Description

Technical Field

[0001] The invention relates to medical protective equipment, in particular to a protective isolation device used for oral operation treatment. Background Art

[0002] During oral diagnosis and treatment, specialized equipment such as high-speed turbine handpieces and oral cleaners will produce water mist when working. When these devices rub the patient's teeth, the water mist produced can mix with the patient's saliva and / or blood to form an aerosol that diffuses from the open mouth to the surrounding air. In this way, a variety of pathogenic microorganisms (bacteria, viruses, fungi, etc.) accumulated in the mouth can be transmitted to others through aerosols, droplets or contact. Aerosol transmission is a relatively special transmission method in the process of oral diagnosis and treatment. After the operation is completed, there is still aerosols formed by blood, saliva and pathogens in the air, which makes prevention and control difficult.

[0003] During oral diagnosis and treatment, patients in the incubation period or who conceal their illness can easily transmit the virus to medical staff or other normal patients in the surrounding environment through aerosol transmission.

[0004] In the prior art, the examination or treatment of patients with oral diseases is performed in an exposed environment. Medical staff usually take protective measures such as wearing N95 masks or professional oral protective masks. Although N95 or professional oral protective masks can block most droplet transmission and aerosol transmission, they are expensive and frequently replaced, which will cause great waste. If the patient is infected with the new coronavirus, the high concentration of virus exhaled by the patient will not be able to isolate the virus. Surgical masks cannot be completely sealed due to edge leakage, and only block 60%-95% of aerosol transmission. Even if medical staff have personal safety protection equipment such as hats, masks, and protective glasses, they cannot prevent and control the aerosols still in the air after surgery after taking off the masks. Air filters and ventilation facilities with disinfection functions can reduce microorganisms in aerosols and block their long-distance transmission and transmission between clinics, but they are expensive. Summary of the invention

DETAILED DESCRIPTION

[0028] The protective isolation device 100 for oral operation treatment of the present invention is particularly suitable for oral treatment. When the patient's head is placed in a closed isolation space, it is convenient for doctors to perform various complex operations such as various tooth defect fillings, tooth preparation, periodontal cleaning and scaling for patients.

[0029] like Figure 1 As shown in FIG. 5 , the protective isolation device 100 is composed of a transparent protective isolation box 1 and a shoulder bracket 7.

[0030] 1. Transparent protective isolation box 1

[0031] The outer contour shape of the transparent protective isolation box 1 can be a cube, a cylinder or an ellipsoid. The present invention will be described in detail below using the cube shape as an example.

[0032] The transparent protective isolation box 1 of the present invention has a relatively large space inside. When it is put on the patient's head, the patient's head is placed in the transparent protective isolation box 1 in a suspended manner in the box (i.e., a relatively large space is left between the head and the box wall). In this way, during treatment, it is convenient for the patient's head to rotate left and right or up and down according to the prompts of the medical operator, and it is also convenient for the medical operator to flexibly operate the hand inserted into the box.

[0033] The transparent protective isolation box 1 is composed of a head frame 2 and box walls installed on six sides of the head frame 2. Figure 1 Taking the directions as an example, they are the front side 21 (i.e. the side that the patient's face faces when the patient's head enters the transparent protective isolation box 1), the left side 22, the right side 23, the top side 24, the bottom side 25 and the back side. The front side 21 is the interaction surface between the doctor and the patient, and must be made of a transparent hard material or a transparent soft film; the other four sides except the bottom side 25 can be transparent sides or non-transparent sides.

[0034] When the front face 21 is a hard transparent panel, the following installation method can be adopted: the hard transparent panel is installed on the side of the head frame 2 in a hinged manner, and a sealing ring (not shown) is provided around the edge of the head frame 2 side that matches the hard transparent panel. Or it is connected to the sealing ring around the edge of the head frame 2 side.

[0035] 1. Headstock 2

[0036] The head frame 2 is made of a light, rigid material with good strength, such as aluminum alloy, carbon fiber tube or composite plastic.

[0037] 2. Bottom 25 setting

[0038] The transparent protective isolation box 1 is provided with an entrance 3 for the patient's head to be inserted into, and the entrance 3 is arranged on the bottom surface 25 .

[0039] The bottom surface 25 has the following configurations:

[0040] The first is the basic design. Figure 1 As shown, the bottom surface 25 is a backing cloth 26 made of dense fiber cloth or thicker plastic cloth, the entrance 3 is arranged in the center of the backing cloth 26, and an elastic structure is arranged around the entrance 3. When the patient's head enters the box, the elastic structure is first opened by hand. After entering, the elastic structure returns to its original state and is tightened around the patient's neck, thereby closing the entrance 3.

[0041] The second is a further improvement. Figure 2 As shown, the bottom surface 25 is a hard bottom plate 27 made of a light material, and the four sides of the hard bottom plate 27 are sealed with the bottom frame of the head frame 2. The entrance 3 is set in the center of the hard bottom plate 27. A skirt 31 made of a flexible material and falling is provided at the entrance 3. A tether 32 is provided on the skirt 31 to tighten the skirt 31 around the patient's neck. When the patient's head enters the box through the entrance 3, the tether 32 can be tightened to tighten the skirt 31 and hoop it around the patient's neck, thereby closing the entrance 3 and isolating the inside of the transparent protective isolation box 1 from the outside of the box.

[0042] The third type is further improvement. Figure 3 As shown, the bottom surface 25 is composed of a part of a hard plate, that is, a hard side plate 28 made of a light material and having a narrow width is arranged on the side of the bottom surface 25 that is connected to the frame of the head frame 2. The hard side plate 28 can act as a reinforcing rib to stabilize the bottom frame of the head frame 2 and prevent deformation. An isolation layer 29 made of dense fiber cloth or plastic cloth is arranged around the inner side of the hard side plate 28, and the entrance 3 is arranged at the center of the isolation layer 29. A skirt 31 as in the second structure described above is arranged at the entrance 3. Similarly, a tether 32 is arranged on the skirt 31 to tighten the skirt 31 around the patient's neck.

[0043] The fourth is an improvement on the third structure. Figure 4 , 5 As shown in Figures 7 and 8, an air guide groove 4 is provided at the corner between the front surface 21 and the bottom surface 25 of the head frame 2. The cross-sectional shape of the air guide groove 4 is similar to the cross-sectional shape of a horn. The air guide groove 4 is in the shape of an elongated strip, and its length is slightly shorter than the length of the bottom side of the front surface 21. The opening of the air guide groove 4 points to the patient's face. The groove bottom of the air guide groove 4 is an arc-shaped surface. A plurality of through holes 41 or at least one through groove 42 that penetrate the groove plate of the air guide groove 4 are provided on the groove bottom. The periphery of the bottom surface 25 and the periphery of the back surface of the air guide groove 4 are sealed and connected to the bottom surface 25 and the front surface 21 respectively through a sealant or a sealing gasket. In this way, a narrow internal cavity 43 is formed between the back surface of the air guide groove 4 and the front surface 21 and the bottom surface 25 of the box body. The internal cavity 43 is connected to the box only through the through holes 41 or the through groove 42.

[0044] In this structural setting, the negative pressure exhaust port 52 is arranged at the right corner of the bottom surface 25 (the negative pressure exhaust port 52 is arranged on the hard side panel 28, and a hard interface that can be quickly connected to the negative pressure tube on the treatment dental chair is provided on the negative pressure exhaust port 52), and the negative pressure exhaust port 52 is located in the internal cavity 43, that is, there is no need to install a ventilation pipe between the negative pressure exhaust port 52 and the through hole 41 or the through groove 42 of the air guide groove 4 (the internal cavity 43 acts as a pipe). When the negative pressure pipe on the treatment dental chair is connected to the interface set on the negative pressure exhaust port 52, the exhaust gas in the box can be discharged from the transparent protective isolation box 1 through the through groove 42 or the through hole 41, the internal cavity 43, and the negative pressure exhaust port 52. In this structural setting, the trumpet opening angle of the air guide groove 4 is 60-80 degrees and is directed towards the patient's face (separated by a certain distance, the specific distance should not affect the doctor's treatment operations on the patient's oral cavity). When the negative pressure tube is suctioned, the air guide groove 4 can make the airflow velocity formed in the patient's mouth and nose area larger, thereby effectively and quickly drawing away the water mist, aerosol, etc. generated during the treatment operation.

[0045] In order to improve the suction efficiency of the negative pressure tube, the portion of the front side 21 in contact with the air guide groove 4 may be set as a hard plate. In this way, the internal cavity 42 is a cavity surrounded by the hard plate, which is beneficial to improving the suction effect.

[0046] 3. Operation port 51

[0047] At least two operation ports 51 are provided on the transparent protective isolation box 1 for the medical operator to insert his hands into the box for treatment. The present invention preferably has three operation ports 51, two of which are for the doctor to insert his hands into the box, and the other is for the assistant to insert his hands into the box. The surfaces and positions of the three operation ports 51 depend on whether the corresponding operator is accustomed to left-handed or right-handed operation.

[0048] The present invention arranges the three operating ports 51 in the following preferred manner:

[0049] The three operation ports 51 are respectively arranged on the left side 22, the right side 23 and the top surface 24. From the outside to the inside of the transparent protective isolation box 1, the operation port 51 on the left side 22 is located near 7 o'clock, the operation port 51 on the right side 23 is located near 4 o'clock, and the operation port 51 on the top surface 24 is located near 12 o'clock. The three operation ports 51 not only allow medical staff to have a certain degree of freedom in operation, but also meet the flexibility of the doctor's operation position in the 7 o'clock to 12 o'clock area and the flexibility of the assistant's operation position in the 2 o'clock to 4 o'clock area.

[0050] For a doctor who is accustomed to operating with his right hand and is located on the right side of the patient, the upper operation port 51 and the left operation port 51 are respectively used by the doctor's left hand and right hand to insert into the box for operation, and the right operation port 51 is used by the assistant's hand to insert into the box for operation.

[0051] A sleeve 6 with a length of 200 mm is provided on each operation port 51 .

[0052] 4. Air guide port 53

[0053] Two air ducts 53 are provided on the top of the transparent protective isolation box 1 for supplying fresh air into the box. A one-way protective filter membrane opening from outside to inside is provided in the air duct 53 to prevent the air in the box from leaking out through the air duct 53 .

[0054] 5. Negative pressure exhaust port 52

[0055] The inner diameter of the negative pressure suction port 52 is 15mm-40mm, and the negative pressure suction port 52 is used to discharge the air in the box and send it to the sterilization and filtering device.

[0056] 6. Saliva suction tube socket 54

[0057] The saliva suction tube socket 54 is provided with a sleeve 6 with a length of 50 mm, and the end of the sleeve 6 is provided with an elastic opening for tightening the saliva suction tube. The present invention preferably sets the saliva suction tube socket 54 on the right side 23 (which is beneficial for doctors with right-handed operation habits, and the assistant is located on the left side of the patient to operate).

[0058] 7. Delivery port 55

[0059] A delivery port 55 is provided on the left side 22, the right side 23 or the top side 24 for the assistant operator to deliver medical instruments or therapeutic materials into the transparent protective isolation box 1. The area of ​​the delivery port 55 is smaller than 1 / 2 of the area of ​​the corresponding surface. The position of the delivery port 55 depends on the hand habits of the medical operator.

[0060] The present invention sets the delivery port 55 on the right side 23. For sealing, a cover with a single-layer sealing structure or a double-layer sealing structure is provided on the delivery port 55 to close or open the delivery port 55, the inner side edge of the cover is sealed and connected to the transparent plate or transparent film on the corresponding surface, and the outer edge of the cover is connected to the delivery port 55 by Velcro, a zipper (including a medical zipper) or a combination of the two.

[0061] 8. Protective isolation pullover 33

[0062] A protective isolation pullover 33 that can be worn on the patient is connected to the lower edge of the skirt 31 through a snap or zipper connection structure (the protective isolation pullover 33 can also be an integrated structure with the skirt 31). The protective isolation pullover 33 is used to prevent the treatment materials from dripping onto the patient during treatment.

[0063] The soft protective isolation pullover 33 has an opening on the back, and ties are provided on both sides of the opening to facilitate closing the opening.

[0064] 9. Hard transparent panels and soft transparent films

[0065] The hard transparent panel has a transmittance of visible light with a wavelength of 400 to 800 nm. 80％ The hard transparent mask with good light transmittance can ensure the doctor's clear clinical operation field of vision.

[0066] The soft transparent film is a PET, PI, PVC, PE or TPU transparent film.

[0067] 10. Sleeve 6

[0068] The sleeves 6 on each operation port 51 and the saliva suction tube insertion port 54 are all made of a soft medical protection isolation material. An elastic structure is provided at the end of each sleeve 6, which can effectively block the leakage of harmful substances in the transparent protection isolation box 1 when the medical operator operates.

[0069] 2. Shoulder Bracket 7

[0070] like Figure 1 -4 and Figure 6 As shown, the shoulder support 7 is used to stably wear the transparent protective isolation box 1 on the patient's head.

[0071] There are two shoulder supports 7, one for the left frame and the other for the right frame. Each shoulder support 7 consists of an upper fixing 71, an elastic connecting rod 72 and a lower fixing 73. Its appearance is an inverted "Y" shape. The upper fixing 71 is fixed to the bottom edge of the head frame 2, and the elastic connecting rod 72 is connected between the upper fixing 71 and the lower fixing 73. The lower fixing 73 is a "Y"-shaped fork, which can be set to a structure with an adjustable fork opening size, that is, it is suitable for patients with different shoulder widths.

[0072] 1. Upper firmware 71 and lower firmware 73

[0073] In order to accommodate patients with different neck lengths, the upper fixture 71 and the lower fixture 73 may adopt a telescopic adjustment structure. For example, the upper fixture 71 or the lower fixture 73 may adopt a double-tube sleeve type telescopic fastening structure or other conventional telescopic mechanical connection structure.

[0074] To facilitate installation, the connection structures between the upper fastener 71 and the head frame 2, between the upper fastener 71 and the elastic connecting rod 72, and between the elastic connecting rod 72 and the lower fastener 73 can all be set as quick-connect connection structures, such as setting studs on the bottom edge of the head frame 2, and using a hand-screw nut sleeved on the upper fastener 71 to manually fix the upper fastener 71 to the head frame 2, or a male and female buckle snap-on connection structure, etc.

[0075] 2. Elastic connecting rod 72

[0076] The function of the elastic connecting rod 72 is: when the transparent protective isolation box 1 is not subjected to external forces, the transparent protective isolation box 1 is worn on the patient's head in a vertical state. When the medical operator inserts his hand into the transparent protective isolation box 1 to perform treatment operations, the transparent protective isolation box 1 is allowed to change in the direction of the external force it is subjected to in sync with the action of the medical operator as the medical operator's hand moves, that is, the elastic connecting rod 72 will bend and deform appropriately. When the external force applied to the transparent protective isolation box 1 by the medical operator is released, the elastic connecting rod 72 returns to its original vertical state under the action of the elastic restoring force of the elastic connecting rod 72, that is, the transparent protective isolation box 1 returns to its original vertical state (of course, the original state of the transparent protective isolation box 1 can also be set to a state slightly tilted backward relative to the human body according to medical needs).

[0077] The elastic connecting rod 72 of the present invention is composed of a lower end connecting piece 722 and a coil spring 723 connected between the upper end connecting piece 721 and the lower end connecting piece 722 (of course, an elastic connecting plate composed of multiple elastic steel sheets stacked together can also be used), which can be commercially available or customized.

[0078] The length of the elastic connecting rod 72 depends on the allowable range of change of the transparent protective isolation box 1. That is, when the allowable range of change is large, the spiral spring 723 part of the elastic connecting rod 72 can be longer, otherwise, the spiral spring 723 part of the elastic connecting rod 72 will be shorter.

[0079] 3. Fastening belt

[0080] In order to fix the shoulder support 7 well on the corresponding shoulder, a quick-release bandage is provided on the lower fixture 73 of the left frame and the right frame, which can be used to fix the lower fixture 73 around the patient's armpit or chest. The quick-release bandage can be a belt with Velcro, a belt with snaps, or a belt with a belt buckle.

[0081] In order to prevent the lower fixture 73 from getting stuck on the patient's shoulder and causing the patient to feel uncomfortable, a soft pad can be provided on the area of ​​the lower fixture 73 that contacts the shoulder.

[0082] 3. Usage

[0083] The method of using the protective isolation device 100 for oral operation treatment of the present invention is as follows:

[0084] 1. Before the patient sees the doctor, the assistant helps the patient to put the head into the soft protective isolation jacket 33 through the back opening, so that the patient's head is located in the center of the transparent protective isolation box 1, and the hard transparent panel is located in front of the patient's face. The shoulder bracket 7 is placed, the bracket height is adjusted and fixed, and the soft protective isolation jacket 33 is clamped around the patient's neck using the neck-shrinking tether 32 to form a space isolated from the outside in the transparent protective isolation box 1, and the tether is tied to close the back opening of the soft protective isolation jacket 33;

[0085] 2. During diagnosis and treatment, the patient lies on his back on the dental chair, and the external negative pressure suction tube is connected to the negative pressure exhaust port 52. The doctor puts on gloves and extends his left and right hands into the transparent protective isolation box 1 from the upper operation port 51 and the left operation port 51 respectively. The wrists of the medical staff are tightly clamped by the elastic mouth. At this time, the transparent protective isolation box 1 is relatively closed, and the patient's oral operation is performed through the hard transparent panel. The sleeve-type operation port 51 can facilitate the doctor's flexible operation and avoid contamination of the doctor's easily contaminated area-the forearm. The assistant extends the external saliva suction tube into the patient's mouth from the saliva suction tube socket 54, cooperates with the doctor's operation, and sucks away water and saliva in time. The assistant's right hand can be extended from the right operation port 51 into the transparent protective isolation box 1 to cooperate with the doctor's operation. During the operation and treatment, the medical staff can observe the patient's head, face, and oral cavity through the hard transparent panel and the transparent films on the surrounding walls of the transparent protective isolation box 1;

[0086] 3. When doctors use high-speed mobile phones, ultrasonic dental cleaning machines, etc. to operate on patients, turning on the external negative pressure switch can immediately absorb the droplets and aerosols generated during treatment. The closed operating space also blocks splashes during diagnosis and treatment, and prevents droplets, aerosols and splashes from entering the air of the clinic or the bodies of medical staff and normal patients. Continuous negative pressure suction combined with trumpet-shaped air guide grooves can avoid the formation of aerosols on the transparent mask to ensure a good operating field of vision. The two air guide ports 53 set on the transparent protective isolation box 1 provide fresh air from the outside to the box. The droplets and aerosols in the transparent protective isolation box 1 will not be discharged from the two air guide ports 53 under the blocking of the one-way medical protective filter membrane;

[0087] 4. After the diagnosis and treatment, continue to use negative pressure suction for 30-60 seconds to completely remove the droplets and aerosols remaining in the closed space of the transparent protective isolation box 1;

[0088] 5. Finally, the assistant helps to untie the necking tether 32 on the back of the soft protective isolation pullover 33 and the tether of the opening, and removes the protective isolation device 100 for oral operation treatment from the patient.
