Description
Technical Field
[0001] The utility model belongs to the technical field of medical supplies, in particular to a pressure measuring device for an inflatable headgear. Background Art
[0002] Salivary fistula after parotidectomy is one of the most likely complications of parotid tumor surgery. Pressure bandage is required after the operation. The purpose is to use external mechanical pressure to make the skin flap adhere closely to the deep tissue, so that the residual alveoli will shrink under pressure and lose their secretory function, thus avoiding the occurrence of salivary fistula. At the same time, dead space is eliminated to avoid effusion infection, thereby ensuring that the incision achieves primary healing.
[0003] In view of the above situation, an inflatable parotid gland pressure cap is needed to assist in pressure bandaging. It is easy to operate, can adjust local pressure and improve patient comfort. After the inflatable cap is inflated, a pressure test is required. At this time, a pressure measuring device is needed. In actual use, the hose of the existing pressure measuring device is directly inserted into the three-way valve extending from the inflatable cap. Due to the lack of corresponding auxiliary fixing mechanism, the hose and the three-way valve of the pressure measuring device are easily separated during pressure measurement, which will affect the pressure measurement. Therefore, it is necessary to improve this. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] 1. The utility model provides a limit rod, a pressure ring, an inclined rod, a cross plate and a threaded rod. When the first handle is turned, the threaded rod will rotate, so that the cross plate threadedly sleeved with the threaded rod will move along the inner surface of the fixed plate. Since the upper and lower ends of the inclined rod are respectively hinged to the cross plate and the pressure ring, as the cross plate moves, the bottom end of the inclined rod will generate a pulling force on the pressure ring, pulling the two pressure rings to move toward each other along the inner surface of the limit rod, so that the connection between the hose and the three-way valve can be auxiliary clamped and fixed by the pressure ring, thereby improving the stability of the connection between the hose and the three-way valve and preventing it from detaching.

Under the restoring action of the second spring, the triangular block will be completely embedded in the L-shaped slot, thereby locking the position of the pressure plate. When the hose is rolled up around the fixed column, the second handle is pushed to disengage the triangular block and the L-shaped slot. At this time, under the restoring action of the first spring, the pressure plate will return to its original position, thereby realizing the rolling and fixing of the hose.

The left and right sides of the outer surface of the horizontal plate 9 are movably connected with the inner surfaces of the left and right ends of the fixed plate 5 respectively. The inner surface of the middle end of the limiting rod 6 is movably connected with a threaded rod 10. The top end of the threaded rod 10 penetrates the horizontal plate 9 and the fixed plate 5 and extends to the outside of the fixed plate 5 and is fixedly connected with a first handle 11.

[0023] When the first handle 11 is turned, the threaded rod 10 will rotate. Since the outer surface of the threaded rod 10 and the inner surface of the cross plate 9 are threadedly connected, the cross plate 9 will move upward along the inner surface of the fixed plate 5 with the inclined rod 8 under the action of the threaded rod 10, so that the other end of the inclined rod 8 produces a pulling force on the pressure ring 7, pulling the two pressure rings 7 along the outer surface of the limit rod 6 to move toward each other, thereby auxiliary clamping the hose 2, thereby improving the stability of the hose 2 and the three-way valve of the inflatable head cover after being connected, and preventing the hose 2 from detaching and affecting the pressure measurement of the inflatable head cover.
[0024] refer to Figure 1 , Figure 2 and Figure 4 A pressure plate 12 is movably mounted at the bottom of the pressure measuring device body 1 , a fixing column 13 is movably sleeved on the inner surface of the middle end of the pressure plate 12 , and the top of the fixing column 13 is fixedly connected to the bottom of the pressure measuring device body 1 .

[0027] As a technical optimization solution of the present invention, the existence of the slide groove 14 and the slider 15 will limit the movement of the pressing plate 12 and prevent the pressing plate 12 from rotating around the fixed column 13 as the axis.
[0028] refer to Figure 1 , Figure 2 and Figure 4 The bottom end of the outer surface of the fixed column 13 is fixedly sleeved with a fixed block 16, and the top of the fixed block 16 is fixedly installed with a first spring 17 located outside the fixed column 13, and the other end of the first spring 17 is fixedly connected to the bottom end of the pressure plate 12.
[0029] As a technical optimization solution of the present invention, due to the restoring effect of the first spring 17, the first spring 17 will force the pressing plate 12 to return to its original position after the pressing plate 12 moves.
[0030] refer to Figure 4 A short slot 18 is provided at the right end of the fixed block 16, and a vertical rod 19 is movably sleeved at the right end of the short slot 18. A second handle 20 is fixedly installed at the bottom end of the vertical rod 19, and the top end of the second handle 20 is movably connected to the bottom end of the fixed block 16.

[0034] refer to Figure 4 An L-shaped slot 23 located above the triangular block 22 is opened on the right side of the bottom end of the pressing plate 12 , and the width inside the L-shaped slot 23 is equal to the width of the triangular block 22 .
[0035] As a technical optimization solution of the utility model, since the width inside the L-shaped slot 23 is equal to the width of the triangular block 22 , it is ensured that the triangular block 22 can be embedded in the L-shaped slot 23 .
[0036] The working principle and use process of this utility model:
[0037] When the operator is measuring the pressure of the inflatable head cover, he first inserts one end of the three-way valve on the inflatable head cover into the interior of the hose 2, and then turns the first handle 11 to rotate the threaded rod 10. At this time, the cross plate 9 will move upward along the inner surface of the fixed plate 5 under the action of the threaded rod 10, so that the top end of the inclined rod 8 moves along with the cross plate 9, and then the bottom end of the inclined rod 8 generates a pulling force on the pressure ring 7, pulling the two pressure rings 7 to move toward each other along the outer surface of the limit rod 6, thereby auxiliary clamping and fixing the connection between the hose 2 and the three-way valve to prevent the hose 2 from detaching and affecting the pressure measurement.
[0038] After the pressure measurement is completed, the operator moves the pressure plate 12 so that the pressure plate 12 moves along the outer surface of the fixing column 13 and compresses the first spring 17. When the pressure plate 12 contacts the triangular block 22, since the right side of the triangular block 22 is an inclined surface, the triangular block 22 will be squeezed, so that the triangular block 22 moves along the inner surface of the short groove 18 with the vertical rod 19 and compresses the second spring 21. When the triangular block 22 is embedded in the L-shaped slot 23 and aligned with the right side of the L-shaped slot 23, the triangular block 22 will return to its original position under the restoring action of the second spring 21, so that The triangular block 22 is embedded in the right side of the L-shaped slot 23, and the pressure plate 12 will be locked. Then the operator will roll up the hose 2 around the fixing column 13. After the rolling is completed, the second handle 20 is pushed to separate the triangular block 22 from the right side of the L-shaped slot 23, and the locking of the triangular block 22 on the pressure plate 12 is released. At this time, under the restoring action of the first spring 17, the pressure plate 12 will return to its original position, thereby pressing the hose 2. The mutual cooperation of various mechanisms realizes the rolling and fixing of the hose 2, thereby reducing the space occupied by the pressure measuring device and facilitating storage and carrying.
