[0002] Transfer bed is essential medical equipment of hospital, it can realize transfer between patient from sickbed, operating table or ambulance, such as solve the difficulty of patient from operating room or operating table removal to ward for rehabilitation.And in winter and summer, patient needs to be kept warm after operation, since the physique of patient is generally poor, especially after intraspinal anesthesia operation, too big temperature change often brings adverse effect to patient, patient is difficult to tolerate higher or lower temperature, easily body temperature drops and causes resistance to drop, easily causes related disease to occur.Therefore, it needs to be kept warm to patient in the course of transportation by constant temperature transfer bed, to ensure that the body of patient recovers quickly.

[0003] In prior art, medical staff will use hair dryer to heat the inside of the bedding of transfer bed, which needs to pay double attention to the normal ventilation of heating equipment to avoid fire.In addition, since bedding has the effect of hindering the rapid transmission of heat, when the time of blowing inside the bedding with hair dryer is insufficient, there may still be the phenomenon of uneven heating or higher temperature on the surface layer of bedding and insufficient temperature on the inner layer, and the surface layer cooling phenomenon is obvious after lying down, and patients are easy to have the phenomenon of hot and cold when using.

[0004] Sometimes heating mattress is used to contact the bedding on it with heat, since bedding has the effect of hindering the rapid transmission of heat, it takes a long time to heat the inside and outside relatively thoroughly, and it takes nearly 20 minutes to heat it to comfortable temperature sometimes, which leads to the time of patient staying in operating room too long, not only affects the operating time, but also increases the time cost of operation anesthesia operation.Finally, it is easy for weaker patients to lie on the transfer bed with incomplete heating and return to ward, or slightly weaker patients to walk back to ward with family accompaniment.

[0005] Investigation shows that the common complication of intraspinal anesthesia is chills reaction, the incidence is 5%-65%, which is the body temperature regulation reaction made by the body to cold stimulation, the uncontrollable muscle tremor brings discomfort to the patient, and even has a serious impact on the operation, the monitoring during the operation is disturbed, the oxygen consumption and metabolic rate of the body are increased obviously, the heart and lung function are low, which leads to the aggravation of the disease, thereby inducing the incidence of instability of hemodynamics during the operation anesthesia, the patient lies on a large range of unheated transfer bed, the short-term vascular constriction affects the change of hemodynamics, and the long-term influence is to reduce the wound healing speed. Therefore, scholars such as Wang Maolin believe that the influencing factors of feeling cold, feeling uncomfortable or causing chills need to be analyzed, and targeted treatment and intervention methods are beneficial to obtain good cure effect. It is recorded in the“Influencing Factors and Clinical Treatment Analysis of Chills after Intraspinal Anesthesia (Wang Maolin, Guo Jinli, Shi Xiuhong)”。

DETAILED DESCRIPTION

[0047] In order to make the personnel in the technical field better understand the utility model scheme, the technical scheme in the utility model embodiments will be clearly and completely described below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0048] The utility model rapid heating type postoperative transfer device will be further described below in combination with the drawings and specific embodiments: as Figure 1As shown, the application contains a mobile bed frame 2, a cloth heating device 5, a soft pad 4, a warm quilt, an air heating device 8, an air pipe 7 and an air pushing device 9. The cloth heating device 5 and the soft pad 4 are sequentially laid on the mobile bed frame 2. The air outlet 8-4 of the air pushing device 9 is connected to the air heating device 8 and the cloth heating device 5 through the air pipe 7. The air escapes from the upper surface of the cloth heating device 5 and sequentially flows through the soft pad 4 and the warm quilt.

[0049] As shown in the first embodiment, Figures 2-4 The cloth heating device 5 contains an upper plate 5-1, an upper side plate 5-6, a lower plate 5-4, a lower side plate 5-5 and support columns 5-3. The upper plate 5-1 is uniformly provided with a plurality of air holes 5-2. The upper plate 5-1 and the lower plate 5-4 are respectively provided with the upper side plate 5-6 and the lower side plate 5-5 around the periphery. The upper side plate 5-6 and the lower side plate 5-5 are connected to each other. A plurality of support columns 5-3 are correspondingly arranged between the opposite inner sides of the upper plate 5-1 and the lower plate 5-4.

[0050] The support columns 5-3 are connected by the positioning columns 5-3-1 and the positioning concave holes 5-3-2. The upper side plate 5-6 and the lower side plate 5-5 are connected by the positioning columns 5-3-1 and the positioning concave holes 5-3-2 or by the positioning convex strips 5-7-1 and the positioning concave grooves 5-7-2.

[0051] The air pipe 7 contains an air main pipe 7-1 and air branch pipes 7-2, i.e. a main pipe and branch pipes structure, which can more evenly distribute the hot air in the cloth heating device 5 and then flow out. The upper plate 5-1 is connected to the lower plate 5-4 through the support columns 5-3, which can form a hollow cloth heating device 5. The upper side plate 5-6 and the lower side plate 5-5 can be sealed around the periphery by being butted, which can ensure that the inside of the cloth heating device 5 is a closed cavity and the hot air inside can flow smoothly and escape from the air holes 5-2 of the upper plate 5-1.

[0052] In order to prevent the support columns 5-3 between the upper and lower surfaces from being dislocated after long-term lying, the positioning columns 5-3-1 and the positioning concave holes 5-3-2 can be arranged at the contact surfaces of the two support columns 5-3. The cloth heating device 5 is not easy to be damaged by pressure deformation after long-term use.

[0053] As shown in the second embodiment, Figures 5-8 The cloth heating device 5 contains an upper plate 5-1, an upper side plate 5-6, a lower plate 5-4, a lower side plate 5-5 and support columns 5-3. The upper plate 5-1 is uniformly provided with a plurality of air holes 5-2. The upper plate 5-1 and the lower plate 5-4 are respectively provided with the upper side plate 5-6 and the lower side plate 5-5 around the periphery. The upper side plate 5-6 and the lower side plate 5-5 are connected to each other. A plurality of support columns 5-3 are correspondingly arranged between the opposite inner sides of the upper plate 5-1 and the lower plate 5-4.

[0054] The support strips 5-7 are paired and connected by mutually cooperating positioning protrusions 5-7-1 and positioning grooves 5-7-2; the upper side plate 5-6 and lower side plate 5-5 are paired and fitted together. The air supply pipe 7 also contains a main air supply pipe 7-1 and branch air supply pipes 7-2, i.e., a main pipe with multiple branches, which can more evenly distribute hot air within the heat distribution device 5 before it flows out. The upper plate 5-1 is also connected to the lower plate 5-4 through the support strips 5-7, thus forming a hollow heat distribution device 5. The upper side plate 5-6 and lower side plate 5-5 are respectively installed around the upper plate 5-1 and lower plate 5-4 to seal the four sides, ensuring that the interior of the heat distribution device 5 is a closed cavity, allowing the hot air inside to flow smoothly and escape from the vent holes 5-2 of the upper plate 5-1.

[0055] To prevent the support bars 5-7 between the upper and lower surfaces from shifting after prolonged use, positioning protrusions 5-7-1 and positioning grooves 5-7-2 can be provided at the contact surfaces of the two support bars 5-7. This will prevent the heating device 5 from being damaged by pressure deformation after long-term use. The support bars 5-7 can be arranged horizontally or vertically at intervals. The number of vent holes 5-2 penetrating the upper plate 5-1 increases with the distance between them and the nearest air outlet 8-4 of the air supply pipe 7. That is, the farther the location, the more air outlets 8-4 are needed, and the larger the cross-sectional area of ​​the air outlet is. This ensures that the flow rate of hot air at the air outlets 8-4 is relatively uniform.

[0056] Example 3, as Figure 9 , 10 As shown, the heat distribution device 5 includes an upper plate 5-1, an upper side plate 5-6, a lower plate 5-4, a lower side plate 5-5, and a closed support ring 5-8. The upper plate 5-1 has multiple vent holes 5-2 evenly distributed on it. The upper plate 5-1 and the lower plate 5-4 are respectively provided with upper side plates 5-6 and lower side plates 5-5 around their perimeters. The upper side plates 5-6 and lower side plates 5-5 are connected to each other. A support ring 5-8 is provided between the inner surfaces of the upper plate 5-1 and the lower plate 5-4. The gas supply pipe 7 is divided into a primary gas supply pipe 7-3 and a secondary gas supply pipe 7-4.

[0057] One end of the primary air supply pipe 7-3 is connected to the air outlet 8-4 of the air heating device 8 via a primary valve 7-3-3, and the other end is connected to the primary cavity enclosed by the upper plate 5-1, the lower plate 5-4, and the inner ring surface of the support ring 5-8. One end of the secondary air supply pipe 7-4 is connected to the air outlet 8-4 of the air heating device 8 via a secondary valve 7-4-3, and the other end is connected to the secondary cavity enclosed by the outer ring surface of the support ring 5-8, the upper plate 5-1, the upper side plate 5-6, the lower plate 5-4, and the lower side plate 5-5.

[0058] The support ring 5-8 is connected by the positioning convex strip 5-7-1 and the positioning concave groove 5-7-2. The upper side plate 5-6 and the lower side plate 5-5 are opposite to each other, and the inner side of the upper side plate 5-6 is sleeved on the outer side of the lower side plate 5-5. The upper plate 5-1 and the lower plate 5-4 are buckled to each other. The support ring 5-8 is in the shape of a square, an ellipsoid or close to the shape of the outer contour of a human body. The upper plate 5-1 is connected to the lower plate 5-4 through the support ring 5-8, so as to form a hollow upper and lower surface of the heat distribution device 5. The upper side plate 5-6 and the lower side plate 5-5 are arranged on the periphery of the upper plate 5-1 and the lower plate 5-4 respectively, so as to ensure that the heat distribution device 5 is divided into two cavities. A first cavity is formed between the inner side of the support ring 5-8, the upper plate 5-1 and the lower plate 5-4. A second cavity is formed between the outer side of the support ring 5-8, the upper plate 5-1, the lower plate 5-4, the upper side plate 5-6 and the lower side plate 5-5. The two cavities are respectively supplied with air, and the hot air can flow smoothly and escape from the air holes 5-2 on the upper plate 5-1.

[0059] Meanwhile, a plurality of support columns 5-3 can be arranged between the upper plate 5-1 and the lower plate 5-4 of the first cavity and the second cavity, so as to prevent the support ring 5-8 from being pressed and deformed during lying. Alternatively, in order to prevent the support ring 5-8 from being misaligned between the upper surface and the lower surface, the positioning convex strip 5-7-1 and the positioning concave groove 5-7-2 can be arranged at the contact surface of the two opposite support rings 5-8. Thus, the heat distribution device 5 is not prone to deformation and damage after long-term use.

[0060] The support ring 5-8 is connected by the positioning convex strip 5-7-1 and the positioning concave groove 5-7-2. The upper side plate 5-6 and the lower side plate 5-5 are opposite to each other, and the inner side of the upper side plate 5-6 is sleeved on the outer side of the lower side plate 5-5. The upper plate 5-1 and the lower plate 5-4 are buckled to each other. The support ring 5-8 is in the shape of a square, an ellipsoid or close to the shape of the outer contour of a human body. The upper plate 5-1 is connected to the lower plate 5-4 through the support ring 5-8, so as to form a hollow upper and lower surface of the heat distribution device 5. The upper side plate 5-6 and the lower side plate 5-5 are arranged on the periphery of the upper plate 5-1 and the lower plate 5-4 respectively, so as to ensure that the heat distribution device 5 is divided into two cavities. A first cavity is formed between the inner side of the support ring 5-8, the upper plate 5-1 and the lower plate 5-4. A second cavity is formed between the outer side of the support ring 5-8, the upper plate 5-1, the lower plate 5-4, the upper side plate 5-6 and the lower side plate 5-5. The two cavities are respectively supplied with air, and the hot air can flow smoothly and escape from the air holes 5-2 on the upper plate 5-1.

[0061] The air supply pipe 7 in the embodiment comprises a first air supply pipe 7-3 and a second air supply pipe 7-4. The first air supply pipe 7-3 comprises a first air supply main pipe 7-3-1 and a first air supply branch pipe 7-3-2. The first air supply pipe 7-3 supplies hot air to the first cavity. The first air supply pipe 7-3 can heat the cushion 4 in the lying position of the human body in a short time, so as to meet the needs of patients who need to lie down in a short time, and avoid the patients waiting for a long time or waiting for a time equal to the time of walking back to the ward by themselves.

[0062] The secondary air supply pipe 7-4 includes a secondary air supply main pipe 7-4-1 and a secondary air supply branch pipe 7-4-2, which supply hot air to the secondary cavities. After the primary air supply pipe 7-3 supplies hot air to the primary cavities, the secondary air supply pipe 7-4 can supply hot air to the secondary cavities outside the lying part of the patient, so that the patient can freely change the body posture without feeling the cold and hot alternation of the lying part.

[0063] The primary air supply pipe 7-3 and the secondary air supply pipe 7-4 both adopt the pipe structure of one main pipe and multiple branch pipes, so that the hot air can be more evenly distributed between the primary cavities and the secondary cavities of the heat distribution device 5 and then flow out.

[0064] The thickness, material and heat resistance of the air supply pipe 7 in the heat distribution device 5 in the first embodiment to the third embodiment can be selected according to the actual situation. The positions of the connection points between the air supply pipe 7 and the upper plate 5-1, the upper side plate 5-6, the lower plate 5-4 and the lower side plate 5-5 can also be selected according to the actual situation. The number of the air holes 5-2 increases with the distance from the air hole 5-2 to the air outlet 8-4 of the nearest air supply pipe 7. As shown in Figure 14 , the openings of the air holes 5-2 on the upper plate 5-1 can be inconsistent.

[0065] As shown in Figure 12 , the soft pad 4 is a sponge pad or a cotton pad. It is a loose and porous sponge pad or a cotton pad with good air permeability, which needs to be specially ordered. If the ordinary bedding is directly replaced, the air permeability will be slightly poor and the temperature rising speed will be slightly slow. As shown in Figure 13 , the heat preservation pad 6 is laid between the moving bed frame 2 and the heat distribution device 5, which can greatly reduce the heat loss between the lower plate 5-4 of the heat distribution device 5 and the moving bed frame 2 and between the lower plate 5-4 and the air, and can be beneficial to the rapid temperature rising of the inside of the soft pad 4 above.

[0066] The upper surface of the heat distribution device 5 and the lower surface of the soft pad 4 are fixed by the connecting piece, such as the magic sticky 4-1 or the snap connection on the upper plate 5-1 on the upper surface of the heat device. Even if a large amount of air is supplied through the air holes 5-2 and then blown to the soft pad 4, the soft pad 4 will not be blown off, and the hot air near the periphery of the soft pad 4 can be prevented from easily drifting to the periphery of the soft pad 4, causing the periphery of the soft pad 4 to be slightly cool, so that the hot air can pass through the inside and outside of the soft pad 4.

[0067] As shown in Figure 15As shown, the air heating device 8 contains a closed shell 8-1 and a heating component 8-2, the two ends of the closed shell are respectively provided with an air inlet 8-3 and an air outlet 8-4, and the inside is provided with the heating component 8-2, which is a heating rod or a heating wire. The heating rod or the heating wire inside the shell 8-1 generates enough heat during power-on, which is taken away by the air flowing through the air inlet 8-3 and the air outlet 8-4 of the closed shell 8-1 and the air outlet 8-4 of the closed shell 8-1, and is dispersed and flows out in the heat distribution device 5, penetrates into the inside of the soft cushion 4, uniformly heats and warms it up, and increases the heat exchange area between the inside and the outside of the soft cushion 4, so as to achieve uniform heating and avoid the heat-insensitive phenomenon of the soft cushion 4 caused by the conventional heating mode. The heat-insensitive phenomenon is that the patient feels warm at first, and then feels cold after a while. In the preheating stage, the water-proof mattress 3 can be placed first, which is more conducive to the warming of the soft cushion 4. The soft cushion 4 is warmed to about 40 degrees through heat transfer, which is higher than the hospital room temperature of about 25 degrees. The medical staff can determine the final warming degree by touching and feeling.

[0068] As shown in Figure 11 The lower half of the water-proof mattress 3 is a water-proof layer 3-1, and the upper half is a flexible pad formed by a water-absorbing layer 3-2. It not only can enhance the ventilation of the lower half of the patient, but also can avoid the patient from dirtying the lower soft cushion 4 and increase unnecessary cleaning workload. Whether the cotton pad is laid with a water-proof pad or replaced by a disposable treatment towel can be determined by medical staff, and finally meets the requirements of hospital infection.

[0069] Since the medical staff needs 3-5 minutes to prepare for patient transfer, the power of the air heating device 8 and the air volume provided by the air pushing device 9 can be adjusted to meet the heating speed requirement. After the temperature is enough, the water-proof mattress 3, the disposable contact isolation pad and the thermal quilt are placed. After the patient lies down, the soft cushion 4 can be continuously heated and warmed by the heat distribution device 5 according to the patient's requirements through the secondary valve 7-4-3 and / or the primary valve 7-3-3, or the heating operation is turned off according to the patient's will.

[0070] The pillow 1 can be an electric heating pillow, an inflatable pillow or a hot water-filled pillow. The electric heating pillow heats the heating wire inside the pillow by low-voltage direct current. The inflatable pillow can be filled with a certain amount of gas. The hot water-filled pillow can be filled with a certain amount of hot water. The height can be adjusted according to the patient's needs. The internal temperature and whether the pillow 1 is used can also be determined according to the patient's condition.

[0071] The mobile bed frame 2 can facilitate the nursing staff to transfer the patient between different places. In the preheating process before heating, the air heating device 8 on it can be powered by 220V alternating current, at this time the preheating heat power can use the highest grade, and the air flow rate can also be adjusted in size by the air pushing device 9, such as selecting a large-power positive pressure fan with adjustable speed or opening an air compressor with a certain amount of gas stored inside to realize rapid air supply, so that enough hot air passes through the soft cushion 4 to rapidly preheat and warm it up. If cost reduction is required during use, the air compressor can not be installed on the transfer bed, but placed in the transfer bed placement area, and multiple transfer beds can share one air compressor. The air compressor can be preferably a silent type, or a centralized air supply through a compressed gas supply pipe. A large-power positive pressure fan can also be installed on the transfer bed, and the air compressor can use detachable pipelines to serve multiple transfer beds to realize rapid air supply. When the patient needs to be transferred after preheating, the detachable pipeline of the air compressor is pulled out and the pipe opening is closed, and only the large-power positive pressure fan on each transfer bed is used for air supply. Because the person lies on it, the heating capacity and air flow rate in the cloth heating device 5 can be a little smaller. It is not recommended to use the air compressor and the large-power positive pressure fan at the same time, because the air supply speed and capacity of the two are different.

[0072] When the patient needs to lie on it, the medical staff can pull out the alternating current plug and switch to the battery on it to power the air heating device 8, and the heat power required during heat preservation is lower than that during rapid preheating. The battery can use a 12-72V lead-acid battery or a lithium battery, and an inverter is connected around the battery to provide 220V alternating current. The air heating device 8 can use direct current for heating during the transfer process, and the air pushing device 9 can use alternating current after inversion for air flow.

[0073] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
