Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical apparatus and instruments, and particularly relates to a headrest for prone position ventilation. BACKGROUND

[0002] Prone position ventilation refers to placing a patient in a prone position when mechanical ventilation is implemented to increase the expansion of the patient's back lung alveoli, thereby better improving the patient's oxygenation state, and is an important lung protection ventilation strategy. Research shows that the position can improve the patient's arterial oxygen saturation (SaO2), arterial oxygen partial pressure (PaO2) and oxygenation index (PaO2 / FiO2, wherein FiO2 is the inhaled oxygen concentration) and other physiological indexes.

[0003] In use, prone position ventilation is usually more than 12 hours, the patient's face is downward, and the existing headrest has limited limitation on the patient's head, so that the patient's head is prone to sliding or shifting during use, thereby affecting the treatment effect. Therefore, how to design a headrest for prone position ventilation to better limit the patient's head so that the patient's head is not easy to shift becomes a technical problem that technicians in the field urgently need to solve.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0024] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0025] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0026] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0027] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a head pillow for prone ventilation, which includes a memory foam head pillow body 11, a support plate 51, a head fixation strap 31, a chin fixation strap 41, and an adjustment strap 21. The memory foam head pillow body 11 is an annular structure with an adjustment opening 13 on the lower side. The central cavity 12 of the memory foam head pillow body is used to accommodate the patient's face. The adjustment strap 21 is used to connect the left and right sides of the adjustment opening. The head fixation strap 31 for fixing the patient's head is disposed opposite to each other on the outer wall surfaces of the left and right sides of the memory foam head pillow body 11, and the chin fixation strap 41 for fixing the patient's chin is also disposed opposite to each other. The head fixation strap 31 extends horizontally, and the chin fixation strap 41 extends vertically. The bottom surface of the memory foam head pillow body is disposed on the support plate 51, and the shape of the support plate is adapted to the shape of the memory foam head pillow body.

[0028] The headrest for prone position ventilation provided by the embodiment of the utility model, when in use, after the face of the patient is placed in the middle cavity 12, the two head fixing bands 31 are connected to fix the head of the patient, the two lower jaw fixing bands 41 are connected to fix the lower jaw of the patient, so that the whole head region of the patient is fixed well, so that the whole head region of the patient is well positioned, and the patient's head is not easy to displace due to sliding or shifting, so that the treatment effect is not affected. At the same time, according to the face size of different patients, the distance between the left and right ends of the adjusting opening on the memory cotton headrest main body is adjusted to adjust the size of the middle cavity 12, and then the two ends are connected by the adjusting band 21 to avoid the size from changing when in use, so that the headrest for prone position ventilation can be well adapted to different patients, and the universality is good.

[0029] Further, the bottom of the memory cotton headrest main body and one end of the supporting plate close to the adjusting opening are provided with left and right through opening holes 15, the opening direction of the opening hole 15 is vertically downward, and the opening hole is communicated with the middle cavity. By the opening hole, each pipeline worn on the face of the patient can be conveniently worn out, and the hand can also be conveniently inserted into the opening hole and the middle cavity to adjust the pipeline.

[0030] Specifically, the two head fixing bands 31 are connected to the middle positions of the left and right side outer wall surfaces of the memory cotton headrest main body 11 respectively, so that after the two head fixing bands are connected, the head of the patient can be better fixed.

[0031] Preferably, the upper end of the lower jaw fixing band 41 is connected to the inner end of the head fixing band 31 close to the memory cotton headrest main body. Meanwhile, the inner sides of the two lower jaw fixing bands can be connected to the lower parts of the left and right side outer wall surfaces of the memory cotton headrest main body respectively, so that the two lower jaw fixing bands can be fixed more firmly and reliably.

[0032] Further, the head fixing band 31 and the lower jaw fixing band 41 on the same side of the memory cotton headrest main body are provided with a connecting band 61. By the connecting band, the inner end of the head fixing band and the upper end of the lower jaw fixing band are connected, so that the connecting band, the inner end of the head fixing band and the upper end of the lower jaw fixing band form a right triangle structure, so that the connection between the head fixing band 31 and the lower jaw fixing band 41 is improved in firmness.

[0033] Preferably, the head fixing band 31, the lower jaw fixing band 41 and the adjusting band 21 are all Velcro bands, which can be conveniently connected by being adhered to each other, so that the connection operation is more convenient, and the fixation of the whole head region of different patients can be more conveniently realized.

[0034] Further, the outer layer of the memory cotton head pillow body 11 is a detachable pillowcase. With this scheme, the pillowcase can be detached for cleaning and disinfection. Two pillowcases can be used, one of which is in use and the other is being cleaned and disinfected, so as to better meet the use requirements and facilitate repeated use. Specifically, the pillowcase can be made of milk silk fabric. The head fixing band, the lower jaw fixing band and the adjusting band are all connected to the pillowcase and can be detached together with the pillowcase for cleaning and disinfection. Preferably, the detachable pillowcase is realized by providing a zipper 14.

[0035] Preferably, the top of the memory cotton head pillow body 11 is concave in the middle and convex at both ends, and the height of the upper end convexity is slightly higher than that of the lower end convexity, so that it can better fit the face of the patient, and the concave part can also play a certain limiting role.

[0036] Specifically, the support plate 51 is a polypropylene plate, referred to as a PP plate, so as to better support the memory cotton head pillow body, improve the overall strength of the prone position ventilation headrest, avoid the height being too low after being pressed, and effectively avoid the folding of the pipelines. At the same time, the overall height of the prone position ventilation headrest can be increased, such as being designed as 40 cm, so as to provide sufficient height space for the pipelines and make the pipelines less likely to be folded. The memory cotton head pillow body and the support plate can be integrated or in a split structure.

[0037] The material of the memory cotton head pillow body of the utility model is memory cotton, so that the head pillow body is relatively soft and can effectively reduce the occurrence of pressure injuries. At the same time, it is cheap and has low cost.

[0038] While specific embodiments of the application have been described in detail, those familiar with the art will appreciate that the examples given are by way of example and are not meant to limit the scope of the application. Those skilled in the art will recognize or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the application described herein. It is therefore intended that the scope of the application be determined by the following claims.
