Description

Technical Field

[0001] The present invention relates to the field of medical devices, and more specifically, to an inflatable oral protective operating mask. Background Art

[0002] During oral treatment, a high-speed turbine drill is usually used, which will produce a large amount of droplets. The clinic is usually relatively closed. If the patient has an infectious disease, it is easy to cause contamination in the clinic space, which not only brings the risk of infection to medical staff, but also easily leads to infection of other medical personnel. The various departments of the hospital have also done enough protection in the process of admitting patients, but the oral department has special requirements for protection during the treatment process, which brings great difficulties to the treatment. This has also caused the oral department of many hospitals to be suspended for a long time, so that many patients cannot get treatment in time. At the same time, the economic pressure of the hospital has been greatly affected by the decline in the number of patients.

[0003] In order to solve the above problems, many dental departments require medical staff to wear protective clothing, including isolation gowns, shoe covers, goggles, face shields and other high-level protective equipment. At the same time, the consulting room is fully disinfected and ventilated for a specified period of time after each patient is seen. Although such measures can eliminate the dilemma of patients being unable to see a doctor to a certain extent, the efficiency cannot be improved due to the need for disinfection and ventilation between the previous and next patients. At the same time, the use of a large amount of materials in this process is also accompanied by the consumption of a large amount of manpower and material resources.

[0004] At present, there is a known splash-proof operation chamber designed for the stomatology department, which is formed by a transparent cover body, and a bracket and a universal wheel are installed under the operation chamber. During operation, the patient's head and upper body enter the cover body together, and the opening for the body to enter and exit is sealed by a sealing curtain. By opening an opening on the cover body, medical staff can put their hands into the cover body for operation. Among them, the transparent cover body is usually formed by welding using transparent materials such as acrylic. Although the above-mentioned operation chamber can reduce the risk of infection of medical staff to a certain extent, since the patient's head and upper body are both contained in the transparent cover, they are only sealed by a sealing curtain, and the shape characteristics of the upper body of the human body make it difficult to achieve strict sealing of the sealing curtain. At the same time, the patient will inevitably wear a top when seeing a doctor, which will further reduce the sealing effect. In addition, since the operation chamber is used by multiple patients, it also has the risk of secondary contamination. In order to eliminate cross-infection between patients, the operation chamber must be disinfected after the previous patient uses it, which cannot maximize the efficiency of diagnosis and treatment.

[0005] In order to solve the problems of difficult protection, easy cross infection, low diagnosis and treatment efficiency, and high consumption of manpower and material resources in the current oral diagnosis and treatment process, it is necessary to design a new protective device. Summary of the invention

[0006] In order to solve the problems of difficult protection, easy cross infection, low diagnosis and treatment efficiency, and high consumption of manpower and material resources in the current oral diagnosis and treatment process, the present invention designs an inflatable oral protection operation cover, and the specific technical solution adopted is:

[0007] An inflatable oral protection operation mask, comprising: more than two splicing surfaces, inflatable inflatable reinforcing ribs are arranged in each of the splicing surfaces and / or at the edges of the splicing surfaces, the mask body is surrounded by the more than two splicing surfaces, an opening is arranged on one of the splicing surfaces, and a sealing belt is arranged at the opening;

[0008] The cover body is provided with an operation port for medical staff to reach into the cover body for operation, an instrument inlet and outlet for medical instruments to enter and exit, a gas supply port and an exhaust port, and sealing members are installed at the operation port and the instrument inlet and outlet.

[0009] Furthermore, an opening inflatable reinforcement rib is provided around the opening in a closed or non-closed form on the joint surface provided with the opening.

[0010] The sealing strip is connected to the opening air-filled reinforcing rib via a transition zone.

[0011] The pneumatic reinforcing ribs arranged in the splicing surface or at the edge of the splicing surface are divided into at least one group in a manner that each group contains at least one pneumatic reinforcing rib, and only the pneumatic reinforcing ribs in the same group are connected to each other.

[0012] An instrument connection surface is arranged on the joint surface, and the gas supply port, the gas exhaust port and / or the instrument inlet and outlet are arranged on the instrument connection surface.

[0013] The sealing member comprises a supporting periphery, to which an upper sealing layer and a lower sealing layer are connected, wherein neither the upper sealing layer nor the lower sealing layer completely covers an opening defined by the supporting periphery, the upper sealing layer and the lower sealing layer have a stacking area, and the opening defined by the supporting periphery is completely covered by the upper sealing layer and the lower sealing layer.

[0014] The upper sealing layer includes an upper elastic member and an upper sealing sheet, wherein the upper sealing sheet connects the supporting periphery and the upper elastic member; the lower sealing layer includes a lower elastic member and a lower sealing sheet, wherein the lower sealing sheet connects the supporting periphery and the lower elastic member; the upper elastic member and the lower elastic member are staggered and arranged in parallel in the opening defined by the supporting periphery.

[0015] The opening is used to fit closely with the patient's neck, the sealing band is an elastic sealing band, and the transition zone is interference-fitted with the elastic sealing band.

[0016] The opening is used to be engaged with the patient's face, and a wearing rope is arranged around the opening.

[0017] The splicing surface is transparent.

[0018] The beneficial effects of the present invention are:

[0019] The inflatable oral protection operation cover disclosed by the present invention has all inflatable ribs not inflated when not in use, so the inflatable oral protection operation cover is in a collapsed state as a whole, which is convenient for storage. When in use, the inflatable ribs are inflated through the inflation and deflation valves, so that the inflatable oral protection operation cover is opened under the tension of the inflatable ribs. The patient can place the patient's head in the operation cover through the opening, and the opening is located at the patient's neck, and the patient's neck is sealed under the action of the elastic sealing belt. The patient can also wear the inflated oral protection operation cover on the face in a similar way to wearing a mask, so that the patient's mouth and nose can be placed in the operating space of the inflatable oral protection operation cover. Medical staff can perform treatment operations through the operating port. The oxygen supply device supplies oxygen to the operation cover through the oxygen input port, and the splashing droplets during the operation and the waste gas exhaled by the patient are discharged to the outside through the waste gas outlet, or are discharged to the outside after being sterilized. The inflatable oral protective operation mask disclosed in the present invention is small in size, easy to store and transport, has low manufacturing cost, can be provided to patients in a disposable form, avoids cross infection, and can maximize the hospital's diagnosis and treatment efficiency.

[0028] The inflatable oral protection operating mask provided by the present invention is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0029] like Figure 1 According to the first embodiment, the inflatable oral protection operation mask 100 comprises a transparent mask body, which comprises a mask surface 101, a bottom surface, a front interface 103 and a rear interface (not shown in the figure), and the mask surface 101, the bottom surface, the front interface 103 and the rear interface form a sealed operation space.

[0030] A plurality of transverse air-filled reinforcing ribs 115 are arranged on the cover surface 101. The cover surface 101 and the front interface 103 are connected at their junction by a front arc-shaped air-filled reinforcing rib 116. The cover surface 101 and the rear interface are connected at their junction by a rear arc-shaped air-filled reinforcing rib 117. The two junctions between the cover surface 101 and the bottom surface are respectively connected by a transverse air-filled reinforcing rib 115. The front interface 103 is provided with an opening 110 for the human head to enter and exit. The opening 110 is surrounded by an elastic sealing belt 111. The elastic sealing belt 111 is connected to an arc-shaped opening air-filled reinforcing rib 113 through a flexible transition zone 112. The shape of the opening air-filled reinforcing rib is the same as or similar to the shape of the opening, but this is not necessary. The transition zone 112 is fixedly connected to the open air-filled reinforcement rib 113, and the transition zone 112 and the elastic sealing belt 111 are interference-fitted, such as inserting the elastic sealing belt 111 into the hole formed by the transition zone at the end, similar to the form of an elastic cuff, so as to facilitate expansion and contraction in accordance with the elasticity of the elastic sealing belt 111. Those skilled in the art will know that there is no specific requirement for the form of the transition zone 112, as long as it can allow the elastic sealing belt 111 to freely expand and contract during the tensioning process to provide a suitable sealing effect. A plurality of longitudinal air-filled reinforcement ribs 114 are formed between the open air-filled reinforcement rib 113 and the front arc-shaped air-filled reinforcement rib 116 in the front interface 103. Those skilled in the art will understand that in order to further enhance the overall strength of the operating cover, a plurality of longitudinal air-filled reinforcement ribs can also be formed on the rear interface.

[0031] The transverse inflatable reinforcement ribs 115, the longitudinal inflatable reinforcement ribs 114, the open inflatable reinforcement ribs 113, the front arc-shaped inflatable reinforcement ribs 116, and the rear arc-shaped inflatable reinforcement ribs 117 are interconnected, and an air charging and discharging valve 140 is provided. Since all the reinforcement ribs are interconnected, the position where the air charging and discharging valve 140 is provided is not limited. In this embodiment, the air charging and discharging valve 140 is provided on one of the transverse inflatable reinforcement ribs at the intersection of the cover surface 101 and the bottom surface 102. More specifically, it is provided at a position close to the transverse inflatable reinforcement rib and close to the front interface 103, so as to facilitate the user to find it. Of course, the individual reinforcement ribs may also be disconnected, for example, all the inflatable reinforcement ribs are divided into several groups according to distance or area, and the same group is connected but different groups are not connected, and each group is provided with a separate air charging and discharging valve.

[0032] A plurality of operation ports 120 are provided on the mask surface 101, and the positions and number of the operation ports are preferably arranged to facilitate the operation of medical staff during treatment. For example, at least three operation ports 120 are provided, two for doctors to insert their hands during treatment, and the other for nurses to insert their hands during assistance. The number of the operation ports is preferably set to four, and they are provided on different sides of the vertical plane where the axis of the opening 110 is located, so that doctors can provide treatment at different positions. Those skilled in the art will appreciate that the number and position of the operation ports can be flexibly set according to actual needs.

[0033] like Figure 4 and 5 As shown, an oxygen inlet 130 and an exhaust gas outlet 131 are also provided on the mask surface 101, wherein the oxygen inlet 130 and the exhaust gas outlet 131 can be designed as a one-way valve.

[0034] The cover surface 101 is also provided with a plurality of instrument entrances and exits 121. Figure 4 ) and the back ( Figure 5 As shown in FIG. 1 , two are respectively provided. A person skilled in the art will appreciate that the number of instrument inlets and outlets can be flexibly set according to actual needs. The instrument inlets and outlets are usually more suitable for instruments that are connected to external equipment, such as high-speed turbine drills, and these instruments are connected to external equipment through a connecting pipeline during operation, and the instrument inlets and outlets are suitable for the entry and exit of the connecting pipeline.

[0035] Taking into account the gravity of these connecting pipelines, for pipelines extending from bottom to top, the instrument inlet and outlet 121 is set at a position close to the bottom of the mask 101 to avoid the influence of the weight of the pipeline itself on the operation mask. More preferably, the two ends of the mask 101 connected to the bottom are respectively provided with an instrument connection surface 1011 and 1012, and the bottom is connected through the instrument connection surface 1011 and 1012. The material of the instrument connection surface is formed by a hard material, or a flexible material but the thickness and toughness are thicker and tougher than the mask and the wearing surface. The instrument inlet and outlet 121, the oxygen input port 130, and the exhaust gas outlet 131 are all set on the instrument connection surface ( Figure 4 and Figure 5 Those skilled in the art will appreciate that the instrument connection surface is not necessary. For example, the instrument inlet and outlet 121 can be arranged on the bottom surface, specifically, at a position on the bottom surface close to the connection with the cover surface 101. Since the pipeline enters through the opening arranged on the bottom surface, the influence of the pipeline weight can also be avoided.

[0036] For suspended instruments, the pipelines are from top to bottom, so the instrument inlet and outlet 121 can be set at the top of the cover surface, and the instrument connection surface can be omitted.

[0037] like Figure 2 As shown, a seal 15 is provided at the operation port 120 and the instrument entrance 121. The seal includes a hard periphery 150. It should be understood that the hard periphery is not required, as long as it has a certain strength to play a supporting role. An upper sealing layer and a lower sealing layer are stacked on the hard periphery 150. The upper sealing layer includes an upper elastic member 151 and an upper sealing sheet 152. The upper elastic member 151 divides the hard periphery into two areas of different sizes. The upper sealing sheet 152 connects the hard periphery 150 to the upper sealing sheet 152. 50 and the upper elastic member 151 and cover the above-mentioned larger area; the lower sealing layer includes a lower elastic member 153 and a lower sealing sheet 154, wherein the lower elastic member 153 divides the hard periphery into two areas of unequal sizes, and the lower sealing sheet 154 connects the hard periphery 150 and the lower elastic member 153 and covers the above-mentioned larger area; the upper elastic member is arranged in parallel with the lower elastic member, and the upper sealing layer and the lower sealing layer are staggered so that the upper sealing sheet 152 and the lower sealing sheet 154 respectively block the exposed space of each other and have overlapping parts. The upper sealing sheet 152 and the upper elastic member 151 are connected by an interference fit, and the lower sealing sheet 154 and the lower elastic member 153 are connected by an interference fit. The sizes of the upper sealing layer and the lower sealing layer can be completely consistent or inconsistent, as long as they meet the staggered arrangement and can block the exposed space of each other. When the medical staff's hand passes through the operation port 120, such as Figure 3 As shown, the upper elastic member 151 is directed toward Figure 3 The left side shown in FIG. is squeezed, and the lower elastic member 153 is moved toward Figure 3 The right side is squeezed to expose an opening for the medical staff to insert their hands. At the same time, due to the elastic force of the elastic member, the upper and lower sealing sheets are driven to surround the arms of the medical staff to achieve sealing. Similarly, the sealing member at the instrument entrance and exit can also seal the instrument pipeline after the instrument is inserted. Those skilled in the art will understand that the sealing member is not limited to the above structure, and any suitable sealing structure can be used.

[0038] The cover surface 101, the bottom surface, the front interface 103 and the rear interface can all be made of flexible transparent materials. For embodiments that include an instrument connection surface, the portion other than the instrument connection surface is made of flexible transparent materials. The above-mentioned flexible transparent materials include but are not limited to transparent rubber, resin, transparent plastic, etc., to facilitate observation by medical staff during operation.

[0039] When the inflatable oral protection operation mask 100 is not in use, all the inflatable reinforcement ribs are not inflated, so the inflatable oral protection operation mask is in a collapsed state as a whole, which is convenient for storage. When in use, the inflatable reinforcement ribs are inflated through the inflation and deflation valves 140, so that under the tension of the inflatable reinforcement ribs, the inflatable oral protection operation mask is opened as shown in FIG. Figure 1 The state shown. The patient's head is placed in the operating cover through the opening 110, the opening is located at the patient's neck, and the patient's neck is sealed under the action of the elastic sealing belt 111. It should be noted that, thanks to the existence of the transition zone 112, the elastic sealing belt will not interfere with the normal function of the opening inflation reinforcement rib 113 during the tensioning and expansion process, that is, the existence of the transition zone 112 allows the patient's head to enter and exit the operating space of the inflatable oral protective operating cover 100, and the inflated opening inflation reinforcement rib 113 will not be squeezed or pulled. After the patient's head is positioned in the operating space of the inflatable oral protective operating cover 100, the oxygen supply device supplies oxygen to the operating cover through the oxygen inlet 130, and the splashing droplets during the operation and the waste gas exhaled by the patient are discharged to the outside through the waste gas outlet 131, or are discharged to the outside after being sterilized.

[0040] Figure 6 Another embodiment of the present invention is shown. According to this embodiment, an inflatable oral protection operation mask 200 is provided, including a transparent mask body, the mask body including a wearing surface 201 and a mask surface 202, and the wearing surface 201 and the mask surface 202 enclose a sealed operation space.

[0041] A plurality of three-dimensional inflatable reinforcing ribs 215 are provided on the cover surface 202, and the cover surface 202 is connected to the wearing surface 201 through a peripheral inflatable reinforcing rib 216. The shape of the peripheral inflatable reinforcing rib determines the shape of the entire wearing surface, which can be similar to the shape of the opening, or can be a quadrilateral, or other polygonal shape. Those skilled in the art can understand that different shapes can have an impact on the final shape of the device, and can be designed as needed.

[0042] An opening 210 is provided on the wearing surface, and the shape of the opening 210 is similar to the joint surface between the existing mask and the face. A wearing rope 260 is provided around the opening, so that the inflatable oral protection operation mask 200 can be worn on the patient's face in the same way as wearing a mask.

[0043] The opening is surrounded by a sealing strip 211, which can be realized by using existing technology used in masks. The sealing strip 211 is connected to an opening air-filled reinforcing rib 213 through a transition zone 212, and the shape of the opening air-filled reinforcing rib is the same or similar to the shape of the opening, but this is not necessary. The transition zone can be made of non-elastic material or elastic material, preferably elastic material, so that the patient's mouth has a surplus during the process of opening and closing, avoiding pulling on the opening air-filled reinforcing rib 213.

[0044] A plurality of diffusion inflatable reinforcement ribs 214 are arranged between the opening inflatable reinforcement ribs 213 and the peripheral inflatable reinforcement ribs 216 .

[0045] The three-dimensional inflatable reinforcement ribs 215, the peripheral inflatable reinforcement ribs 216, the diffuse inflatable reinforcement ribs 214 and the open inflatable reinforcement ribs 213 are interconnected and provided with an air charging and discharging valve 240. Since all the reinforcement ribs are interconnected, the location of the air charging and discharging valve 240 is not limited. In this embodiment, the air charging and discharging valve 240 is provided on the peripheral inflatable reinforcement ribs 216 to avoid its influence on the patient's face. It is also convenient for users to find it. Of course, the reinforcement ribs may not be connected, and may be divided into groups. There is at least one reinforcement rib in each group. The reinforcement ribs in the same group are connected but the reinforcement ribs in different groups are not connected. Each group is provided with a separate air charging and discharging valve.

[0046] Similar to the previous embodiment, a plurality of operation ports 220 may be provided on the mask surface 202 as required, and the position and number of the operation ports are suitable for the operation of medical staff during treatment. For example, at least three operation ports are provided, two for doctors to insert their hands during treatment, and the other for nurses to insert their hands during assistance. The number of the operation ports is preferably set to four, and they are provided on different sides of the vertical plane where the axis of the opening 210 is located, so that the doctor can provide treatment at different positions. Those skilled in the art will understand that the number and position of the operation ports can be flexibly set according to actual needs.

[0047] Similar to the first embodiment, an oxygen inlet 230 and an exhaust gas outlet 231 are also provided on the mask surface 202. The exhaust gas outlet is preferably provided at the opposite side of the mask surface to the oxygen inlet ( Figure 7 and 8 As shown), the oxygen inlet 230 and the exhaust gas outlet 231 can be designed with a one-way valve.

[0048] The cover surface 202 is also provided with a plurality of instrument entrances and exits 221. In this embodiment, two ( Figure 7 and 8 As shown). Those skilled in the art will appreciate that the number of instrument inlets and outlets can be flexibly set according to actual needs. The instrument inlets and outlets are usually more suitable for instruments that are connected to external devices, such as high-speed turbine drills, and these instruments are connected to external devices through a connecting pipeline during operation, and the instrument inlets and outlets are suitable for the entry and exit of the connecting pipeline.

[0049] Taking into account the gravity of these connecting pipelines, for pipelines extending from bottom to top, the instrument inlet and outlet 221 is set at the position of the mask surface 202 close to the wearing surface 201 to avoid the influence of the weight of the pipeline itself on the operation of the mask. More preferably, two instrument connection surfaces 2021 and 2022 are respectively set at the appropriate position where the mask surface 202 is connected to the wearing surface 201. The two instrument connection surfaces 2021 and 2022 are preferably arranged opposite to each other, and are connected to the wearing surface 201 through the instrument connection surfaces 2021 and 2022. The material of the instrument connection surface is formed by a hard material, or a flexible material is used, but the thickness and toughness are thicker and tougher than the mask surface and the wearing surface. The instrument inlet and outlet 221, the oxygen input port 230, and the exhaust gas outlet 231 are all set on the instrument connection surface.

[0050] Sealing members are also provided at the operation port 220 and the instrument port 221 , for example, the same sealing members as those in the first embodiment are used.

[0051] The mask surface 202 and the wearing surface 201 can both be made of flexible transparent materials. If the instrument connection surface is included, the part other than the instrument connection surface is made of flexible transparent materials. The above-mentioned flexible transparent materials include but are not limited to transparent rubber, resin, transparent plastic, etc., to facilitate observation by medical staff during operation.

[0052] When the inflatable oral protection operation mask 200 is not in use, all the inflatable reinforcement ribs are not inflated, so the inflatable oral protection operation mask is in a collapsed state as a whole, which is convenient for storage. When in use, the inflatable reinforcement ribs are inflated through the inflation and deflation valves 240, so that under the tension of the inflatable reinforcement ribs, the inflatable oral protection operation mask is opened as shown in FIG. Figure 6The patient wears the wearing rope 260 on the ear or face in a similar way to wearing a mask, so that the patient's mouth and nose can be placed in the operating space of the inflatable oral protection operating mask 200. Under the action of the sealing strip 211, the relative sealing of the operating space is achieved. The oxygen supply device supplies oxygen to the operating mask through the oxygen inlet 230, and the splashing droplets during the operation and the waste gas exhaled by the patient are discharged to the outside through the waste gas outlet 231, or are discharged to the outside after being sterilized.

[0053] The inflatable oral protective operation mask disclosed in the present invention is small in size, easy to store and transport, has low manufacturing cost, can be provided to patients in a disposable form, avoids cross infection, and can maximize the hospital's diagnosis and treatment efficiency.
