Description

Technical Field

[0001] The invention relates to a special rewarming stretcher for hypothermia caused by drowning in seawater, in particular to a special rewarming stretcher for hypothermia caused by drowning in seawater, and belongs to the technical field of medical auxiliary equipment. Background Art

[0002] With the prosperity of tourism, marine sports and competitions are becoming more and more popular. At the same time, aquaculture, fishing and marine operations in coastal areas are gradually increasing. Seawater drowning incidents occur from time to time. Hypothermia often occurs when drowning in seawater. The main reasons for seawater drowning and hypothermia are as follows:

[0003] (1) Low water temperature: When the sea water temperature is low, the body will lose heat quickly, causing the body temperature to drop;

[0004] (2) Prolonged immersion: If you soak in water for too long, especially in cold seawater, your body heat will continue to be lost, increasing the risk of hypothermia;

[0005] (3) Physical exertion: During the process of struggling or swimming, the body consumes a lot of energy, which may cause the body temperature to drop;

[0006] (4) Wind and environmental factors: If the wind is strong, evaporation from the water surface will take away more heat, accelerating the loss of temperature.

[0007] Hypothermia refers to a state where the body temperature drops below the normal range, which may cause a variety of hazards. Low body temperature will affect the body's normal physiological functions and cause physiological dysfunction, including heart rate, breathing and metabolism. The specific effects on various organs are as follows:

[0008] Circulatory and heart problems: A drop in body temperature may cause heart arrhythmias, which can lead to cardiac arrest.

[0009] Effects on the nervous system: Hypothermia can lead to confusion, decreased judgment, slow reaction, and in severe cases, loss of consciousness;

[0010] Decreased muscle and motor skills: Hypothermia can lead to muscle weakness and poor coordination, increasing the risk of falls and injuries;

[0011] Immune system suppression: Prolonged hypothermia may affect the function of the immune system and increase the risk of infection;

[0012] Internal organ damage: Severe hypothermia may cause damage to internal organ function and even endanger life;

[0013] (5) Risk of death: In extreme cases, hypothermia may lead to death if not treated promptly.

[0014] In order to rescue drowning patients promptly and effectively, the first thing to do is to resuscitate the body temperature of the patients who are salvaged from the sea. This is second only to cardiopulmonary resuscitation in importance. For those hypothermic patients who are still conscious and whose heart and circulatory system are still open and whose airways are still open, they must be treated for hypothermia immediately, otherwise the treatment time will be delayed. They must be rewarmed while being transferred to a medical institution with treatment capabilities. At present, the on-site treatment for hypothermia is generally to transfer the patient to a warm environment, take off the patient's wet and cold clothing, wrap the patient with dry clothing, blankets or sleeping bags and other insulation materials, provide warm drinks, infuse warm fluids, etc., but It is important to avoid using hot water, hot water bottles or direct heat sources to directly heat the patient, so as to avoid skin burns or accelerated blood flow causing heart problems. During on-site treatment, it is necessary to monitor the patient's body temperature and pay attention to its changes. At the same time, do not let the patient do strenuous exercise to avoid accelerating the burden on the heart. If the body temperature continues to drop or does not improve, the patient must be rewarmed and vital signs must be monitored while being transferred to a medical institution with treatment capabilities for rescue. Timely treatment of hypothermia and appropriate insulation measures can significantly increase the survival chances of hypothermic patients. Currently, these methods often cannot meet the needs of rapid and effective rewarming.

[0015] Therefore, it is urgent to improve the drowning stretcher to solve the above-mentioned problems. Summary of the invention

[0034] The present invention has at least the following beneficial effects:

[0035] 1. Through the rechargeable rewarming blanket with built-in battery, at the rescue site of seawater drowning patients, the patient is made to lie flat on the stretcher, and the fixed rewarming blanket with the zipper covering half of the blanket is used to cover the patient. The other half of the open rewarming blanket is covered on the patient, and the side zipper is closed and tightened so that the patient's neck and below are completely hidden in the rewarming blanket. The head side rewarming cap is put on to provide body temperature recovery during transportation and prevent the patient's condition from worsening due to lack of timely rewarming. By designing a rechargeable rewarming blanket and a portable folding stretcher, the function of rewarming during transportation is realized to ensure the patient's life safety.

[0036] 2. A foldable water bladder strip is arranged inside the rewarming blanket, and a waterproof canvas is arranged on the outer side of the foldable water bladder strip. The waterproof canvas is made through a special process and can be moisture-proof, damp-proof and cold-proof, that is, it can protect the foldable water bladder strip and the heating glass fiber, and can facilitate the cleaning of the outer side of the rewarming blanket after use, thereby improving the convenience of use. The foldable water bladder strip is a foldable heating multiple water bladder strip, and the foldable water bladder strip contains heating glass fiber. The foldable heating multiple water bladder strip contains heating glass fiber inside, which can be quickly heated after turning on the battery or connecting to the power supply, and can increase the temperature inside the rewarming blanket in a short time, thereby improving the timeliness of rescue for rescue personnel.

[0037] 3. The water delivery valve is arranged inside the drainage hole of the rewarming blanket. When the temperature of the rewarming blanket rises, the heat conduction plate heats the heat conduction column by heat transfer. The carbon dioxide balloon expands after being heated. The expanded carbon dioxide balloon squeezes the inside of the drainage hole of the rewarming blanket to seal the drainage hole of the rewarming blanket, thereby reducing heat loss. After use, the temperature of the carbon dioxide balloon decreases, and the moisture inside the rewarming blanket flows out through the drainage hole of the heat conduction plate on the heat conduction plate after the transport stretcher body is folded. Therefore, the drainage hole of the rewarming blanket can be opened and closed by temperature changes.

[0038] 4. A brake piston cylinder is fixedly arranged inside the lower positioning block, and a self-locking piston is slidably arranged inside the brake piston cylinder. When the self-locking piston slides outward, it enters into the positioning lock hole. After the self-locking piston enters into the positioning lock hole, it forms a triangular stable structure with the lower rotating rod and the upper rotating rod on the rotating mechanism, thereby greatly improving the overall stability of the transport stretcher body.

[0039] 5. When the upper folding frame rotates relative to the lower folding frame, the extrusion block on the upper positioning block squeezes the brake airbag on the lower positioning block. After the brake airbag is squeezed, the compressed air enters the interior of the brake piston cylinder through the air duct and squeezes the self-locking piston, so that the self-locking piston enters the interior of the positioning lock hole. That is to say, in the process of unfolding the transport stretcher body, the self-locking piston will also enter the interior of the positioning lock hole to complete the instant locking, which greatly improves the efficiency of the unfolding of the transport stretcher body and shortens the rescue time.

DETAILED DESCRIPTION

[0051] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0052] like Figure 1-Figure 9 As shown, the special rewarming stretcher for seawater drowning hypothermia provided in this embodiment includes a transport stretcher body 1 and a rewarming blanket 2 fixedly arranged on the transport stretcher body 1. The stretcher can provide body temperature recovery during transportation to prevent the patient's condition from worsening due to lack of timely rewarming. The transport stretcher body 1 includes an upper folding frame 101 and a lower folding frame 102 that are rotatably connected. The upper side of the rewarming blanket 2 is connected to a zipper cover blanket 201 through a zipper. By designing a rechargeable rewarming blanket 2 and a transport stretcher body 1, the upper folding frame 101 and the lower folding frame 102 on the transport stretcher body 1 are foldable, which improves the convenience of transportation and transportation, and can also be transported while being transported. The function of rewarming at the same time ensures the life safety of the patient. The rewarming blanket 2 includes a waterproof canvas 203 and a foldable water bag strip 204 arranged inside the waterproof canvas 203. The foldable water bag strip 204 is fixedly provided with a heating glass fiber 205 inside. The heating glass fiber 205 is connected to the battery 6 through a wire. The foldable water bag strip 204 is arranged inside the rewarming blanket 2, and the waterproof canvas 203 is arranged on the outer side of the foldable water bag strip 204. The waterproof canvas 203 is made by special processing and can be moisture-proof, damp-proof and cold-proof, that is, it can protect the foldable water bag strip 204 and the heating glass fiber 205, and can also be convenient After use, the outer side of the rewarming blanket 2 is cleaned to improve the convenience of use. The foldable water bag strip 204 is a foldable heating multiple water bag strip. The foldable water bag strip 204 contains a heating glass fiber 205. The foldable heating multiple water bag strip contains a heating glass fiber inside, which can be quickly heated after turning on the battery 6 or connecting the power supply. The temperature inside the rewarming blanket 2 can be raised in a short time to improve the timeliness of rescuing rescue personnel. The battery 6 is fixedly arranged at the bottom of the upper folding frame 101. The central processor 605 is electrically connected to the battery 6. A rewarming cap 2 is connected to the rewarming blanket 2 just above the battery 6. 02, after the rescued person is placed on the transport stretcher body 1, the rewarming cap 202 is covered on the head of the rescued person to ensure that the body temperature of the rescued person recovers quickly. The rewarming cap 202 is provided with a temperature display panel 602, and a plurality of evenly distributed temperature sensors 604 are fixedly provided on the inner side of the rewarming blanket 2. The temperature sensors 604 are electrically connected to the central processor 605 through wires. A plurality of temperature sensors 604 are provided inside the rewarming blanket 2, which can detect the temperature inside the rewarming blanket 2 in real time to ensure synchronous heating and monitor the temperature in real time through the temperature display panel 602, thereby improving the convenience and timeliness of use;

[0053] After the drowning person is salvaged from the sea, a large amount of water will remain on the rescued person, and the water will accumulate inside the rewarming blanket 2. After the rescued person is sent to the hospital, it is necessary to remove the water remaining inside the rewarming blanket 2. A plurality of rewarming blanket drainage holes 206 are provided on the rewarming blanket 2 between the upper folding frame 101 and the lower folding frame 102. After the transport stretcher body 1 is used, the transport stretcher body 1 can be folded, and the water remaining on the rewarming blanket 2 will be discharged through the rewarming blanket drainage holes 206. However, if the rewarming blanket drainage holes 206 are in an open state during use, the heat in the rewarming blanket 2 will be lost. Therefore, when the transport stretcher body 1 is unfolded, the rewarming blanket drainage holes 206 need to be sealed, specifically:

[0054] A water delivery valve 4 is fixedly arranged inside the drainage hole 206 of the rewarming blanket. The water delivery valve 4 includes a heat conducting plate 401 and a carbon dioxide gas bag 404. A heat conducting column 403 is connected to the bottom side of the heat conducting plate 401. The carbon dioxide gas bag 404 is fixedly arranged on the heat conducting column 403. A plurality of heat conducting plate drainage holes 402 are opened on the heat conducting plate 401. The water delivery valve 4 is arranged inside the drainage hole 206 of the rewarming blanket. When the temperature of the rewarming blanket 2 rises, the heat conducting plate 401 heats the heat conducting column 403 by heat transfer. The carbon dioxide gas bag 404 expands after being heated, and the expanded carbon dioxide gas bag 404 squeezes the inside of the rewarming blanket drainage hole 206 to achieve the purpose of sealing the rewarming blanket drainage hole 206, thereby achieving the purpose of reducing heat loss. After use, the temperature of the carbon dioxide gas bag 404 decreases, and the moisture inside the rewarming blanket 2 flows out through the heat conduction plate drainage hole 402 on the heat conduction plate 401 after the transport stretcher body 1 is folded. Therefore, the rewarming blanket drainage hole 206 can be opened and closed by the change of temperature;

[0055] In order to facilitate the folding of the upper folding frame 101 and the lower folding frame 102, a rotating mechanism 3 is rotatably arranged between the upper folding frame 101 and the lower folding frame 102. The rotating mechanism 3 includes an upper positioning block 301 and a lower positioning block 302. The upper positioning block 301 is fixedly arranged on the upper folding frame 101, and the lower positioning block 302 is fixedly arranged on the lower folding frame 102. The upper positioning block 301 is fixedly arranged with symmetrically distributed upper rotating rods 304, and the lower positioning block 302 is arranged with a lower rotating rod 303 corresponding to the upper rotating rod 304. By fixing the upper positioning block 301 on the upper folding frame 101, The lower positioning block 302 is fixed to the lower folding frame 102, and the upper rotating rod 304 on the upper positioning block 301 corresponds to the lower rotating rod 303 on the lower positioning block 302, wherein the corresponding lower rotating rod 303 and the upper rotating rod 304 are rotatably provided with a rotating shaft 305, and then the lower rotating rod 303 and the upper rotating rod 304 are rotatably arranged together through the rotating shaft 305, so that the upper folding frame 101 and the lower folding frame 102 can rotate around the rotating shaft 305, and the rotation angle range is 0-180 degrees, which is convenient for the later folding of the transport stretcher body 1, and is convenient for transportation and carrying;

[0056] In order to improve the timeliness of rescue, a positioning lock hole 103 is opened on the upper folding frame 101, and a self-locking mechanism 5 is fixedly arranged inside the lower positioning block 302. The self-locking mechanism 5 includes a brake airbag 501 and a brake piston cylinder 503 that are connected to each other. A self-locking piston 504 is slidably arranged inside the brake piston cylinder 503. When the upper folding frame 101 and the lower folding frame 102 are in a horizontal state, the self-locking piston 504 is slidably arranged inside the positioning lock hole 103, and a brake piston cylinder 503 is fixedly arranged inside the lower positioning block 302. The self-locking piston 504 is slidably arranged inside the brake piston cylinder 503. When the self-locking piston 504 slides outward, it enters the interior of the positioning lock hole 103. After the self-locking piston 504 enters the interior of the positioning lock hole 103, it forms a triangular stable structure with the lower rotating rod 303 and the upper rotating rod 304 on the rotating mechanism 3, which greatly improves the overall stability of the transport stretcher body 1.

[0057] In order to quickly insert the self-locking piston 504 into the interior of the positioning lock hole 103, an extrusion block 506 is provided on the upper positioning block 301. The extrusion block 506 is used to squeeze the brake airbag 501. When the extrusion block 506 squeezes the brake airbag 501, the airflow inside the brake airbag 501 enters the interior of the brake piston cylinder 503 through the air guide tube 502, and then pushes the self-locking piston 504 into the interior of the positioning lock hole 103, ensuring the overall stability of the transport stretcher body 1. When the upper folding frame 101 rotates relative to the lower folding frame 102, the upper positioning block The squeezing block 506 on 301 squeezes the brake airbag 501 on the lower positioning block 302. After the brake airbag 501 is squeezed, the compressed air enters the brake piston cylinder 503 through the air guide tube 502, and squeezes the self-locking piston 504, so that the self-locking piston 504 enters the positioning lock hole 103. That is to say, in the process of unfolding the transport stretcher body 1, the self-locking piston 504 will enter the positioning lock hole 103 to complete the instant locking, which greatly improves the efficiency of unfolding the transport stretcher body 1 and shortens the rescue time.

[0058] After use, the brake airbag 501 is fixedly provided with an airbag spring 505, and the airbag spring 505 is used to squeeze the brake airbag 501. The upper side of the upper positioning block 301 is fixedly provided with a brake box 507, and the brake box 507 is fixedly provided with an extrusion block spring 508. One end of the extrusion block spring 508 is fixedly connected to the brake box 507, and the other end of the extrusion block spring 508 is fixedly connected to the extrusion block 506. The lower positioning block 302 is provided with an airbag groove 306, and the brake airbag 501 is fixedly provided inside the airbag groove 306. 501 is connected with the brake piston cylinder 503 through the air guide pipe 502. By sliding the extrusion block 506 backward, after the extrusion block 506 is separated from the brake airbag 501, the brake airbag 501 is gradually expanded under the action of the airbag spring 505. Therefore, the gas inside the brake piston cylinder 503 enters the inside of the brake airbag 501, and the self-locking piston 504 enters the inside of the brake piston cylinder 503. The upper folding frame 101 and the lower folding frame 102 are in an unlocked state, and the transport stretcher body 1 can be folded, which improves the convenience of use.

[0059] In order to improve the stability of the extrusion block 506, a brake block slide 509 is fixedly set inside the brake box 507, and a brake block slide groove 510 corresponding to the brake block slide 509 is opened on the extrusion block 506. The brake block slide groove 510 is slidably set inside the brake block slide 509, and the brake block slide 509 on the brake box 507 is slidably set inside the brake block slide groove 510 of the extrusion block 506, which facilitates the sliding of the extrusion block 506 and improves the sliding stability of the extrusion block 506.

[0060] Further, such as Figure 3and Figure 6 As shown, a plurality of support plate fixing blocks 7 are fixedly arranged on the upper folding frame 101 and the lower folding frame 102, and a stretcher support plate 701 is fixedly connected to the support plate fixing block 7 by bolts. The rewarming blanket 2 is fixedly arranged on the upper side of the rewarming blanket 2. The stretcher support plate 701 is fixedly arranged on the upper folding frame 101 and the lower folding frame 102 by a plurality of support plate fixing blocks 7, which can improve the overall stability of the transport stretcher body 1 to prevent the drowning person from suffering secondary injuries, and can also fix the rewarming blanket 2 to improve the stability of the rewarming blanket 2, wherein the rewarming blanket 2 is fixedly arranged on the upper folding frame 101. A vent hole 207 is provided on the front end stretcher support plate 701, and the vent hole 207 is connected with the interior of the rewarming blanket 2. An air inlet box 9 corresponding to the vent hole 207 is provided on the bottom side of the stretcher support plate 701, and the air inlet box 9 is connected with the vent hole 207. A fan 901 is fixedly provided inside the air inlet box 9, and the fan 901 is electrically connected to the central processing unit 605 through a wire. After the temperature inside the rewarming blanket 2 rises, air flow is introduced into the interior of the rewarming blanket 2 through the fan 901, and the temperature distribution inside the rewarming blanket 2 is made more uniform by the flow of gas.

[0061] Furthermore, if Figure 2 and Figure 6 As shown, a charging connector 601 and a power switch 603 are fixedly provided on the battery 6, and both the charging connector 601 and the power switch 603 are electrically connected to the central processor 605 through a wire. The charging connector 601 and the power switch 603 are connected to the battery 6, which is convenient for charging the battery 6. At the same time, the power supply is energized through the power switch 603, which improves the convenience of use;

[0062] The upper folding frame 101 and the lower folding frame 102 are both fixedly provided with a stretcher guardrail 8, which can protect the transport stretcher body 1 and improve the safety of drowning personnel.

At the same time, the storage battery 6 is fixed to the bottom of the transport stretcher body 1 through the battery fixing plate 10, which can also improve the stability of the storage battery 6 and the central processing unit 605.

[0063] like Figure 1 As shown, an inflatable headrest 12 is fixedly provided at the bottom of the rewarming cap 202, and the inflatable headrest 12 is connected to the vent hole 207. An inflatable headrest 12 is fixedly provided inside the rewarming blanket 2. When in use, gas can be filled into the inflatable headrest 12 through the vent hole 207 to improve the comfort of the drowning person.

[0065] The rewarming blanket 2 includes a waterproof canvas 203 and a foldable water bag strip 204 arranged inside the waterproof canvas 203. A heating glass fiber 205 is fixedly arranged inside the foldable water bag strip 204. The heating glass fiber 205 is connected to a battery 6 through a wire. The foldable water bag strip 204 is arranged inside the rewarming blanket 2. The outer side of the foldable water bag strip 204 is provided with a waterproof canvas 203. The waterproof canvas 203 is made by a special process and can be moisture-proof, damp-proof and cold-proof, that is, it can protect the foldable water bag strip 20 4 and the heatable glass yarn 205 are used for protection, and the outer side of the rewarming blanket 2 can be easily cleaned after use, thereby improving the convenience of use. The foldable water bag strip 204 is a foldable heating multiple water bag strip, and the foldable water bag strip 204 contains the heatable glass yarn 205. The foldable heating multiple water bag strip contains the heatable glass yarn inside, which can be quickly heated after the battery 6 is turned on or the power is turned on, and the temperature inside the rewarming blanket 2 can be increased in a short time, thereby improving the timeliness of rescuing the rescue personnel;

[0066] The water delivery valve 4 is arranged inside the drainage hole 206 of the rewarming blanket. When the temperature of the rewarming blanket 2 increases, the heat conducting plate 401 heats the heat conducting column 403 by heat transfer, and the carbon dioxide balloon 404 expands after being heated. The expanded carbon dioxide balloon 404 squeezes the inside of the drainage hole 206 of the rewarming blanket to achieve the purpose of sealing the drainage hole 206 of the rewarming blanket, thereby achieving the purpose of reducing heat loss. After use, the temperature of the carbon dioxide balloon 404 decreases, and the moisture inside the rewarming blanket 2 flows out through the heat conducting plate drainage hole 402 on the heat conducting plate 401 after the transport stretcher body 1 is folded. Therefore, the opening and closing of the drainage hole 206 of the rewarming blanket can be achieved by temperature changes.
