Description

Technical Field

[0001] This utility model belongs to the field of ophthalmic rehabilitation, specifically a prone device for postoperative ophthalmic surgery. Background Technology

[0002] In ophthalmological clinics, patients who have undergone procedures such as vitrectomy often need to maintain a prone position for an extended period to promote retinal reattachment. Currently, patients typically use a prone pillow for rest.

[0003] For example, Chinese patent with publication number "CN218515888U" discloses "a prone position pillow after vitrectomy, which can be adjusted by twisting on both sides without disassembly... two sets of screw rings are connected to a set of screw rings on the inner side of the two sets of screw rings, the outer wall of the adjusting screw is screwed to the inner wall of the screw ring, the top of the two sets of adjusting screws is connected to the middle of the bottom of a set of levers, the rear end of the pillow ring is connected to the front end of the prone pad, and the pillow ring is laid on the top of the head tray".

[0004] However, the adjustment methods described in the patent have certain shortcomings in actual use: If a patient feels discomfort with the height of the pillow ring after lying face down on the mat, they either have to get up and manually rotate the screws on both sides to adjust and then lie face down again to try to reposition the pillow ring. If they are still uncomfortable, they need to get up and repeat the operation. However, for patients who are unable to move easily or have weak physical strength after surgery, the repeated process of getting up and adjusting can easily lead to fatigue, and frequent changes in body position may increase eye pressure. Alternatively, they can maintain a prone position and directly rotate the screws on both sides with their face against the pillow ring. When adjusting in a prone position, both hands need to operate the screws on both sides simultaneously to ensure height balance. This requires a high degree of limb coordination, which not only makes it difficult to accurately control the adjustment range, but may also cause the pillow ring to tilt due to uneven force, affecting the user experience. Both of these adjustment methods are cumbersome to operate and lack adaptability, making it difficult to meet the needs of postoperative patients for convenient and comfortable adjustment.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a prone positioning device for postoperative ophthalmic surgery. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a prone positioning device after ophthalmic surgery.

Detailed Implementation

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0020] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a prone device for postoperative ophthalmic surgery, including a pillow 1 and a prone pad 2 disposed on one side of the pillow 1. The bottom of the pillow 1 is provided with an adjustment mechanism 3 for adjusting the height of the pillow 1.

[0021] refer to Figure 1 The inner side of the pad 2 is provided with a breast pad 7, and the outer side of the breast pad 7 is provided with multiple elastic bands 8, and the elastic bands 8 are sleeved on the outer side of the pad 2.

[0022] When resting in a prone position, the patient can lie face down on the prone mat 2 with their chest in contact with the chest pad 7. The chest pad 7 provides flexible support to the chest, reducing the pressure on the chest cavity when lying prone. At the same time, multiple elastic bands 8 can adjust the position of the chest pad 7 according to the patient's body shape, preventing the chest pad 7 from shifting and improving support stability. The patient's face naturally rests on the pillow pad 1, and the height of the pillow pad 1 can be flexibly adjusted through the adjustment mechanism 3 at the bottom of the pillow pad 1.

[0023] refer to Figure 2 The adjustment mechanism 3 includes a base 31 located at the lower end of the pillow pad 1. A telescopic member 32 is located on the upper part of the base 31. A support airbag 33 is located on the inner side of the telescopic member 32. An air guide pipe 34 and an exhaust pipe 35 are located on the outer side of the support airbag 33. An inflatable airbag 36 is connected to the end of the air guide pipe 34 away from the support airbag 33. A one-way valve 37 is installed on the air guide pipe 34.

[0024] refer to Figure 3and Figure 4 The telescopic component 32 includes two arc-shaped sleeves 321 symmetrically distributed on the upper part of the base 31. An arc-shaped ring 322 is slidably arranged inside the arc-shaped sleeve 321. The upper end of the arc-shaped ring 322 extends through the arc-shaped sleeve 321, and the upper ends of the two arc-shaped rings 322 are jointly provided with a support seat 323.

[0025] refer to Figure 3 and Figure 4 The support airbag 33 is located between the base 31 and the support seat 323, and the upper part of the support seat 323 is in contact with the bottom of the pillow 1.

[0026] When the patient's face is naturally resting on the pillow pad 1, if the height of the pillow pad 1 needs to be raised, the patient can squeeze the inflatable airbag 36. Under pressure, the gas is delivered through the air tube 34 and flows into the support airbag 33 through the one-way valve 37. As the support airbag 33 inflates, it generates an upward thrust on the support seat 323 above. At this time, the arc-shaped rings 322 connected to both ends of the support seat 323 slide upward along the inner wall of the arc-shaped sleeve 321, providing a stable guide for the support seat 323 to avoid tilting. As the support seat 323 rises, it drives the pillow pad 1 on top to rise synchronously. The patient can perceive the height change through real-time contact between the face and the pillow pad 1 until the head is adjusted to a comfortable position, and then stop squeezing the inflatable airbag 36. The patient does not need to get up and can adjust by squeezing the inflatable airbag 36 while maintaining a prone position, avoiding the tediousness of repeatedly getting up or making large movements. It is especially suitable for patients with limited mobility and weak physical strength after surgery, and lowers the operation threshold.

[0027] It should be noted that the telescopic component 32, including the arc-shaped sleeve 321, the arc-shaped ring 322, and the support base 323, can be made of high-strength plastic or lightweight alloy. These materials have both sufficient structural strength and good wear resistance, which can stably support the weight of the head and the pillow 1, and are lightweight, so as not to increase the overall burden of the device. At the same time, the surface can be smoothed to reduce the sliding friction resistance between the arc-shaped ring 322 and the arc-shaped sleeve 321, and ensure smooth lifting process.

[0028] refer to Figure 5 The exhaust pipe 35 is threaded with a connector 4 at one end away from the supporting airbag 33. A sealing plug 5 is provided at one end of the connector 4 inside the exhaust pipe 35, and an exhaust hole 6 is provided at the sealing plug 5 of the exhaust pipe 35.

[0029] When the patient's face is naturally resting on the pillow 1, if the height of the pillow 1 needs to be lowered, the patient's face must remain in contact with the pillow 1, and the weight of the head will continuously act on the support base 323. In this state, the patient can perceive the height change through the real-time contact between the head and the pillow 1. Then, the patient only needs to turn the connector 4 with one hand, which will drive the sealing plug 5 away from the vent 6 through the threaded transmission. At this time, the gas in the support airbag 33 can be discharged through the vent 6 on the vent pipe 35. Then, the volume of the support airbag 33 will decrease, and its pressure on the support base will decrease. As the upward support force of 323 gradually weakens, the pressure on the patient's head, the weight of the pillow 1 and the support seat 323 will form a downward resultant force. Under the action of this resultant force, the support seat 323 will push the arc ring 322 to slide downward along the inner wall of the arc sleeve 321. At the same time, the patient's head will feel the slight change in pressure, thereby judging whether the current height is appropriate. Once the height is appropriate, the connector 4 is turned in the opposite direction, and the sealing plug 5 moves with it to re-seal the vent hole 6, preventing the gas from continuing to escape, thus locking the current usage height of the pillow 1.

[0030] Furthermore, during the adjustment process, if the connector 4 is rotated slightly, the sealing plug 5 will partially disengage from the vent hole 6, and the gas will slowly escape, causing the cushion 1 to descend slowly. If the connector 4 is rotated significantly, the sealing plug 5 will completely move away from the vent hole 6, and the gas will escape rapidly, thus meeting the different adjustment speed requirements.

[0031] refer to Figure 2 and Figure 4 The base 31 has multiple vents 9, which are arranged in a circular array.

[0032] Among them, when the patient lies prone for a long time, the ventilation port 9 can prevent the base 31 from becoming stuffy due to the seal between it and the contact surface, thus improving the patient's comfort.

[0033] refer to Figure 1 The sleeping pad 2, pillow 1 and chest pad 7 are all made of soft and breathable material.

[0034] The soft and breathable material conforms naturally to the patient's body when lying on their back, avoiding local pressure and reducing the sticky discomfort caused by sweat accumulation, allowing the patient to maintain a comfortable experience when changing positions.

[0035] Working principle: When the patient lies prone, they can lie on the prone mat 2 with their chest in contact with the chest pad 7, and their face naturally resting on the pillow pad 1. The patient can then voluntarily squeeze the inflatable air bladder 36. Under pressure, gas flows unidirectionally into the support air bladder 33 through the air tube 34 and the one-way valve 37. After the support air bladder 33 inflates, it generates an upward thrust on the support seat 323 above, causing the arc-shaped rings 322 connected to both ends of the support seat 323 to slide upward along the inner wall of the symmetrically distributed arc-shaped sleeves 321 on the upper part of the base 31. This provides a stable guide for the support seat 323 to avoid tilting. As the support seat 323 rises, it also drives the pillow pad 1 on top to rise synchronously. The patient's face moves in real time against the pillow pad 1. The system senses changes in height and stops inflating the airbag 36 once a comfortable position is reached. To lower the height of the pillow 1, the patient simply twists the connector 4 to move the piston away from the vent 6. At this point, the gas inside the support airbag 33 can be released through the vent 6 on the vent pipe 35. Once the height is suitable, the connector 4 is twisted in the opposite direction, and the sealing plug 5 moves to re-seal the vent 6, preventing further gas release and locking the current height of the pillow 1. The patient does not need to get up during the entire adjustment process; they can complete the adjustment while remaining in a prone position. This avoids the hassle of repeatedly getting up or making large movements, making it especially suitable for patients with limited mobility or weak physical strength after surgery, thus lowering the operational threshold.
