Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and variations in structure, method, or function that may be made by one of ordinary skill in the art based on these embodiments are within the scope of the present invention.

As shown in fig. 5, 6 and 10, the emergency face pillow of the present invention comprises: a face pillow module 11, a housing case 12 housing the face pillow module 11, and a pair of foldable flaps 13 fixed to the housing case 12. The three parts of the emergency face pillow can be separately produced and then organically combined in a bonding mode, a hinging mode and the like.

Referring to fig. 1 and 2, the construction of the accommodating case 12 of the rapid-facial pillow will be explained. The accommodating shell 12 is provided with a rectangular bottom plate 121, a pair of left and right baffle plates 122 vertically arranged along the long side direction, and a rear baffle plate 123 vertically arranged along the short side direction, an eye-nose opening 125 is hollowed in the middle of the rectangular bottom plate 121 along the long side direction, an accommodating cavity baffle plate 124 is vertically arranged around the periphery of the eye-nose opening 125 to form an eye-nose opening accommodating cavity 126, and the accommodating cavity baffle plate 124, the rectangular bottom plate 121, the left and right baffle plates 122 and the rear baffle plate 123 are integrally formed. In the emergency face pillow, the rectangular bottom plate 121 functions as a base to hold the face pillow. And two left and right guards 122 and one back guard 123 provided on both long sides and one short side of the rectangular base plate 121 limit the face pillow to a proper range of operation positions. An eye-nose opening 125 is provided in the face pillow along the long side direction. As can be seen, the eye-nose opening 125 has a contour substantially the same as the eye-nose opening of the human face, but has a cross-sectional area slightly larger than the eye-nose opening of the human face, so that the eye-nose opening can be adapted to different shapes of the eye-nose openings of the patient's face. And the eye-nose opening 125 is provided at approximately the middle of the rectangular bottom plate 121 so that the patient can properly place the face in the middle of the face pillow. A circle of accommodating cavity single plates are arranged around the edge of the eye-nose opening 125 of the rectangular bottom plate 121 and are perpendicular to the rectangular bottom plate 121, so that an eye-nose opening accommodating cavity 126 is formed, the eye-nose opening accommodating cavity 126 is fixedly formed in the middle of the accommodating cavity, and an eye-nose opening accommodating channel is provided for a patient in an operation process. During the procedure, if the patient wears a respiratory mask, is inserted with a gastric tube, or is taped to the eyes, the oronasal cavity 126 may provide the patient with a comfortable oronasal empty position without affecting the corresponding treatment of the oronasal opening. It should be noted that the material for manufacturing the accommodating case 12 has certain rigidity, and the usable material is plastic or alloy. Because the face pillow module 11 may be deformed when the head of the patient is supported on the emergency face pillow, if the rigidity of the housing case 12 housing the face pillow module 11 is too low to withstand the deformation and is broken and bent, the face pillow cannot perform the function of adapting to the posture of the patient.

Referring to fig. 1 to 4, specific dimensions of the accommodating case 12 will be described. It should be noted that the specific size of the housing 12 is selected according to the Chinese standard adult head and face size GB/T2428-1998. The utility model discloses an among the emergent face pillow, the concrete size of holding casing 12 is selected to be: the lengths L of the rectangular bottom plate 121 and the pair of left and right baffle plates 122 are the same and are 28-35 cm; the widths W of the rectangular bottom plate 121 and the rear baffle plate 123 are the same and are 18-25 cm; the heights H of the left baffle plate 122, the right baffle plate 122 and the rear baffle plate 123 are the same and are 15-25 cm. According to GB/T2428-1998, the average maximum head length is 223mm, and the length L of the rectangular base plate 121 and the left and right baffle plates 122 is the sum of the head length and the length of the face pillow module 11, and can be 28-35 cm, such as 28cm, 29cm, 30cm, 31cm, 32cm, 33cm, 34cm, 35 cm; the average maximum width of the head is 154mm, and the width W of the rectangular base plate 121 and the back baffle plate 123 is the sum of the width of the head and the width of the face pillow module 11, and may be 18-25 cm, such as 18cm, 19cm, 20cm, 21cm, 22cm, 23cm, 24cm, and 25 cm; the average value of the maximum height of the head is 184mm, the height H of the cavity baffle 124, the pair of left and right baffles 122 and the rear baffle 123 is 15-25 cm, such as 15cm, 16cm, 17cm, 18cm, 19cm, 20cm, 21cm, 22cm, 23cm, 24cm and 25cm, calculated by taking the maximum depth of the head supported in the emergency face pillow as 2/3 of the average value of the maximum height of the head.

Referring to fig. 3 and 5, the foldable flap 13 of the rapid-access pillow is illustrated. The long sides of the pair of foldable flaps 13 are connected to the long sides of the left and right flaps 122, respectively, by hinge mechanisms 131. As can be seen, the left and right flaps 122 of the accommodating case 12 have one lower bottom edge connected to the long edges of the rectangular bottom plate 121 and the other upper bottom edge connected to the lower bottom edges of the pair of foldable flaps 13. The pair of foldable flaps 13 can be rotated by 90 degrees by the hinge mechanism 131 with the long sides of the left and right flaps 122 as the rotation axis. The pair of foldable flaps 13 can be rotated in a range from abutting against the left and right flaps 122 to folding the face pillow module 11 toward the inside of the housing case 12. That is, when the pair of foldable flaps 13 are rotated to be perpendicular to the left and right flaps 122, they close the upper portion of the receiving cavity. The length of the lower bottom edge of one foldable baffle plate 13 is the same as that of the upper bottom edge of the rectangular bottom plate 121, and the width of the foldable baffle plate is half of that of the rectangular bottom plate 121 and is W/2. Thus, when the pair of foldable baffles 13 rotate towards the accommodating cavity and are perpendicular to the left and right baffles 122, the upper part of the accommodating shell 12 can be just covered. This achieves the effect of tightening the face pillow module 11. Common hinge mechanisms 131 include hinges and hinge rods.

Referring to fig. 5-9, the face pillow module 11 is illustrated. The face pillow module 11 includes a pressure cushioning material 113 and a shape memory material 114. The conventional pressure buffer material 113 includes: fibrous materials such as synthetic fibers, mineral fibers, asbestos, mineral wool; air bubble structure substances such as natural rubber, synthetic rubber, foamed plastic, eva foam, air bubble plastic film; corrugated paper, honeycomb paper, crepe paper, and the like. The pressure buffering material 113 needs to have good vertical elasticity, and can be rapidly restored to its original shape in a short time while bearing the weight of the human head without irreversible deformation. Among them, the foam pressure buffering material 113 is preferable. Commonly used shape memory materials 114 are: high molecular gel, silica gel, and shape memory polymer. The pressure buffering material 113 is engaged with the rectangular bottom plate 121, the back baffle 123, the left and right baffles 122 and the chamber baffle 124 and fills the space formed by the rectangular bottom plate 121, the back baffle 123, the left and right baffles 122 and the chamber baffle 124. Common joining methods are: bonding, suturing, chemical fusing, and the like. The pressure buffering material 113 is actually bonded to each baffle of the receiving cavity, so that the pressure buffering material 113 can substantially fill the space formed by the receiving cavity to form a uniform pressure buffering layer. By the pedestal action of the rectangular bottom plate 121, the pressure buffer layer can perform pressure buffering in the vertical direction; by the blocking action of the chamber baffle 124 and the left and right baffles 122, the pressure buffer layer can perform pressure buffering in the left and right directions; such a pressure buffering layer can be buffered in the front-rear direction by the blocking action of the tailgate 123. Thus, by this arrangement, the pressure cushioning material 113 can provide a stable pressure cushioning effect in all directions, and can be adapted to various head positions of the patient. For example, the patient may conventionally rest vertically on the emergency face pillow, with the pressure cushioning material 113 providing vertical pressure cushioning; the patient can rest on the emergency face pillow at a certain angle, for example, at an inclination of 30 degrees, at this time, the pressure buffering material 113 does not deform excessively left and right and can adapt to the head position of the patient at this time; the patient can also apply pressure to the back of the emergency face pillow and rest on the emergency face pillow, and at the moment, the pressure buffering material 113 can not deform excessively back and forth and can adapt to the head position of the patient. The pressure buffering material 113 is bent and cut out a forehead groove 111 corresponding to the forehead of the head from the upper edge of the eye receiving chamber of the eye-nose receiving chamber 126 in the length direction of the rectangular bottom plate 121, a maxillary groove 112 corresponding to the maxillary of the head from the lower edge of the eye receiving chamber of the eye-nose receiving chamber 126 in the length direction of the rectangular bottom plate 121, and the shape memory material 114 is joined to the curved surfaces of the forehead groove 111 and the maxillary groove 112. The curved surface length of the curved surface is 3-8 cm, the curved surface is designed according to the purpose of the emergency face pillow, for example, when the emergency face pillow is used in war, men are more, and then the curved surface length of the curved surface can be relatively large, for example, 6cm, 7cm and 8 cm. For intraoperative emergency temporary change of head position, for both men and women, the length of the curved cut surface may be relatively small, e.g., 3cm, 4cm, 5cm, etc. The maximum length L2 of the forehead groove 111 is 10-15 cm, such as 10cm, 11cm, 13cm, 14cm and 15 cm; the maximum width W2 is 10-15 cm, such as 10cm, 11cm, 13cm, 14cm, 15 cm; the maximum length L3 of the maxillary groove 112 is 5-10 cm, such as 5cm, 6cm, 7cm, 8cm, 9cm, 10 cm; for example, the maximum width W3 is 5 to 10cm, for example, 5cm, 6cm, 7cm, 8cm, 9cm, 10 cm. The frontal recess 111, the ocular-nasal cavity 126 and the maxillary recess 112 form a plane substantially the same as a human face. When the pair of foldable flaps 13 folds the pressing face pillow module 11 toward the inside of the accommodation case 12, the pressure buffering material 113 reaches the maximum compression amount. That is, the pressure cushioning material 113 cannot be further compressed when compressed by the pair of foldable flaps 13, so that the emergency face pillow can accommodate the maximum volume of the pressure cushioning material 113. When the pair of foldable flaps 13 are unfolded to abut the pair of left and right flaps 122, the pressure cushioning material 113 reaches a maximum extension, i.e., when the face pillow module 11 is at a maximum compression, the cavity flap 124 vertically engages a portion of the face pillow module 11, and the face pillow module 11 above the cavity flap 124 is not secured in place by any flap engagement, which is configured to accommodate movement of the patient in left and right anterior and posterior positions. It is noted that the pressure applied to the pressure buffering material 113 by the head is smaller than the pressure applied to the pressure buffering material 113 by the pair of foldable flaps 13, otherwise the head may press the pressure buffering material 113 to an irreversible deformation.

Referring to fig. 5, 6 and 10, it should be noted that the cross section formed by the pair of foldable flaps 13 and the left and right flaps 122 is a right trapezoid. That is, the pair of foldable flaps 13 and the left and right flaps 122 are respectively right-angled trapezoids having the same angle of inclination and the angles of inclination of the left and right flaps 122 are opposite to the rear flap 123. The cross section of such a right trapezoid is substantially the same as the cross section of the face pillow module 11 in the longitudinal direction. That is, the face pillow module 11 has a substantially rectangular cross-section, a height H1 of H + W/2, for example, 24cm, 25.5cm, 27cm, 29.5cm, 31cm, 32.5cm, 34cm, and an inclination angle A of the rectangular cross-section of 20 to 30 degrees. That is, the face pillow module 11 has a plane parallel to the rectangular base plate 121 and a slope at an angle to the rectangular base plate 121 facing the patient's face. In addition, as shown in fig. 1, the maximum length L1 of the eye-nose-mouth cavity 126 is 15-20 cm, for example, 15cm, 16cm, 17cm, 18cm, 19cm, 20 cm; the maximum width W1 is 10-20 cm, such as 10cm, 11cm, 12cm, 13cm, 14cm, 15cm, 16cm, 17cm, 18cm, 19cm, 20 cm; the height of the chamber baffles 124 of the eye-nose mouth chamber 126 decreases in sequence to form the same inclination angle a as the pair of left and right baffles 122 and the maximum height of the chamber baffles 124 is H. That is, the inclined plane formed by the cavity baffle 124 is parallel to the inclined plane of the face pillow module 11, so that when the patient is rested on the emergency face pillow at a certain angle, the eye, nose and mouth cavity 126 can adapt to the body position of the patient, and a comfortable operation environment is provided. The cross-sectional shapes of the pair of foldable flaps 13 and the left and right flaps 122 are designed according to the body position of a human face when the human face is held by the face pillow. When the face of a person is rested on the face pillow, the face and the body form a certain angle. In order to ensure that the patient performs the operation in a comfortable position, the pair of foldable flap 13 and the left and right flaps 122 that hold the sides of the face pillow module 11 are also designed to have a certain inclination angle. Meanwhile, the pair of left and right shutters 122 and the pair of foldable shutters 13 are rounded, so that the right angles of the pair of left and right shutters 122 and the pair of foldable shutters 13 can be prevented from injuring the face.

In addition, as shown in fig. 3, 5 and 8, two fixing bands 14 are connected and arranged at two ends of the upper edges of the pair of foldable baffles 13 from left to right, respectively correspond to the eyes and the mouth, and press and fix the head around the back head of the head, so that the head of the patient can be prevented from moving unnecessarily.

The utility model discloses emergent face pillow is owing to can be according to the shape that patient's head position changed the face pillow module and have good pressure cushioning effect, consequently is particularly suitable for and changes patient position application temporarily in medical treatment, urgent treatment and the operation process during the wartime. The utility model discloses emergent face pillow also is applicable to the hospital operating room, can replace the position pillow that a plurality of combinations used, and the function improves, and the equipment reduces.

Having described the structure of the emergency face pillow of the invention, it should also be noted that a person skilled in the art may, without departing from the technical field and scope of the invention, make modifications and/or additions of parts to the structure described above, realising many other equivalent forms, which incorporate the corresponding features set forth in the claims and are therefore within the scope of protection defined thereby.
