Description

Technical Field

[0001] This invention relates to the field of auxiliary face support technology for medical surgery, and more specifically, to a prone face support device. Background Technology

[0002] During some medical procedures, patients may need to maintain a prone position. For patients in this position during surgery, medical personnel typically use a facial support device to provide stable support for the patient's head. This facial support device usually includes a placement cavity for the face.

[0003] When using existing facial support devices, due to the differences in head size among patients, it is difficult to achieve a good fit between the placement cavity of the facial support device and the face of each patient. The patient's facial position is prone to deviation and is inconsistent with the body position. Furthermore, when patients lie prone in the placement cavity for a long time, the facial skin at the point where the patient lies prone may experience poor blood flow due to prolonged pressure.

[0004] Based on the above situation, medical staff need to observe the patient's head condition every once in a while and take manual measures according to the observation, which increases the workload of medical staff. Summary of the Invention

[0005] The present invention provides a prone facial support device that overcomes some or all of the defects of the prior art.

[0006] According to the present invention, a prone facial support device includes a device body, the device body including a face support, a placement cavity for placing a human face is formed at the face support; a top area for cooperating with the forehead of the human face is formed in the placement cavity; a first area and a second area corresponding to both sides of the forehead are formed in the top area.

[0007] A first airbag installation area is formed in both the first and second regions. The first airbag installation area includes a region A at the top and a region B at the bottom. An airbag A for inflating and pressing against the upper part of the forehead is installed in region A, and an airbag B for inflating and lifting the forehead is installed in region B.

[0008] Specifically, when using the device of this invention, the patient first lies prone in the placement cavity of the face support. Since the head size varies from patient to patient, medical staff can control the expansion of the A-bag to position it against the left and right sides of the forehead. By using the A-bag against the left and right sides of the forehead, initial facial positioning is achieved to prevent tilting; furthermore, it is better suited for different patients, requiring only control of the degree of expansion of the A-bag.

[0009] Once the inflation level of balloon A is adjusted, it requires no further adjustment throughout the surgical procedure; it simply needs to remain in this state. Since patients are mostly under anesthesia during surgery, the face in this invention maintains a relatively stable position through balloon A, aligning with the patient's body position. This eliminates the need for medical staff to intermittently and repeatedly observe the patient's facial position during the procedure, significantly reducing their workload and allowing them to better focus on the surgical process.

[0010] In addition, because some surgeries take a long time and patients have serious underlying diseases, medical staff need to observe the patient's facial condition more closely to prevent poor blood circulation or even pressure sores caused by prolonged pressure on the patient's face.

[0011] To address this issue, the device body of this invention can be directly controlled via the B-airbag. When the B-airbag inflates, it lifts the forehead of the face. In other words, by simply controlling the degree of inflation of the B-airbag, the pressure position between the face and the B-airbag can be adjusted. At the same time, the position of the face can also be directly adjusted. After the position of the face is adjusted, the pressure position between the face and other areas in the placement cavity will also change, thereby effectively preventing the face from pressing against the placement cavity in the same position for a long time.

[0012] This invention allows for adjustment of the compression situation by controlling the B-balloon, effectively reducing the probability of facial erythema or even pressure sores caused by pressure. Therefore, the device itself can significantly reduce the workload of medical staff while ensuring the patient's physical condition.

[0013] Preferably, a mouth and nose opening is formed inside the cavity, which corresponds to the mouth and nose of the human face. A head region is formed on one side of the mouth and nose opening, and a jaw region is formed on the other side of the mouth and nose opening to cooperate with the jaw part of the human face.

[0014] Preferably, the oronasal inlet is also used to house the B trachea, which passes through the oronasal inlet and connects to the B airbag. The interface between the B trachea and the B airbag is located on the bottom of the B airbag near the oronasal inlet. The B trachea is used to connect the B airbag to the air source. The A airbag is connected to the A trachea for connecting to the air source. The interface between the A trachea and the A airbag is located on the top of the A airbag near the inner wall of the placement cavity.

[0015] Preferably, the mouth and nose opening includes a mouth opening corresponding to the mouth of the human face, and the lower jaw region located on both sides of the mouth opening forms a third region and a fourth region respectively; the third region and the fourth region are respectively used to correspond to the left and right sides of the human face.

[0016] Preferably, a second airbag mounting area is formed in both the third and fourth regions. The second airbag mounting area includes a region C located on the outer side and a region D located on the inner side. Region C is used to mount airbag C, which is inflated to rest against the lower jaw of the face. Region D is used to mount airbag D, which is inflated to support the bottom of the jaw upwards. The bottom of both airbags C and D is connected to an air tube for connecting to an air source.

[0017] Preferably, the first airbag installation area also includes area E, which is located between areas A and B. An airbag E is installed in area E. An area F is formed between area E and area A. A support plate is installed in area F, and airbag A is installed on the top of the support plate. An upwardly extending T-shaped groove is formed on the inner wall of the placement cavity. A sliding block is connected to one end of the support plate, and the sliding block slides in fit with the groove. Airbag E is used to inflate to push the support plate and airbag A upward.

[0018] Preferably, the E-airbag is connected to an E-air tube for connecting to an air source, and the interface between the E-air tube and the E-airbag is located at the lower part of the E-airbag.

[0019] Preferably, the E airbag includes an E1 airbag and an E2 airbag that share the same air chamber, with the E1 airbag located on the side near the support plate and the E2 airbag located on the side near the B airbag.

[0020] Preferably, the E1 airbag is used in conjunction with the support plate, and the E1 airbag is used to inflate to lift the support plate; the E2 airbag is used to inflate to rest against the lower side of the forehead.

[0021] Preferably, the B airbag includes two independent airbag groups, B1 and B2; each airbag unit of the B1 and B2 airbag groups is staggered; the B1 and B2 airbag groups are used to work alternately to adjust the support position. Attached Figure Description

[0026] To further understand the content of this invention, the invention will be described in detail with reference to the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention.

[0027] Example 1

[0028] This embodiment provides a prone facial support device, combined with Figure 1 The device includes a device body 100, which includes a face support 110. A placement cavity 120 for placing a human face is formed in the face support 110. A top area 130 for cooperating with the forehead of the human face is formed in the placement cavity 120. A first area 140 and a second area 150 corresponding to both sides of the forehead are formed in the top area 130.

[0029] First airbag mounting areas are formed in both the first region 140 and the second region 150. The first airbag mounting area includes a top region A 141 and a bottom region B 142. An A airbag 210 for inflating to abut against the upper part of the forehead is installed in region A 141, and an B airbag 220 for inflating to lift the forehead is installed in region B 142.

[0030] Specifically, in this embodiment, when using the device body 100, the patient first lies prone in the placement cavity 120 of the face support 110. Since the head size varies from patient to patient, medical staff can control the inflation of the A-bag 210 so that it rests against the left and right sides of the forehead. By using the A-bag 210 against the left and right sides of the forehead, initial facial positioning is achieved to prevent tilting; furthermore, it is better suited for different patients, requiring only control of the inflation degree of the A-bag 210.

[0031] Once the inflation level of airbag 210 is adjusted, it requires no further adjustment throughout the surgical procedure; it simply needs to remain in this state. Since patients are mostly under anesthesia during surgery, in this embodiment, the face can maintain a relatively stable position through airbag 210, aligning with the patient's body position. This eliminates the need for medical staff to intermittently and repeatedly observe the patient's facial position during the procedure, significantly reducing their workload and allowing them to better focus on the surgical process.

[0032] In addition, because some surgeries take a long time and patients have serious underlying diseases, medical staff need to observe the patient's facial condition more closely to prevent poor blood circulation or even pressure sores caused by prolonged pressure on the patient's face.

[0033] In response to this situation, the device body 100 in this embodiment can be directly controlled by the B airbag 220. After the B airbag 220 inflates, it will lift the forehead of the face. That is, by simply controlling the degree of inflation of the B airbag 220, the pressure position between the face and the B airbag 220 can be adjusted. At the same time, the position of the face can also be directly adjusted. After the position of the face is adjusted, the pressure position between the face and other areas in the placement cavity 120 will also change, thereby effectively preventing the face from pressing against the placement cavity 120 in the same position for a long time.

[0034] This embodiment allows for adjustment of the compression situation by controlling the B airbag 220, effectively reducing the probability of erythema or even pressure sores on the patient's face due to compression. Therefore, the device body 100 in this embodiment can better reduce the workload of medical staff while ensuring the patient's physical condition.

[0035] In this embodiment, a mouth and nose passage 160 is formed in the placement cavity 120. The mouth and nose passage 160 is used to correspond to the mouth and nose of the human face. A head region is formed on one side of the mouth and nose passage 160, and a jaw region 170 is formed on the other side of the mouth and nose passage 160 to cooperate with the jaw region of the human face.

[0036] Furthermore, the placement cavity 120 in this embodiment is provided with an oronasal inlet 160. During surgery, the oronasal inlet 160 can usually facilitate the insertion of the endotracheal tube into the patient's trachea through the patient's mouth or nose to assist the patient's breathing, relieve airway obstruction, and aspirate tracheal secretions.

[0037] In this embodiment, the nasal inlet 160 is also used to arrange the B trachea 180, which is used to pass through the nasal inlet 160 and connect to the B airbag 220. The interface between the B trachea 180 and the B airbag 220 is located on the bottom of the B airbag 220 near the nasal inlet 160. The B trachea 180 is used to connect the B airbag 220 and the air source. The A airbag 210 is connected to the A trachea 190 for connecting to the air source. The interface between the A trachea 190 and the A airbag 210 is located on the top of the A airbag 210 near the inner wall of the placement cavity 120.

[0038] Specifically, in this embodiment, the B trachea 180 is connected to the bottom of the B airbag 220 through the mouth and nose inlet 160. In this way, when the air source inflates the B airbag 220 through the B trachea 180, the expansion process of the B airbag 220 starts from the bottom and spreads out. In this way, the face will be naturally lifted upward during the expansion process.

[0039] Furthermore, regarding the A airbag 210, since the air inlet of the A airbag 210 is located at the top of the A airbag 210, when the air source inflates the A airbag 210 through the A air tube 190, the expansion process of the A airbag 210 starts from the top and spreads out. In this way, during the expansion process, it will naturally form an inward tendency to press against the face.

[0040] In this embodiment, the mouth and nose opening 160 includes a mouth opening 161 corresponding to the mouth of the human face, and the jaw region 170 is located on both sides of the mouth opening 161, forming a third region 171 and a fourth region 172 respectively; the third region 171 and the fourth region 172 are respectively used to correspond to the left and right faces.

[0041] In this embodiment, a second airbag mounting area is formed in both the third region 171 and the fourth region 172. The second airbag mounting area includes a region C 1711 located on the outer side and a region D 1712 located on the inner side. Figure 3 Region C 1711 is used to install C airbag 310, which is inflated to rest against the lower jaw of the face; Region D 1712 is used to install D airbag 320, which is inflated to support the lower jaw; the bottom of both C airbag 310 and D airbag 320 is connected to an air tube for connecting to an air source.

[0042] Understandably, both airbag A 210 and airbag B 220 are used to abut against the forehead of the face. Further, for the chin area, this embodiment uses airbag C 310 and airbag D 320 for control. When the face is placed in the placement cavity 120, medical personnel can inflate airbag C 310. Since the chin is triangular, the inflated airbags C 310 located on both sides of the mouth opening 161 can abut against the left and right sides of the chin, thus providing abutment and limiting the chin. Combined with airbag A 210 abutting against the forehead, airbags A 210 and C 310 can form abutment points at the four corners of the face, ensuring facial stability.

[0043] Furthermore, the C-balloon 310 can be adapted to different patients by controlling the degree of inflation. Moreover, by abutting against the chin, the C-balloon 310 can also lift the face forward to prevent it from sliding outward. Especially for some younger patients, the C-balloon 310 can move the face forward to prevent the patient's forehead from falling out of the inflation area of ​​the A-balloon 210.

[0044] Furthermore, the D-balloon 320 can work in conjunction with the B-balloon 220 to adjust the patient's facial position by controlling the degree of inflation, thereby controlling the position and pressure point. Moreover, the B-balloon 220 and D-balloon 320, after elevating the face, can effectively prevent compression between the face and the B-trachea 180 and D-trachea.

[0045] In this embodiment, the first airbag installation area also includes an E region 143, which is located between an A region 141 and a B region 142. An E airbag 260 is provided in the E region 143, and an F region 144 is formed between the E region 143 and the A region 141. Figure 2 A tray 230 is provided in area F 144, and airbag A 210 is installed on top of tray 230; a T-shaped groove 240 extending upward is formed on the inner wall of placement cavity 120, and a sliding block is connected to one end of tray 230, and the sliding block and the groove 240 slide together; airbag E 260 is used to inflate to push tray 230 and airbag A 210 upward.

[0046] Specifically, since airbag A 210 will rest against the forehead of the face, if airbag B 220 lifts the face upwards to a large extent, there may be excessive pressure between the forehead and airbag A 210.

[0047] In response to this situation, this embodiment provides a sliding support plate 230. The support plate 230 can provide an installation position for the A airbag 210 and can carry the A airbag 210 upward. After the A airbag 210 moves upward, its inward pressing tendency will not change, and it can still maintain a close contact with the forehead of the face, and can effectively avoid the situation of pressing too tightly against the patient's forehead.

[0048] In this embodiment, combined with Figure 1 The E-airbag 260 is connected to an E-air tube 1110 for connecting to an air source. The interface between the E-air tube 1110 and the E-airbag 260 is located at the lower part of the E-airbag 260.

[0049] In this embodiment, combined with Figure 2 Airbag 260 includes airbag 261 and airbag 262 sharing the same air chamber. Airbag 261 is located on the side near the support plate 230, and airbag 262 is located on the side near airbag 220.

[0050] In this embodiment, the E1 airbag 261 is used to cooperate with the support plate 230, and the E1 airbag 261 is used to inflate to lift the support plate 230; the E2 airbag 262 is used to inflate to rest against the lower side of the forehead.

[0051] Specifically, in this embodiment, airbags E1 261 and E2 262 inflate synchronously. Airbag E1 261 can cooperate with the aforementioned support plate 230 to lift the support plate 230. Furthermore, the support plate 230 only needs to be lifted when airbag B 220 is lifted. However, when airbag B 220 is lifted, it can only lift the bottom of the forehead. At this time, while airbag E1 261 inflates to lift airbag A 210, airbag E2 262 will also inflate to support the side of the forehead, thereby cooperating with airbag B 220 to make the position of the face more stable.

[0052] In this embodiment, combined with Figure 4 Airbag 220 includes independent airbag groups B1 221 and B2 222; each airbag unit of airbag group B1 221 and airbag group B2 222 is staggered; airbag groups B1 221 and B2 222 are used to work in turn to adjust the support position.

[0053] Furthermore, with the lateral support of the E2 airbag 262, the B airbag 220 can then operate alternately with the B1 airbag assembly 221 and the B2 airbag assembly 222. The B airbag 220 has a B1 tube 410 and a B2 tube 420 inside. The B1 tube 410 is used to inflate the B1 airbag, and the B2 tube 420 is used to inflate the B2 airbag.

[0054] During the alternation, the E2 airbag 262 can still provide support, thus buffering and providing auxiliary support for the alternation process of the B1 airbag group 221 and the B2 airbag group 222, thereby achieving a smooth alternation when the B1 airbag group 221 and the B2 airbag group 222 change their pressure positions.

[0055] Furthermore, in this embodiment, the B airbags 220 and D airbags 320 corresponding to the left and right faces respectively can also cooperate with each other. When the B airbags 220 and D airbags 320 corresponding to the left face inflate, while the B airbags 220 and D airbags 320 corresponding to the right face do not inflate, the face can be tilted by the airbags. Thus, when medical staff observe the patient's face through the mouth and nose opening 160, the left and right tilt of the face can be controlled, and the medical staff can observe all positions of the face in one observation, thereby reducing the workload of the medical staff.

[0056] In general, this embodiment ensures the stability of the patient's facial position through airbags A 210 and C 310, and then uses airbags B 220 and D 320 to intermittently change the pressure position of the patient's face; thus, the airbags can be used to assist different patients, and medical staff do not need to intermittently observe the patient's face multiple times, which greatly reduces the workload of medical staff.

[0057] Furthermore, the B-bag 220 and D-bag 320 on the left and right sides of the face can alternately inflate to achieve non-contact tilting of the face. This allows medical staff to observe the main pressure points of the patient's face non-contactly during a single observation. Since medical staff may have disinfection issues after contacting the patient, this method can ensure complete facial observation while significantly reducing the workload of medical staff. In addition, compared to manual adjustment, adjusting the patient's facial position through the coordinated use of multiple airbags can ensure the smoothness of the adjustment process, effectively avoiding injury to the patient due to improper manual operation by medical staff during the adjustment.

[0058] Because medical staff need to constantly monitor the patient's physical condition to ensure that the patient is not harmed by factors other than the surgery during the operation; therefore, the device in this embodiment can play a better auxiliary role in the operation, reducing the workload and work pressure of medical staff.

[0059] Therefore, the device body 100 in this embodiment can serve as a medical aid, effectively reducing the workload of medical staff.

[0060] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
