Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an anti-pressure ulcer auxiliary ventilator capable of adapting to changes in body position. Background Art
[0002] A ventilator is an effective means of artificially replacing spontaneous ventilation. It is also a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives. Especially for patients with chronic respiratory diseases receiving treatment in respiratory medicine departments, who need to wear a ventilator for a long time during their hospital stay, the ease and safety of ventilator use are extremely important.
[0003] At present, in the prior art, when patients in the respiratory department who wear ventilators for a long time use the ventilators, they often use a sliding bracket to assemble the ventilator on the bracket and then move it to the patient's bedside, and then use a telescopic breathing hose to connect the breathing mask and the ventilator.
[0004] At present, the existing technology uses a breathing hose to connect the breathing mask and the ventilator. Due to the softness of the breathing hose, it is easy for the patient to turn around and move his body to press on the breathing hose or cause the breathing hose to fold and become blocked. In addition, when the sleeping position changes, the hand moves and presses on the breathing hose, causing the breathing hose to be blocked, thereby preventing the ventilator from supplying air normally, and even causing the patient's breathing to be obstructed and suffocated. Secondly, wearing the breathing mask tightly for a long time can easily cause the patient's face to be under pressure and uncomfortable for a long time. Summary of the Invention
[0005] In view of this, the purpose of the present invention is to propose an anti-pressure ulcer auxiliary ventilator that adapts to changes in body position. By setting up an auxiliary ventilator that is equipped with a breathing mask tracking and following structure, a breathing trachea retraction structure and a breathing mask timed release structure, the problem in the prior art is that there is a lack of an auxiliary ventilator that can adjust the position of the breathing trachea according to the patient's body position to prevent the pipeline from being excessively pulled or squeezed, and a breathing mask that can be released timed. As a result, the breathing pipeline of the ventilator is inflexible when used and is easily bent or compressed, resulting in blockage, and even causing the patient to be unable to breathe normally and suffocate, and the mask is worn for too long, causing pressure damage to the face and causing severe discomfort to the patient.
[0006] The present invention is achieved through the following technical solutions:
[0007] A pressure sore-proof auxiliary ventilator that adapts to changes in body position includes a ventilator main body, a body position tracking slide rail fixedly provided on the upper end of the ventilator main body, a breathing tube retractor slidably provided on the lower end of the body position tracking slide rail, the breathing tube retractor is equipped with an anti-bending trachea, one end of the anti-bending trachea is connected to the ventilator main body, and the other end of the anti-bending trachea is connected to a positioning breathing mask, an automatic release fixing belt is fixedly provided on the outside of the positioning breathing mask, and a central controller is fixedly provided on the upper end of the ventilator main body, and the central controller is respectively connected to the body position tracking slide rail, the breathing tube retractor, the positioning breathing mask and the automatic release fixing belt through wireless signals.
[0008] Furthermore, the body position tracking slide rail includes an electric linear slide rail, an electric sliding base is slidingly provided at the lower end of the electric linear slide rail, the breathing tube retractor is fixedly provided on the top of the electric sliding base, the breathing tube retractor includes a retractor shell, a group of electric rollers are fixedly provided inside the retractor shell, and the surface of the electric roller is set to a toothed rough surface.

[0010] Furthermore, the inner layer of the anti-bending air pipe is a plastic tube layer, the middle layer of the anti-bending air pipe is a spring steel sheet metal layer, and the outer layer of the anti-bending air pipe is a rubber protective outer layer.
[0011] Furthermore, the positioning breathing mask includes a fixed mask body and a face gasket, a pressure sensing membrane is fixedly provided on the inner side of the face of the face gasket, and the automatic release fixing belt is fixedly provided on the left and right sides of the fixed mask body.
[0012] Furthermore, the automatic loosening and fixing belt includes an electric rolling retractor fixedly arranged on the fixed cover body, and the electric rolling retractors on the left and right sides are connected by a flexible fixing belt.
[0013] Furthermore, pressure sensors are provided at the contact points between the two sides of the breathing tube retractor and the anti-bending trachea.
[0014] Furthermore, a manual release switch is provided on the fixed cover.
[0015] The beneficial effects of the present invention are:
[0016] The present invention provides an auxiliary ventilator with a breathing mask tracking and following structure, a breathing trachea retracting and releasing structure and a breathing mask timed release structure. It uses a position signal transmitter to track the mask position, and combines a body position tracking slide rail and a breathing tube retracting and releasing device to adjust the anti-bending trachea, thereby facilitating automatic adjustment of the trachea position and extension length according to the patient's facial movement to avoid the phenomenon of folding or excessive stretching of the trachea, thereby ensuring that the trachea is continuously unobstructed and can be used normally.

These terms are intended solely to facilitate the description of the present invention and simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and the like are used solely for distinction and should not be construed as indicating or implying relative importance.
[0032] Furthermore, the term "identical" and similar terms do not necessarily require that the components be absolutely identical; slight variations are permitted. The term "perpendicular" simply refers to the positional relationship between components being more perpendicular than "parallel," not that the structure must be perfectly vertical; rather, it can be slightly tilted.
[0033] like Figure 1-9 As shown, an embodiment of the present invention is: an anti-pressure sore auxiliary ventilator that adapts to changes in body position, including a ventilator body 1, a body position tracking slide 2 is fixedly provided at the upper end of the ventilator body, the body position tracking slide includes an electric linear slide 3, an electric sliding base 4 is slidingly provided at the lower end of the electric linear slide, a breathing tube retractor 5 is fixedly provided on the top of the electric sliding base, the breathing tube retractor includes a retractor shell 6, a group of electric rollers 7 are fixedly provided inside the retractor shell, the surface of the electric roller is provided with a toothed rough surface 8, and catheter guide ports 9 are provided at both ends of the retractor shell.
[0034] An anti-bending trachea 10 is assembled in the breathing tube retractor. The inner layer of the anti-bending trachea is a plastic tube layer 11, the middle layer of the anti-bending trachea is a spring steel sheet metal layer 12, and the outer layer of the anti-bending trachea is a rubber protective outer layer 13. One end of the anti-bending trachea is connected to the main body of the respirator, and the other end of the anti-bending trachea is connected to a positioning breathing mask 14. The positioning breathing mask includes a fixed mask body 15 and a veneer gasket 16. A pressure sensing membrane 17 is fixedly provided on the inner side of the veneer gasket. An automatic releasing fixing belt 18 is fixedly provided on the outer side of the positioning breathing mask. The automatic releasing fixing belt is fixedly provided on the left and right sides of the fixed mask body. The automatic releasing fixing belt includes an electric roller retractor 19 fixedly provided on the fixed mask body. The electric roller retractors on the left and right sides are connected by a flexible fixing belt 20.
[0035] A central controller 21 is fixedly mounted on the upper end of the ventilator body. It is wirelessly connected to the position-tracking slide rail, the breathing tube retractor, the positioning breathing mask, and the automatic release and tightening strap. A position signal transmitter 22 is fixed to the position-fixing breathing mask's connection pipe, and a position signal receiver is fixed inside the central controller. Pressure sensors 23 are installed on both sides of the breathing tube retractor where they contact the anti-bend airway. These pressure sensors are wirelessly connected to the central controller.
[0036] When implementing this embodiment, the automatic loosening and fixing belt on the positioning breathing mask is first loosened, and then the positioning breathing mask is worn on the patient's face. Then, the automatic loosening and fixing belt is controlled to be tightened so that the positioning breathing mask can completely fit the patient's face.
[0037] After the wearing is completed, the central controller begins to receive signal data transmitted from the entire device in real time. When the patient is sleeping, instructions are set in the central controller in advance, and the position signal transmitter on the breathing mask transmits the patient's real-time position information. Then, when the patient's body position deflects and the face moves, the position signal changes. Then, the central controller receives the data of the position signal change and begins to control the body position tracking slide rail, so that the electric sliding base drives the breathing tube retractor to move accordingly with the change in the position of the breathing mask, so that the breathing tube retractor drives the anti-bending trachea close to the breathing mask position. At the same time, by sensing the pressure data transmitted back by the pressure sensor, if the pressure of the pressure sensor near the breathing mask end increases first, it proves that the anti-bending trachea is being pulled. At this time, in order to allow the anti-bending trachea to be pulled out smoothly to avoid generating excessive pulling force to pull the breathing mask off, the central controller controls the electric roller to rotate in the direction of outputting the anti-bending trachea, thereby releasing a longer anti-bending trachea to adapt to the pulling of the anti-bending trachea caused by the patient turning over and turning. When the electric sliding base drives the breathing tube retractor close to the breathing mask after the body position changes, the electric rolling wheel is activated to rotate it in the direction of retracting the anti-bending trachea, thereby retracting the anti-bending trachea to an appropriate length to avoid the excessively long anti-bending trachea from shaking in the outside world and causing discomfort to the patient.
[0038] During the wearing process of the respiratory mask, the release time and release pressure are set on the central controller, and the pressure sensing membrane of the respiratory mask is positioned to sense the pressure of the face in real time. When the fixed release time is reached, the central controller controls the electric roller retractor to extend the flexible fixing belt to reduce the tension of the flexible fixing belt. When the sensed face pressure value reaches the target set value range, the release stops. After a certain period of release, the central controller controls the electric roller retractor again to retract and tighten the automatic release fixing belt, so that the pressure sensed on the pressure sensing membrane returns to the set firm wearing pressure value range, thus completing a complete release and re-tightening. In this way, timed release is achieved to avoid pressure sores caused by continuous pressure.
[0039] This embodiment provides an auxiliary ventilator with a breathing mask tracking and following structure, a breathing trachea retracting and releasing structure, and a breathing mask timed release structure. It uses a position signal transmitter to track the mask position, and combines a body position tracking slide rail and a breathing tube retractor to adjust the anti-bending trachea, which is conducive to automatically adjusting the trachea position and extension length according to the patient's facial movement to avoid the phenomenon of folding or excessive stretching of the trachea, thereby ensuring that the trachea is continuously unobstructed and can be used normally. The pressure sensing membrane and the electrically controlled automatic release and release of the fixing belt are conducive to timely release of the breathing mask's tight fit, thereby avoiding the problem of the breathing mask squeezing the face for a long time causing discomfort or even pressure sores in the patient, thereby improving the comfort of using the ventilator.
[0040] In this embodiment, a manual release switch is provided on the fixed mask body, which is helpful for the patient to control the manual switch to release the breathing mask when he feels uncomfortable.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. 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 solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
