Description

Technical Field

[0001] The utility model belongs to the technical field of medical auxiliary devices, in particular to a facial pressure injury prevention device for a patient in a prone position. Background Art

[0002] Patients in the prone position usually need a head pad to support and protect their heads. Currently, many hospitals use prone head pads with T-shaped through holes. The shape of the T-shaped through holes is close to the shape of the mouth, nose and eyes of the human face, which is convenient for accommodating the mouth, nose and eyes of prone patients, keeping the patient's breathing circuit unobstructed and avoiding eye pressure; at the same time, it increases the contact area between the head pad and the patient's face and reduces the pressure on the patient's face.

[0003] A Chinese patent with the authorization number CN220327619U discloses a prone head pad protective cover. By providing a protective airbag, the protective airbag is filled with air and has a smooth inner wall. The upper surface of the protective airbag moves with the patient's face, which reduces the shear force between the upper surface of the prone head pad and the patient's face, thereby reducing the risk of pressure sores. However, this technical solution still has the following defects:

[0004] Although the upper surface of the protective airbag moves with the patient's face to reduce the shear force on the face, the face of the patient in the prone position will always be in contact with the airbag. Under the reaction force of the pressure, the patient's face will always be compressed. Maintaining the prone position for a long time can still easily cause pressure injuries to the patient's face. Utility Model Content

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a facial pressure injury prevention device for patients in a prone position, which solves the problem that although the existing protective airbag can reduce the shear force on the patient in a prone position, lying prone for a long time still easily causes pressure injuries on the face.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the utility model, a facial pressure injury prevention device for a patient in a prone position is proposed, comprising a head pad and a T-shaped through hole arranged at the center of the head pad, a protective part is arranged on the outside of the head pad, the protective part comprises a protective cover and a base, the top of the base is fitted with the bottom of the head pad, the protective cover is sleeved on the head pad, and an opening corresponding to the T-shaped through hole is opened on the top of the protective cover, a protective airbag arranged along the circumference of the opening is installed on the top of the protective cover, a first trachea and a second trachea arranged along the circumference of the opening are arranged below the protective airbag, and the first trachea and the second trachea are both embedded and installed on the top of the protective cover, a plurality of first interfaces and a second interface are respectively installed on the top of the first trachea and the second trachea, and the first interface and the second interface are staggered, the inner cavity of the protective airbag is divided into a plurality of air chambers respectively connected with the first interface and the second interface, and an air intake mechanism is installed between the first trachea and the second trachea.

[0007] As a further technical solution of the utility model, the air intake mechanism includes a tee, on which an air intake pipe, a first branch pipe and a second branch pipe are respectively installed, the other ends of the first branch pipe and the second branch pipe are respectively connected to the first air pipe and the second air pipe, and valve assemblies are installed on the first branch pipe and the second branch pipe.

A protective member 3 is arranged on the outer side of the head pad 1. The protective member 3 comprises a protective cover 301 and a base 302. The top of the base 302 fits with the bottom of the head pad 1. A groove 15 corresponding to the T-shaped through hole 2 is provided on the top of the base 302 to facilitate receiving and collecting saliva of the patient in the prone position. The cross-sectional shape of the groove 15 is the same as that of the T-shaped through hole 2. A baffle 16 is fixedly installed on the top of the base 302, and a recess 17 for inserting the baffle 16 is provided on the bottom of the head pad 1 to facilitate the head pad 1 to be placed on the base 302 without sliding, which is beneficial to improving the overall stability.

[0022] The protective cover 301 is mounted on the head pad 1, and an opening corresponding to the T-shaped through hole 2 is provided on the top of the protective cover 301. In the present embodiment, the protective cover 301 is made of waterproof nylon cloth, which can isolate the patient's saliva and sweat, and has certain mildew resistance and flame retardancy. A Velcro 18 is installed between the protective cover 301 and the base 302, which is not only conducive to improving the stability of the position of the protective cover 301 after installation, but also convenient for disassembling the protective cover 301 as needed. The fur surface of the Velcro 18 is installed on the outer wall of the base 302, and the hook surface of the Velcro 18 is installed near the bottom of the protective cover 301.

[0023] A protective airbag 4 arranged along the circumference of the opening is installed on the top of the protective cover 301, and a first air pipe 5 and a second air pipe 6 arranged along the circumference of the opening are provided below the protective airbag 4, and the first air pipe 5 and the second air pipe 6 are both inlaid and installed on the top of the protective cover 301, and a plurality of first interfaces and a second interface are respectively installed on the top of the first air pipe 5 and the second air pipe 6, and the first interface and the second interface are staggered. The inner cavity of the protective airbag 4 is divided into a plurality of air chambers respectively connected with the first interface and the second interface, and an air intake mechanism is installed between the first air pipe 5 and the second air pipe 6 to facilitate the control of air intake and exhaust of the first air pipe 5 and the second air pipe 6 as needed.

[0024] The air intake mechanism includes a tee 7, on which an air intake pipe 8, a first branch pipe 9 and a second branch pipe 10 are installed respectively. The air intake pipe 8 is connected to the output end of an external air pump (not shown in the figure), and the other ends of the first branch pipe 9 and the second branch pipe 10 are connected to the first air pipe 5 and the second air pipe 6 respectively, and valve assemblies are installed on the first branch pipe 9 and the second branch pipe 10;

[0025] The valve assembly includes a first solenoid intake valve 11 and a second solenoid intake valve 12 respectively installed on the first branch pipe 9 and the second branch pipe 10. The first solenoid intake valve 11 and the second solenoid intake valve 12 are both arranged close to the tee 7. The first solenoid exhaust valve 13 and the second solenoid exhaust valve 14 are respectively installed on the pipe walls of the first branch pipe 9 and the second branch pipe 10. In this embodiment, the first solenoid intake valve 11, the second solenoid intake valve 12, the first solenoid exhaust valve 13, the second solenoid exhaust valve 14 and the air pump are respectively connected to an external controller (not shown in the figure) through wires.

[0026] The working principle of the utility model is as follows: an external controller is used to control the air pump and the first electromagnetic air inlet valve 11 to open, and the second electromagnetic air inlet valve 12 and the first electromagnetic exhaust valve 13 to close, so that the gas can be introduced into the first trachea 5 through the first branch pipe 9, thereby expanding the air chamber in the protective airbag 4 connected to the first interface on the first trachea 5, so as to support the patient's face. After the support set time, the controller controls the first electromagnetic air inlet valve 11 and the second electromagnetic exhaust valve 14 to close, and the second electromagnetic air inlet valve 12 and the first electromagnetic exhaust valve 13 to open, so that the gas output by the air pump can be introduced into the second trachea 6 through the second branch pipe 10, thereby expanding the air chamber in the protective airbag 4 connected to the second interface on the second trachea 6, and when the first electromagnetic exhaust valve 13 is opened, the air chamber previously connected to the first interface and expanded will be exhausted and reset, so that it will no longer fit the patient's face. Such repeated cycles can intermittently support different parts of the patient's face to prevent pressure injuries caused by the same part of the face being always under pressure.

[0027] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
