[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] Referring to Figure 1 、 Figure 2 and Figure 4 A negative pressure drainage and irrigation device for ophthalmic care provided by the present invention includes a negative pressure drainage and irrigation machine 1. Fixed plates 12 are fixedly connected to both sides of the bottom of the negative pressure drainage and irrigation machine 1. Springs 13 are fixedly connected to the outside of the fixed plates 12. The ends of the springs 13 are fixedly connected to a push plate 14. Slide blocks 15 are fixedly connected to the front and rear sides of the top of the push plate 14. Slide grooves 17 are provided on the left and right sides of the bottom wall of the negative pressure drainage and irrigation machine 1. The slide blocks 15 are respectively slidably connected to the corresponding slide grooves 17. Among them, a fillet can be provided below the push plate 14.

[0025] Through holes 10 are also provided on the push plate 14. Specifically, two through holes 10 can be provided on the front and rear sides of the middle and lower parts thereof. Bolt I 11 is threadedly connected to the inside of the through hole 10. The setting of the bolt I 11 can fix the two push plates 14.

[0026] On the outside of the negative pressure drainage and irrigation machine 1, an adjusting mechanism 2 is also installed; at the top of the negative pressure drainage and irrigation machine 1, a drainage pipe 7 is connected, and a valve 6 is installed on the outside of the drainage pipe 7; at the end of the drainage pipe 7, a suction head 9 is connected; an exhaust pipe 8 is also connected to the negative pressure drainage and irrigation machine 1, specifically, it can be set on both its front and back sides, and the air inhaled by the suction head 9 can be discharged through the exhaust pipe 8.

[0027] During use, place the above-mentioned negative pressure drainage and irrigation device for ophthalmic care on the bed frame of the hospital bed. This operation is simple and does not require additional tool assistance; next, while loosening the device, the rounded push plate 14 collides with the bed frame; this design enables the push plate 14 to smoothly contact the bed frame, avoiding friction and obstruction caused by angle problems; after the collision, the downward pressure of the device causes the spring 13 to drive the push plate 14 to move; this design enables the push plate 14 to automatically adjust its position according to the pressure of the device, improving the flexibility and adaptability of the device; at the same time, the movement of the push plate 14 drives the slider 15 to slide within the chute 17; this design plans the movement trajectory of the push plate 14, making the device more stable and reliable during the fixing process; next, through the push of the spring 13, the push plate 14 squeezes the bed frame; this squeezing force enables the push plate 14 to firmly clamp the bed frame, ensuring that the device will not shift during the treatment process;

[0028] At the same time, take the bolt 11 and insert it into the through hole 10, and pull the distance between the push plates 14 through the bolt 11, further enhancing the fixing effect of the push plate 14 on the bed frame; finally, install the device at the head of the hospital bed; this installation method avoids the obstruction of the device to the doctor's treatment work caused by the way of placing it on the ground, bringing convenience to the doctor's treatment work; in short, this negative pressure drainage and irrigation device fully considers the actual needs of doctors in the design and use process, effectively solves the problem of device fixation, and improves the treatment efficiency.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in, the adjusting mechanism 2 includes a fixed rod 201, the fixed rod 201 is arranged on the outside of the negative pressure drainage and irrigation machine 1, the top of the fixed rod 201 is equidistantly and fixedly connected with a plurality of connecting rods 202, the top ends of the connecting rods 202 are fixedly connected with a semi-hollow shell 207, a threaded hole 206 is opened on the outer wall of the semi-hollow shell 207, a rotary bolt 205 is threadedly connected to the inside of the threaded hole 206, a ball 204 is rotatably connected to the inside of the semi-hollow shell 207, and a fixing ring 203 is fixedly connected to the outside of the ball 204.

[0030] Furthermore, an adjusting knob 16 is installed on the outside of the connecting rod 202; the height of the connecting rod 202 can be adjusted through the adjusting knob 16 to adapt to the head shapes and heights of different patients.

[0031] During use, insert the suction head 9 on the drainage tube 7 into the corresponding fixing ring 203. This step is to ensure that the drainage tube 7 and the suction head 9 can be stably maintained in the correct position during the treatment process. During the insertion process, pay attention to keeping the drainage tube 7 smooth to avoid twisting or folding to ensure the normal operation of the negative pressure system. Next, rotate the ball 204 through the fixing ring 203 to adjust the angle of the suction head 9. This step is very crucial because the angle of the suction head 9 directly affects the extraction effect of the intraocular fluid during the treatment process. When adjusting the angle of the suction head 9, ensure that the distance between the suction head 9 and the patient's eye is appropriate, so as to ensure the effect during fluid extraction and avoid discomfort to the patient.

[0032] After determining that the angle of the suction head 9 is appropriate, rotate the rotating bolt 205. By rotating the bolt 205 to generate rotation in the threaded hole 206, the rotating bolt 205 squeezes the ball 204. The purpose of this step is to fix the angle of the ball 204 and thus fix the position of the suction head 9. This can ensure that during the treatment process, the suction head 9 can be stably maintained in the predetermined position, improving the accuracy of the treatment.

[0033] After completing the above steps, turn on the negative pressure drainage and irrigation machine 1 to generate negative pressure, and at the same time open the valve 6. Under the action of negative pressure, the suction head 9 extracts the fluid in the patient's eye. This operation method greatly reduces the doctor's workload, and the doctor does not need to hold the suction head 9 all the time for the treatment process. At the same time, through the cooperation between multiple rotating bolts 205, the accuracy of the fixed position is ensured, making the treatment process safer and more effective. By adjusting the knob 16, the height of the connecting rod 202 can be adjusted to adapt to the head shapes and heights of different patients.

[0034] Refer to Figure 1 As shown in the figure, an external ring 5 is installed on the outside of the negative pressure drainage and irrigation machine 1. A vertical plate 3 is fixedly connected to the top of the external ring 5. A second bolt 4 is threadedly connected to the left side of the vertical plate 3, and the vertical plate 3 is threadedly connected to the negative pressure drainage and irrigation machine 1 through the second bolt 4.

[0035] Specifically, through the cooperation between the external ring 5, the vertical plate 3 and the second bolt 4, the overall stability of the device is increased.

[0036] The working principle of the above-mentioned negative pressure drainage and irrigation device for ophthalmic care is as follows:

[0037] When fixing the negative pressure drainage and irrigation device for ophthalmic care, place the device on the bed frame of the hospital bed. While loosening the device, the rounded push plate 14 collides with the bed frame. The force of the device pressing down drives the spring 13 to drive the push plate 14 to move by extrusion. The movement of the push plate 14 drives the slider 15 to slide in the chute 17, planning the movement trajectory of the push plate 14. Thus, the push plate 14 is pushed by the spring 13 to press against the bed frame. At the same time, take the first bolt 11 and insert it into the through hole 10, and pull the distance between the push plates 14 through the first bolt 11, so that the push plate 14 clamps and fixes the bed frame, and then installs the device at the head of the hospital bed, avoiding the way of placing on the ground from causing obstacles to the doctor's treatment work and bringing convenience to the doctor's treatment work;

[0038] When using the negative pressure drainage and irrigation device for ophthalmic care, insert the drainage tube 7 and the suction head 9 into the corresponding fixing ring 203. Rotate the rolling ball 204 through the fixing ring 203 to adjust the angle of the suction head 9. After the angle is appropriate, rotate the rotating bolt 205. The rotating bolt 205 rotates in the threaded hole 206, so that the rotating bolt 205 presses on the rolling ball 204. Through the cooperation between multiple rotating bolts 205, the angle of the rolling ball 204 is fixed, and then the position of the suction head 9 is fixed. Turn on the negative pressure drainage and irrigation machine 1 to generate negative pressure and turn on the valve 6 at the same time, so as to draw out the accumulated fluid in the patient's eye together with the suction head 9. There is no need for the doctor to hold the suction head 9 all the time during the treatment process, and at the same time, the accuracy of the fixed position is guaranteed, which can meet the usage requirements.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
