Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a fiberoptic bronchoscope cannulation fixation structure. Background Technology

[0002] A fiberoptic bronchoscope, also known as a fiberoptic bronchoscope, requires a fixed structure to secure the endotracheal tube under bronchial guidance, eliminating the need for manual fixation and facilitating insertion of the scope.

[0003] The patent with publication number CN218075956U describes a transoral fiberoptic bronchoscope-guided endotracheal intubation fixation device. This device includes a C-shaped cover plate. Silicone strips are fixedly connected to the top and bottom of the inner wall of the C-shaped cover plate. An A-hole is opened on one side of the front of the C-shaped cover plate, and a semi-circular cylinder is fixedly connected inside the A-hole. An B-hole is opened on the other side of the front of the C-shaped cover plate, and a sleeve is fixedly connected inside the B-hole. A protrusion is fixedly connected to the inner bottom wall of the sleeve. In use, the semi-circular cylinder, when inserted into the oral cavity, can press down the tongue, opening up the oral cavity space. The space in the middle of the semi-circular cylinder facilitates medical personnel's observation of the oral cavity and allows for timely removal of foreign objects, preventing damage or compression of the intubation tube caused by clenched teeth.

[0004] When the above device is implemented, the C-shaped movable block is pushed by the fixing bolt, so that the endotracheal tube can be fixed inside the sleeve and will not slip. However, manually turning the fixing bolt is cumbersome, and female medical staff do not have enough hand strength to turn it. The instruments need to be prepared in advance, which affects efficiency. In addition, the C-shaped movable block will squeeze and rub against the C-shaped movable block when positioning the endotracheal tube, which can easily cause scratches on its outer edge. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a fiberoptic bronchoscope cannula fixation structure, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0006] To achieve the above objectives, this application adopts the following technical solution: a fiberoptic bronchoscope cannula fixing structure, including a positioning plate, a sleeve fixedly installed on the inner wall of the positioning plate, an airbag one fixedly installed on the bottom of the inner wall of the sleeve, a round tube inserted into the inner wall of the airbag one, an airbag two fixedly installed on the top of the inner wall of the sleeve, a connecting tube fixedly connected to the inner cavity of the airbag two, a threaded tube threadedly connected to the outer edge of the other end of the connecting tube, an inflation tube threadedly connected to the inner wall of the threaded tube, a control valve one installed on the inner wall of the connecting tube, and a small press-type inflation pump fixedly connected to the end of the inflation tube away from the threaded tube.

[0007] In a preferred embodiment, two connecting holes are symmetrically provided on the inner wall. Strap 1 and Strap 2 are fixedly connected to the inner walls of the two connecting holes respectively. Hook and loop fastener 1 is fixedly connected to the side of Strap 1 away from the positioning plate, and Hook and loop fastener 2 is fixedly connected to the side of Strap 2 away from the positioning plate.

[0008] By adopting the above technical solution, the first and second straps can be attached to the patient's head and then bonded together using Velcro closures, thereby stably installing the first and second straps on the patient's head and achieving the positioning of the positioning plate.

[0009] In a preferred embodiment, a semicircular plate is fixedly installed on the outer wall of the positioning plate, and a semicircular groove is provided on the top of the semicircular plate corresponding to the position of the semicircular plate.

[0010] By adopting the above technical solution, when the semicircular plate is placed in the oral cavity, it can press down the tongue, making it convenient for medical staff to observe the condition inside the oral cavity. At the same time, it can promptly clean foreign objects in the oral cavity. When the tube body is inserted, the semicircular plate can open the oral cavity to prevent damage or compression to the tube body caused by the teeth closing.

[0011] In a preferred embodiment, the first airbag and the second airbag are semi-circular on one side of each other, and the intubation body is located at the middle position of the first airbag and the intubation body.

[0012] By adopting the above technical solution, the inflated airbag II, together with the airbag P, can be used to position the intubation tube body, ensuring that the intubation tube body will not shake randomly during use. At the same time, when the airbag II is in a deflated state, the intubation tube body can be easily removed to the outside without friction.

[0013] In a preferred embodiment, the inner wall of the inflation tube is fixedly connected to an exhaust pipe, and a control valve is installed on the outer edge of the exhaust pipe.

[0014] By adopting the above technical solution, when the control valve is in the open state, the gas in the inner cavity of the airbag can be discharged to the inner cavity of the inflation tube through the connecting tube, and then discharged to the outside through the exhaust pipe, thereby achieving the effect of deflation of the inner cavity of the airbag.

[0015] In a preferred embodiment, two comfort pads are symmetrically fixedly installed on the side of the positioning plate near the semicircular plate, and both comfort pads are made of polyurethane.

[0016] By adopting the above technical solution, when the first and second straps are bound to the patient's head, the side of the two comfort pads away from the positioning plate can come into contact with the patient's skin, so that the positioning plate will not come into direct contact with the skin, thus improving the patient's comfort when the positioning plate is installed on the patient's face and preventing contact with hard objects.

[0017] In a preferred embodiment, a tray is mounted on the top of the positioning plate, and the small press-type air pump is placed on the inner wall of the tray.

[0018] By adopting the above technical solution, the small press-type air pump can be stored and stored, and a support point can be provided when pressing the small press-type air pump, making it easier for medical staff to press it forcefully.

[0019] The beneficial effects of this application are:

[0020] 1. This fiberoptic bronchoscope cannula fixation structure generates gas by pressing a small press-operated air pump, which is then discharged through the inflation tube and connecting tube into the inner cavity of the second airbag. This causes the inner cavity of the second airbag to be inflated, which, together with the airbag, positions the cannula body, improving the ease of positioning the cannula body. It is also suitable for cannula bodies of different diameters at the top, making it easy for most people to use without the need for auxiliary instruments. When it is necessary to remove the cannula body, the control valve can be opened to allow the gas in the inner cavity of the second airbag to be discharged to the outside through the connecting tube and inflation tube, thereby deflating the inner cavity of the second airbag and facilitating the removal of the cannula body without friction during the removal process.

[0021] 2. This fiberoptic bronchoscope cannula fixation structure attaches strap one and strap two to the patient's head and then uses Velcro one and Velcro two to bond them together, thereby stably installing strap one and strap two on the patient's head and achieving positioning of the positioning plate, which is convenient for patients of different body sizes.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] Reference Figure 1-4 A fiberoptic bronchoscope cannula fixation structure includes a positioning plate 1, a sleeve 9 fixedly installed on the inner wall of the positioning plate 1, an airbag 10 fixedly installed at the bottom of the inner wall of the sleeve 9, a round tube 11 inserted into the inner wall of the airbag 10, an airbag 2 13 fixedly installed at the top of the inner wall of the sleeve 9, one end of a connecting tube 14 fixedly connected to the inner cavity of the airbag 2 13, a threaded tube 16 threadedly connected to the outer edge of the other end of the connecting tube 14, an inflation tube 17 threadedly connected to the inner wall of the threaded tube 16, a control valve 15 installed on the inner wall of the connecting tube 14, and a small press-type inflation pump 18 fixedly connected to the end of the inflation tube 17 away from the threaded tube 16.

[0029] See Figure 1 and Figure 2 Two connecting holes 7 are symmetrically opened on the inner wall of the device. Straps 1 3 and 2 5 are fixedly connected to the inner walls of the two connecting holes 7 respectively. Hook and loop fastener 4 is fixedly connected to the side of strap 1 away from the positioning plate 1, and hook and loop fastener 6 is fixedly connected to the side of strap 2 5 away from the positioning plate 1. This allows straps 1 3 and 2 5 to be attached to the patient's head and then the hook and loop fastener 4 and 2 6 to be bonded together. This allows straps 1 3 and 2 5 to be stably installed on the patient's head, thereby achieving the positioning of the positioning plate 1.

[0030] See Figure 1 and Figure 2 A semicircular plate 2 is fixedly installed on the outer wall of the positioning plate 1. A semicircular groove is opened on the top of the semicircular plate 2, which corresponds to the position of the semicircular plate 2. When the semicircular plate 2 is placed in the oral cavity, the semicircular plate 2 can press down the tongue, making it convenient for medical staff to observe the condition inside the oral cavity. At the same time, it can also clean foreign objects in the oral cavity in time. When the intubation body 12 is inserted, the semicircular plate 2 can open the oral cavity to prevent the teeth from closing and causing damage or compression to the intubation body 12.

[0031] See Figure 3 and Figure 4The first airbag 10 and the second airbag 13 are semi-circular on one side of each other. The intubation body 12 is located in the middle of the first airbag 10 and the intubation body 12. This allows the inflated second airbag 13 to work with the first airbag 10 to position the intubation body 12, ensuring that the intubation body 12 will not shake during use. At the same time, when the second airbag 13 is in a deflated state, the intubation body 12 can be easily removed to the outside without friction.

[0032] See Figure 4 An exhaust pipe 19 is fixedly connected to the inner wall of the inflation tube 17. A control valve 20 is installed on the outer edge of the exhaust pipe 19, so that when the control valve 20 is in the open state, the gas in the inner cavity of the airbag 13 can be discharged to the inner cavity of the inflation tube 17 through the connecting pipe 14, and then discharged to the outside through the exhaust pipe 19, thereby achieving the effect of deflation of the inner cavity of the airbag 13.

[0033] See Figure 3 Two comfort pads 8 are symmetrically fixed on the side of the positioning plate 1 near the semicircular plate 2. Both comfort pads 8 are made of polyurethane, so that when the first strap 3 and the second strap 5 are bound to the patient's head, the side of the two comfort pads 8 away from the positioning plate 1 can come into contact with the patient's skin. Thus, the positioning plate 1 will not come into direct contact with the skin, which improves the patient's comfort when the positioning plate 1 is installed on the patient's face and will not come into contact with hard objects.

[0034] See Figure 1 - Figure 4 A tray is installed on the top of the positioning plate 1, and a small press-type air pump 18 is placed on the inner wall of the tray, so that the small press-type air pump 18 can be stored and stored, and a support point can be provided when pressing the small press-type air pump 18, making it easier for medical staff to press it forcefully.

[0035] Working principle: When using this device, firstly, the sterilized round tube 11 can be inserted into the inner wall of the first airbag 10. Then, the intubation body 12 can be placed in the middle of the first airbag 10 and the second airbag 13. Then, the other end is slowly inserted into the patient's mouth. At the same time, the semi-circular plate 2 can be placed in the mouth. The semi-circular plate 2 can press down the tongue, making it easier for medical staff to observe the condition inside the mouth and to clean foreign objects in the mouth in time. When the intubation body 12 is inserted into the mouth, the semi-circular plate 2 can open the mouth to prevent damage or compression of the intubation body 12 caused by the teeth closing. Then, the intubation body 12 and the round tube 11 can be sent into the mouth at the same time. Then, the first strap 3 and the second strap 5 can be attached to the patient's head and then glued together by the Velcro 4 and the second Velcro 6. The second belt 5 is stably installed on the patient's head to position the positioning plate 1. Then, by pressing the small press-to-inflate pump 18, gas is generated and discharged through the inflation tube 17 and the connecting tube 14 into the inner cavity of the second airbag 13, thereby inflating the inner cavity of the second airbag 13. This, together with the first airbag 10, positions the cannula body 12. When it is necessary to remove the cannula body 12, the control valve 20 can be opened to allow the gas in the inner cavity of the second airbag 13 to be discharged to the outside through the connecting tube 14 and the inflation tube 17, thereby deflating the inner cavity of the second airbag 13 and facilitating the removal of the cannula body 12 without friction during the removal process. After the second airbag 13 is impacted, the control valve 15 can be closed, and the threaded tube 16 can be rotated to disengage the connection between the connecting tube 14 and the inflation tube 17. This allows the small press-to-inflate pump 18 to be disconnected from the connecting tube 14, reducing the weight of the device itself.
