linear guide rail 5. The roller 701 in the connecting structure 7 can be embedded in the linear guide rail 5 and the concave guide rail 6 for rolling movement. The telescopic rod 703 can be telescoped inside the sleeve rod 705. The roller 701 can be clamped inside the concave guide rail 6 by the elastic action of the spring 704, so as to fix the lower moving support structure 9 in a relatively contracted or extended state, ensuring the stability of the moving support structure 9 during the working process;
[0030] The moving support structure 9 includes a support rod 901, a connecting rod 902 and a universal wheel 903. The connecting rod 902 passes through the middle position of the support rod 901. The universal wheel 903 is installed at the lower end of the support rod 901. The support rod 901 is symmetric about the vertical center line of the connecting rod 902. The connection mode between the support rod 901 and the connecting rod 902 is a rotational connection. The support rod 901 and the connecting rod 902 cooperate with each other to form an X-shaped structure. The moving support structure 9 is mainly composed of the intersecting support rods 901. The support rod 901 and the connecting rod 902 can rotate. Therefore, the support rods 901 can be folded and contracted, so that when the whole device is not in use, the moving support structure 9 can be folded and contracted, which is beneficial to reducing the volume of the whole device and saving space during storage;
[0031] The stretcher structure 10 includes stretcher longitudinal rods 1001, stretcher cross rods 1002, a traction cloth 1003, clamping blocks 1004, and hinges 1005. The stretcher cross rods 1002 are evenly installed between the inner sides of the stretcher longitudinal rods 1001. The traction cloth 1003 is sleeved between adjacent stretcher cross rods 1002. The clamping blocks 1004 are evenly fixed on the outer sides of the stretcher longitudinal rods 1001. A hinge 1005 is installed at the middle position of the stretcher longitudinal rods 1001. A rotating structure is formed between the stretcher longitudinal rods 1001 and the hinge 1005. The sizes of the clamping blocks 1004 and the clamping grooves 102 match each other. The stretcher structure 10 and the trolley structure 1 form a clamping structure through the clamping blocks 1004 and the clamping grooves 102. Due to the connection of the hinge 1005, the two stretcher longitudinal rods 1001 in the stretcher structure 10 can be folded, so that the entire stretcher structure 10 can be folded in half, which is convenient for taking during first aid. Moreover, the folded stretcher structure 10 is small in volume and occupies little space, which is convenient for storage. The positions of the clamping blocks 1004 installed on the stretcher structure 10 are the same as the positions where the clamping grooves 102 are opened in the trolley structure 1. The clamping blocks 1004 can be inserted into the clamping grooves 102 for fixation, so that the stretcher structure 10 can be spliced with the trolley structure 1 through the clamping action between the clamping blocks 1004 and the clamping grooves 102. The structure is simple and the splicing is convenient. At the same time, when the trolley structure 1 and the stretcher structure 10 are combined and used, the situation of limited use sites when they are used separately is greatly reduced, which is more suitable for use during first aid. The stretcher longitudinal rods 1001 penetrate through the inside of the sliding sleeves 11. A sliding structure is formed by the mutual cooperation between the sliding sleeves 11 and the stretcher longitudinal rods 1001. A clamping structure is formed by the mutual cooperation between the female end 13 of the lock and the male end 14 of the lock. The sliding sleeves 11 are sleeved on the outer sides of the stretcher longitudinal rods 1001 and can move relative to the stretcher longitudinal rods 1001, so as to select a suitable binding position for the patient with the binding belt 12 according to actual needs, which greatly enhances the flexibility during use. The binding belt 12 is connected through the clamping action between the female end 13 of the lock and the male end 14 of the lock, and is more convenient to use.
[0032] Working principle: For this type of split patient handling cart with a stretcher that can be carried in the Department of Cardiovascular Medicine, when it is necessary to handle a patient but the space where the patient is located is small and the cart structure 1 cannot enter, first press down on the cart structure 1 while lifting the stretcher structure 10 upward, so that the block 1004 disengages from the inside of the card slot 102, thereby detaching the stretcher structure 10 from the cart structure 1. By rotating the two ends of the same stretcher longitudinal rod 1001, the stretcher longitudinal rod 1001 can rotate around the hinge 1005, thus folding the stretcher longitudinal rod 1001 in half. Manipulate the two stretcher longitudinal rods 1001 to fold simultaneously, so that the entire stretcher structure 10 is folded up for easy carrying. When reaching the location where the patient is located, first unfold the stretcher structure 10, and at the same time pull the female end 13 and the male end 14 of the lock outward, so that the two are separated. The patient lies on the support surface formed by the traction cloth 1003 and the stretcher cross bar 1002. Then pull the sliding sleeve 11, and the sliding sleeve 11 slides along the stretcher longitudinal rod 1001 to the designated position. Then attach the restraint strap 12 to the patient's body, insert the male end 14 of the lock into the female end 13 of the lock, and use the restraint strap 12 to initially fix the patient.
[0033] By lifting the two stretcher longitudinal rods 1001 upward, the patient can be carried and moved. Then place the stretcher structure 10 carrying the patient above the cart structure 1, so that the position of the block 1004 corresponds to that of the card slot 102. Then insert the block 1004 into the inside of the card slot 102. At this time, the stretcher longitudinal rod 1001 leans against the inside of the side rod 101, and at the same time the support surface formed by the traction cloth 1003 and the stretcher cross bar 1002 is attached above the bottom plate 103 and the shock pad 104. Then pass the binding strap 3 around the patient's upper body, so that the binding strap 3 is attached to the patient. Then stick the round fluff sticker 4 tightly to the prickly fluff sticker 2 for secondary fixation. Push the cart structure 1, move the support structure 9 and the connection structure 7 to support the cart structure 1, and the universal wheels 903 roll on the ground, then the entire device can be driven to move.
[0034] When it is necessary to fold and store the mobile support structure 9, pull the two rollers 701 to both sides. The rollers 701 move along the track from the recessed guide rail 6 in the middle to the linear guide rail 5. At the same time, since the height from the recessed guide rail 6 to the linear guide rail 5 will decrease, during the rotation of the rollers 701 inside the bracket 702, the telescopic rod 703 will be compressed downward. The telescopic rod 703 moves downward and retracts into the sleeve rod 705. At the same time, the spring 704 will be compressed and in a shortened state. When the two rollers 701 separate, the upper and lower ends of the two support rods 901 will be driven to expand. And during the expansion process of the support rod 901, rotations will occur between the support rod 901 and the rotating shaft 8 and the connecting rod 902 until the two rollers 701 move into the two recessed guide rails 6 on the outer side. The telescopic rod 703 will extend from the inside of the sleeve rod 705 under the elastic action of the spring 704, and then drive the rollers 701 to tightly press against the recessed guide rail 6. In this way, the use process of the split-type patient handling cart of the cardiovascular medicine stretcher is completed.
[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
