Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a prone position ventilation head pressure reducer. Background Art
[0002] Prone ventilation is widely used in the ICU as a feasible and effective means of lung protective ventilation strategy. It has been confirmed in the literature that prone ventilation can improve the oxygenation of patients with severe ARDS by 70%-80%. When the oxygenation improvement is limited after 12-24 hours of mechanical ventilation and PaO2 / FiO2 is less than 0 mmHg, prone ventilation treatment can be considered. Its main principles are: effectively improve the ventilation-blood flow ratio, expand the dorsal collapsed alveoli, facilitate the postural drainage of secretions in the trachea and bronchi under the action of gravity, change the movement mode and position of the diaphragm, increase the functional residual capacity and reduce the pressure of the heart on the lungs.
[0003] The protective kits in the prior art lack reliable and practical protective devices, which greatly increases the incidence of adverse events and currently have the following problems:
[0004] 1. When the patient is in the prone position for ventilation, the forehead, zygomatic arch, and mandibular prominence of the patient's face become the pressure-supported areas. The skin in these areas is thinner than other parts of the body, has less friction resistance, and is at a low level, which makes it easy for water to accumulate. In addition, the tissue is tender and there is little subcutaneous fat, which makes it very easy for the skin to be damaged due to long-term pressure.
[0005] 2. Due to the obstruction of venous return during prone ventilation, patients are prone to complications such as pressure sores, edema on the face, eye edema, inflammatory reaction, optic nerve damage, etc. Once facial complications occur in patients undergoing prone ventilation, it not only increases the patient's pain, but also increases the patient's medical expenses.
[0006] 3. Poor plasticity and easy to injure the skin: Traditional wedge-shaped pads (sponge) and pillows do not fit the body contour, or cannot support the torso, or easily injure the skin.
[0007] 4. High risk of tube dislocation: compression, twisting, displacement and dislocation of artificial airways, arteriovenous tubes and various drainage tubes.
[0008] Therefore, a prone position ventilation head pressure reducer is proposed to solve the current shortcomings. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.
[0034] In conjunction with the accompanying drawings, a prone position ventilation head pressure reducer includes a head placement frame 1, a support airbag 2 and a pillow 3;
[0035] The head placement frame 1 supports the support airbag 2. The structure of the head placement frame 1 is set according to actual conditions. In this embodiment, the head placement frame 1 is a rectangular structure.
[0036] The four bottom corners of the head placement frame 1 are provided with adjustable feet 4. Specifically, the adjustable feet 4 include a support rod 12 connected to the head placement frame 1 and a support seat 13 threadedly connected to the lower end of the support rod 12. By rotating the support seat 13, the height of the head placement frame 1 can be adjusted.

[0043] In actual use, the controller can realize independent control of the control switch 14 of the corresponding support airbag 2, thereby realizing the control of the inflation and deflation of the support airbag 2 at different positions.
[0044] The support airbag 2 located in the middle position is coaxially penetrated by a pipeline channel 6 and has a through hole 7 connected to the pipeline channel 6 on the upper side. The arrangement of the pipeline channel 6 and the through hole 7 can facilitate the operation of prone ventilation treatment, and also facilitate the installation of artificial airways, arteriovenous conduits and various drainage tubes, thereby avoiding compression and distortion of the pipelines.
[0045] A clamping ring 8 is provided at both sides of the pillow 3 corresponding to the pipeline channel 6, and a pipeline fixer 9 is clamped in the clamping ring 8;
[0046] In actual use, the pipe holder 9 is fixed on the pipe by the cooperation with the pipe, and the pipe holder 9 is fixed on the pipe by the clamping cooperation with the clamp ring 8 to prevent the pipe from falling out.
[0047] An arc-shaped card plate 10 is movably provided in the middle of the front side of the head placement frame 1, and a flexible pad 11 adapted to the support airbag 2 is provided on the arc-shaped card plate 10. Specifically, the arc-shaped card plate 10 is semicircular, and the arc-shaped card plate 10 is connected to the head placement frame 1 through a card slot.
