Description

Technical Field

[0001] The invention relates to the field of operating chairs and treatment chairs specially suitable for patients, and in particular to an auxiliary device for eye treatment. Background Art

[0002] Tear duct irrigation is a common ophthalmic diagnostic and treatment technique used to evaluate and treat the patency of the tear duct system. This procedure involves injecting saline or other irrigation fluids into the lacrimal puncta to remove foreign matter or secretions from the tear duct and to assess the presence and location of obstruction in the tear duct.

[0003] During tear duct irrigation, in order to ensure that the irrigation needle can be accurately inserted into the lacrimal puncta and the irrigation solution can be smoothly injected, the patient's head is usually required to remain tilted upward. The current operation method is to let the patient sit on a stool with his head against the wall to keep it stable. At the same time, medical staff also need to fix the patient's head with their hands to prevent the head from shaking involuntarily due to the patient's nervousness or resistance. This not only increases the complexity and difficulty of the operation, but also poses certain safety risks.

[0004] In order to solve the above problems, the prior art discloses a treatment chair specially designed for tear duct flushing. This special treatment chair is equipped with a head support device, which can effectively fix the patient's head without the need for medical staff to fix it manually, significantly improving the safety and convenience of operation. However, in actual clinical applications, this technology still has the following shortcomings: clinically, it is often necessary to perform tear duct flushing for patients in wheelchairs. The existing special treatment chairs for tear duct flushing require patients to transfer to the treatment chair for operation, which is a significant challenge for wheelchair patients. Safely and conveniently transferring patients from wheelchairs to treatment chairs is not only complicated to operate, but may also bring additional risks and inconveniences. From the above analysis, it can be seen that although the prior art has made progress in improving the safety and convenience of tear duct flushing operations, it still needs to be further optimized in adapting to the needs of wheelchair patients. Summary of the invention

[0005] The present invention is intended to provide an auxiliary device for eye treatment to solve the problem that the prior art is inconvenient for washing the tear ducts of wheelchair patients.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] An auxiliary device for eye treatment comprises a treatment chair, which comprises a chair back. A positioning hole is opened on the chair back in the thickness direction, and the positioning hole runs through the chair back. A head cover is rotatably arranged on the top of the chair back. The top and bottom ends of the head cover are slidably connected with positioning rods, and the positioning rods can be clamped in the positioning holes. An unlocking rod is slidably arranged in the positioning hole. A spring is sleeved on the unlocking rod, one end of the spring is fixed to the inner wall of the positioning hole, and the other end of the spring is fixed to the unlocking rod. When the spring is in a free state, a space for the positioning rod to be clamped is reserved between the front end of the unlocking rod and the hole opening of the positioning hole on the front side of the chair back. Push rods for pushing the positioning rod are connected to both ends of the unlocking rod. Two accommodating holes for inserting the push-pull armrests on the top of the wheelchair are opened on the back of the chair back, and a driving component for driving the unlocking rod to slide toward the front side of the treatment chair is arranged in the accommodating hole.

[0008] Preferably, as an improvement, the driving assembly includes a baffle plate slidably disposed in the accommodating hole, the baffle plate is connected to an L-shaped connecting rod, and the other end of the connecting rod is fixed to the unlocking rod.

[0009] Preferably, as an improvement, a rubber limiting ring is fixed on the inner wall of the positioning hole, the cross-section of the limiting ring is semicircular, the diameter of the free end of the positioning rod is smaller than the inner diameter of the limiting ring, and the diameter of the positioning rod is larger than the inner diameter of the limiting ring.

[0010] Preferably, as an improvement, the accommodating hole is a horizontally arranged strip hole, and the treatment chair is a treatment chair that can be raised and lowered.

[0011] Preferably, as an improvement, air bags are fixed on the left and right inner walls of the headgear.

[0012] Preferably, as an improvement, avoidance grooves for avoiding the patient's ears are provided on the left and right sides of the headgear.

[0013] Preferably, as an improvement, the treatment chair is a rotatable treatment chair.

[0014] Preferably, as an improvement, an illumination lamp is fixed on the armrest of the treatment chair.

[0015] Preferably, as an improvement, a storage tray is fixed on the armrests of the treatment chair.

[0016] Preferably, as an improvement, a decompression ball is fixed on the armrest of the treatment chair.

[0017] The principles and beneficial effects of this scheme are:

[0018] 1. This solution takes into special consideration the needs of healthy patients and wheelchair patients. Its core includes the directional fixation and automatic unlocking functions of the headgear. Specifically: when a healthy patient uses it, the concave surface of the headgear faces the front of the treatment chair, and the positioning rod at the bottom of the headgear is inserted into the positioning hole on the front of the chair back. At this time, the unlocking rod does not move, and the spring remains in a natural state and is not compressed. When a wheelchair patient uses it, the wheelchair and the treatment chair are placed back to back so that the push-pull armrest on the top of the wheelchair can be inserted into the receiving hole on the back of the treatment chair. When the push-pull armrest is inserted into the receiving hole, the unlocking rod is pushed toward the front of the treatment chair through the baffle and the connecting rod. The movement of the unlocking rod causes the spring to be compressed, and the positioning rod located in the positioning hole is squeezed out, thereby automatically unlocking the headgear. After unlocking, the headgear can be flipped backwards so that its concave surface faces the back of the treatment chair. The wheelchair patient can sit in the wheelchair with his head fixed in the headgear for tear duct flushing.

[0019] This solution is suitable for both healthy patients and wheelchair patients. For wheelchair patients, there is no need to transfer from the wheelchair to the treatment chair, which reduces the inconvenience and risk during the transfer process and improves the overall treatment experience. In addition, for wheelchair patients, they only need to insert the push-pull armrest into the receiving hole to automatically unlock the headgear for flipping, without the need for additional manual operation. Compared with the traditional solution of using positioning pins, positioning gears, screws and other structures to fix the headgear, this solution can complete the unlocking by inserting and removing the push-pull armrest on the wheelchair, which greatly simplifies the operation process and reduces the workload of medical staff.

[0020] In summary, through clever design, this solution achieves the compatibility of the tear duct irrigation treatment chair for healthy patients and wheelchair patients. The automatic unlocking function of the headgear not only simplifies the operation process, but also significantly improves safety and user experience.

[0021] 2. This solution provides a special receiving hole to accommodate the push-pull armrest of the wheelchair, so that the wheelchair and the treatment chair can be closely connected, thereby ensuring that the headgear can effectively support and fix the wheelchair patient's head after flipping. This design ensures the stability and comfort of the wheelchair patient's head during the tear duct flushing process.

[0022] 3. The diameter of the free end of the positioning rod is reduced so that the free end can be smoothly inserted into the limit ring. By applying appropriate pressure, the rubber limit ring is forced to undergo elastic deformation, so that the positioning rod can smoothly pass through the limit ring and enter the positioning hole. Once the positioning rod is fully inserted, the limit ring relies on its reset performance to engage between the positioning rod and the inner wall of the positioning hole, fixing the positioning rod in the positioning hole.

[0023] 4. The treatment chair can be raised and lowered. In actual use, the height of the treatment chair can be adjusted to align the receiving holes on it with the push-pull armrests on the wheelchair for easy insertion. It can be used for wheelchairs of various heights and sizes. At the same time, the use of strip-shaped receiving holes can be used for push-pull armrests with spacing within a certain range, expanding the scope of application.

[0024] 5. An airbag is set on the inner wall of the headgear to clamp the patient's head. On the one hand, it can be used by patients with different head circumferences, and on the other hand, it can ensure comfort compared to rigid clamping. Avoidance grooves are set on both sides of the headgear to avoid the patient's ears, avoiding discomfort caused by squeezing the ears, and also facilitating conversations with medical staff during treatment.

[0025] 7. The rotatable treatment chair is convenient for rotating the treatment chair to adjust to the desired position, and it is also convenient to place it back to back with a wheelchair. The lighting is set to facilitate medical staff to quickly and accurately find the tear duct flushing puncture point, reduce the difficulty of operation, and improve the efficiency of operation. The storage tray is used to place the items needed for tear duct flushing, and the decompression ball is used for patients to squeeze and pinch to relieve pressure during the flushing process.

[0032] The following is further described in detail through specific implementation methods:

[0033] The figure marks in the drawings of the specification include: treatment chair 1, chair back 11, support rod 2, connecting shaft 21, headgear 22, positioning rod 23, sponge pad 24, airbag 25, push-pull armrest 3, wheelchair 31, limiting ring 5, push rod 51, unlocking rod 52, spring 53, positioning hole 54, accommodating hole 6, connecting rod 61, baffle 62, decompression ball 7.

[0034] Embodiment 1:

[0035] like Figure 1 , Figure 3 and Figure 4 As shown, an auxiliary device for eye treatment includes a treatment chair 1, the treatment chair 1 includes a chair back 11, and a positioning hole 54 is opened on the chair back 11 along the thickness direction. The positioning hole 54 passes through the front and back of the chair back 11. Figure 4 The left side is the front of the chair back 11, and the right side is the back of the chair back 11. Support rods 2 are bolted to both sides of the top of the chair back 11, and a connecting shaft 21 is bolted between the two support rods 2. A head cover 22 is rotatably mounted on the connecting shaft 21. The head cover 22 is set in a helmet shape, and a sponge pad 24 is glued to the inner wall of the head cover 22. Air bags 25 are fixed on the left and right inner walls of the head cover 22 to accommodate patients with different head circumferences.

[0036] The top and bottom ends of the head cover 22 are slidably connected with an L-shaped positioning rod 23. The top and bottom ends of the head cover 22 are provided with sliding grooves (not shown in the figure) along the depth direction. The sliding grooves are dovetail grooves that pass through the bottom of the head cover 22. The top end of the positioning rod 23 is set to be dovetail-shaped and slidably connected in the sliding groove. The positioning rod 23 can be clamped in the positioning hole 54. Specifically, a rubber limiting ring 5 is glued and fixed on the inner wall of the opening of the positioning hole 54. The cross section of the limiting ring 5 is semicircular. The diameter of the free end of the positioning rod 23 is slightly smaller than the inner diameter of the limiting ring 5. The diameter of the rod of the positioning rod 23 is slightly larger than the inner diameter of the limiting ring 5, which is about 0.1-0.5mm. By applying a certain pressure, the positioning rod 23 forces the limiting ring 5 to undergo elastic deformation, so that it passes through the limiting ring 5 and is inserted into the positioning rod 23. After the positioning rod 23 is fully inserted, it is clamped between the positioning rod 23 and the inner wall of the positioning hole 54 through the limiting ring 5, so as to achieve an interference fit between the positioning rod 23 and the positioning hole 54, thereby fixing the positioning rod 23 in the positioning hole 54. When a certain external force is applied outward, the positioning rod 23 can be pulled out of the positioning hole 54. The principle is similar to the fixing method of the pen cap in the prior art.

[0037] The unlocking rod 52 is slidably connected in the positioning hole 54, and a spring 53 is sleeved on the unlocking rod 52. One end of the spring 53 is fixed to the inner wall of the positioning hole 54 by a screw or a pin, and the other end of the spring 53 is fixed to the unlocking rod 52 by a screw or a pin. When the spring 53 is in a free state, a space A is left between the front end of the unlocking rod 52 and the opening of the positioning hole 54 on the front of the chair back 11 for the positioning rod 23 to be inserted. The two ends of the unlocking rod 52 are processed into a push rod 51 with a diameter smaller than the inner diameter of the limit ring 5, which is used to push the positioning rod 23. Figure 5As shown, the back of the chair back 11 is provided with two receiving holes 6 for inserting the push-pull armrest 3 on the top of the wheelchair 31, and a driving assembly for driving the unlocking rod 52 to slide toward the front of the treatment chair 1 is arranged in the receiving hole 6, and the driving assembly includes a baffle 62 slidably connected in the receiving hole 6, the baffle 62 is arranged vertically, and the baffle 62 is screwed to an L-shaped connecting rod 61, and the other end of the connecting rod 61 is fixed to the unlocking rod 52 by a screw. An installation cavity is provided in the chair back 11, and the driving assembly, the unlocking rod 52, the spring 53 and other components are installed in the installation cavity.

[0038] A method of using an auxiliary device for eye treatment is:

[0039] When used by healthy patients (compared to wheelchair users, patients with healthy legs), Figure 2 As shown, the concave surface of the head cover 22 faces the front of the treatment chair 1, and the positioning rod 23 at the bottom end of the head cover 22 is stuck in the hole 54 located in the front of the treatment chair 1, so that the head cover 22. Since there is a gap between the front end of the unlocking rod 52 and the hole 54 located in the front of the treatment chair 1 in the natural state, the positioning rod 23 will not drive the unlocking rod 52 to move when it is inserted into the positioning hole 54 at this time, and the spring 53 still maintains a natural state and is not compressed. The patient sits on the treatment chair 1, and the head is clamped in the head cover 22 by the airbag 25, so that the patient's head maintains an upward posture, and the head is supported and fixed. The medical staff uses a syringe to inject the flushing fluid from the lacrimal puncta into the lacrimal duct to flush the lacrimal duct.

[0040] When a wheelchair patient uses Figure 1 As shown, the wheelchair 31 and the treatment chair 1 are placed back to back, and the push-pull armrest 3 (the armrest used to hold to push the wheelchair 31) on the top of the wheelchair 31 is inserted into the receiving hole 6 on the back of the treatment chair 1, so that the wheelchair 31 and the treatment chair 1 are as close as possible. When the push-pull armrest 3 is inserted into the receiving hole 6, the unlocking rod 52 can be driven to push toward the front of the treatment chair 1 through the baffle 62 and the connecting rod 61. The movement of the unlocking rod 52 causes the spring 53 to be compressed, and the positioning rod 23 located in the positioning hole 54 is squeezed out, so that the head cover 22 is automatically unlocked. At the same time, the movement of the release rod makes the opening of the positioning hole 54 on the back of the treatment chair 1 vacant, and the unlocked head cover 22 is turned over to the back of the treatment chair 1. At this time, the positioning rod 23 at the top of the head cover 22 is turned to the bottom, and can be inserted into the vacant opening of the positioning hole 54 on the back of the treatment chair 1 and clamped, so that the head cover 22 is fixed in a state with the concave surface at the back. The wheelchair patient can sit on the wheelchair 31 with the head supported and fixed by the headgear 22 to perform tear duct flushing. There is no need to transfer the wheelchair patient 31 from the wheelchair 31 to the treatment chair 1, which makes treatment convenient.

[0041] After the treatment of the patient in the wheelchair 31 is completed, the wheelchair 31 and the treatment chair 1 are separated, and the push-pull armrest 3 on the wheelchair 31 is pulled out of the receiving hole 6 on the back of the treatment chair 1. The unlocking rod 52 loses the squeezing effect of the push-pull armrest 3 and is pushed to the back of the treatment chair 1 under the action of the spring 53. At this time, the baffle 62 and the connecting rod 61 are also reset with the movement of the unlocking rod 52. The reset of the unlocking rod 52 pushes the positioning rod 23 inserted in the positioning hole 54 from the back of the treatment chair 1, realizing the automatic unlocking of the head cover 22 on the back of the treatment chair 1. At this time, the head cover 22 can be flipped to the front of the treatment chair 1 for subsequent use by healthy patients.

[0042] Embodiment 2:

[0043] The difference between this embodiment and embodiment 1 is that the accommodating hole 6 is a horizontally arranged strip hole, and the treatment chair 1 is a treatment chair 1 that can be raised and lowered. The lifting and lowering of the treatment chair 1 is achieved by using the existing technology, and the lifting and lowering are achieved by using a gas pressure rod or a gas spring or a gas damper. Specifically, when sitting on the treatment chair 1, the user gently lifts or presses the adjustment handle on the treatment chair 1 with his hand. At this time, the adjustment valve is opened, and the gas can flow freely. An upward force is applied (such as standing or using the strength of the legs) to push the piston rod up until the desired height is reached. The adjustment handle is released, and the adjustment valve is automatically closed. The gas is sealed in the cylinder again to fix the height of the chair. When lowering the height of the treatment chair 1, it is also necessary to lift or press the adjustment handle, open the adjustment valve, apply a downward force (such as sitting down), and the piston rod gradually descends until the desired height is reached. The adjustment handle is released, the adjustment valve is closed, and the current height is locked. The specific lifting structure is an existing technology and will not be described in detail here.

[0044] Embodiment 1 is mainly applicable to common wheelchairs 31 commonly seen in hospitals. The conventional dimensions of common wheelchairs 31 are approximately 104 cm long, 65 cm wide, and 51 cm high. The position of the receiving hole 6 in Embodiment 1 is mainly set according to the dimensions of the common wheelchair 31. However, this embodiment adopts a treatment chair 1 that can be raised and lowered. In actual use, the height of the treatment chair 1 can be adjusted to match the height of the push-pull armrest 3 on the wheelchair 31 to adapt to wheelchairs 31 of different heights and sizes. In addition, this embodiment adopts horizontally arranged strip holes as the receiving holes 6, which can adapt to push-pull armrests 3 of different spacings, thereby adapting to wheelchairs 31 of different sizes and specifications, thereby expanding the scope of application.

[0045] Embodiment 3:

[0046] The difference between this embodiment and embodiment 1 is that the treatment chair 1 is a treatment chair 1 that can rotate. The rotation here refers to the self-rotation of the part above the base of the treatment chair 1. In addition, the legs of the treatment chair 1 are equipped with universal wheels, and the universal wheels are universal wheels with brakes. The rotation of the treatment chair 1 is achieved through existing technologies, such as fixing a central column at the bottom of the base of the treatment chair 1 to connect the base and the pedestal, which serves as the central axis of rotation, and providing low-friction rotation support through a rotating bearing. This is existing technology and will not be described in detail here. The use of a rotating treatment chair 1 facilitates its rotation and placement on the back of the wheelchair 31. The universal wheels installed on the legs facilitate the movement of the treatment chair 1. Of course, the rotation of the entire treatment chair 1 can also be achieved through universal wheels.

[0047] Embodiment 4:

[0048] The difference between this embodiment and embodiment 1 is that an illumination lamp (not shown in the figure) is fixed on the armrest of the treatment chair 1, so as to facilitate medical staff to find the position of the lacrimal puncta quickly and accurately.

[0049] Embodiment 5:

[0050] The difference between this embodiment and embodiment 1 is that a storage tray (not shown in the figure) is fixed on the armrest of the treatment chair 1 for placing items required for lacrimal duct flushing for easy access.

[0051] Embodiment 6:

[0052] Combination Figure 6 As shown, the difference between this embodiment and embodiment 1 is that a decompression ball 7 is fixed on the armrest of the treatment chair 1, and the installation of the decompression ball 7 is achieved through a ball seat (not shown in the figure), and the ball seat is fixed to the armrest by bolts. The decompression ball 7 is used for the patient to squeeze during the treatment to relieve tension. The decompression ball 7 can be a rubber ball or a silicone ball.

[0053] Embodiment 7:

[0054] The difference between this embodiment and embodiment 1 is that the airbag 25 is connected to an air pump (not shown in the figure), and the airbag 25 is connected to an air connector, which can be connected to the air outlet of the air pump through a pipeline. This embodiment makes it convenient to adjust the inflation amount of the airbag 25 as needed.

[0055] Embodiment 8:

[0056] The difference between this embodiment and the first embodiment is that a neck pillow (not shown in the figure) is glued and fixed to the bottom and top ends of the head cover 22, and the positioning rod 23 is slidably connected to the neck pillow.

[0057] Embodiment 9:

[0058] The difference between this embodiment and the first embodiment is that the left and right sides of the headgear 22 are provided with avoidance grooves (not shown in the figure) for avoiding the patient's ears to avoid squeezing the patient's ears.

[0059] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
