Description

Technical Field

[0001] The present invention relates to the field of medical first-aid equipment, and particularly to a medical stretcher for first-aid use. Background Art

[0002] A stretcher is a commonly used medical device, especially in the field of emergency. Generally, it is used in conjunction with an ambulance. Existing stretchers have a bracket and a support pad for patients to lie flat. Existing stretchers can accommodate most patients. However, for patients with burns or scalds, although they can be used, during the use process, the on-board doctor cannot perform preliminary treatment on the burn or scald patients. As is well known, for burn or scald patients, generally, the burned or scalded area needs to be soaked or rinsed with cold water, and after preliminary treatment, they are sent to the hospital. In this way, better treatment can be provided to the patients. However, preliminary treatment requires treatment time and treatment conditions. Especially outdoors, in the case of being scalded by the road surface due to a fall, more time is required for preliminary treatment. If the on-board doctor performs treatment first and then places the patient in the ambulance for rescue, it will delay the treatment time. Therefore, there is an urgent need to design a rescue device that does not delay the progress of the ambulance and can facilitate the on-board doctor to perform preliminary cold water treatment on burn or scald patients. Summary of the Invention

[0003] The purpose of the present invention is to provide a medical stretcher for first-aid use. Through the design of the medical stretcher, it can cooperate with a water storage frame filled with cold water in the ambulance, and can soak and rinse the burned or scalded area of the patient in the medical stretcher with cold water during the progress of the ambulance, without delaying the treatment time while performing preliminary treatment on the patient.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: a medical stretcher for first-aid use, including a bracket, on which a stretcher frame composed of four side plates and a bottom plate is provided. Water pipe installation screw holes are opened on two opposite side plates, and a water inlet pipe and a water outlet pipe are respectively fitted on the two water pipe installation screw holes. An inlet water channel matched with the water inlet pipe and an outlet water channel matched with the water outlet pipe are opened in the bottom plate. The inlet water channel extends into the side plate and is communicated with a sprinkler arranged on the inner side surface of the side plate. A water outlet groove is opened on the inner bottom surface of the bottom plate, and the water outlet groove is communicated with the outlet water channel.

[0005] Preferably, the bottom plate is in the middle of the four side plates and divides the stretcher frame composed of the four side plates into two stretcher cavities. The sprinkler is located in one of the stretcher cavities. A pin hole is opened on the side plate matched with the bracket, and this side plate is connected to the bracket through a structure in which a locking pin is matched with the pin hole. Both the water inlet pipe and the water outlet pipe pass through the part where the bracket is matched with the corresponding side plate.

[0006] Preferably, cylindrical support rods are evenly arranged in the stretcher cavity where the sprinkler is installed. A support pad for the patient to lie flat is provided on the support rods. The distance between the support pad and the bottom plate (3) is 10 - 16 cm. The sprinkler is higher than the support pad, and there is a gap of 2 - 10 cm between the support pad and the side plate.

[0007] Preferably, the support pad includes a square ring-shaped pad frame and a pad mesh at the center of the pad frame. The pad frame and the pad mesh are provided with water-permeable soft pads.

[0008] Preferably, pad frame mounting posts are provided below the pad frame, and pad frame mounting sleeves that are sleeved and matched with the pad frame mounting posts are provided on the bottom plate.

[0009] Preferably, the sprinkler includes a sprinkler mounting rod arranged on the inner side of the side plate and a sprinkler water supply pipe communicated with the water inlet channel. The sprinkler mounting rod is connected with a nozzle through a universal joint. The nozzle is communicated with a nozzle water supply pipe through a hose, and a switching valve is matched with the nozzle water supply pipe.

[0010] Preferably, a handle groove is provided on the outer side of the side plate where a pin hole is opened. A pullable handle block is provided in the handle groove. A handle center groove is opened at the center of the handle block. A handle mating insertion block that is matched with the handle center groove of the pulled-out handle block is provided on the support.

[0011] Preferably, the handle block is a stepped block. The end at the inner side of the handle groove is the part with a larger size. The handle groove is a stepped groove, and the part at the outer side of the side plate is a small-size groove. The large-size groove of the handle groove is matched with the large-size end of the handle block, and the small-size groove of the handle groove is larger than the small-size end of the handle block.

[0012] Preferably, a concave filter screen with an open upper end is provided in the water outlet groove. A molecular filter membrane that can only pass water molecules is wrapped outside the filter screen.

[0013] Preferably, the upper end of the filter screen is lower than the inner bottom surface of the bottom plate, and the upper ends of the four sides of the filter screen are inclined downward inward.

[0014] The technical effects of the present invention are as follows:

[0015] 1. Through the design of the medical stretcher, it can cooperate with the water storage frame filled with cold water in the ambulance, and can soak and rinse the scalded parts of the patients in the medical stretcher during the ambulance's travel, providing preliminary treatment for the patients without delaying the treatment time.

[0016] 2. The design of the side plate and the bottom plate forming two stretcher cavities can not only be adapted for use by burn patients, but also be converted into a common stretcher mode, facilitating overall use.

[0017] 3. The design of the height of the support pad and the gap with the side can ensure that the patient on the support pad can be partially immersed in the water in this stretcher cavity, and at the same time ensure that the water sprayed by the sprinkler can enter the support pad, facilitating the circulation treatment of the cooling water.

[0018] 4. The structural design of the support pad, using the cooperation of the pad mesh and the permeable soft pad, can make the support pad have good water permeability and can more effectively partially immerse the patient. The structural design of the pad frame mounting posts and the pad frame mounting sleeves can ensure that the pad blocks will not move significantly.

[0019] 5. The design of the sprinkler can realize the adjustment of the spraying direction, and then can perform concentrated cold water spraying treatment according to the scalded part of the patient.

[0020] 6. The design of the handle block and the handle groove can facilitate the conversion and installation of the stretcher frame, and the cooperation between the handle center groove and the handle mating insert can play a preliminary positioning effect on the stretcher frame, thus facilitating the installation of the locking pin. The stepped design of the handle block and the handle groove can not only realize the pulling out of the handle block, but also prevent the handle block from being completely pulled out.

[0021] 7. The design of the filter screen and the molecular filter membrane can intercept and collect the tissue fragments of the burned part after the patient is immersed, thereby ensuring the cleanliness of the recycled water liquid, and can also collect the burned tissue and conduct subsequent tests.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0030] As Figure 1 shown, the structure of the present invention is: a medical stretcher for first aid, including a support 1, and a stretcher frame composed of four side plates 2 and a bottom plate 3 is arranged on the support 1. Water pipe mounting screw holes 25 are opened on two opposite side plates 2, and a water inlet pipe 5 and a water outlet pipe 6 are respectively fitted on the two water pipe mounting screw holes 25. A water inlet channel 7 matching the water inlet pipe 5 and a water outlet channel 8 matching the water outlet pipe 6 are opened in the bottom plate 3. The water inlet channel 7 extends into the side plate 2 and communicates with a sprinkler 9 arranged on the inner side surface of the side plate 2. A water outlet trough 10 is opened on the inner bottom surface of the bottom plate 3, and the water outlet trough 10 communicates with the water outlet channel 8.

[0031] The specific operation is as follows: Set a water tank on the ambulance, and set a water pump and a refrigeration structure in the water tank. When the medical stretcher of the present invention is used together with the water tank of the ambulance, when used for first aid of burn or scald patients, the patient is carried into the ambulance through the medical stretcher, and then the water inlet pipe 5 and the water outlet pipe 6 are connected to the water tank. Then, cold water is sent into the water inlet pipe 5 through the water pump in the water tank, and then enters the water inlet channel 7 and is sprayed onto the scalded area of the patient in the stretcher through the sprinkler 9. At the beginning, the water pump connected to the water outlet pipe 6 is in a closed state, so the water sprayed by the sprinkler 9 will remain in the stretcher frame and soak the burn or scald area of the patient. When the water reaches a certain depth, the doctor on the vehicle opens the water pump connected to the water outlet pipe 6, and then the water level in the stretcher frame can be maintained at a level suitable for the patient to soak. The spraying of the sprinkler 9 and the water outlet of the water outlet pipe 6 reach a dynamic balance. In this way, cold water flushing and soaking treatment can be carried out on the patient during the ambulance journey, achieving preliminary treatment without delaying the time for first aid transportation.

[0032] As Figures 1-3As shown, the bottom plate 3 is in the middle of the four side plates 2 and divides the stretcher frame formed by the four side plates 2 into two stretcher cavities. The sprinkler 9 is located in one of the stretcher cavities. A pin hole 26 is formed on the side plate 2 that cooperates with the bracket 1, and this side plate 2 is connected to the bracket 1 through a structure in which a locking pin 4 cooperates with the pin hole 26. Both the water inlet pipe 5 and the water outlet pipe 6 pass through the part where the bracket 1 cooperates with the corresponding side plate 2.

[0033] The bottom plate and the side plates form two stretcher cavities. When treating burn patients, the stretcher cavity with the sprinkler 9 is turned upwards. Then, the locking pin 4 is passed through the bracket 1 and inserted into the pin hole 26. Then, the water inlet pipe 5 and the water outlet pipe 6 are passed through the bracket 1 and threadedly sleeved into the water pipe installation screw holes 25. In this way, the fixation of the stretcher frame is achieved. When treating ordinary patients, the other stretcher cavity is turned upwards and locked in the same way. The pin hole 26 is symmetric about the horizontal plane where the center line of the water pipe installation screw hole is located, which can ensure that the stretcher frame can be fixed through the locking pin 4, the water inlet pipe 5, and the water outlet pipe 6 after conversion.

[0034] As Figure 1 and Figure 2 shown, cylindrical support rods 11 are evenly arranged in the stretcher cavity where the sprinkler 9 is installed. A support pad 12 for the patient to lie flat is arranged on the support rod 11. The distance between the support pad 12 and the bottom plate 3 is 10 - 16 cm. The sprinkler 9 is higher than the support pad 12. There is a gap of 2 - 10 cm between the support pad 12 and the side plate 2. The support pad 12 includes a square ring-shaped pad frame 15 and a pad net 16 at the center of the pad frame 15. Permeable soft pads 17 are arranged on the pad frame 15 and the pad net 16. A pad frame installation column 18 is arranged below the pad frame 15. A pad frame installation sleeve 19 that is sleeved and matched with the pad frame installation column 18 is arranged on the bottom plate 3.

[0035] When treating burn patients, the support pad 12 is placed on the support rod 11. Specifically, the pad frame installation column 18 is inserted into the pad frame installation sleeve 19. In this way, the installation and fixation of the entire support pad 12 can be achieved. With the design of the pad net 16 and the permeable soft pads 17 on the support pad 12, a good water flow effect can be achieved.

[0036] As Figure 6 shown, the sprinkler 9 includes a sprinkler installation rod 31 arranged on the inner side of the side plate 2 and a sprinkler water supply pipe 34 communicated with the water inlet channel 7. The sprinkler installation rod 31 is connected with a spray head 33 through a universal joint 32. The spray head 33 is communicated with the spray head water supply pipe 34 through a hose, and a switch valve 35 is matched with the spray head water supply pipe 34.

[0037] The sprayer 9 is switched on and off through the switch valve 35, so that the corresponding sprayer 9 can be opened according to the patient's part, and the nozzle 33 can also adjust the spraying angle through the universal joint, and the on-vehicle doctor can perform accurate cold water flushing operations.

[0038] As Figures 1-4 shown, a handle groove 21 is provided on the outer side of the side plate 2 provided with a pin hole 26. A pullable handle block 22 is provided in the handle groove 21. A handle center groove 24 is provided at the center of the handle block 22. A handle mating plug 23 is provided on the bracket 1 and is matched with the handle center groove 24 of the pulled-out handle block 22; the handle block 22 is a stepped block, and the end at the inner side of the handle groove 21 is the part with a larger size. The handle groove 21 is a stepped groove, and the part at the outer side of the side plate 2 is a small-size groove. The large-size groove of the handle groove 21 is matched with the large-size end of the handle block 22, and the small-size groove of the handle groove 21 is larger than the small-size end of the handle block 22.

[0039] When placing the stretcher frame, first pull out the upper handle block 22 from the handle groove 21, and then socket and match the handle center groove 24 of the handle block 22 with the handle mating plug 23 on the bracket 1, so as to realize the preliminary positioning and support of the stretcher frame. After that, through the installation of the locking pin 4 and the locking jack 25, and then the installation of the water inlet pipe 5 and the water outlet pipe 6, the installation and fixation of the stretcher frame can be realized. The operation is simple. The handle block 22 can not only play the role of convenient picking and placing, but also play the role of preliminary positioning and facilitate the subsequent assembly of the stretcher frame.

[0040] As Figure 5 shown, a concave filter screen 29 with an open upper end is provided in the water outlet groove 10. A molecular filter membrane 28 that can only pass water molecules is wrapped outside the filter screen 29; the upper end of the filter screen 29 is lower than the inner bottom surface of the bottom plate 3, and the upper ends of the four sides of the filter screen 29 are inclined inward and downward.

[0041] The water liquid in the bottom plate 3 will first enter the water outlet groove 10. After being filtered by the filter screen 29 and the molecular filter membrane 28, the water molecules will enter the water outlet channel 8, and then enter the water tank through the water outlet pipe 6 for recycling. The molecular filter membrane 28 is arranged outside the filter screen 29, so that too much burn tissue debris can be avoided from adhering to the molecular filter membrane, which is convenient for cleaning. Compared with the structure in which the molecular filter membrane 28 is arranged inside the filter screen, the situation of the filter screen being blocked can be avoided. The height of the filter screen and the inclined surface design at the upper end of the filter screen can facilitate the cleaning of the entire bottom plate and the collection of residues.
