Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an air outlet direction adjustment structure for a heating blanket main unit. Background Technology

[0002] In the medical field, in operating rooms, post-anesthesia recovery rooms, intensive care units, and other similar settings, patients may experience a decline in their thermoregulation ability due to surgical trauma, operation duration, medication effects, and individual physical conditions, making them highly susceptible to hypothermia. This not only affects the patient's postoperative recovery process but may also trigger a series of complications, such as coagulation disorders and cardiovascular events, seriously threatening the patient's life and health. In such cases, medical staff will use warming blankets to raise and keep the patient warm, in order to maintain a stable body temperature, reduce the risks associated with hypothermia, and improve medical safety and patient comfort. Heating blankets are common medical devices, mainly consisting of a blanket body and a main unit for heating the blanket body. The two are used together, as disclosed in the utility model patent with announcement number CN205758801U. However, in actual application, the number of blanket bodies that can be matched with one main unit is limited. In order to make full use of the device, medical staff will use the heating blanket main unit separately by inserting its air outlet under the quilt or blanket covering the patient to provide warm air to the patient. However, the existing air outlet can only blow air in one direction. Over time, the area facing that direction can easily accumulate too much heat or even become hot, reducing the patient's comfort. Utility Model Content

[0003] This utility model provides an air direction adjustment structure for the air outlet of a heating blanket main unit. It achieves flexible adjustment of the hot air blowing direction by rotating and setting an air direction control plate at the air outlet of the air outlet.

[0004] To achieve these and other advantages according to the present invention, a structure for adjusting the airflow direction at the outlet of the air supply duct of a heating blanket main unit is provided, comprising:

[0005] The air supply duct has a rotating shaft that is perpendicular to its axis and is rotatably installed near its outlet end. A circular air direction control plate that is parallel to the shaft and has a diameter slightly smaller than the inner diameter of the air supply duct is installed on the rotating shaft.

[0006] Preferably, in the air outlet air direction adjustment structure of the heating blanket host, a protective cover is provided on the outer wall of the air supply pipe, a drive motor is provided inside the protective cover, a drive gear is provided on the output shaft of the drive motor, one end of the rotating shaft rotates through the limiting hole on the side wall of the air supply pipe and extends into the protective cover, and is provided with a driven gear that meshes with the drive gear.

[0007] Preferably, in the air outlet air direction adjustment structure of the heating blanket host, a limit frame is provided inside the protective cover, the drive motor is provided on the limit frame, the limit frame rotatably abuts against one end of the rotating shaft, and the other end of the rotating shaft is rotatably inserted into the limit groove on the inner side wall of the air supply pipe.

[0008] Preferably, in the air outlet air direction adjustment structure of the heating blanket main unit, an operation hole is provided on the side wall of the protective cover, and a rechargeable mobile power supply is provided on the limiting frame inside the protective cover. The charging port of the mobile power supply and the control switch of the drive motor are located at the operation hole, and the mobile power supply and the control switch are both electrically connected to the drive motor.

[0009] Preferably, in the air outlet air direction adjustment structure of the heating blanket main unit, a protective cover can be detachably installed at the operation hole to cover it.

[0010] Preferably, in the air outlet direction adjustment structure of the heating blanket main unit, a support frame is provided at the outlet end of the air outlet, and the support frame includes: a support ring, which is coaxially arranged with the air outlet; and multiple support rods, one end of which is connected to the support ring and the other end of which is connected to the air outlet.

[0011] Preferably, in the air outlet air direction adjustment structure of the heating blanket main unit, the diameter of the support ring is not less than the diameter of the air outlet duct.

[0012] Preferably, in the air outlet air direction adjustment structure of the heating blanket main unit, the number of support rods is not less than three.

[0013] This invention offers at least the following advantages: The air supply duct has a rotating shaft rotatably positioned near its outlet end, perpendicular to its axis. A circular airflow control plate, parallel to the shaft and with a diameter slightly smaller than the inner diameter of the air supply duct, is mounted on the shaft. Rotation of the shaft drives the airflow control plate to rotate, thus flexibly changing the direction of the hot air at the air supply duct outlet. This effectively prevents excessive heat accumulation or even overheating of the area facing the air supply duct after prolonged blowing in one direction. Furthermore, continuously changing the airflow direction improves airflow efficiency, ensuring even heating of the patient's surroundings and enhancing patient comfort. This invention also eliminates the need for constant replacement of the heating components, ensuring even heating of the patient's body.

[0014] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] like Figure 1 , Figure 2 As shown, this utility model provides a structure for adjusting the airflow direction at the outlet of the air supply duct of a heating blanket main unit, comprising:

[0022] The air supply duct 9 has a rotating shaft 15 that is perpendicular to its axis and is rotatably installed near its outlet end. A circular wind direction control plate 11 that is parallel to the rotating shaft 15 and has a diameter slightly smaller than the inner diameter of the air supply duct 9 is installed on the rotating shaft 15.

[0023] The airflow direction adjustment structure of the heating blanket main unit provided by this technical solution is mainly located inside the air supply pipe 9. A rotating shaft 15 is rotatably installed near the outlet end of the air supply pipe 9, perpendicular to the axis of the air supply pipe 9. A circular airflow direction control plate 11 parallel to the rotating shaft 15 is installed on the rotating shaft 15. In order to allow the airflow direction control plate 11 to rotate freely inside the air supply pipe 9 and to adjust the airflow direction more fully, the diameter of the airflow direction control plate 11 is slightly smaller than the inner diameter of the air supply pipe 9.

[0024] The working principle of the air direction adjustment structure of the air supply duct outlet of the heating blanket main unit provided by this technical solution is as follows: the rotating shaft 15 rotates and drives the air direction control plate 11 to rotate. When the hot air in the air supply duct 9 blows towards the outlet and towards the air direction control plate 11, the hot air undergoes diffuse reflection at the air direction control plate 11 and changes the air direction. The direction changes continuously as the air direction control plate 11 rotates.

[0025] This utility model includes at least the following beneficial effects: Inside the air supply duct 9, near its outlet end, there is a rotating shaft 15 perpendicular to its axis. A wind direction control plate 11 parallel to it is provided on the rotating shaft 15. The rotation of the rotating shaft 15 can drive the wind direction control plate 11 to rotate, thereby flexibly changing the direction of the hot air at the outlet of the air supply duct 9. This effectively avoids the air supply duct 9 blowing air in one direction for a long time, causing excessive heat to accumulate or even become hot in that direction. Moreover, constantly changing the wind direction can improve the air flow efficiency, making the air around the patient evenly heated, thereby improving the patient's comfort. The wind direction control plate 11 is a circle with a diameter slightly smaller than the inner diameter of the air supply duct 9, which not only allows the wind direction control plate 11 to rotate freely inside the air supply duct 9 but also allows for more complete adjustment of the wind direction.

[0026] In another technical solution, such as Figure 1 As shown, in the airflow direction adjustment structure of the air supply duct outlet of the heating blanket main unit, a protective cover 2 is provided on the outer wall of the air supply duct 9. A drive motor 6 is provided inside the protective cover 2. A drive gear 8 is provided on the output shaft of the drive motor 6. One end of the rotating shaft 15 rotates through the limiting hole 14 on the side wall of the air supply duct 9 and extends into the protective cover 2, and is provided with a driven gear 1 that meshes with the drive gear 8. The drive motor 6 drives the drive gear 8 to rotate, which in turn drives the driven gear 1 and the rotating shaft 15 to rotate. The mechanical drive is more labor-saving and convenient. The diameter of the limiting hole 14 is slightly larger than the diameter of the rotating shaft 15, so that the rotating shaft 15 rotates at the limiting hole 14 but does not move arbitrarily. The diameter of the driven gear 1 is larger than that of the drive gear 8, so that the rotating shaft 15 rotates at a low speed, avoiding the rotation of the airflow direction control plate 11 too fast and failing to achieve the effect of adjusting the airflow direction. The protective cover 2 prevents the operation of the drive motor 6, drive gear 8, and driven gear 1 inside from being interfered with by the outside world, and can also prevent dust and reduce noise.

[0027] In another technical solution, such as Figure 1As shown, in the airflow direction adjustment structure of the air supply duct outlet of the heating blanket main unit, a limiting bracket 7 is provided inside the protective cover 2. The driving motor 6 is mounted on the limiting bracket 7. One end of the limiting bracket 7 rotatably abuts against the rotating shaft 15, and the other end of the rotating shaft 15 is rotatably inserted into the limiting groove 10 on the inner side wall of the air supply duct 9. The limiting bracket 7 is used to fix and support the driving motor 6; the limiting bracket 7 and the limiting groove 10 cooperate to clamp the rotating shaft 15 in the middle, preventing the rotating shaft 15 from moving arbitrarily in its axial direction.

[0028] In another technical solution, such as Figure 1 As shown, in the airflow direction adjustment structure of the air outlet of the heating blanket main unit, an operation hole 4 is provided on the side wall of the protective cover 2. A rechargeable mobile power supply 5 is provided on the limiting frame 7 inside the protective cover 2. The charging port of the mobile power supply 5 and the control switch of the drive motor 6 are located at the operation hole 4. The mobile power supply 5 and the control switch are both electrically connected to the drive motor 6. The limiting frame 7 can also be used to fix and support the mobile power supply 5; the mobile power supply 5 supplies power to the drive motor 6, and the operation hole 4 facilitates charging the mobile power supply 5 and operating the control switch.

[0029] In another technical solution, in the air outlet direction adjustment structure of the heating blanket main unit, a wiring hole is provided on the side wall of the protective cover, and the drive motor is connected to an external power supply and controller via an electrical connection wire. The electrical connection wire passes through the wiring hole to connect the drive motor and the external power supply and controller; the external power supply can be a fixed power supply or a mobile power supply, which supplies power to the drive motor and controller, and the controller is used to control the operating status of the drive motor.

[0030] In another technical solution, such as Figure 1 , Figure 2 As shown, in the airflow direction adjustment structure of the air outlet of the heating blanket main unit, a protective cover 3 is detachably installed at the operation hole 4 to cover it. For example, one end of the protective cover 3 is hinged to the protective cover 2, and the other end is connected to the protective cover 2 via a bayonet structure; or the protective cover 2 at the operation hole 4 has a hook side for Velcro, and the protective cover 3 has a rough side for Velcro; the protective cover 3 prevents the control switch from being accidentally activated.

[0031] In another technical solution, such as Figure 1 , Figure 2 As shown, in the air outlet direction adjustment structure of the heating blanket main unit, a support frame is provided at the outlet end of the air supply pipe 9, and the support frame includes:

[0032] A support ring 12 is coaxially arranged with the air supply pipe 9, and the distance between the support ring 12 and the air supply pipe 9 is greater than the radius of the air direction control plate 11;

[0033] Multiple support rods 13 are provided, one end of which is connected to the support ring 12 and the other end to the air supply duct 9. The support frame is used to support the quilt or blanket covering the air supply duct 9 and prevent the quilt or blanket from touching the air direction control plate 11 and affecting the rotation of the air direction control plate 11; multiple support rings 13 are provided to ensure the stable support of the support ring 12.

[0034] In another technical solution, in the air direction adjustment structure of the air outlet of the heating blanket main unit, the diameter of the support ring is not less than the diameter of the air outlet. This prevents the blanket or quilt covering the air outlet from being too low and touching the air direction control plate, thus affecting the rotation of the air direction control plate.

[0035] In another technical solution, the number of support rods in the air outlet direction adjustment structure of the heating blanket main unit is no less than three. Too few rods will prevent the blanket or quilt from being fully expanded to provide sufficient space for the air direction control plate to move freely, thus affecting the free rotation of the air direction control plate. Preferably, the number of support rods is no less than three.

[0036] The number of devices and processing scale described herein are for the purpose of simplifying the description of this utility model. Applications, modifications, and variations of this utility model will be readily apparent to those skilled in the art.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
