Description

Technical Field

[0001] This utility model relates to the field of emergency nursing technology, specifically to an emergency nursing transport device. Background Technology

[0002] In emergency nursing care, patient triage is crucial to ensure patients receive appropriate treatment at the right time and in the right area. This often requires the use of transport devices to move patients to beds or examination tables. For example, in patent publication number "CN214129089U" entitled "A Transport Device for Emergency Department Nursing," during patient transport, the patient is lifted onto a bed frame, and the outer protective panel is rotated to the top of the bed board, perpendicular to the bed board plane. The staff then tightens the threaded sleeve downwards, with the bottom of the threaded sleeve contacting the bed board surface. Because the diameter of the threaded sleeve is larger than the width of the U-shaped groove, the threaded sleeve and the bed board plane are perpendicular to each other. The threaded sleeve is threadedly connected to the outer protective panel support. This design ensures the outer protective panel is perpendicular to the bed board, preventing lateral swaying under any circumstances thanks to the threaded sleeve. Medical staff pull the handle, disengaging the push-pull rod from the through-hole and aligning the limiting block at the top of the push-pull rod with the limiting hole on the side of the bed board. The staff then pushes the fixing sleeve to the threaded end of the push-pull rod and rotates it towards the limiting hole, fixing the position of the push-pull rod and facilitating push-pull operations. During transport, the use of shock-absorbing springs fixed to the top of the casters effectively reduces the risk of injury to patients from uneven ground. However, the above structure still has the following problems in actual use:

[0003] Although the above structure effectively reduces the harm to patients caused by uneven ground by fixing shock-absorbing springs to the top of the casters, when transferring patients, multiple people need to lift the patient onto the bed frame. Due to the weight, the lifting process may cause the patient to lose strength, resulting in the patient falling onto the bed frame. This can easily cause secondary injury to patients with external or internal injuries, thereby aggravating the patient's condition.

[0004] Therefore, we proposed that emergency nursing transport devices can effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an emergency nursing transport device to solve the problem mentioned in the background art that, due to the weight of the patient, the lifting process may cause the patient to lose strength, resulting in the patient falling onto the bed frame, which can easily cause secondary injury to patients with external or internal injuries, thereby aggravating the patient's condition.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an emergency nursing transport device, comprising a base and a movable bracket fixed to the lower end of the base for supporting the base;

[0007] It also includes: a roller is installed at the lower end of the mobile bracket, and a servo motor is bolted to the left side of the base. The output end of the servo motor is fixed to one end of the rotating shaft, and the other end of the rotating shaft extends into the base and is connected to the base bearing.

[0008] A gear is fixed to the outside of the rotating shaft, and a transfer mechanism is provided above the gear, which can transfer patients by moving the transfer bed board.

[0009] Preferably, the transfer mechanism includes toothed blocks and a transfer bed plate, wherein the toothed blocks are evenly distributed on the lower end surface of the transfer bed plate, and the transfer bed plate is embedded in the upper end surface of the base.

[0010] Preferably, auxiliary sliders are fixed on both sides of the transfer bed board, and the auxiliary sliders are slidably connected to the base.

[0011] Preferably, the lower end of the transfer bed board is fixedly equipped with auxiliary rollers, and three sets of auxiliary rollers are provided, with the lower end of the auxiliary rollers contacting the base.

[0012] Preferably, the upper surface of the base is provided with a guardrail, and the outer sides of both ends of the guardrail are fixed with limiting slide rods, and the limiting slide rods and the connecting parts are slidably connected.

[0013] Preferably, the connector has a groove inside, and the connector and the base form a rotating connection structure.

[0014] Preferably, the lower ends of both sides of the guardrail are provided with locking holes, and the locking holes and locking rods form a locking connection. The locking rods are disposed between the connecting parts, and the lower ends of the locking rods are fixed to the base.

[0015] Preferably, the four corners of the movable support are equipped with manual telescopic rods, and two sets of electric telescopic rods are symmetrically installed inside the middle of the movable support. The upper part of the electric telescopic rods is connected to the bottom surface of the base.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: This emergency nursing transport device not only eliminates the need for significant lifting of the patient's body, reducing the workload of medical staff, but also avoids the problem of secondary injury to the patient caused by loss of strength during lifting, resulting in the patient falling onto the transfer bed. This improves safety, prevents the guardrails from affecting the operation of the transfer bed, and facilitates the adjustment of the guardrails, saving a significant amount of time. The specific details are as follows:

[0017] 1. Simply lift the patient slightly so that the transfer bed can be moved underneath the patient, and then gently put the patient down. This eliminates the need to lift the patient's body significantly, reducing the workload of medical staff and preventing secondary injuries caused by the patient falling onto the transfer bed due to exhaustion during lifting, thus improving safety.

[0018] The servo motor drives the rotating shaft to rotate, which in turn drives the gear to rotate. Through the rotation of the gear and the meshing connection between the gear and the gear block, the entire transfer bed board moves onto the hospital bed. At the same time, during the movement, auxiliary rollers can be used to help the transfer bed board to move more smoothly.

[0019] The servo motor drives the rotating shaft to reverse, which in turn drives the gear to reverse as well. The gear then drives the transfer bed plate to move onto the base through the tooth block, making it easier to move the patient onto the transport device for transfer.

[0020] 2. Manually lift the guardrail upwards to separate the locking holes and locking rods at the lower ends of both sides of the guardrail, thereby releasing the guardrail from its limiting position. Once the guardrail is no longer restricted, it can rotate on its own, making it easier to remove the obstruction function of the guardrail. At this time, the transfer bed board can slide towards the base, which can prevent the guardrail from affecting the operation of the transfer bed board, and also makes it easier to adjust the guardrail, saving a lot of time.

[0021] By rotating the guardrail to a vertical position and then pressing it down, the locking holes at the lower ends of both sides of the guardrail will engage with the locking rod, thus achieving a limiting and locking effect. The guardrail can effectively block the patient, preventing the patient from falling off the transport device and achieving a protective function. Attached Figure Description

[0030] 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.

[0031] Please see Figures 1-7 The present invention provides the following technical solution:

[0032] Example 1: To address the issue in existing technologies where weight can cause loss of strength during lifting, leading to the patient falling onto the bed frame and potentially causing secondary injury to patients with external or internal injuries, thus worsening their condition, the following solution is disclosed: A base 1 and a movable support 2 fixed to the lower end of the base 1 for support; the movable support 2 also includes rollers mounted on its lower end, and a servo motor 3 bolted to the left side of the base 1, with the output end of the servo motor 3 fixed to one end of a rotating shaft 4, and the other end of the rotating shaft 4 extending to the bottom. The seat 1 is internally connected to the base 1 by a bearing; a gear 5 is fixed on the outside of the rotating shaft 4, and a transfer mechanism is set above the gear 5. The transfer mechanism is used to transfer patients by moving the transfer bed board 7. The transfer mechanism includes toothed blocks 6 and the transfer bed board 7. The toothed blocks 6 are evenly distributed on the lower end surface of the transfer bed board 7, and the transfer bed board 7 is embedded in the upper end surface of the base 1. Auxiliary sliders 8 are fixed on both sides of the transfer bed board 7, and the auxiliary sliders 8 and the base 1 are slidably connected. An auxiliary roller 9 is fixedly installed at the lower end of the transfer bed board 7, and three sets of auxiliary rollers 9 are provided. The lower end of the auxiliary rollers 9 is in contact with the base 1.

[0033] First, the entire transport device is moved parallel to the hospital bed. Then, the servo motor 3 is activated, driving the rotating shaft 4 to rotate. This rotation of the shaft 4 causes the gear 5 to rotate as well. Through the meshing connection between the gear 5 and the gear block 6, the transfer bed board 7 moves onto the hospital bed. During this movement, the auxiliary rollers 9 assist in translating the transfer bed board 7 more smoothly. At this point, the patient is slightly lifted so that the transfer bed board 7 can be moved under the patient. Then, the patient is gently lowered. The servo motor 3 drives the rotating shaft 4 to reverse, causing the shaft 4 to drive the gear 5 to reverse as well. This causes the gear 5 to move the transfer bed board 7 onto the base 1 via the gear block 6, facilitating the transfer of the patient onto the transport device. This eliminates the need for significant lifting of the patient, reducing the workload of medical staff and preventing secondary injuries caused by the patient falling onto the transfer bed board 7 due to loss of strength during lifting, thus improving safety.

[0034] Example 2: Based on Example 1, a new technical solution is added, which facilitates the adjustment of guardrail 10 and saves a lot of time. See details for further information. Figures 1-2 and Figures 5-6 The upper surface of the base 1 is provided with a guardrail 10, and the outer sides of both ends of the guardrail 10 are fixed with limit slide rods 11. The limit slide rods 11 and the connector 12 are slidably connected. The connector 12 has a sliding groove inside, and the connector 12 and the base 1 are rotatably connected.

[0035] Before starting the servo motor 3, the guardrail 10 can be manually raised, thereby separating the locking holes 14 and locking rods 13 at the lower ends of both sides of the guardrail 10, thus releasing the restriction on the guardrail 10. At this time, the limiting slide rod 11 will slide upward in the slide groove of the connecting piece 12. Through the rotational connection formed between the connecting piece 12 and the base 1, the guardrail 10 can rotate on its own after it is no longer restricted, thus facilitating the release of the obstruction function of the guardrail 10. At this time, the transfer bed board 7 can slide towards the base 1, which can prevent the guardrail 10 from affecting the operation of the transfer bed board 7, and also facilitate the adjustment of the guardrail 10, saving a lot of time.

[0036] Example 3: Based on Example 2, a new technical solution is added to prevent the patient from falling off the transport device, thus achieving a protective function. See details below. Figure 1 and Figures 5-6 The guardrail 10 has locking holes 14 at the lower ends of both sides, and the locking holes 14 and the locking rod 13 form a locking connection. The locking rod 13 is located between the connectors 12, and the lower end of the locking rod 13 is fixed to the base 1.

[0037] Furthermore, after transferring the patient to the transfer bed board 7, the guardrail 10 can be manually rotated to a vertical position. Then, by pressing down on the guardrail 10, the guardrail 10 drives the limiting slide rod 11 to slide downward in the slide groove in the connector 12. At this time, the locking holes 14 at the lower ends of both sides of the guardrail 10 will form a locking connection with the locking rod 13, thereby achieving the effect of limiting locking. The guardrail 10 can effectively block the patient, thereby preventing the patient from falling off the transfer device and achieving the protective function. Finally, the patient can be transferred by moving the rollers at the lower end of the support 2.

[0038] Example 4: Based on Example 1, a new technical solution is added to adjust the height of the support base 1 inside the emergency nursing transport device. This allows the entire emergency nursing transport device to adapt to hospital beds or operating tables of different heights, meeting various usage needs. The four corners of the movable support 2 are equipped with manually telescopic rods, and two sets of electrically operated telescopic rods 15 are symmetrically installed inside the middle of the movable support 2. The upper part of the electrically operated telescopic rods 15 is connected to the bottom surface of the base 1. For the specific structure, please refer to the attached diagram. Figure 7 As shown, when the height of the base 1 needs to be adjusted, the electric telescopic rod 15 is activated. The output end of the electric telescopic rod 15 drives the base 1 and the transfer bed board 7 to move upward together. At this time, the manual telescopic rod structure at the four corners of the moving bracket 2 is pulled and extended, thereby ensuring that the base 1 and the transfer bed board 7 rise stably. When the base 1 and the transfer bed board 7 rise to the height corresponding to the hospital bed or operating table, the electric telescopic rod 15 is stopped. At this time, the lowest point of the transfer bed board 7 is higher than the highest point of the hospital bed or operating table, so that it is convenient to move the transfer bed board 7 above the hospital bed or operating table later, so that the patient can be placed on the transfer bed board 7. The operation is convenient and can meet different usage needs.

[0039] Meanwhile, the rollers installed at the lower end of the movable bracket 2 have a braking function, so that the position of the movable bracket 2 can be fixed after it has moved by the rollers themselves, so as to prevent the movable bracket 2 from being moved by the rollers due to external forces. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
