Description

Technical Field

[0001] The invention relates to the technical field of oral bronchoscope intubation, and in particular to a bronchoscope intubation assistant suitable for high-flow oxygen inhalation. Background Art

[0002] Difficult airway refers to a clinical situation in which a professionally trained anesthesiologist with more than five years of clinical anesthesia experience has difficulty with mask ventilation or intubation, or both. However, airway assessment in clinical work is often very subjective, and even professional clinicians find it difficult to accurately predict which cases are challenging. Studies have shown that more than 90% of difficult endotracheal intubations are unexpected. There are more than a hundred tools and methods for difficult airway, which are divided into tools and methods for handling non-emergency airway and emergency airway. The purpose of handling non-emergency airway is non-invasive, while the purpose of handling emergency airway is to save lives. We follow the principle of non-invasive first and then invasive to establish the airway. Among them, non-emergency non-invasive tools and methods mainly include laryngoscopes, transtracheal tubes, and supraglottic airway tools (SAD). Among them, transoral fiberoptic bronchoscope-guided endotracheal intubation is one of the best intubation methods for handling difficult airways that are difficult to predict. However, for unpredictable difficult airways, in patients under deep anesthesia or anesthesia, the tongue root and pharynx are displaced posteriorly to the posterior pharyngeal wall, the gap between the oropharynx and hypopharynx is small, the fiber optic cable of the fiberoptic bronchoscope is soft and difficult to operate, and the tip of the fiberoptic bronchoscope is difficult to maintain in the midline position when entering the pharynx and larynx. Therefore, it is almost impossible to achieve oral intubation with a fiberoptic bronchoscope without the aid of any auxiliary tools.

[0003] At present, there are intubation-type laryngeal masks, ovassapian airways, Pentax-AWS lenses, Lee fiberoptic bronchoscope intubation airways, and tracheal intubation is performed under the guidance of fiberoptic bronchoscopes. However, the intubation-type laryngeal masks are expensive and not suitable for promotion and application in clinical work; while the ovassapian airway, Pentax-AWS lenses, and Lee fiberoptic bronchoscope intubation airways are designed to open the oropharyngeal space and introduce the fiberscope in the midline of the oropharynx. Despite the use of these airways, partial or complete obstruction of the fiberoptic field of view is common, and the huge epiglottis can easily block the glottis, making it difficult for the fiberoptic bronchoscope to pass through, and the midline of the airway is difficult to fix and block the field of view. And because fiberoptic bronchoscope intubation is often used for difficult airways, as the intubation time increases, the patient's blood oxygen gradually decreases, making it difficult to continue intubation. Therefore, a transoral fiberoptic bronchoscope-guided tracheal intubation aid is designed.

[0004] The patent with application number 2021104577272 discloses an intubation aid to solve the above problems, and the technical solution has also been produced, sold and applied in clinical practice. However, the product of the above patent is made of medical resin, but this material is hard, which causes the intubation aid to be very uncomfortable when inserted into the patient's body because of stretching the throat, and even causes tissue scratches. The size of the throat of different people is not necessarily the same, and the intubation aid disclosed in the above patent is an unclosed C-shaped groove structure, which can reduce the spacing at the notch by force deformation at the notch, so as to be suitable for different people. However, due to the slot structure, when the intubation aid is inserted into the patient, the patient's tissues and organs corresponding to the slots will be embedded in the slots, causing discomfort or even pain, and the organ tissues will be scratched due to the relative movement caused by the insertion of the intubation aid. In addition, after the intubation aid is inserted, when the bronchoscope or cannula is inserted, the organ tissues embedded in the slots will cause the cross-section of the intubation channel to be reduced, making it inconvenient to insert the bronchoscope or cannula, and the inserted bronchoscope or cannula will also move relative to the organ tissues embedded in the slots, causing scratches to the organ tissues embedded in the slots.

[0005] If the medical resin is directly replaced with a flexible material, the intubation aid will become soft and will not cause damage to the patient's organs and tissues. However, the soft material will make the intubation aid inconvenient to insert into the patient's body due to its low rigidity. Moreover, after being inserted into the patient's body, the intubation aid will be directly deformed due to the pressure of the organs and tissues in the throat, which will cause the intubation channel to deform and there will not be enough channel space to insert the bronchoscope or intubation tube.

[0006] Therefore, it is now necessary to develop an intubation aid that can facilitate the insertion of a bronchoscope or intubation and avoid causing damage to the patient's organ tissue. Summary of the invention

[0007] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a bronchoscope intubation aid suitable for high-flow oxygen inhalation. By connecting the structure of the diaphragm, the arc-shaped groove body can be closed while retaining the deformable space of the arc-shaped groove body, thereby ensuring that the intubation aid can be inserted into the patient's body. The intubation aid can be compliantly deformed due to the irregular structure of the body, and a closed space can be formed in the arc-shaped groove body to prevent the softer tissue in the patient's body from extending into the arc-shaped groove body from the groove, thereby avoiding the hidden danger of scratching the tissue when the intubation aid and the intubation tube are inserted.

The longitudinal ribs and the transverse ribs are connected and fixed, and the outer sides of the longitudinal ribs and the transverse ribs are covered with a filling layer. The portion of the filling layer corresponding to the inner cavity of the arc-shaped groove body is flush with the inner wall of the groove-shaped skeleton. The portion of the filling layer corresponding to the outer side wall of the arc-shaped groove body covers the outer wall of the groove-shaped skeleton and extends to contact with the limiting flange. The connecting diaphragm is connected to the filling layer covering the outer edge of the groove of the arc-shaped groove body. The limiting flange, the groove-shaped skeleton, the longitudinal ribs and the transverse ribs are all made of medical polymer resin, and the connecting diaphragm and the filling layer are all made of medical TPE.

[0010] A further improvement of the present invention is that the longitudinal ribs of the arc-shaped trough body respectively extend to one end of the extension piece away from the arc-shaped trough body, the transverse ribs corresponding to the longitudinal ribs extending to the extension piece are evenly distributed along the extension direction of the extension piece, and the two ends of the transverse ribs respectively extend to the corresponding sides of the extension piece, and the filling layer on the outside of the longitudinal ribs and transverse ribs coated at the extension piece position is flush with the filling layer on the outside of the longitudinal ribs and transverse ribs coated at the arc-shaped trough body position.

[0011] A further improvement of the present invention is that the ends of the longitudinal ribs extending to the extension piece away from the arc-shaped groove body are respectively provided with enlarged heads, the enlarged heads are located at the positions where the epiglottis raises its head, and the material of the enlarged heads is medical polymer resin.

[0012] A further improvement of the present invention is that a transverse cavity sac is provided on the curved outer side of the end of the extension piece away from the arc-shaped trough body corresponding to the position of the epiglottis raising head, and the transverse cavity sac is located in the filling layer. The transverse cavity sac makes the side of the end of the extension piece away from the arc-shaped trough body and facing away from the epiglottis raising head flush with the part of the extension piece corresponding to the inner cavity of the arc-shaped trough body.

[0013] A further improvement of the present invention is that a reinforcing plate is fixed to the bottom portion of the arc-shaped trough body, located on the side of the transverse rib facing away from the longitudinal rib, and the reinforcing plate extends along the arc-shaped trough body to the extension piece, and the reinforcing plate is respectively connected and fixed to the transverse ribs passed through, and the material of the reinforcing plate is medical polymer resin.

[0014] A further improvement of the present invention is that the two side edges of the reinforcing plate are respectively rolled up to form curled edges, and the filling layer is coated on the curled edge surface to form longitudinal guide bars of the trough body and the extension sheet protruding from the arc-shaped trough body, and the longitudinal guide bars are symmetrically located on both sides of the trough bottom of the arc-shaped trough body.

[0015] A further improvement of the present invention is that the groove-shaped skeleton is provided with extended protrusions symmetrically inwardly at the positions corresponding to the grooves, the spacing between the extended protrusions is smaller than the spacing of the grooves, the end face of the limiting flange corresponding to the groove is flush with the extended protrusions, and the material of the extended protrusions is medical polymer resin.

[0016] A further improvement of the present invention is that a plurality of lateral support sheets are connected between the notches of the arc-shaped groove body and on the side of the connecting diaphragm facing the arc-shaped groove body, and the lateral support sheets are distributed in sequence along the extension direction of the arc-shaped groove body. The lateral pre-compression force provided by the lateral support sheets tensions the connecting diaphragm laterally, and the elastic restoring force of the connecting diaphragm after being stretched is balanced with the lateral force of the lateral support sheets. The material of the lateral support sheets is a medical polymer resin.

[0017] A further improvement of the present invention is that the outer edge of the slot of the arc-shaped slot body is provided with a connecting slot along the extension direction of the slot, and the two side edges of the lateral support piece are respectively fixedly connected to the connecting slots on the corresponding sides.

[0018] The beneficial effects of the present invention are: First, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention can form a closed arc-shaped groove body and retain a deformable space in the arc-shaped groove body through the structure of the connected diaphragm, thereby ensuring that the intubation aid can be conveniently inserted into the patient's body. The intubation aid can be deformed compliantly due to the irregular structure of the body, and a closed space can be formed in the arc-shaped groove body to prevent the softer tissue in the patient's body from extending into the arc-shaped groove body from the notch, thereby avoiding the hidden danger of scratching the tissue when the intubation aid and the intubation tube are inserted. The high-flow oxygen inhalation tube can be used to provide high-flow oxygen inhalation to the patient.

[0019] Second, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention can maintain the overall shape of the arc-shaped trough body through the effects of longitudinal ribs, transverse ribs and the filling layer. The local structure will be deformed due to the restriction of some irregular structures in the body. The filling layer is located on the surface of the intubation aid inserted into the patient's body, and the material of the filling layer is relatively soft. It will be deformed due to contact with the raised parts of the patient's organ tissue, so that the intubation aid can not only play the role of assisting intubation, but also reduce or even eliminate the sense of oppression and discomfort caused to the tissues in the patient's body.

[0020] Third, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention is extended or distributed to the extension piece by longitudinal ribs and transverse ribs, so that the extension piece and the arc-shaped groove body form an integral structure as a whole, and the deformation performance of the extension piece and the arc-shaped groove body can also be consistent. Therefore, when the intubation aid is deformed due to being restricted by certain tissues in the patient's body, the overall structure of the intubation aid can still be maintained as much as possible, thereby facilitating the intubation operation.

[0021] Fourthly, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention can make the strength of the epiglottis lifting head relatively greater by enlarging the structural setting of the head. In addition, the epiglottis lifting head is formed by bending, which makes it easier to lift the epiglottis so as to complete the intubation operation.

[0022] Fifth, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention has a strong strength of the epiglottic lifting head, so that during the process of inserting the intubation aid into the patient's body, the tissue structure at the corresponding position of the patient would be compressed due to the additional structure of the epiglottic lifting head, causing discomfort. However, through the structure of the transverse hollow bag, the end of the extension piece can be made softer relative to the other side of the epiglottic lifting head, so that it is convenient to directly compress the hollow bag, thereby reducing or even eliminating the pressure of the epiglottic lifting head on the tissue and organs at the corresponding position of the patient; and when the intubation aid is inserted into the patient's body to the corresponding position, the consistency of the overall extension piece and the bottom structure of the arc-shaped groove body can be maintained through the action of the hollow bag, so that the intubation tube is convenient to be inserted from the corresponding angle along the extension piece after passing through the arc-shaped groove body.

[0023] Sixth, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention increases the strength of the corresponding parts of the bottom of the arc-shaped groove body and the extension piece through the role of the reinforcing plate, so that the deformation of the arc-shaped groove body is concentrated on the groove walls on both sides of the groove body, thereby making the space of the inner cavity in the arc-shaped groove body sufficient to ensure the smooth insertion of the intubation tube.

[0024] Seventh, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention has a longitudinal guide strip structure formed by the curling, which facilitates the guidance of the insertion of the cannula and ensures the position accuracy of the cannula after insertion; and the curling structure itself is also elastic, so it can be suitable for cannulas of different calibers.

[0025] Eighth, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention has a smaller spacing between the slots of the slotted frames through the effect of extending the protrusions. The slotted frames located at the limiting flange position are just located at the patient's tooth occlusion area, which can not only prevent the teeth from sinking into the slots due to the large spacing between the slots, but also has sufficient strength to effectively ensure the structural strength of the aid and the stability of the overall shape.

[0026] Ninth, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention balances the forces of the lateral support sheets and the connecting diaphragm, thereby relatively reducing the deformation sensitivity between the notches of the arc-shaped groove body, which is beneficial to maintaining the structure of the inner cavity and ensuring smooth intubation.

[0027] Tenth, the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention, through the structure of the lateral support sheet A, makes the deformation sensitivity of the arc-shaped groove body located at the connection between the groove frame and the longitudinal ribs, transverse ribs and the filling layer part consistent.

[0028] Eleventh, in the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention, both ends of the connecting slot are respectively closed by limiting flanges and corresponding filling layers to prevent the lateral support sheets from sliding out from both ends of the connecting slot.

[0029] Twelfth, in the bronchoscope intubation aid suitable for high-flow oxygen inhalation of the present invention, the connecting diaphragm extends to the side of the limiting flange facing away from the arc-shaped groove body, thereby ensuring the consistency of the deformation sensitivity at the notch of the entire arc-shaped groove body.

[0035] By connecting the structure of the diaphragm 7, the arc-shaped groove body 1 can be closed while retaining a deformable space in the arc-shaped groove body 1, thereby ensuring that the intubation aid can be easily inserted into the patient's body. The intubation aid can be deformed compliantly due to the irregular structure of the body, and a closed space can be formed in the arc-shaped groove body 1 to prevent the softer tissue in the patient's body from extending into the arc-shaped groove body 1 from the notch 6, thereby avoiding the hidden danger of scratching the tissue when the intubation aid and the intubation tube are inserted. The high-flow oxygen tube 8 can be used to provide high-flow oxygen to the patient.

[0036] The arcuate trough body 1 comprises a trough frame 9 arranged at the end where the limiting flange 3 is located, the limiting flange 3 is arranged at the end of the trough frame 9, the arcuate trough body 1 is located at the end of the trough frame 9 which is opposite to the limiting flange 3, and a plurality of transverse ribs 11 are uniformly arranged in sequence along the extension direction of the arcuate trough body 1, and a plurality of longitudinal ribs 10 are uniformly distributed on the outer edge of the end of the trough frame 9 which is opposite to the limiting flange 3, and the longitudinal ribs 10 are respectively extended along the extension direction of the arcuate trough body 1, and the longitudinal ribs 10 are respectively connected and fixed to the outer edges of the transverse ribs 11 when passing through the transverse ribs 11, and the longitudinal ribs The outer side of 10 and the transverse ribs 11 are coated with a filling layer 12, and the portion of the filling layer 12 corresponding to the inner cavity 5 of the arc-shaped trough body 1 is flush with the inner wall of the trough-shaped skeleton 9, and the portion of the filling layer 12 corresponding to the outer side wall of the arc-shaped trough body 1 covers the outer wall of the trough-shaped skeleton 9 and extends to contact with the limiting flange 3, and the connecting diaphragm 7 is connected to the filling layer 12 coated on the outer edge of the notch 6 of the arc-shaped trough body 1, and the materials of the limiting flange 3, the trough-shaped skeleton 9, the longitudinal ribs 10 and the transverse ribs 11 are all medical polymer resins, and the materials of the connecting diaphragm 7 and the filling layer 12 are all medical TPE.

[0037] Through the action of the longitudinal ribs 10, the transverse ribs 11 and the filling layer 12, the arc-shaped trough body 1 can maintain the overall shape of the structure, while the local structure will be deformed due to the restriction of some irregular structures in the body. The filling layer 12 is located on the surface of the intubation aid inserted into the patient's body, and the material of the filling layer 12 is relatively soft. It will be deformed due to contact with the raised parts of the patient's organ tissue, so that the intubation aid can not only play the role of assisting intubation, but also reduce or even eliminate the sense of pressure and discomfort caused to the tissues in the patient's body.

[0038] The longitudinal ribs 10 of the arcuate trough body 1 respectively extend to one end of the extension piece 2 away from the arcuate trough body 1, and the transverse ribs 11 corresponding to the part of the longitudinal ribs 10 extending to the extension piece 2 are evenly distributed along the extension direction of the extension piece 2, and the two ends of the transverse ribs 11 respectively extend to the corresponding sides of the extension piece 2, and the filling layer 12 on the outside of the longitudinal ribs 10 and the transverse ribs 11 coated at the position of the extension piece 2 is flush with the filling layer 12 on the outside of the longitudinal ribs 10 and the transverse ribs 11 coated at the position of the arcuate trough body 1.

[0039] The longitudinal ribs 10 and the transverse ribs 11 are extended or distributed to the extension piece 2, so that the extension piece 2 and the arcuate groove body 1 form an integral structure as a whole, and the deformation performance of the extension piece 2 and the arcuate groove body 1 can also be consistent. Therefore, when the intubation aid is deformed due to being restricted by certain tissues in the patient's body, the overall structure of the intubation aid can still be maintained as much as possible, thereby facilitating the intubation operation.

[0040] An enlarged head 13 is provided at one end of the longitudinal rib 10 extending to the extension piece 2 away from the arc-shaped groove body 1. The enlarged head 13 is located at the position where the epiglottis lifts up the head 4. The material of the enlarged head 13 is a medical polymer resin.

[0041] By enlarging the structure of the head 13, the strength of the epiglottis lifting head 4 can be made relatively greater. In addition, the epiglottis lifting head 4 is formed by bending, which makes it easier to lift the epiglottis so as to complete the intubation operation.

[0042] A transverse cavity sac 14 is also provided on the curved outer side of the extension piece 2 at one end away from the arc-shaped groove body 1, corresponding to the position of the epiglottis raising head 4. The transverse cavity sac 14 is located in the filling layer 12. The transverse cavity sac 14 makes the end of the extension piece 2 away from the arc-shaped groove body 1 and the side facing away from the epiglottis raising head 4 flush with the part of the extension piece 2 corresponding to the inner cavity 5 of the arc-shaped groove body 1.

[0043] Due to the strong strength of the epiglottic lifting head 4, when the intubation aid is inserted into the patient's body, the tissue structure at the corresponding position of the patient would be compressed due to the additional structure of the epiglottic lifting head 4, causing discomfort. However, the structure of the transverse hollow sac 14 can make the end of the extension piece 2 softer than the other side of the epiglottic lifting head 4, thereby facilitating direct compression of the hollow sac 14, thereby reducing or even eliminating the compression of the epiglottic lifting head 4 on the tissue and organs at the corresponding position of the patient; and when the intubation aid is inserted into the patient's body to the corresponding position, the hollow sac 14 can maintain the consistency of the overall extension piece 2 and the bottom structure of the arc-shaped slot body 1, so that the intubation tube can be inserted from the corresponding angle along the extension piece 2 after passing through the arc-shaped slot body 1.

[0044] A reinforcing plate 15 is fixed to the bottom of the arc-shaped trough body 1, on the side of the transverse rib 11 facing away from the longitudinal rib 10. The reinforcing plate 15 extends along the arc-shaped trough body 1 to the extension piece 2. The reinforcing plate 15 is respectively connected and fixed to the transverse rib 11 passed through. The reinforcing plate 15 is made of medical polymer resin.

[0045] Through the action of the reinforcing plate 15, the strength of the corresponding parts of the bottom of the arcuate groove body 1 and the extension piece 2 is increased, so that the deformation of the arcuate groove body 1 is concentrated on the groove walls on both sides of the groove body, and the space of the inner cavity 5 in the arcuate groove body 1 is sufficient to ensure the smooth insertion of the cannula.

[0046] The two side edges of the reinforcing plate 15 are respectively rolled up to form curling edges 16, and the filling layer 12 is coated on the surface of the curling edges 16 to form longitudinal guide bars 17 protruding from the arc-shaped trough body 1 and the extension sheet 2. The longitudinal guide bars 17 are symmetrically located on both sides of the bottom of the arc-shaped trough body 1.

[0047] The longitudinal guide strip 17 structure formed by the curling edge 16 facilitates the guidance of the insertion of the cannula, thereby ensuring the position accuracy of the cannula after insertion; and the curling edge 16 structure itself is also elastic, so it can be suitable for cannulas of different calibers.

[0048] The groove-shaped skeleton 9 is provided with extended protrusions 21 symmetrically arranged inwardly at the position corresponding to the notch 6, the spacing between the extended protrusions 21 is smaller than the spacing between the notches 6, the end face of the limiting flange 3 corresponding to the notch 6 is flush with the extended protrusions 21, and the material of the extended protrusions 21 is medical polymer resin.

[0049] By extending the protrusion 21, the spacing between the slots 6 between the slot-shaped skeletons 9 is made smaller, and the slot-shaped skeleton 9 located at the position of the limiting flange 3 is just located at the patient's tooth occlusion position, which not only prevents the teeth from sinking into the slots 6 due to the large spacing between the slots 6, but also has sufficient strength to effectively ensure the structural strength of the auxiliary device and the stability of the overall shape.

[0050] The connecting slot 20 passes through the extending protrusion 21 and extends to the limiting flange 3 .

[0051] The extending direction of the groove-shaped frame 9 is the bending tangent direction of one end of the arc-shaped groove body 1 provided with the groove-shaped frame 9 .

[0052] A plurality of lateral support sheets 19 are connected between the notches 6 of the arc-shaped trough body 1 and on the side of the connecting diaphragm 7 facing the arc-shaped trough body 1. The lateral support sheets 19 are sequentially distributed along the extension direction of the arc-shaped trough body 1. The lateral pre-compression force provided by the lateral support sheets 19 tensions the connecting diaphragm 7 laterally. The elastic restoring force of the connecting diaphragm 7 after being stretched is balanced with the lateral force of the lateral support sheets 19. The material of the lateral support sheets 19 is a medical polymer resin.

[0053] By balancing the forces of the lateral support sheet 19 and the connecting diaphragm 17, the deformation sensitivity between the notches 6 of the arc-shaped slot body 1 is relatively weakened, which is beneficial to maintaining the structure of the inner cavity 5 and ensuring smooth intubation.

[0054] A connecting slot 20 is provided at the outer edge of the slot 6 of the arc-shaped slot body 1 and along the extending direction of the slot 6 , and both side edges of the lateral support piece 19 are fixedly connected to the connecting slot 20 on the corresponding side respectively.

[0055] The structure of the connecting slot 20 facilitates the connection and fixation of the lateral support sheet 19 .

[0056] The one of the lateral support pieces 19 closest to one end of the limiting flange 3 is a lateral support piece A19', which extends from the limiting flange 3 to the side of the groove-shaped frame 9 facing away from the limiting flange 3, and the position of the connection between the groove-shaped frame 9 and the longitudinal rib 10 is located within the range of the lateral support piece A19'.

[0057] The structure of the lateral support sheet A19' ensures consistency in the deformation sensitivity of the notch 6 of the arc-shaped trough body 1 at the connection between the trough frame 9 and the longitudinal ribs 10, the transverse ribs 11 and the filling layer 12.

[0058] The end of the connecting slot 20 facing the limiting flange 3 extends to the position of the limiting flange 3 , and the end of the connecting slot 20 facing away from the limiting flange 3 extends to the end of the arc-shaped slot body 1 facing away from the limiting flange 3 and is closed by the filling layer 12 .

[0059] The two ends of the connecting slot 20 are respectively closed by the limiting flanges 3 and the filling layers 12 at the corresponding positions, so as to prevent the lateral supporting sheets 19 from sliding out from the two ends of the connecting slot 20 .

[0060] The position of the limiting flange 3 corresponding to the connecting diaphragm 7 is provided with a through groove 17 matching the connecting diaphragm 7. The through groove 17 is located on one side of the notch 6 of the limiting flange 3 and passes through the end surfaces of the limiting flange 3 facing and back to the arc-shaped groove body 1. The connecting diaphragm 7 extends through the through groove 17 to the end surface of the limiting flange 3 facing back to the arc-shaped groove body 1.

[0061] The connecting diaphragm 7 extends to the side of the limiting flange 3 facing away from the arc-shaped slot body 1 , thereby ensuring the consistency of the deformation sensitivity at the notch of the entire arc-shaped slot body 1 .

[0062] The high-flow oxygen absorption tube 8 is provided with a gas source connector 22 at one end corresponding to the limiting flange 3 .
