Description

TECHNICAL FIELD

[0001] The utility model relates to a head cooling device for clinical nursing. BACKGROUND

[0002] Head cooling is an important means of auxiliary treatment for fever, craniocerebral injury, stroke patients and the like, and by reducing the brain temperature, brain cell metabolism can be effectively reduced, cerebral edema can be reduced, intracranial pressure can be reduced, and the prognosis recovery of the patient has a positive effect. However, the existing head cooling devices on the market generally have significant technical defects. Most of the existing head cooling devices adopt a single-point cooling design mode for a single part, such as cooling treatment for only the forehead or the back of the head. Although this design can achieve a certain degree of local cooling effect, it cannot perform cyclic cooling on the whole head or a larger range.

[0003] More importantly, the single position of the head is continuously subjected to low-temperature stimulation for a long time, which can cause a series of serious complications. For example, long-term low-temperature stimulation can cause local skin frostbite, abnormal vasoconstriction, and even cause local tissue ischemia and hypoxia, causing secondary injury to the patient. At the same time, single-position cooling cannot effectively balance the overall temperature of the head, which is not conducive to maintaining the stability of the brain physiological environment, and reduces the effectiveness and safety of cooling treatment. In view of this, a head cooling device for clinical nursing is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL

[0004] In view of the deficiencies of the prior art, the utility model provides a head cooling device for clinical nursing to solve the technical problems that the existing head cooling devices can only cool a single position and cannot perform cyclic cooling within a certain range of the head, and a series of complications are caused after the single position of the head is subjected to low-temperature stimulation for a long time, thereby reducing the practical value of the existing cooling device.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme, a head cooling device for clinical nursing, comprising: A shell is provided with a fixing belt at both ends, and an arc-shaped frame is arranged inside, a plurality of first ventilation grooves are formed on the shell; An activity board is provided with an arc-shaped frame, the arc-shaped frame is slidingly arranged on the arc-shaped frame, and a fan driven to rotate by a motor is arranged on the activity board; A driving mechanism is arranged on the activity board and connected with the shell to drive the activity board to reciprocally slide along the arc-shaped frame; and A baffle is arranged on the opening side of the shell, and an installation assembly is arranged on the baffle, and an ice bag is installed through the installation assembly.

[0006] In a preferred embodiment, the drive mechanism includes: A drive gear is rotatably mounted on the movable plate along its axis, and a servo motor is mounted on the movable plate to drive the drive gear to rotate forward and backward. A rack, which is vertically movable, is disposed within the housing; when raised, the rack can mesh with the drive gear. A control component, disposed on the rack and connected to the housing, is provided to selectively control the raising and lowering of the rack.

[0007] In a preferred embodiment, the housing is provided with two sets of mounting posts, and each end of the rack is provided with a connecting sleeve, and the two sets of connecting sleeves are slidably sleeved on the two sets of mounting posts respectively.

[0008] In a preferred embodiment, the control component includes: The elastic element has one end abutting against the connecting sleeve and the other end abutting against the arc-shaped frame; A connecting ring, rotatably fitted onto the connecting sleeve, and a lever provided on the connecting ring; and A hook-shaped groove is formed on the housing, and the lever is engaged in the hook-shaped groove and extends out of the housing.

[0009] In a preferred embodiment, the lever is provided with a button, and the housing is provided with a control switch for controlling the start and stop of the servo motor. When the lever is raised, the button can abut against the control switch.

[0010] In a preferred embodiment, a flexible pad is provided on one side of the housing.

[0011] In a preferred embodiment, the mounting assembly includes a mounting shell disposed on one side of the baffle, the mounting shell having an opening at the top for placing an ice pack and a drainage hole at the bottom, and multiple sets of second ventilation slots on the sidewall of the mounting shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In use, the device's housing is secured to the patient's head with a strap. An ice pack is mounted on one side of a baffle using an assembly. A motor drives a fan to rotate, blowing the cold air generated by the ice pack through a first ventilation slot onto the patient's skin to cool the head. When spot cooling causes side effects, a drive mechanism can control a movable plate to slide back and forth along an arc-shaped frame, causing the fan to reciprocate in an arc within the housing. This cyclical cooling of the patient's head effectively prevents discomfort caused by spot cooling, eliminates the side effects of traditional spot cooling, and enhances the device's practical value.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0016] Example: like Figs. 1-3 As shown, this utility model provides a head cooling device for clinical nursing, including a shell 1, with fixing straps 7 at both ends, an arc-shaped frame 2 inside, multiple sets of first ventilation slots 3 on the shell 1, a movable plate 13 inside the shell 1, an arc-shaped frame 14 on the movable plate 13, the arc-shaped frame 14 slidingly fitted on the arc-shaped frame 2, a fan 16 driven to rotate by a motor 15 on the movable plate 13, a flexible pad 8 on one side of the shell 1, a baffle 9 on the open side of the shell 1, and a mounting assembly on the baffle 9 for mounting ice packs. The mounting assembly includes a mounting shell 10 on one side of the baffle 9, an opening for placing ice packs at the top of the mounting shell 10, a drainage hole 12 at the bottom, and multiple sets of second ventilation slots 11 on the side wall of the mounting shell 10.

[0017] In use, the device can be secured to the patient's head using the fixing strap 7. An ice pack is placed inside the mounting shell 10, cooling the air inside. Then, the motor 15 is activated, blowing cold air onto the patient's head, effectively preventing frostbite from direct ice application. The arrangement of the first ventilation slot 3 and the second ventilation slot 11 allows the shell 1 to communicate with the outside air, facilitating airflow. Furthermore, the flexible pad 8 does not obstruct the first ventilation slot 3, improving user comfort.

[0018] like Fig. 2 , 3 As shown, in this embodiment, a drive mechanism connected to the housing 1 is provided on the movable plate 13. The drive mechanism drives the movable plate 13 to slide back and forth along the arc frame 2. The drive mechanism includes a drive gear 18 that is rotatably provided on the movable plate 13 along its axis. A servo motor 17 that can control the forward and reverse rotation of the drive gear 18 is provided on the movable plate 13. A rack 19 that can be raised and lowered is provided inside the housing 1. After the rack 19 is raised, it can mesh with the drive gear 18.

[0019] When cyclic cooling is required, the rack 19 can be raised to engage with the drive gear 18, and then the servo motor 17 can be activated to drive the drive gear 18 to rotate forward and backward, thereby causing the movable plate 13 to reciprocate along the arc frame 2. It is understood that the forward and reverse rotation control of the servo motor 17 is a common technique in this field and will not be elaborated upon here. Additionally, two sets of mounting posts 4 are provided inside the housing 1, and connecting sleeves 20 are provided at both ends of the rack 19. The two sets of connecting sleeves 20 are slidably fitted onto the two sets of mounting posts 4, and the movement of the rack 19 is positioned by the cooperation of the mounting posts 4 and the connecting sleeves 20, so that the rack 19 can stably engage with the drive gear 18 after rising.

[0020] like Fig. 2 , 3 As shown, in this embodiment, the drive mechanism further includes a control component disposed on the rack 19 and connected to the housing 1. The control component can selectively control the raising and lowering of the rack 19. The control component includes an elastic element 21, one end of which abuts against the connecting sleeve 20 and the other end against the arc-shaped frame 2. A connecting ring 22 is rotatably fitted on the connecting sleeve 20, and a lever 23 is disposed on the connecting ring 22. A hook-shaped groove 6 is provided on the housing 1, and the lever 23 is engaged in the hook-shaped groove 6 and extends out of the housing 1.

[0021] When the rack 19 is in an ascending state and meshes with the drive gear 18, the elastic element 21 applies an upward thrust to the rack 19, ensuring stable meshing of the rack 19 with the drive gear 18. Furthermore, when targeted cooling is required, the lever 23 can be moved along the hook-shaped groove 6, causing the connecting sleeve 20 to move and compress the elastic element 21. Then, rotating the lever 23 causes the connecting ring 22 to rotate on the connecting sleeve 20. Finally, releasing the lever 23, under the action of the elastic element 21, causes the lever 23 to engage at the other end of the hook-shaped groove 6, allowing the rack 19 to disengage from the drive gear 18. The movable plate 13 can then remain stationary under the friction between the arc-shaped frame 14 and the arc-shaped bracket 2, thus achieving targeted cooling. This structural arrangement allows for free switching between targeted cooling and cyclic cooling, with convenient and quick switching.

[0022] like Fig. 2 , 3 As shown, in this embodiment, a button 24 is provided on the lever 23, and a control switch 5 for controlling the start and stop of the servo motor 17 is provided inside the housing 1. After the lever 23 is raised, the button 24 can abut against the control switch 5. By moving the lever 23 in the opposite direction, the rack 19 will be driven to rise under the action of the elastic element 21, and the control switch 5 will be triggered, so that the servo motor 17 can be started. There is no need to control the start and stop of the servo motor 17 separately, making the device more convenient to use.

[0023] The specific usage and beneficial effects of this utility model are as follows: In use, the device secures the housing 1 to the patient's head via the fixing strap 7. An ice pack is mounted on one side of the baffle 9 using the mounting assembly. The fan 16 is driven by the control motor 15 to rotate, blowing the cold air generated by the ice pack onto the patient's skin through the first ventilation slot 3 to cool the patient's head. When fixed-point cooling causes side effects to the patient, the movable plate 13 can be controlled by the drive mechanism to slide back and forth along the arc frame 2, thereby driving the fan 16 to make arc-shaped reciprocating motions within the housing 1, thus circulating cooling of the patient's head. This effectively prevents discomfort caused by fixed-point cooling, eliminates the side effects of traditional fixed-point cooling, and improves the practical value of the device.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
