Description

Technical Field

[0001] The invention relates to the technical field of temperature increasing devices, in particular to a medical temperature increasing device. Background Art

[0002] Medical warming devices (medical warming blankets) are used to warm patients during surgery, which is beneficial for maintaining a stable body temperature, avoiding the occurrence of hypothermia during surgery, and ensuring the regulation of normal physiological functions of the body. Medical warming devices can reduce surgical risks. And can prevent a series of complications caused by hypothermia. Common medical warming devices are composed of a host, an air supply pipe, and a body surface warming blanket. The air supply pipe is used to fill the body surface warming blanket covering the patient. After the hot air transfers the heat to the human body, it is discharged from the air outlet. This continuous cycle allows the patient to maintain a normal body temperature.

[0003] In the related technology, a search revealed a scheme of a portable medical inflatable warming device (Announcement No. CN214018078U), which covers the upper part of the patient's body with an air cushion and wraps the sides and connects to a power source. The electric heating wire heats the surrounding air, and under the action of the blower fan, hot air is blown into the air cushion. When the hot air passes through the air cushion, it radiates heat downward, thereby keeping the patient's body temperature within a normal range and preventing the patient from experiencing abnormal conditions due to hypothermia.

[0004] However, the heating device of the above scheme is provided with an air outlet, and the air outlet is connected to the inflatable insulation device through a hollow bellows. Since the bellows of the medical thermometer is made of soft plastic, its strength is limited. When the bellows is connected to the air cushion, there will be a gap at the connection, which is prone to air leakage. In addition, the gap also affects the stability of the connection between the bellows and the air cushion. When the air volume of the medical thermometer is increased, the bellows will be separated from the air cushion because it is not inserted tightly. At this time, medical staff are required to reconnect the bellows and the air cushion, affecting the progress of the operation. The medical thermometer is also used after the operation to maintain the patient's body temperature. If the bellows is accidentally separated from the air cushion, it will affect the patient's recovery, and optimization and improvement are still needed. Summary of the invention

[0005] The object of the present invention is to provide a medical warming device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medical warming device, comprising a housing, the housing is produced by injection molding, the injection molding process can realize automated production, improve production efficiency, shorten the production cycle, and facilitate manufacturers to manufacture;

[0007] A cylinder shell and a heat-insulating shell are installed inside the casing, a fan is installed inside the cylinder shell, a heating rod is installed inside the heat-insulating shell, and the cylinder shell and the heat-insulating shell are connected, a connector is provided on the upper surface of the casing, and the connector is connected to the heat-insulating shell, and a hose is installed inside the connector;

[0008] The fan uses a brushless motor. When the brushless motor is running, it uses the interaction between current and magnetic field to achieve rotation. There is no friction part inside, so the fan rotates more smoothly, consumes less power, has a longer service life, and can reduce the noise of the fan. If used during surgery, the noise interference is not obvious.

[0009] A main control board, the main control board is installed inside the housing, a microcontroller, a three-speed air volume control switch, a three-speed temperature control switch, a temperature probe, a display screen, a Bluetooth infrared temperature measuring earplug, and a USB port are electrically connected to the main control board, the fan and the heating rod are electrically connected to the main control board, and the temperature probe is inserted into the connector;

[0010] The air volume and temperature gears can be checked on the display screen, and the working status of the fan and the heating rod can be checked more intuitively. The air temperature discharged from the connector is measured by a temperature probe and displayed in real time on the display screen to achieve temperature monitoring;

[0011] An anti-drop-off tube, the anti-drop-off tube is fixedly connected to the surface of the hose, a plurality of rope rings are arranged on the surface of the anti-drop-off tube, a sealing belt is inserted in the rope ring, a limiting block is fixedly connected to the surface of the anti-drop-off tube, a turntable is rotatably connected inside the limiting block, a plurality of limiting grooves are arranged on the surface of the turntable, a pressing sheet is installed on the surface of the limiting block, and the pressing sheet is against the surface of the turntable, a limiting head is arranged on the lower surface of the pressing sheet, and the size of the limiting head corresponds to the limiting groove;

[0012] The sealing belt is woven from woven wire to ensure that the seal will not break. Turning the dial can tighten the sealing belt, which tightens the anti-slip tube, making the anti-slip tube fit tightly with the air inlet head, which can prevent the hose from separating from the air inlet head, thereby preventing the hose from being disconnected from the warming blanket, ensuring that the warming blanket provides a more stable thermal insulation environment for the patient, avoiding the occurrence of shallow body temperature syndrome during surgery, and medical staff do not need to worry about the problem of the hose being disconnected from the warming blanket;

[0013] Furthermore, a leg is provided on the lower surface of the casing, an anti-skid pad is provided on the lower surface of the leg, a placement plate is installed at the lower end of the leg, an arm is provided on the lower surface of the placement plate, a movable seat is installed at the lower end of the arm, and a storage box is installed on the surface of the arm. The design of the legs and the anti-skid pad can increase the stability of the casing and prevent the casing from sliding. The design of the placement plate makes it convenient to move the casing, and the design of the movable seat further enhances this convenience. The storage box installed on the arm can be used not only to place items, but also to place hoses.

[0014] Furthermore, the surface of the placement board is provided with an anti-skid groove, and a magnetic sheet is provided inside the anti-skid groove. The legs are placed inside the anti-skid groove, and the magnetic sheet is used to adsorb the legs. The combined use of the anti-skid groove and the magnetic sheet can more firmly fix the legs and enhance the stability of the placement of the casing. The use of the magnetic sheet makes the installation and disassembly of the legs convenient, simplifies the operation process, and facilitates the removal of the casing from the placement board. The design of the anti-skid groove can increase the friction force on the surface of the placement board to prevent the casing from sliding during placement or movement. The way the magnetic sheet adsorbs the legs has high reliability and is not prone to loosening or falling off, thereby ensuring the stability of the casing placement and preventing the casing from falling off the placement board when accidentally touched.

[0015] Furthermore, an air inlet head is sleeved on the surface of the hose, and the air inlet head is located between the anti-detachment tube and the hose, and the other end of the air inlet head is connected to a warming blanket, and a pressure relief nozzle is provided on the warming blanket. After the air in the warming blanket is discharged through the pressure relief nozzle, the air circulation inside the warming blanket can be ensured, ensuring that the hot air delivered by the fan and the heating rod can be continuously delivered to the warming blanket, ensuring that the temperature of the warming blanket will not drop, and maintaining the patient's body temperature.

[0016] Furthermore, a handle is provided on the upper surface of the casing, and the right end of the handle is fixedly connected to the connecting head to improve the connection strength of the handle and ensure that the handle will not break. The legs of the casing are attracted by the magnetic sheet, so when the casing is lifted by the handle, the casing can be directly removed from the placement plate, which is convenient for moving the casing.

[0017] Furthermore, a perforated plate is provided inside the connecting head, and a one-way blade is rotatably connected to the surface of the orifice plate, and the one-way blade covers the surface of the orifice plate. The setting of the one-way blade can effectively block external dust from entering the interior of the casing, prevent dust from damaging the internal components of the casing or affecting its normal operation, and extend the service life of the heating equipment.

[0018] Furthermore, a card tube is provided on the inner wall of the casing, a baffle is plugged into the card tube, two plug-in frames are provided on the side of the baffle, a filter is plugged into the plug-in frame, and the filter is blocked at the left end of the cylinder casing. The filter is installed by plugging, which is convenient for disassembly and cleaning of the filter. Two filters are provided for replacement, and when one of the filters is cleaned, the other can be used as a standby.

[0019] A handle is provided on the side of the filter screen, and a strip hole is provided on the surface of the handle. The filter screen can be removed by fingers through the strip hole of the handle. The baffle can be rotated with the clamping tube as a fulcrum, and then the two filters can be replaced, and dust will not be sucked out by the fan.

[0020] Furthermore, the surface of the turntable is provided with a knob integrally formed with the turntable, which can improve the stability of the connection between the knob and the turntable. Using the knob to rotate the turntable can more easily control the rotation of the turntable, thereby tightening the sealing belt and better improving the stability of the connection between the air intake head and the hose.

[0021] Furthermore, a partition is provided inside the insulation shell, and a U-shaped air duct is formed between the partition and the insulation shell, which can extend the time that the air stays inside the insulation shell, so that the air is fully heated by the heating rod, ensuring that the air temperature meets the standard, and then the air delivered to the warming blanket is the same as the set temperature, providing a more stable insulation effect for the patient.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The connection between the hose and the warming blanket is achieved by plugging the air inlet head and the hose. When the knob is turned, the turntable is driven to rotate. When the turntable tightens the sealing belt, the anti-drop tube is tightened, so that the anti-drop tube and the hose cooperate to clamp the air inlet head, thereby improving the stability of the connection between the hose and the warming blanket. The gap at the connection can be reduced, and air leakage is less likely to occur. When the air volume of the warming equipment is increased, the hose and the air inlet head are plugged tightly, which will not affect the operation. After the operation, the warming equipment is used to maintain the patient's body temperature, and the hose and the warming blanket will not separate, which is beneficial to the patient's recovery.

[0024] (2) The air volume of the fan can be controlled by the three-speed air volume control switch, and the three-speed temperature control switch can control the temperature level of the heating rod. The temperature of the air after heating can be detected by the temperature probe. The set temperature and air temperature can be checked on the display screen to determine whether the heated air is too high or too low. Real-time temperature adjustment can be performed to facilitate control of the heating temperature.

[0025] (3) The two filters can be switched by rotating the baffle. After the air drawn by the fan is filtered by the filter, dust can be prevented from entering the cylinder shell. When air is transported to the heating blanket, dust can also be prevented from entering the heating blanket.

[0026] (4) The filter can be removed from the plug-in frame by the handle, which is convenient for cleaning the filter. When there is dust accumulation in the plug-in frame, the baffle can be pulled out from the card tube to clean the plug-in frame and reduce dust accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example:

[0037] See also Figure 1-7 The present invention provides a technical solution: a medical temperature-increasing device, comprising a housing 7, a cylindrical shell 20 and a heat-insulating shell 22 are installed inside the housing 7, a fan 21 is installed inside the cylindrical shell 20, a heating rod 23 is installed inside the heat-insulating shell 22, and the cylindrical shell 20 and the heat-insulating shell 22 are connected, a connector 9 is provided on the upper surface of the housing 7, and the connector 9 is connected to the heat-insulating shell 22, and a hose 10 is installed inside the connector 9;

[0038] The housing 7 is made of ABS plastic, which has excellent impact resistance, wear resistance and dimensional stability. ABS plastic has high heat resistance and is not easily affected by temperature. ABS plastic has excellent electrical properties, thereby increasing the service life of the housing 7.

[0039] A main control board 14, the main control board 14 is installed inside the housing 7, and the main control board 14 is electrically connected with a microcontroller 39, a three-speed air volume control switch 11, a three-speed temperature control switch 12, a temperature probe 24, a display screen 13, a Bluetooth infrared temperature measuring earplug 42, and a USB socket 43. The Bluetooth infrared temperature measuring earplug 42 is worn by the patient, and the patient's body temperature is detected by infrared sensing in the Bluetooth infrared temperature measuring earplug 42, and transmitted to the main control board 14 by Bluetooth, so that the heating device automatically adjusts the temperature of the output air according to the real-time detected patient temperature. The USB socket can be connected to a charging bin adapted to the Bluetooth infrared temperature measuring earplug 42, so that the Bluetooth infrared temperature measuring earplug 42 can be charged conveniently using the charging bin, and the USB socket 43 can also power some devices using USB cables;

[0040] The fan 21 and the heating rod 23 are electrically connected to the main control board 14, and the temperature probe 24 is inserted into the connector 9. The main control board 14 has a power module that can adjust the voltage and current to provide corresponding power for the fan 21 and the heating rod 23. The three-speed temperature control switch 12 controls the maximum temperature of the heating rod 23 to not exceed 42 degrees Celsius to avoid scalding. The affected side can be kept warm and the patient is not scalded.

[0041] An anti-dropping tube 29, the anti-dropping tube 29 is fixedly connected to the surface of the hose 10, a plurality of rope rings 34 are provided on the surface of the anti-dropping tube 29, a sealing belt 35 is inserted in the rope ring 34, a limiting block 30 is fixedly connected to the surface of the anti-dropping tube 29, a rotating disk 31 is rotatably connected inside the limiting block 30, a plurality of limiting grooves 38 are provided on the surface of the rotating disk 31, a pressing sheet 33 is installed on the surface of the limiting block 30, and the pressing sheet 33 is against the surface of the rotating disk 31, a limiting head 36 is provided on the lower surface of the pressing sheet 33, and the size of the limiting head 36 corresponds to the limiting groove 38;

[0042] like Figure 5As shown, the surface of the anti-detachment tube 29 has several grooves, so that the anti-detachment tube 29 can have better elasticity and can be better contracted, and then fit with the air inlet head 37 to prevent the air inlet head 37 from being separated from the hose 10. The clamping plate 33 has a V-shaped portion, which can improve the elasticity of the clamping plate 33, so that the limit head 36 can be more stably inserted into the limit groove 38. The clamping plate 33 can also be moved by the V-shaped portion of the clamping plate 33 to separate the limit head 36 from the limit groove 38, ensuring that the clamping plate 33 does not affect the rotation of the turntable 31. When separating the air inlet head 37 and the hose 10, the anti-detachment tube 29 is prevented from getting stuck on the air inlet head 37, and the air inlet head 37 can be removed from the hose 10.

[0043] In this embodiment, if Figure 1 As shown, the lower surface of the housing 7 is provided with a leg 25, the leg 25 is made of iron and can be attracted by a magnet sheet 26, and the lower surface of the leg 25 is provided with an anti-skid pad 27 to improve the anti-skid ability of the housing 7 after being placed, and a placement plate 6 is installed at the lower end of the leg 25, and an arm 2 is provided on the lower surface of the placement plate 6, and a moving seat 1 is installed at the lower end of the arm 2, and a storage box 3 is installed on the surface of the arm 2;

[0044] The movable seat 1 has a universal locking wheel to facilitate the movement of the casing 7. The support arm 2 is provided with a certain length, and the casing 7 is made at a suitable height to facilitate medical staff to operate the warming equipment. The storage box 3 can hold the hose 10 to prevent the hose 10 from contacting the ground, and can also temporarily place the warming blanket 4. The casing 7 and the warming blanket 4 can be moved simultaneously through the movable seat 1.

[0045] In this embodiment, if Figure 2 As shown, the surface of the placement plate 6 is provided with an anti-skid groove, and a magnetic sheet 26 is arranged inside the anti-skid groove. The leg 25 is placed inside the anti-skid groove, and the magnetic sheet 26 is used to adsorb the leg 25. The size of the anti-skid groove is the same as that of the leg 25. When the leg 25 is placed in the anti-skid groove, the sliding of the leg 25 can be restricted. Combined with the adsorption effect of the magnetic sheet 26 on the leg 25, even in the event of accidental contact, the casing 7 can be effectively prevented from falling, thereby ensuring its stability. This design structure is simple and reliable, and is not prone to malfunction or failure. Due to the simple structure of the leg 25, the anti-skid groove and the magnetic sheet 26, the installation, use and maintenance of the casing 7 become relatively simple, reducing the difficulty of use and maintenance costs, and reducing the risk of the casing 7 being damaged.

[0046] In this embodiment, if Figure 2As shown, an air inlet head 37 is sleeved on the surface of the hose 10, and the air inlet head 37 is located between the anti-detachment tube 29 and the hose 10, and the other end of the air inlet head 37 is connected to a warming blanket 4, and a pressure relief nozzle 5 is provided on the warming blanket 4. The pressure relief nozzle 5 can ensure that the air inside the warming blanket 4 is discharged in time, and ensure that the heated air can be continuously delivered to the warming blanket 4 to ensure that the temperature of the warming blanket 4 will not decrease. When the patient uses the warming blanket 4, the patient's body temperature can be continuously maintained, providing the patient with a more stable temperature environment.

[0047] In this embodiment, if Figure 1 As shown, a handle 8 is provided on the upper surface of the casing 7, and the right end of the handle 8 is fixedly connected to the connecting head 9. The handle 8 is arranged in an L shape, and a gap is reserved between the handle 8 and the casing 7, so that the casing 7 can be moved using the handle 8, so that the casing 7 can be used separately from the placement plate 6, and can be used according to the usage scenario.

[0048] In this embodiment, if Figure 2 and Figure 4 As shown, a perforated plate 15 is provided inside the connector 9, and a one-way blade 28 is rotatably connected to the surface of the perforated plate 15, and the one-way blade 28 covers the surface of the perforated plate 15. The perforated plate 15 has two holes through which air can pass. When air enters the connector 9, the air blows open the one-way blade 28, and the one-way blade 28 does not affect the air entering the hose 10. When the fan 21 stops working, the rotatable one-way blade 28 will block the perforated plate 15 in a rotating manner to prevent dust or particles from passing through the perforated plate 15 into the insulation shell 22. The perforated plate 15 has a lower limit protrusion to limit the rotation angle of the one-way blade 28. When the air does not blow open the one-way blade 28, it is ensured that the one-way blade 28 can smoothly block the perforated plate 15.

[0049] In this embodiment, if Figure 2 and Figure 3 As shown, the inner wall of the casing 7 is provided with a card tube 40, a baffle 16 is inserted inside the card tube 40, two plug-in frames 17 are provided on the side of the baffle 16, a filter 18 is inserted inside the plug-in frame 17, and the filter 18 is blocked at the left end of the cylinder shell 20, the card tube 40 has an annular groove inside, and the baffle 16 has a U-shaped pin, which can be plugged with the annular groove of the card tube 40, and the baffle 16 can be rotated, and then the two filters 18 can be switched by rotating the baffle 16, so that the two filters 18 can be used interchangeably.

[0050] In this embodiment, if Figure 3 As shown, a handle 19 is provided on the side of the filter 18, and a strip hole is provided on the surface of the handle 19. A finger can be inserted into the strip hole of the handle 19 to facilitate taking the filter 18 out of the plug-in frame 17 through the handle 19, so that the filter 18 can be cleaned.

[0051] In this embodiment, if Figure 5 and Figure 6 As shown, the surface of the turntable 31 is provided with a knob 32 which is integrally formed with the turntable 31. The turntable 31 can be turned more easily using the knob 32, so that the turntable 31 is more easily stressed, the sealing belt 35 can be better tightened, and the tightening effect on the anti-detachment tube 29 is more obvious.

[0052] In this embodiment, if Figure 2 As shown, a partition 41 is provided inside the insulation shell 22, and a U-shaped air duct is formed between the partition 41 and the insulation shell 22. The heating rod 23 is arranged in a U shape, and the heating rod 23 is installed in the U-shaped air duct, so that the contact time between the air and the heating rod 23 is longer, and the air can be heated more fully.

[0053] Specifically, when in use, the housing 7 is lifted by the handle 8, and the legs 25 of the housing 7 are placed on the placement plate 6, and the magnetic sheet 26 is in contact with the legs 25 to complete the installation and fixation of the housing 7. Under the action of the movable seat 1, the housing 7 can be pushed to move. When the heating device is used, the air inlet head 37 of the heating blanket 4 is put on the hose 10. At this time, the anti-detachment tube 29 is located on the surface of the air inlet head 37. The knob 32 is turned to drive the turntable 31 to rotate. The turntable 31 tightens the two ends of the sealing belt 35, so that the sealing belt 35 tightens the anti-detachment tube 29. The anti-detachment tube 29 hugs the air inlet head 37 to ensure that the air inlet head 37 is not easily separated from the hose 10. The limiting groove 38 on the turntable 31 is stuck by the limiting head 36 on the pressing sheet 33, which can limit the rotation of the turntable 31 and prevent the sealing belt 35 from loosening.

[0054] The fan 21 and the heating rod 23 are controlled by the three-speed wind volume control switch 11 and the three-speed temperature control switch 12, and the corresponding gears are adjusted. The fan 21 draws in external air, and the air enters the interior of the insulation shell 22 after being filtered by the filter 18. The air is heated by the U-shaped heating rod 23 and enters the hose 10. It is then sent to the warming blanket 4 through the hose 10. The hot air increases the temperature of the warming blanket 4, and the patient can maintain body temperature by using the warming blanket 4.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
