Description

Technical Field

[0001] This utility model relates to the field of safety fixing technology for medical personnel inside ambulances, and in particular to a safety fixing device for use inside medical personnel in ambulances. Background Technology

[0002] Ambulances are specialized vehicles used by medical and health institutions for pre-hospital emergency care, patient transport, emergency rescue, medical support, and the transport of special supplies. They are marked with specific ambulance symbols and equipped with warning lights and alarm systems. The interior is typically divided into a driver's compartment and a medical compartment. The medical compartment is equipped with medicine and medical equipment cabinets, oxygen and infusion systems, and other facilities to meet the needs of emergency care, monitoring, and transport in various scenarios. Medical personnel use safety restraints inside the ambulance, primarily to cope with unpredictable situations such as sudden acceleration, braking, turning, and bumps during vehicle movement, preventing themselves from falling or being injured in collisions. This also ensures the stability and accuracy of emergency procedures such as intravenous puncture and cardiopulmonary resuscitation, ensuring the smooth conduct of emergency care and reducing the risk of secondary injury to patients.

[0003] However, the existing safety restraint devices used in ambulances for medical personnel have the following drawbacks:

[0004] (1) Traditional medical personnel use safety restraint devices in ambulances. The structure is simple. When the ambulance accelerates, brakes, turns and shakes violently, the connecting belt is prone to loosening or rolling back. It cannot provide continuous and stable restraint for medical personnel, causing their bodies to easily shift. Not only do they face the risk of collision and injury, but it also affects the accuracy of emergency operations, such as deviation during intravenous puncture and unstable compression position during cardiopulmonary resuscitation, increasing the possibility of secondary injury to the patient.

[0005] (2) Some traditional medical personnel use safety restraint devices in ambulances. The restraint method is relatively complicated and difficult to remove quickly. When encountering an emergency, when medical personnel need to quickly remove the restraint device to deal with other emergencies, the cumbersome removal steps will become a serious obstacle, greatly delaying precious emergency rescue time and increasing the threat to the patient's life safety.

[0006] Therefore, this utility model provides a safety fixing device for medical personnel to use inside an ambulance. Utility Model Content

[0030] The retraction assembly 2 includes a round rod rotatably connected to one side of the storage box 1. One end of the round rod extends into the interior of the first cavity. A worm gear 201 is fixedly connected to the end of the round rod extending into the first cavity. A rotating block 202 is fixedly connected to the other end of the round rod. A worm wheel 203 meshes with the surface of the worm gear 201. The self-locking characteristic of the transmission between the worm gear 201 and the worm wheel 203 is utilized to ensure that the worm gear 201 will not loosen or rewind due to external forces such as the shaking of the ambulance, thus ensuring the continuous and stable restraint of medical personnel. A rotating rod 204 is fixedly inserted through the center of the worm wheel 203. One end of the rotating rod 204 extends into the interior of the second cavity. A storage cylinder 205 is fixedly sleeved on the surface of the rotating rod 204 for winding the connecting strap 3. The connecting strap 3 is wound and unwound through its own rotation. The surface of the storage cylinder 205 is provided with the connecting strap 3.

[0031] The disassembly assembly 5 includes two fixing blocks 501 fixedly connected to both sides of the waist belt 4. The two fixing blocks 501 are symmetrically arranged, and each fixing block 501 has a strap 502 on its surface. The fixing blocks 501 can firmly fix the strap 502 to the waist belt 4, ensuring that the strap 502 will not fall off during use and ensuring the stability of the overall structure of the disassembly assembly 5. One end of one strap 502 is provided with a buckle female seat 503, and the other end of the strap 502 is provided with a buckle female seat 504.

[0032] Two fixing straps 6 are fixedly connected to one side of the storage box 1. The two fixing straps 6 are symmetrically arranged. The two symmetrically arranged fixing straps 6 fixedly connected to one side of the storage box 1 can securely fix the storage box 1 in a suitable position inside the ambulance.

[0033] The upper surface of the waist belt 4 is fixedly connected to two shoulder straps 7, which can effectively prevent medical personnel from leaning forward, backward or sideways, making their bodies more stable when performing emergency operations that require the use of the whole body, such as cardiopulmonary resuscitation.

[0034] The inner side of the waist belt 4 is provided with a positioning pad 8. The positioning pad 8 is made of memory foam. Memory foam has good plasticity and resilience, and can automatically shape according to the contour of the medical staff's waist, closely fit the waist curve, and reduce the local pressure of the waist belt 4 on the waist.

[0035] The waist belt 4 and the positioning pad 8 have ventilation holes on one side. The ventilation holes are arranged in a linear manner. The ventilation holes can promote air circulation, accelerate the dissipation of heat and moisture, and keep the skin of the waist dry and comfortable.

[0036] The storage box 1 has an output port on one side, which is compatible with the connecting strap 3. It plays a good guiding and limiting role in the extension and retraction of the connecting strap 3. The connecting strap 3 extends or retracts through the output port.

[0037] In this invention, the working steps of the device are as follows:

[0038] First step: When it is necessary to extend the connecting belt 3, the medical staff rotates the rotating block 202, which drives the worm gear 201 to rotate synchronously. The worm gear 201 has a worm wheel 203 meshing on its surface, which drives the worm wheel 203 to rotate. The worm wheel 203 drives the storage cylinder 205 to rotate through the rotating rod 204. As the storage cylinder 205 rotates, the connecting belt 3 wrapped on it is gradually released. The connecting belt 3 extends to the outside through the output port on one side of the storage box 1, thereby extending the length of the connecting belt 3.

[0039] Step 2: When medical staff need to use the equipment for fixation, after the medical staff has fixed the equipment, they take the waist belt 4 and wrap it around the waist from the back. Then they take the straps 502 on both sides and pull them towards the front of the body. One hand holds the end with the buckle female seat 503 and the other hand holds the end with the buckle male seat 504. The protrusion of the buckle male seat 504 is aligned with the groove of the buckle female seat 503, so that the buckle male seat 504 is inserted into the buckle female seat 503. When the holding parts on both sides of the buckle male seat 504 pass through the semi-circular groove of the buckle female seat 503, the two straps 502 are tightly connected together by the buckle structure.
