Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present invention, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.
Referring to fig. 1 and 2, a head fixing pillow for preventing a implant from being displaced after a cornea implantation is provided, which comprises a pillow case 100, wherein a limiting groove 101 for limiting the head of a patient is formed by downwards sinking the middle part of the pillow case 100. Pillow cover 100 is internally filled with a pillow core for providing support for the inside of cushioning reset mechanism 110.
However, if the pillow cover 100 is positioned at both sides of the limit groove 101 and made of hard materials, the head of the patient is difficult to slightly move in the limit groove 101; if the pillow cover 100 is located at two sides of the limit groove 101, if the pillow cover is made of flexible materials, the patient can easily collapse the two sides of the limit groove 101, so that the head of the patient is difficult to automatically reset. To solve this problem, as shown in fig. 2:
the two sides of the pillow case 100 located at the limit groove 101 are flexible parts made of flexible materials such as rubber or cotton cloth, so that the flexible parts can be pressed into the pillow case 100 when the head of a patient rotates; a mounting cavity 102 is formed between the flexible part and the pillow core, a buffer reset mechanism 110 is arranged in the mounting cavity 102, a gas storage cavity 103 for storing compressed gas is arranged at the bottom of the limiting groove 101, and a gas pipeline 120 is arranged between the gas storage cavity 103 and the buffer reset mechanism 110.
Thus, when the head of the patient rotates to apply pressure to the flexible part, the buffer reset mechanism 110 deforms and contracts to enable the flexible part to sink into the pillowcase 100; in the deformation process of the buffer reset mechanism 110, the mounting cavity 102 conveys compressed gas in the gas storage cavity 103 to the buffer reset mechanism 110, so that the buffer reset mechanism 110 drives the flexible part to reset after the flexible part is sunken, and the head of a patient is driven to reset.
That is, when the head of the patient wants to rotate, the flexible portion provides a space for the head to move by being recessed into the pillow case 100, when the head of the patient does not swing automatically, the air pressure is used to drive the flexible portion to push the head of the patient to reset, so that the comfort level of the patient in the sleeping process is improved, and meanwhile, the problem that the corneal endothelium is displaced due to the fact that the head of the patient is always in an inclined state is avoided.
As shown in fig. 2 and 3, the gas pipe 120 includes a gas pipe 121 having one end penetrating into the gas storage chamber 103 and communicating with the gas storage chamber 103, and the other end of the gas pipe 121 is connected to the buffer reset mechanism 110, so as to convey the compressed gas in the gas storage chamber 103 to the buffer reset mechanism 110; and, the outer lane of trachea 121 transversely runs through and is provided with valve pipe 122, and the inside communicates with each other with trachea 121 inside valve pipe 122, and the inside slip of valve pipe 122 is provided with a valve 123, and one end of valve 123 penetrates valve pipe 122 and forms the atress end, is provided with the connecting spring 124 with the two elastic connection between the other end and the inner wall of valve pipe 122 one end. Normally, the valve 123 is positioned at the air pipe 121 to seal the air pipe 121, so that the compressed air in the air storage cavity 103 cannot flow to the buffer reset mechanism 110; when the force-receiving end of the valve 123 is pushed (the specific pushing manner will be described later), the connecting spring 124 is compressed to provide a moving space for the valve 123, so that the valve 123 is forced to move to open the air pipe 121.
In addition, the valve 123 is gradually contracted at both sides of the forced end of the air tube 121 to form a contracted portion 125. This has the advantage that the constriction 125 moves to the air pipe 121 to slowly open the air pipe 121, so that the opening of the air pipe 121 can be adjusted according to the moving distance of the valve 123, thereby achieving the effect of controlling the delivery flow rate.
Moreover, the buffer reset mechanism 110 can be connected with a flow discharging part to discharge the gas entering the buffer reset mechanism 110, so that after the buffer reset mechanism 110 completes pushing and resetting the flexible part, the flexible part is pushed and reset again in a mode of discharging the gas flow, and the multiple use effect is achieved. As shown in fig. 4, the vent member is a vent pipe 130 having one end penetrating through the pillow case 100 and the other end connected to the air receiver 111, so that the gas flow in the buffer reset mechanism 110 is introduced to the outside through the vent pipe 130. And, can also set up the siren 131 in the bleeder tube 130, when gas is discharged through bleeder tube 130, the siren 131 can make a sound to remind the patient, avoid the patient to carry out the head activity frequently carelessly.
In embodiment 1, as shown in fig. 2-4, the buffer reset mechanism 110 includes a gas cylinder 111 and a push plate 114 in the mounting cavity 102, where the gas cylinder 111 is connected to one end of a gas pipe 121 and is used to receive compressed gas in the gas storage cavity 103 through the gas pipe 121, after receiving the gas, one side of the outer ring of the gas cylinder 111, which is close to the flexible portion, is connected to at least one piston tube 112, and a piston rod 113 is slidably disposed inside the piston tube 112, so that the gas in the gas cylinder 111 pushes the piston rod 113 through the piston tube 112. While the push plate 114 is located on the side of the mounting cavity 102 near the flexible portion and is connected to one end of the piston rod 113, so that the push plate 114 pushes the recessed flexible portion back through the piston rod 113. Meanwhile, when the flexible part is extruded by the head of the patient to generate a dent to push the push plate 114 to move, the stressed end of the valve 123 is positioned on the moving path of the push plate 114, so that the push plate 114 pushes the valve 123 through the stressed end in the moving process.
Specifically, both ends of the air cylinder 111 are respectively fixed at both sides of the pillow case 100, so that the buffer reset mechanism 110 is fixedly arranged in the installation cavity 102; second, the push plate 114 is only fixedly connected to the piston rod 113.
Working principle:
when the head of the patient rotates to squeeze the flexible part, the flexible part is sunken and pushes the push plate 114 to move, and meanwhile, the valve 123 moves to open the air pipe 121 because the force bearing end of the valve 123 is positioned on the moving path of the push plate 114, so that the push plate 114 pushes the valve 123 through the force bearing end in the moving process. Then, compressed gas in the gas storage cavity 103 flows into the gas storage cylinder 111 through the gas pipe 121, and pushes the piston rod 113 through the piston pipe 112, so that the piston rod 113 drives the push plate 114 to move and reset, the push plate 114 moves and resets to push the flexible part to reset, and the flexible part resets to push the head of the patient, so that the head of the patient resets.
In the present embodiment, the bleeder tube 130 is in communication with the gas storage cylinder 111, so that the gas in the gas storage cylinder 111 can be discharged through the bleeder tube 130. However, in order to avoid the occurrence of a phenomenon that the gas pressure in the gas storage cylinder 111 is reduced due to the gas leakage of the gas leakage pipe 130 when the piston rod 113 is pushed, the gas leakage pipe 130 is limited in the first step, so that the gas leakage pipe 130 has a smaller gas discharge amount than the gas intake amount in the gas storage cylinder 111, that is, the pipe diameter of the gas leakage pipe 130 is smaller than the pipe diameter of the gas pipe 121, and the gas pipe 121 is always in a high pressure state in the gas storage cylinder 111 during the gas transmission to the gas storage cylinder 111. Secondly, an inserted link 132 is arranged at one end of the piston rod 113 close to the bleeder 130, the size of the inserted link 132 is matched with that of the bleeder 130, meanwhile, one end of the inserted link 132 penetrates into the bleeder 130 to seal the bleeder 130, and only after the push plate 114 pushes the flexible part to reset, the inserted link 132 is separated from the bleeder 130, and at the moment, the gas in the gas storage cylinder 111 can be discharged through the bleeder 130.
In embodiment 2, the present embodiment is optimized based on embodiment 1, and as shown in fig. 5 and 6, a pad 140 is disposed above the limiting groove 101, and the pad 140 is elastically connected with the limiting groove 101 through elastic connection portions 141 on both sides. Meanwhile, a driving part is further arranged at the bottom of the backing plate 140 and is positioned on the reciprocating path of the push plate 114, and in the reciprocating process of the push plate 114, the driving part drives the backing plate 140 to move upwards by using the moving force of the push plate 114 so as to remind a patient.
In the above, the driving part specifically includes a wedge block 142 fixed at the bottom of the backing plate 140, and a driven rod 143 having one end laterally slid into the mounting cavity 102 and the other end fixedly connected with a push block 144, the driven rod 143 penetrating into the top of the mounting cavity 102 is rotatably provided with an elastic plate 145, one side of the elastic plate 145 is provided with a baffle 146 fixed at the top of the driven rod 143, and the other side is provided with an elastic piece 147 fixed at the top of the driven rod 143.
Working principle: the top end of the elastic plate 145 extends into the moving path of the push plate 114, in the process that the push plate 114 is pushed by the flexible part to move, the bottom of the push plate 114 pushes the elastic plate 145, the elastic plate 145 rotates through deformation of the elastic plate 147, so that the push plate 114 moves beyond the elastic plate 145, when the push plate 114 is pushed by the piston rod 113 to reset, the push plate 114 pushes the elastic plate 145 to the baffle 146 to rotate but is blocked by the baffle 146, so that the driven rod 143 is driven to move, the push block 144 at one end of the driven rod 143 pushes the base plate 140 upwards through the inclined surface of the wedge block 142, and when the push block 144 pushes the wedge block 142 to a force greater than the elastic deformation force of the elastic plate 145, the elastic plate 145 enables the push plate 114 to cross the elastic plate 145 through elastic bending deformation, so that reset is realized, and next work is carried out.
Therefore, the flexible part can provide a temporary movable space for the head of the patient in the groove and resetting process, and can drive the cushion plate 140 to move in the resetting process, so that the cushion plate 140 lifts the head of the patient to wake up the patient, and the patient is reminded.
In embodiment 3, further optimization is continued on the basis of embodiment 1, as shown in fig. 7, the outer ring of the air cylinder 111 is rotated to have a bracket 115 fixed inside the pillow case 100, two sides of the bottom end of the push plate 114 are rotatably disposed in two sides of the pillow case 100, and meanwhile, the push plate 114 is rotatably connected with the piston rod 113. Thus, when the flexible portion is depressed to push the push plate 114, the push plate 114 rotates through the portion of the bottom end rotationally connected to the two sides of the buffer reset mechanism 110, and the push plate 114 rotates to drive the air cylinder 111 to rotate through the hinge connection with the piston rod 113, so that the mode of resetting the flexible portion is changed.
That is, by means of the rotational arrangement, the transverse reciprocation of the push plate 114 is changed to rotational reciprocation which is more consistent with the return of the patient's head during operation, so as to enhance patient comfort.

Further, a support member for supporting the expansion of the balloon 150 is provided at the balloon 150. The support member may be a support spring 152 provided inside the balloon 150, or may be a relief valve 133 provided inside the relief tube 130, and one end of the relief tube 130 communicates with the balloon 150. When the support member is a support spring 152, the support spring 152 supports the airbag 150 in a normal state; when the support member is the pressure release valve 133, the pressure release valve 133 always allows a certain amount of gas to exist in the airbag 150, and the airbag 150 is inflated by the gas.
In the working principle, the supporting component in the air bag 150 is supported under normal state, when the head of a patient extrudes the flexible part, the flexible part is sunken to drive the connecting plate 151 to move and simultaneously extrude the air bag 150, and the air bag 150 is extruded to be in a compressed state, so that the flexible part can be sunk into the mounting cavity 102. At the same time, the connecting plate 151 pushes the valve 123 to open the air pipe 121, at this time, the air in the air storage chamber 103 is delivered into the air bag 150 through the air pipe 121, at this time, the air bag 150 is inflated to jack up the elastic part for resetting.
In summary, the movement and the resetting of the head of the patient are realized by the compression and the expansion of the air bag 150, so that the flexible part and the air bag 150 can be attached to the head of the patient, thereby further improving the comfort level of the patient.
