Description

Technical Field

[0001] The present invention belongs to the field of facial support, and specifically relates to a head and face support device for prone ventilation of patients. Background Art

[0002] Acute respiratory distress syndrome (ARDS) is an acute and diffuse inflammatory lung injury and is one of the common critical respiratory diseases endangering human health. The mortality rate of critically ill ARDS patients in the intensive care unit is between 40% and 50%. Mechanical ventilation is a key medical measure for treating ARDS patients. A reasonable mechanical ventilation treatment strategy can significantly reduce the mortality rate, otherwise it will further exacerbate the deterioration of the condition. In recent years, with the deepening of the understanding of the pathophysiology of ARDS and the continuous development of clinical respiratory support technologies, the mechanical ventilation treatment strategy for ARDS has also changed significantly;

[0003] The Respiratory Critical Care Medicine Group of the Chinese Medical Association's Respiratory Medicine Branch summarized and constructed 12 important problems commonly encountered in clinical practice based on the latest research progress at home and abroad, and formulated the "Guidelines for Mechanical Ventilation in Patients with Acute Respiratory Distress Syndrome" using the currently widely used evidence-based medicine method in the world - the GRADE method. Prone ventilation is an important guiding opinion given in this guideline. Prone ventilation refers to a nursing measure of a therapeutic position that helps patients take the prone position during mechanical ventilation to improve their oxygenation status. Prone ventilation can effectively improve the ventilation-perfusion ratio, alveolar recruitment, and good drainage of pulmonary and airway secretions under the action of gravity, reduce the compression of the heart and mediastinum on the dependent lung area, and effectively shorten the mechanical ventilation time. The "2019 ICS Guidelines: Management of Acute Respiratory Distress Syndrome" states that the prone ventilation time of prone ventilation patients should reach at least 12 hours per day, which can reduce the mortality rate of ARDS patients.

[0004] In order to decompress and protect the forehead and mandible parts of the ARDS patient's head from pressure, a U-shaped silicone pillow is usually placed under the patient's head for support. However, the conventional U-shaped pillow is not a special pillow for prone position. The patient's face is buried under the U-shaped pillow, resulting in poor ventilation and breathability; at the same time, the pitch angle and the size of the support area cannot be adjusted, and it cannot be adjusted specifically according to the patient's head size; and the patient wears an endotracheal tube through the mouth, and the endotracheal tube is not easy to fix and is prone to displacement or compression, thus affecting the normal drainage effect of the airway.

[0005] In view of this, the present invention is specifically proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a head and face support device for prone ventilation of patients, solving the problems raised in the above background art.

[0007] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A head and face support device for prone ventilation of patients, comprising: a base, a head support seat and a pillow body, wherein an arc-shaped notch is provided on the upper side of the base;

[0009] The head support seat is slidably fitted on the arc-shaped notch, two opposite head fixing blocks are slidably fitted on the upper side of the head support seat, and a telescopic fixing component connected to the two head fixing blocks is installed in the head support seat;

Detailed Description of the Specific Embodiment

[0033] Now, the present invention will be further described in detail with reference to the attached drawings.

[0034] Please refer to Figures 1-6 As shown, in this embodiment, a head and face support device for prone ventilation of patients is provided, including: a base 1, a head support seat 2, and a pillow body 3. An arc-shaped notch 9 is provided on the upper side of the base 1;

[0035] The head support seat 2 is slidably engaged with the arc-shaped notch 9. Two opposite head fixing blocks 5 are slidably engaged on the upper side of the head support seat 2. A telescopic fixing component 10 connected to the two head fixing blocks 5 is installed in the head support seat 2. Among them, the head support seat 2 is of a semi-circular structure;

[0036] A face placement groove 19 is provided on the upper side of the pillow body 3, a cloth tube groove 20 communicating with the face placement groove 19 is provided on the upper side of the pillow body 3, catheter positioning members 21 are provided on both sides of the cloth tube groove 20, and a plurality of ventilation holes are provided on the side of the face placement groove 19;

[0037] Among them, an angle adjustment assembly 8 is provided between the base 1 and the head support 2.

[0038] By providing the pillow body 3 on the head support 2, the patient can place the head on the pillow body 3. The setting of the face placement groove 19 does not exert pressure on the patient's mandible, cheeks, and eyes, reducing pressure-induced skin damage. Through the plurality of ventilation holes provided in the face placement groove 19, the ventilation and air permeability of the patient's face are ensured. Through the catheter positioning members 21 provided in the cloth tube groove 20, tracheal intubation can be placed to facilitate sputum suction, ensure the normal drainage of the airway, and reduce the situation where the tracheal intubation is compressed. The catheter positioning members 21 fix the tracheal intubation in the cloth tube groove 20, reducing the situation where the tracheal intubation is displaced; through the telescopic movement of the telescopic fixing assembly 10 in the head support 2, the two head fixing blocks 5 can move relative to each other on the head support 2, clamping and fixing the two sides of the patient's head, facilitating the adjustment of the two head fixing blocks 5 according to the size of the patient's head, so as to adapt to different patients. By providing the angle adjustment assembly 8 between the base 1 and the head support 2, the head support 2 slides in the arc-shaped notch 9, enabling the head support 2 to drive the angle of the patient's head to change through the two head fixing blocks 5, enabling the patient's head to move appropriately on the pillow body 3, thereby improving the comfort of the patient's head when lying prone.

[0039] As Figure 2 shown, a first inner cavity 11 is provided in the head support 2 of this embodiment, and the telescopic fixing assembly 10 is located in the first inner cavity 11;

[0040] As Figure 4 shown, specifically, the specific structure of the telescopic fixing assembly 10 is as follows: an elastic pad 1001 located in the first inner cavity 11, an annular groove 1002 opened on the inner side of the elastic pad 1001, a pull rope 1003 located in the annular groove 1002, and both ends of the pull rope 1003 penetrate through the head support 2; two sliding grooves are provided on the upper side of the head support 2, and two connecting rods 4 slidably matched in the two sliding grooves and fixedly connected to both sides of the elastic pad 1001 respectively, and the two connecting rods 4 are fixedly connected to the two head fixing blocks 5 respectively.

[0041] When it is necessary to fix the heads of different patients, pull both ends of the drawstring 1003 outward at the same time. The drawstring 1003 drives the elastic pad 1001 to contract in the first inner cavity 11. The contraction of the elastic pad 1001 drives the two connecting rods 4 to move relatively in the two chutes. The relative movement of the two connecting rods 4 drives the two head fixing blocks 5 to move relatively on the head support base 2. When the two head fixing blocks 5 move relatively and fit against the two sides of the patient's head, tie the two ends of the drawstring 1003, which can fix the positions of the two head fixing blocks 5, clamp and fix the two sides of the patient's head, and facilitate the adjustment of the two head fixing blocks 5 according to the size of the patient's head, so as to adapt to different patients.

[0042] As Figures 2-3 shown, a second inner cavity 14 is provided in the base 1 of this embodiment. The angle adjustment assembly 8 includes a worm 801 rotatably fitted in the second inner cavity 14, a plurality of teeth 802 installed at the bottom of the head support base 2 and meshed with the worm 801, and a turning handle 803 provided at the end of the worm 801 passing through the base 1. A clamping member 18 is provided between the turning handle 803 and the base 1; a rectangular chute 15 is opened at the end of the worm 801 passing through the base 1, and a rectangular slider 16 fixedly connected to one side of the turning handle 803 is slidably fitted in the rectangular chute 15. A first spring 17 is fixedly connected between the rectangular slider 16 and the rectangular chute 15;

[0043] As Figure 3 shown, specifically, the specific structure of the clamping member 18 is as follows: a plurality of clamping blocks 1801 arranged in a circumferential array on one side of the turning handle 803, and a plurality of clamping grooves 1802 opened on one side of the base 1 and corresponding to the plurality of clamping blocks 1801.

[0044] When it is necessary to adjust the angle of the patient's head, first pull the turning handle 803. The movement of the turning handle 803 drives the plurality of clamping blocks 1801 to move. After the plurality of clamping blocks 1801 move out of the plurality of clamping grooves 1802, then rotate the turning handle 803. The rotation of the turning handle 803 drives the rectangular slider 16 to rotate. The rotation of the rectangular slider 16 drives the worm 801 to rotate through the engagement with the rectangular chute 15. The rotation of the worm 801 drives the head support base 2 to slide in the arc-shaped notch 9 through the engagement with the plurality of teeth 802, which can change the angle of the patient's head driven by the head support base 2 through the two head fixing blocks 5, and can make the patient's head move appropriately on the pillow body 3, thereby improving the comfort of the patient's head when lying prone.

[0045] As Figure 6 shown, an arc-shaped limiting groove 12 is opened on the upper side of the arc-shaped notch 9 of this embodiment, and a limiting block 13 slidably fitted in the arc-shaped limiting groove 12 is installed at the bottom of the head support base 2;

[0046] Among them, the limiting block 13 and the arc-shaped limiting groove 12 are both convex structures, which enable the head support seat 2 to slide in the arc-shaped notch 9 through the limiting block 13 and the arc-shaped limiting groove 12, thereby improving the sliding stability of the head support seat 2 on the base 1.

[0047] As Figure 1 shown, on one side of each of the two head fixing blocks 5 in this embodiment, a protective pad 6 is installed, and an ear placement groove 7 is formed on one side of the protective pad 6;

[0048] Among them, the protective pad 6 can be a sponge pad or a rubber pad in the prior art, which can protect the patient's head. When the two head fixing blocks 5 move relatively to clamp the patient's head, the patient's ears enter the ear placement groove 7, reducing the situation where the two head fixing blocks 5 squeeze the ears.

[0049] As Figure 5 shown, specifically, the specific structure of the catheter positioning member 21 includes the following: a groove 2101 opened on one side of the pipe laying groove 20, an arc-shaped positioning block 2103 slidably fitted in the groove 2101, a second spring 2102 fixedly connected between the arc-shaped positioning block 2103 and the groove 2101, and a fillet 2104 provided at the upper side corner of the arc-shaped positioning block 2103.

[0050] When fixing the tracheal intubation in the pipe laying groove 20, first place the tracheal intubation into the pipe laying groove 20 from top to bottom. The tracheal intubation presses the fillet 2104 to retract the two arc-shaped positioning blocks 2103 into the two grooves 2101. When the tracheal intubation is located between the two arc-shaped positioning blocks 2103, the two arc-shaped positioning blocks 2103 clamp and fix the tracheal intubation through the elastic force of the second spring 2102, reducing the situation where the tracheal intubation is displaced and keeping the airway unobstructed.

[0051] The present invention is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present invention, as long as they have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention. The technologies, shapes, and structures not described in detail in the present invention are all well-known technologies.
