Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a head posture adjuster after vitrectomy. Background Art

[0002] Vitrectomy is a surgery that removes cloudy vitreous or vitreoretinal traction, restores transparent refractive media and promotes retinal reattachment, treats vitreoretinal diseases, and restores the patient's visual function. During vitrectomy, silicone oil or inert gas is injected into the eye in order to use silicone oil and gas to fill the eye and press the retina to reattach. However, the retina of the human eye is located in the posterior segment of the eye, and the density of oil or gas is less than that of intraocular fluid. Therefore, after vitrectomy, the patient needs to keep the head parallel to the ground and the face facing down for a certain period of time to achieve the effect of pressing the retina. Therefore, medical staff usually recommend that patients lie in bed in a prone position for a few days to recuperate until they are fully recovered.

[0003] At present, this rehabilitation state of lying prone on the bed and maintaining the same posture for a long time is not acceptable to most people. Most patients have the need to get up and move around frequently. Therefore, in order to satisfy the needs of patients to get up and move around while keeping their heads parallel to the ground and their faces facing downward, the prior art adopts a structure of arranging a face support frame on a movable bracket to achieve the goal that the patient's face can be clipped into the face support frame when standing, so that the patient's face can remain in a downward posture when standing, thereby ensuring the effect of pressing the retina.

[0004] At present, the auxiliary support frame can only be used by the patient to control the movement of the head to achieve the head posture required for rehabilitation after the patient has completed standing. Therefore, it is very easy for the patient to cause retinal detachment due to improper movement when getting up to adjust the posture. In addition, the auxiliary support frame is always in contact with the ground during movement, and it is easy to shake when encountering obstacles, causing secondary damage to the patient's face and surgical site. At the same time, the auxiliary support frame cannot be worn by the patient all the time, nor can it be automatically adjusted to adapt to the patient, and it cannot actively control the patient's head to move to the standard posture required for postoperative rehabilitation. Therefore, it is very inconvenient to use. In addition, the patient maintains the face-down posture for a long time without a matching and suitable medication disinfection and cleaning device, which makes the subsequent medication and maintenance of the patient's eyes extremely difficult. Summary of the invention

[0005] In view of this, the purpose of the present invention is to propose a head posture adjuster after vitrectomy to solve the problem that there is no adjuster in the prior art that can be worn comfortably all the time when standing up and walking or lying prone, and can actively adjust the patient's head position according to the patient's posture, while also having a structure that is adaptable to such special body posture for applying and changing medicines, resulting in the existing equipment being unable to be worn all the time to adjust and protect the patient, and unable to ensure that the patient can safely switch between standing and lying positions. The use of the existing equipment is very likely to cause retinal detachment and secondary damage to the surgical site, and the problem that it is inconvenient to apply and change medicines makes the eyes prone to secondary infection due to poor dressing effects.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0031] like Figure 1-6, an embodiment of the present invention is: a head posture adjuster after vitrectomy, including a ring-shaped head mask 1, a shoulder fixing frame 3 is rotatably connected to the lower end of the ring-shaped head mask through a rotating mechanism 2, the rotating mechanism includes a fixed rotating shaft 4 and a rotating shell 5 rotatably arranged outside the fixed rotating shaft, the fixed rotating shaft is fixed at the middle position of the shoulder fixing frame, the lower end of the ring-shaped head mask is fixedly connected to the rotating shell, so that the ring-shaped head mask can rotate around the shoulder fixing frame following the rotation of the rotating shell, an elastic fixing belt 6 is fixedly arranged on the front side surface of the shoulder fixing frame, the movable end surface of the elastic fixing belt is arranged as a Velcro hook surface, and a Velcro fur surface adapted to the Velcro hook surface is fixedly arranged on the rear side surface of the shoulder fixing frame.

[0032] An inflator 8 is fixedly installed on the rear side of the shoulder fixing frame through a fixed support platform 7. The inflator includes an inflation motor 9 for inhaling and deflation, a rechargeable battery 10, a signal receiver 11 and a control center 12. The same horizontal sensor 13 is fixedly installed on the rear side of the ring head mask and the shoulder fixing frame respectively. The signal receiver is directly connected to the horizontal sensor through a line for receiving the position signal sensed by the horizontal sensor. The control center is connected to the inflation motor, the rechargeable battery and the signal receiver through lines for receiving signals and controlling the inflation motor. An inflation push tube 14 is arranged between the inflator and the ring head mask. The inflation push tube consists of an inflation pipe 15 and a push plate 16 for pushing the ring head mask. The push plate is fixedly installed on the rear side of the ring head mask.

[0033] An eye patch changing device 17 is pasted and fixed at the eye part of the ring-head mask. The left and right sides of the eye patch changing device are pasted and fixed to the front of the ring-head mask by Velcro 18. The eye patch changing device includes an elastic support belt 19, on which two flexible eye pads 20 are fixedly arranged. A disposable dressing sheet 21 is arranged on the inner surface of the flexible eye pads. A liquid medicine delivery pipe 22 is connected between the two flexible eye pads. A liquid medicine delivery device 23 is fixedly arranged on the rear side of the ring-head mask, and the liquid medicine delivery pipe and the liquid medicine delivery device are connected.

[0034] When the present embodiment is implemented, the patient's head is first placed inside the ring-shaped mask when the patient is lying prone. After the ring-shaped mask is put on, the shoulder fixing frame is adjusted by rotation to align it with the patient's shoulder and the patient's shoulder is put into the shoulder fixing frame. Then, the movable end of the elastic fixing belt is passed through the patient's armpit, and the Velcro hook surface on the movable end is fitted with the Velcro fur surface on the rear side of the shoulder fixing frame for fixing. Then, the inflator and the level sensor are started. When the patient needs to get up from the prone state, the level sensor will sense due to his own movement. The level sensor sends the sensed information to the signal receiver through a signal. The signal receiver inputs the received signal to the control center. The control center processes the obtained level signal according to the setting, and then controls the inflation motor to inflate the inflation push tube. The inflation push tube will push the push plate due to inflation, so that the push plate drives the ring-shaped mask to rotate. The ring-shaped mask will eventually be pushed to the target position, thereby continuing to ensure that the patient's posture can achieve top pressure on the retina, thereby ensuring that the patient can maintain the standard head posture required for rehabilitation during the posture conversion process.

[0035] If the patient needs to recover from a standing position to a prone position, the sensor also senses the change in horizontal state and provides a signal to enable the control center to control the inflation motor to extract the gas in the inflation pipe. The driving force of the gas slowly disappears, allowing the ring-shaped mask to slowly rotate back to the prone position, so that the patient can continue to rest in the prone position.

[0036] When the patient needs to change the medicine, he only needs to aim the eye patch changer around the eye and gently stick it on, then start the medicine delivery device. The medicine will be delivered to the flexible eye pad through the medicine delivery tube, and then the medicine will seep into the disposable dressing sheet, so that the eye is evenly contacted with the medicine without worrying about dripping. When the medicine is applied, he only needs to replace the disposable dressing sheet, and then use the medicine delivery tube to deliver disinfectant liquid to complete the disinfection.

[0037] This embodiment provides a wearable head posture adjustment structure with both horizontal sensing and active adjustment functions, which is beneficial to achieving the synchronous sensing of posture changes when the patient switches from lying to standing during the rehabilitation process after wave cutting surgery, and synchronously making active adjustments to the patient's head posture, thereby ensuring that the patient can continuously and stably maintain the head state that presses the retina, ensuring that the patient can safely switch between lying and standing states, and avoiding secondary injuries during the rehabilitation process. By providing a simple and easy-to-wear comfortable wearing structure, it is beneficial to achieve that the device can be worn all the time, avoiding the complicated operation of frequent removal and replacement, and also avoiding damage to the patient's surgical site during frequent wearing. In addition, through the adaptive replacement of medicine eye patches, it is convenient for patients to quickly change medicines and avoid secondary infections.

[0038] In this embodiment, the inflatable pipe is an airtight pipe with telescopic function, and the connection between the inflatable pipe and the push plate is sealed. The setting of the airtight pipe with telescopic function and the sealing installation are conducive to realizing that when the pipeline is supplied or deflated, the gas in the pipe can continue to expand and increase the pressure or quickly reduce the pressure, thereby driving the telescopic push and pull operation, and providing sufficient push and pull force to realize the effective push and pull of the ring head mask.

[0039] In this embodiment, the ring-shaped head mask is composed of an elastic metal frame and a detachable soft cloth cover wrapped around the outside of the elastic metal frame. An elastic sponge pad is fixedly arranged on the rear side of the inner cavity of the ring-shaped head mask. The shoulder fixing frame is composed of an arched metal frame and a flexible protective pad wrapped around the outside of the arched metal frame. The design is carried out in the form of a hard metal inner frame with a soft outer protective cover, which is beneficial for patients to meet the required rigidity when wearing it, and can greatly improve the comfort, thereby avoiding possible damage to the patient caused by the device itself.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
