Description

Technical Field

[0001] The utility model relates to the technical field of emergency department nursing, in particular to a stretcher with a shock-absorbing structure. Background Art

[0002] Emergency department nursing is the provision of nursing services to patients in urgent need of medical assistance in the emergency department. A stretcher is a medical device used to transport sick or injured people. Stretchers are usually used in emergency rescue, transporting patients to hospitals or intra-hospital transfers, etc. In emergency department nursing, stretchers are an important tool for transporting and transferring emergency patients.

[0003] According to the announcement number: CN217510723U, a stretcher for emergency department nursing includes a support rod and a support surface; the support rod is provided with two groups, and the two sides of the support surface are sleeved on the outside of the two groups of support rods, and the support rods are provided with support connection mechanisms at the positions near both ends; the support connection mechanism includes a baffle, a connecting cavity, a connecting groove, a fixing pin, a locking assembly, a limit groove, a limit block, a connecting plate, a sleeve block, a sleeve groove and a connecting spring, the baffle is provided at the positions near the two ends of the support rod, and the side of the baffle close to the support rod is inserted into the inside of the connecting cavity, the connecting cavity is opened at the positions near the two ends of the support rod, the connecting groove is opened on the side of the baffle close to the support rod, and one side of the fixing pin is inserted into the inside of the connecting groove, and the function of supporting the patient's head or feet is realized through the support connection mechanism.

[0004] In the process of implementing this utility model, the applicant found that there are at least the following problems in the prior art:

[0005] 1. When two medical staff lift the stretcher and walk, they need to concentrate on coordinating the movements of carrying the stretcher. In addition, the medical staff at the back are blocked by the stretcher itself, which increases the difficulty for the medical staff to observe the road conditions ahead and cannot obtain the road conditions ahead in time. The medical staff may not be able to detect the uneven terrain under their feet in time due to unstable center of gravity or obstructed vision, and may accidentally step on stones or depressions. In this case, it is easy to cause falls or sprains, which will bring additional risks and injuries to both medical staff and patients.

[0006] 2. When the stretcher is placed on the ground and in contact with the ground, the vibration from the ground will be directly transmitted to the stretcher, and the patient will directly feel the vibration, which may cause discomfort or even injury. In order to minimize the vibration to the patient, medical staff usually take corresponding measures, such as placing mats or other cushioning materials between the stretcher and the ground to reduce the impact of ground vibration on the patient's body. This can help protect the patient from unnecessary vibration injuries, but medical staff are required to take additional protective measures each time, making the stretcher inconvenient to use. Utility Model Content

[0007] In view of the deficiencies of the prior art, the utility model provides a stretcher with a shock-absorbing structure, aiming to solve the problems of emergency nursing stretchers in the prior art.

[0008] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0009] A stretcher with a shock-absorbing structure, comprising:

[0010] A stretcher bar and a carrying cloth are the main body of the stretcher with a shock absorbing structure, and two stretcher bars are provided;

[0011] Two reinforcement bars are fixed between the two stretcher bars;

[0012] An adjustment plate is sleeved on one of the reinforcement rods;

[0013] A curved mirror is fixedly arranged on the outer surface of the adjustment plate;

[0014] Buffer seats are fixedly arranged on the top and bottom of the two stretcher bars;

[0015] The outer surface of the buffer seat is provided with expansion slots all around.

[0016] Preferably, the adjustment plate is rotatably connected to the reinforcement rod, and a damping pad for increasing friction is arranged in the middle of the adjustment plate.

[0017] Preferably, the buffer seat is arranged in a truncated cone shape and is made of rubber.

[0018] Preferably, the two reinforcement rods are made of stainless steel, and both ends of the two reinforcement rods penetrate into the interior of the stretcher rod.

[0019] Preferably, shoulder straps are fixedly provided at both ends of the two reinforcement rods, and the shoulder straps are made of nylon with good tensile strength and durability.

[0020] Preferably, both ends of the two stretcher rods are fixedly provided with anti-slip handles, and the outer surfaces of the anti-slip handles are evenly distributed with anti-slip patterns.

[0021] Preferably, the carrying cloth is fixedly arranged between the two stretcher poles, and the carrying cloth is made of polyester cloth with good durability, tensile strength and waterproof performance.

[0022] The utility model provides a stretcher with a shock absorbing structure, which has the following features:

[0023] Beneficial effects:

[0024] By setting up an adjustment plate and a curved mirror, when carrying a stretcher, the light from the ground road conditions blocked by the stretcher will be refracted through the curved surface of the curved mirror to form an enlarged and diffused field of view, allowing the user to clearly observe the ground road conditions in the area blocked by the stretcher, which helps to avoid obstacles in time and improve the safety of transportation. By turning the adjustment plate, the user can change the angle of the curved mirror to better observe the road conditions at different locations, increasing flexibility and applicability.

[0025] By providing a buffer seat and an expansion slot, when the stretcher is placed on the ground, the buffer seat contacts the ground, and the rubber material can undergo a certain deformation and generate elasticity, thereby absorbing part of the impact force. In addition, when the buffer seat is subjected to pressure, the rubber material will expand slightly outward under the action of the expansion slot. Such a design can further increase the ability of the buffer seat to absorb and disperse force. The presence of the expansion slot enables the buffer seat to better adapt to impact forces of different shapes and sizes, and provide a more uniform and smooth buffering effect. By using the rubber buffer seat and the expansion slot, the rigid collision force between the stretcher and the ground can be reduced, providing a smoother transportation experience and reducing discomfort to the lifted objects or patients. At the same time, this design also helps to reduce the impact and vibration on the stretcher and the people on it, thereby improving overall safety and comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example: Figure 1-4 As shown, a stretcher with a shock-absorbing structure comprises: a stretcher bar 1 adopts a straight shape to support the structure and load of the entire stretcher, a carrying cloth 2 is located between the two stretcher bars 1, and adopts a shape similar to a flat grid. It has a sufficient area to carry the lifted objects or patients and disperse the weight to reduce the pressure on the stretcher bars 1. The carrying cloth 2 is made of polyester cloth. The polyester cloth has good durability, tensile strength and waterproof performance. This material can withstand a certain tension during use and maintain stability and durability. The carrying cloth 2 is fixedly arranged between the two stretcher bars 1. The specific installation method can use straps, buckles, hooks or other fixing methods to ensure that the connection between the carrying cloth 2 and the stretcher bars 1 is firm and reliable. Anti-slip handles 3 are fixedly arranged at both ends of the two stretcher bars 1. The anti-slip handles 3 are cylindrical in shape. They are designed with a curve suitable for human hand holding to provide a comfortable holding experience. The anti-slip handles 3 are made of a material with an anti-slip function, such as rubber or silicone. This material has good anti-slip performance, can provide a stable grip during transportation, and reduce hand slippage.

[0034] In this embodiment: the reinforcing rod 4 is in a straight line shape and needs to have sufficient rigidity and stability to strengthen the connection between the two stretcher bars 1 and enhance the firmness of the entire stretcher structure. The reinforcing rod 4 is made of stainless steel, which has good corrosion resistance and durability and can withstand certain pressure and stress during transportation, ensuring that the reinforcing rod 4 has sufficient strength and durability. The two ends of the reinforcing rod 4 penetrate the interior of the stretcher bar 1 to ensure that the connection between the reinforcing rod 4 and the stretcher bar 1 is firm and reliable. The shoulder strap 5 is in a belt shape and can be put on the arms of the carrier when the stretcher is lifted to reduce the load on the shoulders and provide more stable support. The length and width of the shoulder strap 5 can be designed according to ergonomic principles to provide a comfortable use experience. The shoulder strap 5 is made of nylon material with good tensile strength and durability. Nylon has the characteristics of lightness, flexibility and wear resistance. It can withstand certain tension and maintain good performance during transportation. The two ends of the shoulder strap 5 are fixedly set at the two ends of the reinforcing rod 4 to ensure that the connection between the shoulder strap and the reinforcing rod is firm and reliable.

[0035] Such structures cooperate with each other. By setting the reinforcement rod 4, the firmness between the two stretcher rods 1 can be enhanced, and the stability and carrying capacity of the entire stretcher structure can be improved. Putting the shoulder strap 5 on the arm can make the porter more labor-saving and stable when lifting the stretcher, and reduce the load on the shoulder, which not only enhances the stability and firmness of the stretcher, but also improves the comfort and efficiency of carrying.

[0036] In this embodiment: the adjustment plate 6 is a semicircular plate, and the adjustment plate 6 is made of solid metal materials, such as steel or aluminum alloy, to ensure sufficient strength and durability. These materials can withstand the stress and load during transportation and have good corrosion resistance. The shape of the curved mirror 8 is a convex mirror, presenting an outward curved surface, and its curvature can be adjusted according to design requirements to obtain the required field of view and refraction effect. The curved mirror 8 is made of optical glass or a special reflective coating. These materials have good optical properties and can ensure the refraction and reflection effects of light, so that the user can clearly observe the ground road conditions in the stretcher shielding area. The outer surface of the adjustment plate 6 is fixedly provided with a curved mirror 8, and the curved mirror 8 can be fixed to the adjustment plate 6 by screws, welding or other fixing methods. At the same time, the adjustment plate 6 is rotatably connected to the reinforcement rod 4, and the rotation can be achieved by bearings, pins or other rotating connection methods. By rotating the adjustment plate 6, the user can change the angle of the curved mirror 8 to better observe the road conditions at different positions. The setting of the damping pad can increase the friction, so that the adjustment plate 6 has a certain damping effect when rotating, providing appropriate stability and controllability.

[0037] Such structures cooperate with each other to provide an enlarged and diffused field of view through the refraction effect of the curved mirror 8, allowing the user to clearly observe the ground road conditions in the stretcher shielding area. The user can change the angle of the curved mirror 8 by rotating the adjustment plate 6 to adapt to road conditions in different locations, thereby increasing flexibility and applicability. At the same time, the setting of the damping pad can provide stable rotation and controllability, thereby improving safety during transportation.

[0038] In this embodiment: the buffer seat 7 is truncated cone-shaped and is made of rubber material. It can be made of rubber material to ensure a certain elasticity and shock absorption performance. The expansion groove 9 is a groove opened around the outer surface of the buffer seat 7. The function of the expansion groove 9 is to enable the buffer seat 7 to expand slightly outward when subjected to pressure, thereby further increasing the ability of the buffer seat to absorb and disperse force.

[0039] Such structures can achieve the following effects by cooperating with each other:

[0040] Absorbing impact force: The buffer seat 7 is made of rubber, which has certain elasticity and shock absorption performance, can absorb part of the impact force, reduce the impact on the stretcher and the lifted objects or patients, and provide a more comfortable transportation experience;

[0041] Adapt to impact forces of different shapes and sizes: The presence of the expansion slot 9 enables the buffer seat to better adapt to impact forces of different shapes and sizes, providing a more uniform and stable buffering effect;

[0042] The combined design of the buffer seat 7 and the expansion slot 9 can reduce the rigid collision force, provide a smooth transportation experience, and reduce the discomfort to the lifted objects or patients. At the same time, this design also helps to reduce the impact and vibration on the stretcher and the people on it, thereby improving overall safety and comfort.

[0043] Working principle: When the user lifts the stretcher through the non-slip handle 3, the shoulder strap 5 can be put on the arm of the carrier to reduce the load on the shoulder and provide more stable support. Later, when carrying the stretcher, the light of the ground road conditions blocked by the stretcher will be refracted through the curved surface of the arc mirror 8 to form an enlarged and diffused field of view, allowing the user to clearly observe the ground road conditions in the area blocked by the stretcher, which helps to avoid obstacles in time and improve the safety of transportation. When the stretcher is placed on the ground, the buffer seat 7 is in contact with the ground, and the rubber material can undergo a certain deformation and produce elasticity, thereby absorbing part of the impact force. In addition, when the buffer seat 7 is under pressure, the rubber material will expand slightly outward under the action of the expansion slot 9. Such a design can further increase the ability of the buffer seat 7 to absorb and disperse force, reduce the rigid collision force between the stretcher and the ground, provide a smoother transportation experience, and reduce the discomfort to the lifted objects or patients. It also helps to reduce the impact and vibration on the stretcher and the people on it, thereby improving overall safety and comfort.
