Detailed implementation manners
[0023] The present utility model will be further described below with reference to specific drawings and embodiments.
[0024] Embodiment 1
[0025] As Figures 1 to 6 shown, Embodiment 1 discloses a cardiopulmonary resuscitation assistance device for pregnant and lying-in women, which mainly consists of components such as an auxiliary support plate 1, a support base 2, a strut 3, a strut lock 4, and a locking pin 5.
[0026] When in use, the auxiliary support plate 1 is placed under the patient. A set of height adjustment support mechanisms are installed at both ends of one side of the auxiliary support plate 1. This side of the auxiliary support plate 1 can be supported and lifted to an appropriate height through the height adjustment support mechanism, so that the pregnant woman can maintain a body posture with a 27-degree to 30-degree left inclination during cardiopulmonary resuscitation, achieving the purpose of reducing venous return obstruction and reducing cardiac output.
[0027] In this Embodiment 1, the height adjustment support mechanism mainly consists of a support base 2, a strut 3, and a strut lock 4. A locking pin 5 is installed on the side of the auxiliary support plate 1. A card slot 2a is provided on the back of the support base 2, and the support base 2 is connected in cooperation with the locking pin 5 through the card slot 2a; a vertical strut placement groove is provided on the front of the support base 2, and the strut 3 is installed in the strut placement groove and can be adjusted in position. The strut lock 4 is installed on the front of the support base 2, and the strut lock 4 is used to lock and fix the adjusted strut 3. When in use, the support base 2 is installed on the side of the auxiliary support plate 1 through the cooperation of the card slot 2a and the locking pin 5. Adjust the orientation of the support base 2 to make the strut 3 stand vertically. Then open the strut lock 4, adjust the support height of the strut 3 to make the auxiliary support plate 1 have a 27-degree to 30-degree left inclination, and then use the strut lock 4 to lock and fix the strut 3. In this way, the patient can maintain a body posture with a 27-degree to 30-degree left inclination during cardiopulmonary resuscitation.
[0028] In Embodiment 1, the locking pin 5 is T-shaped, including a pin head 5a with a circular cross-section and a pin post portion 5b with a square cross-section; the card slot 2a is T-shaped, both ends of the card slot 2a are closed, the opening width of the card slot 2a is adapted to the pin post portion 5b, and a circular fitting hole 2b for the pin head 5a to be inserted is provided in the middle of the card slot 2a. With such a setting, when the height-adjustable support mechanism is in use, the support rod 3 plays a vertical supporting role, the locking pin 5 is located at the lower end of the card slot 2a, and the square pin post portion 5b of the locking pin 5 is placed in the opening of the card slot 2a in a way that it can slide but not rotate. Therefore, the support base 2 can be kept stable at the position of the auxiliary support plate 1, and the support rod 3 installed in the support base 2 can also be kept stable during support. When the height-adjustable support mechanism is not in use, push and pull the support rod 3 to drive the support base 2 to move. When the support base 2 moves to a position where the circular fitting hole 2b corresponds to the locking pin 5, the support base 2 can be removed, realizing the disassembly of the height-adjustable support mechanism, and the height-adjustable support mechanism is only installed when in use.
[0029] In addition, the cross-section of the pin post portion 5b is preferably set as a square, so that when the height-adjustable support mechanism is not used for a short time, it can be folded and placed on the side of the auxiliary support plate 1. The folding and storage method is as follows: when the height-adjustable support mechanism is not in use, push and pull the support rod 3 to drive the support base 2 to move. When the support base 2 moves to a position where the circular fitting hole 2b corresponds to the locking pin 5, drive the support base 2 to rotate 90 degrees through the support rod 3, so that the support rod 3 is placed horizontally on the side of the auxiliary support plate 1, and then push or pull the support rod 3 to make the square pin post portion 5b of the locking pin 5 located at one end of the opening of the card slot 2a. At this time, the horizontally placed support rod 3 cannot rotate and is folded on the side of the auxiliary support plate 1.
[0030] In Embodiment 1, the support rod lock 4 includes a cam post 4a and a lever handle 4b. Two pin hooks 2c are symmetrically provided on two edges of the support rod placement groove. The cam post 4a is rotatably installed in the pin hooks 2c, and the lever handle 4b is installed on the cam post 4a. During use, drive the cam post 4a to rotate through the lever handle 4b, so that the distance between the surface of the cam post 4a and the bottom of the support rod placement groove changes, thereby realizing the locking and release of the support rod 3.
[0031] Embodiment 2
[0032] As Figure 7 shown, Embodiment 2 discloses a cardiopulmonary resuscitation assistance device for pregnant and lying-in women, which is different from Embodiment 1 in that the support rod lock 4 is further provided with a safety pin 6, a plurality of pin holes 3a for the safety pin 6 to be inserted are provided on the support rod 3, and a through pin hole for the safety pin 6 to pass through is provided on the lever handle 4b.
[0033] During specific use, after the support rod 3 is locked by the cam post 4a, insert the safety pin 6 into the pin hole 3a through the through pin hole, which can further improve the safety after the support rod 3 is locked.
[0034] In the second embodiment, the cross-sectional shape of the safety pin 6 is wedge-shaped, and the shapes of the pin hole 3a and the through pin hole are adapted to the cross-sectional shape of the safety pin 6. Such a shape structure can keep the safety pin 6 stable and non-shaking in the pin hole 3a and the through pin hole. The safety pin 6 is connected to the support base 2 by a thin string 7 to prevent loss and facilitate access.
[0035] The above-described are only the preferred embodiments of the present invention, and the above specific embodiments are not limitations on the present invention. Various deformations and modifications can occur within the technical concept scope of the present invention. Any retouching, modification, or equivalent replacement made by those of ordinary skill in the art according to the above description shall fall within the protection scope of the present invention.
