[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0021] As attached Figure 1-5The device for maintaining intracranial pressure after craniotomy shown in the figure comprises a first supporting leg 1, a convex limiting clamping plate 3 is provided on the upper front end of the outer surface of the first supporting leg 1, a plurality of fixing grooves 4 are provided on the upper part of the outer surface of the first supporting leg 1, a second supporting leg 2 is provided on the rear end of the first supporting leg 1, a first adjusting screw 5 is provided on the lower part of the side close to the outer surface of the first supporting leg 1 and the second supporting leg 2, a movable block 6 is sleeved and installed on the outer surface of the first adjusting screw 5, a first locking nut 7 is sleeved and installed on the outer surface of the first adjusting screw 5, and the first locking nut 7 is located on the front end of the outer surface of the movable block 6.
[0022] A support frame 8 is movably installed on the upper rear end of the outer surface of the first supporting leg 1, and a support frame 9 is movably installed on the lower rear end surface of the support frame 8 and the upper surface of the movable block 6. A second adjusting screw 10 is commonly provided at the middle of the front end and the rear end of the inner surface of the support frame 8, and a second locking nut 11 is sleeved on the outer surface of the second adjusting screw 10.
[0023] A U-shaped pillow 12 is sleeved and installed on the outer surface of the second adjusting screw 10, and the second locking nut 11 is located at the rear end of the outer surface of the U-shaped pillow 12. An adjustment groove 13 is opened in the middle of one side of the outer surface of the U-shaped pillow 12, and the diameter of the groove of the adjustment groove 13 is equal to the diameter of the second adjusting screw 10. A pad net 14 is pasted and installed on the upper surface of the U-shaped pillow 12, and a plurality of air holes are evenly opened on the upper surface of the pad net 14. Matching Velcro components 15 are commonly provided at both ends of the outer surface of the pad net 14 and both ends of the upper surface of the U-shaped pillow 12. The Velcro component 15 includes Velcro adhesive strips and Velcro velvet strips.
[0024] During operation, the limiting clamp plate 3 provided on the first supporting leg 1 can first be connected to the patient's bed railing by being clamped together. At this time, a fixing tool such as a cable tie can be used to wrap it around the fixing groove 4 provided on the first supporting leg 1 and wrap it around the bed railing to connect it. In this case, the device and the patient's bed can be fixedly connected and installed.
[0025] Secondly, when the device and the patient's bed are connected and installed with each other, the movable block 6 can be pushed to move laterally by turning the first locking nut 7 set on the first adjusting screw 5 clockwise. When the movable block 6 moves laterally, the support frame 9 can be adjusted from the inclined state to the upright state, so that the rear end of the support frame 8 can be controlled to be lifted in an inclined state by using the support frame 9 adjusted in the upright state. When the support frame 8 is adjusted to a suitable inclined height, the turning of the first locking nut 7 can be stopped. In this case, the first locking nut 7 can limit and fix the movable block 6 to maintain the stability of the inclined and lifted state of the support frame 8.
[0026] When the support frame 8 is tilted and lifted, the U-shaped pillow 12 can be controlled to rotate relative to the second adjusting screw 10 through the adjustment slot 13 provided on the U-shaped pillow 12, so as to achieve the effect of adjusting the opening direction of the U-shaped pillow 12. When the opening direction of the U-shaped pillow 12 is lateral, the second locking nut 11 can be moved on the second adjusting screw 10 to complete the locking and fixation of the U-shaped pillow 12. At this time, the patient's head can be placed sideways on the U-shaped pillow 12, and the patient's head can be supported by the closed end of the U-shaped pillow 12 to maintain the stability of the patient's head sideways. In this case, the patient's head will be higher than the body during the process of lying flat, so as to facilitate better reflux of the intracranial veins, which is beneficial to reduce the condition of cerebral edema, thereby maintaining the stability of the patient's intracranial pressure and facilitating the discharge of secretions in the patient's respiratory tract.
[0027] When the patient lies on the U-shaped pillow 12 sideways, his head will rest on the pad net 14. Since the pad net 14 is provided with a plurality of ventilation holes, the patient's head can be easily ventilated, which is beneficial to the patient's recovery and can reduce the phenomenon of bed sores on the head. At the same time, an opening is provided on the U-shaped pillow 12, which can be exposed by separating the pad net 14 from the U-shaped pillow 12. At this time, the U-shaped pillow 12 can be separated from the second adjusting screw 10 through the opening, so as to facilitate the replacement of different types of U-shaped pillows 12 for use, which is beneficial to adjust the use for patients of different body shapes, thereby improving the applicability of the device.
[0028] In summary: the maintenance device can achieve the effect of maintaining the patient's intracranial pressure stable by adopting a special resting position, which is beneficial to the patient's recovery and can reduce the phenomenon of bedsores on the head.
[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
