Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretcher flatcar technology, specifically a stretcher flatcar that can assist in measurement. Background Technology
[0002] Currently, the stretchers and trolleys installed in hospitals are mainly used for adding beds in wards, and for patients temporarily hospitalized for observation and intravenous infusion in the emergency department. This is to provide patients with a private personal space, ensure their safety and privacy, and also save space and promote hygiene and environmental protection.
[0003] Existing stretcher trolleys designed for rescue use cannot be moved well in uneven environments. Rescue personnel can only transfer the patient or the stretcher trolley as a whole, which is time-consuming and laborious. Moreover, the roller supports are mostly welded to the stretcher trolley, making it impossible to disassemble in special circumstances.
[0004] To overcome the above-mentioned defects, the prior art (application number: CN218529079U, Chinese patent with application date of 2022-08-25) discloses a single-wheel stretcher flatcar for hospitals, including a base, a first support plate, a second support plate, a pillow, a strap, a positioning hole, a connecting sleeve, a docking plate, a lifting rod, an adjusting plate, a limiting plate, a locking plate, a locking sleeve, a damping column, a shock-absorbing spring, and a connecting frame. The beneficial effects of this utility model are as follows: a shock-absorbing spring is nested on the damping column in this device, and the shock-absorbing spring is squeezed and locked between the lock sleeve and the connecting frame. The combination of the damping column and the shock-absorbing spring forms a shock-absorbing structure, which avoids excessive vibration amplitude when the stretcher flatcar moves, thus preventing secondary injury to the wounded. The top of the lock sleeve in this device is provided with a rectangular cavity in an inward concave shape, and slots are provided on the front and rear side walls of the lock sleeve. The slots are connected to the cavity. Locking plates are elastically connected to the front and rear side walls of the limiting plate by springs, so that rescuers can quickly separate the limiting plate and the lock sleeve by pressing the locking plates, and thus the base can be quickly disassembled and used separately.
[0005] While existing technologies can solve the above problems, the design of the rotation assistance for stretchers and trolleys is too complicated. It cannot effectively assist patients in sitting up when they are unable to move independently or have difficulty moving. Moreover, most of the measurement designs for patients in existing technologies require the patient's cooperation, which wastes manpower and the measurement results are not accurate enough. Utility Model Content
[0006] The purpose of this invention is to provide a stretcher trolley that can assist in measurement, in order to solve the problems mentioned in the background art, such as the overly complex rotation assistance design of the stretcher trolley, which cannot effectively assist patients in sitting up when they are unable to move independently or have difficulty moving, and the fact that most of the existing measurement designs for patients require the patient's cooperation, which wastes manpower and the measurement results are not accurate enough.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stretcher flatcar for auxiliary measurement, comprising a movable roller installed below the connecting rod, a rotating soft pad installed above the movable roller, a fixed bed board installed below the rotating soft pad, and the connecting rod being fixedly connected to the fixed bed board; a rotating fixed frame installed above the fixed bed board, and a meshing transmission mechanism for rotating the rotating soft pad installed inside the rotating fixed frame; the meshing transmission mechanism includes a turntable, and a first gear is installed at the center of the turntable; the turntable is installed inside the rotating fixed frame, and a second gear is installed to the right of the first gear; a driven rod is installed inside the fixed support frame, and the first gear is fixedly connected to the driven rod; a movable sliding block is installed at the end of the driven rod, and a limiting sliding frame is installed on the outer surface of the movable sliding block; the limiting sliding frame is installed on the back of the rotating soft pad, and a rotating support frame is installed inside the rotating soft pad;
[0008] A scale support plate is installed above the fixed bed board, and an engagement sliding mechanism for sliding the scale rod up and down is installed inside the scale support plate.
[0009] Furthermore, the meshing sliding mechanism includes a third gear, which is rotatably mounted on the outer surface of the scale support plate. A fourth gear is mounted on the right side of the scale support plate, and the third gear and the fourth gear contact each other to generate meshing motion.
[0010] Furthermore, a transmission belt is installed on the outer surface of the fourth gear, and a scale rod is installed on the left side of the transmission belt. A first inner groove is opened on the surface of the scale support plate, and the scale rod is slidably installed inside the first inner groove. An elastic extension rope is installed on the top of the scale rod, and the elastic extension rope fixing rod is installed on the outer surface of the scale support plate.
[0011] Furthermore, the connecting rod and the movable roller are designed as a single unit, and the connecting rod and the fixed bed board are fixedly installed. Moreover, the outer surface of the turntable and the inner surface of the rotating fixed frame are in contact to form a sliding structure, and the turntable and the first gear are designed as a single unit.
[0012] Furthermore, the outer surface of the first gear contacts the outer surface of the second gear to form a meshing structure, and the turntable forms a transmission structure through the contact between the outer surfaces of the first gear and the second gear. Moreover, the first gear and the driven rod are designed as a single unit.
[0013] Furthermore, the first gear is fixedly connected to the driven rod through the outer surface of the second gear to form a transmission structure, and the movable sliding block is fixedly installed inside the driven rod. Moreover, the inner surface of the limiting sliding frame contacts the outer surface of the movable sliding block to form a sliding structure, and the movable sliding block is fixedly connected to the rotating soft pad through the outer surface of the limiting sliding frame to form a transmission structure.
[0014] Furthermore, the elastic extension rope is fixedly connected to the scale rod, and the outer surface of the third gear and the outer surface of the fourth gear are in contact to form a meshing structure.
[0015] Compared with the prior art, the beneficial effects of this utility model are: the stretcher flatcar that can assist in measurement rotates along the rotating fixed frame turntable, which drives the first gear fixed on the other side to rotate synchronously, and the second gear rotates synchronously due to the meshing connection. The second gear drives the integrated driven rod to move upward along the inside of the fixed support frame, and at the same time the moving sliding block slides along the limiting sliding frame, driving the rotating soft pad to rotate upward along the rotating support frame. This design allows for adjustment to a suitable transport angle when transporting patients.
[0016] Furthermore, when measurement is required, the scale support plate is rotated to keep it level with the fixed bed board. The third gear is rotated, which in turn drives the fourth gear to rotate in a circular motion. The rotation of the fourth gear drives the transmission belt to move continuously, and the movement of the transmission belt contacts the scale rod. The friction causes the scale rod to move downward along the first inner groove until an accurate value is measured. This design makes the measurement operation more convenient. Before surgery, medical staff need to know the patient's weight and height in order to control the dosage of surgical medication, including the anesthetic. Therefore, it can be directly reported and handled in the emergency room. The overall design of the stretcher measurement makes it convenient for some patients who cannot sit up to have their height and weight measured while lying down. The main purpose of measuring height is to facilitate the control of the preoperative anesthesia dosage based on the patient's height and weight.
[0017] Furthermore, as the scale rod slides along the inside of the first inner groove, it drives the elastic extension rope above to extend and lengthen, making the reset of the scale rod more convenient. Moreover, when the rotating pad rotates upward, the rotating telescopic rod also extends with the movement. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figure 1-6 The present invention provides the following technical solution: a stretcher flatcar for auxiliary measurement, comprising a connecting rod 1, a movable roller 2, a fixed support frame 17 and a fourth gear 23.
[0027] A movable roller 2 is installed below the connecting rod 1, and a rotating soft pad 3 is installed above the movable roller 2. A fixed bed board 5 is installed below the rotating soft pad 3, and the connecting rod 1 and the fixed bed board 5 are fixedly connected. A rotating fixed frame 9 is installed above the fixed bed board 5, and a meshing transmission mechanism for rotating the rotating soft pad 3 is installed inside the rotating fixed frame 9. The meshing transmission mechanism includes a turntable 8, and a first gear 15 is installed at the center of the turntable 8. The turntable 8 is installed inside the rotating fixed frame 9, and a second gear 16 is installed on the right side of the first gear 15. A driven rod 18 is installed inside the fixed support frame 17, and the first gear 15 and the driven rod 18 are fixedly connected. A movable sliding block 20 is installed at the end of the driven rod 18, and a limiting sliding frame 19 is installed on the outer surface of the movable sliding block 20. The limiting sliding frame 19 is installed on the back of the rotating soft pad 3, and a rotating support frame 6 is installed inside the rotating soft pad 3.
[0028] A scale support plate 10 is installed above the fixed bed board 5, and an engagement sliding mechanism for sliding the scale rod 13 up and down is installed inside the scale support plate 10.
[0029] like Figure 1 , Figure 3 , Figure 4 The technical solution shown, in order to solve the problem that patients have difficulty getting out of bed or eating, which affects their rest, discloses the following: the connecting rod 1 and the moving roller 2 are integrated into one piece, and the connecting rod 1 and the fixed bed board 5 are fixedly installed. The outer surface of the turntable 8 contacts the inner surface of the rotating fixed frame 9 to form a sliding structure. The turntable 8 and the first gear 15 are integrated into one piece, and the outer surface of the first gear 15 contacts the outer surface of the second gear 16 to form a meshing structure. The turntable 8 forms a transmission structure through the contact between the outer surfaces of the first gear 15 and the second gear 16. The first gear 15 and the driven rod 18 are integrated into one piece, and the first gear 15 is fixedly connected to the driven rod 18 through the outer surface of the second gear 16 to form a transmission structure. The moving sliding block 20 is fixedly installed inside the driven rod 18. The inner surface of the limiting sliding frame 19 contacts the outer surface of the moving sliding block 20 to form a sliding structure. The moving sliding block 20 is fixedly connected to the rotating soft pad 3 through the outer surface of the limiting sliding frame 19 to form a transmission structure.
[0030] When the patient needs to eat or get out of bed, and is unable to move easily, the turntable 8 rotates inside the rotating fixed frame 9. As the turntable 8 rotates, the first gear 15, which is fixed at the center of the turntable 8, rotates synchronously. The first gear 15 is rotatably mounted on the outer surface of the fixed support frame 17. The rotation of the first gear 15 drives the second gear 16 mounted on the side. The first gear 15 and the second gear 16 mesh, causing the second gear 16 to drive the driven rod 18 to swing in a circle inside the fixed support frame 17. The movement of the driven rod 18 drives the movable sliding block 20 mounted inside the driven rod 18 to move synchronously. The movable sliding block 20 slides inside the limiting sliding frame 19 fixed on the back of the rotating soft pad 3 until it reaches a suitable height. The rotating soft pad 3 rotates in a circle along the rotating support frame 6 and finally remains fixed. The patient's lower body is stabilized by the fixed soft pad 4. When the rotating soft pad 3 rotates, the rotating telescopic rods 7 mounted on both sides remain vertical.
[0031] like Figure 2 , Figure 5 , Figure 6The technical solution shown discloses the following to address the inconvenience of measurement operations: A meshing sliding mechanism includes a third gear 22, which is rotatably mounted on the outer surface of a scale support plate 10. A fourth gear 23 is mounted on the right side of the scale support plate 10, and the third gear 22 and the fourth gear 23 mesh with each other. A transmission belt 21 is mounted on the outer surface of the fourth gear 23, and a scale rod 13 is mounted on the left side of the transmission belt 21. A first inner groove 14 is formed on the surface of the scale support plate 10, and the scale rod 13 is slidably mounted inside the first inner groove 14. An elastic extension rope 12 is mounted on the top of the scale rod 13, and a fixing rod of the elastic extension rope 12 is mounted on the outer surface of the scale support plate 10. The elastic extension rope 12 and the scale rod 13 are fixedly connected, and the outer surfaces of the third gear 22 and the fourth gear 23 contact each other to form a meshing structure.
[0032] When measurements of the patient are required, the scale support plate 10, which is rotatably mounted on the side of the fixed bed board 5, is rotated until it is level with the fixed bed board 5 for more accurate measurements. After reaching the horizontal position, the third gear 22 is rotated. The rotation of the third gear 22 drives the fourth gear 23, which is also rotatably mounted on the side of the scale support plate 10 on the right. As the fourth gear 23 rotates, the transmission belt 21 mounted on the outer surface of the fourth gear 23 rotates horizontally. Since the scale rod 13 is in contact with the transmission belt 21, the scale rod 13 is driven by the transmission belt 21 under the action of friction, and pulled to the left along the first inner groove 14. The rod 13 is slidably installed inside the first inner groove 14, so the scale rod 13 slides horizontally to the left in sync. At the same time, the sliding of the scale rod 13 causes the elastic extension rope 12 fixedly installed at the top of the scale rod 13 to extend. When the sliding reaches the measurement position, the rotation stops. When no measurement work is required, the scale support plate 10 can be used to perform water infusion operation by hooking the fixed bed board 5 vertically with the hook 11. The dosage of the medicine before the patient enters the operating room requires the patient to stand and cooperate, which is very wasteful of physical strength. Moreover, patients who are too weak cannot cooperate well, making it difficult to control the dosage of anesthetic. This design speeds up the process of surgery.
