Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to a spray anesthesia component and a spray anesthesia fiberoptic bronchoscope containing the component. Background Technology

[0002] A fiberoptic bronchoscope (or simply bronchoscope) is an instrument that uses a beam of light composed of tens of thousands of very thin fibers drawn from highly transparent glass or acrylic resin to diagnose bronchial diseases. It has a very small lumen, is flexible and bendable, has strong light guiding ability, high brightness, and a clear field of vision. It can be easily inserted into the trachea through the mouth or nose until it reaches the opening of each bronchial segment. Doctors can observe the trachea, the openings of the left and right bronchial lobes, and the condition of the mucosa under direct vision.

[0003] Currently, when performing awake endotracheal intubation, an anesthetic is usually administered at a designated site to achieve surface anesthesia. A known clinical problem is that when surface anesthesia is ineffective, the coughing and vomiting reflexes that may occur when bronchoscopy and endotracheal intubation stimulate the airway mucosa and other sensitive structures (such as the vocal cords) can reduce the patient's experience and prolong the treatment time. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a spray anesthesia component and a spray anesthesia fiberoptic bronchoscope containing the component, so as to overcome the shortcomings of the prior art.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A spray anesthesia component, comprising: a three-way valve, a spray pipe, a low oxygen flow supply end and an anesthetic supply end, wherein the side arm connector of the three-way valve is connected to the anesthetic supply end, and the other two connectors of the three-way valve are respectively connected to the spray pipe and the low oxygen flow supply end.

[0006] The beneficial effects of this invention are: the low oxygen supply end can provide a low oxygen flow, while the anesthetic supply end can provide an anesthetic. When intubating a patient, the spray anesthesia component is used in conjunction with a fiberoptic bronchoscope. Then, the low oxygen supply end and the anesthetic supply end are turned on respectively. The low oxygen flow and anesthetic enter the spray tube through a three-way valve and are then sprayed out from the spray tube. The low oxygen flow helps to keep the tube clean, avoids atomization of the fiberoptic bronchoscope, and improves the field of vision. In addition, the low oxygen flow can disperse the anesthetic to achieve better surface anesthesia, reduce the patient's cough and vomiting reflexes, increase the patient's willingness to cooperate with awake intubation, and make the patient more satisfied. The entire operation can achieve the effect of spraying while walking.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the oxygen flow rate supplied by the low oxygen supply end is 2-4 L / min.

[0009] The further beneficial effects of the above-mentioned methods are: reduced total intubation time, maintenance of oxygenation and reduced incidence of cough, and better dispersion of topical anesthesia.

[0010] Furthermore, the three-way valve includes: a three-way valve body, a valve core, and a spring. A first valve chamber and a second valve chamber are disposed opposite each other in the inner cavity of the three-way valve body. One end of the valve core is located in the first valve chamber. The other end of the valve core enters the second valve chamber and extends from the second valve chamber to the outside of the three-way valve body. The spring is arranged in the first valve chamber and is located between the bottom of the first valve chamber and the end of the valve core. The end of the valve core located in the second valve chamber has a valve hole. The movement stroke of the valve core in the first valve chamber is greater than the distance between the valve hole and the inner cavity of the three-way valve body.

[0011] The further beneficial effects of adopting the above are as follows: Under normal circumstances, the valve core keeps the three-way valve in the closed state under the elastic force of the spring. When pressure is applied to the valve core so that the entire valve core moves into the first valve chamber, the area of ​​the valve core with the valve hole will enter the inner cavity of the three-way valve body, thereby making the inner cavities of the three-way valve body on both sides of the valve core connected through the valve hole, thus entering the open state. The overall structure is simple and convenient for operators to spray while walking.

[0012] Furthermore, the three-way valve also includes a first sealing ring and a second sealing ring, which are respectively embedded in the cavity walls of the first valve chamber and the second valve chamber, and both the first sealing ring and the second sealing ring are fitted around the valve core.

[0013] The further beneficial effects of adopting the above are: the first sealing ring and the second sealing ring can seal the valve core, thereby improving the overall sealing performance of the three-way valve.

[0014] Furthermore, a guide structure is provided between the valve core and the valve core at the through-hole of the three-way valve body.

[0015] The further beneficial effect of adopting the above is that the guide structure can prevent the valve core from rotating in the three-way valve body, thereby preventing valve hole misalignment.

[0016] Furthermore, it also includes: an atomizing nozzle, with the outlet end of the spray tube connected to the atomizing nozzle.

[0017] The further beneficial effects of the above-mentioned method are as follows: the mixture in the spray tube enters the nebulizer nozzle and is atomized and sprayed out, which atomizes the anesthetic into finer particles to avoid the patient's cough and vomiting reflex, making the patient more satisfied, and also helps to better observe so as to disperse mucus secretions and blood from the lens.

[0018] Furthermore, the atomizing nozzle has multiple spray holes facing different directions.

[0019] The further beneficial effect of adopting the above is that the mixture of oxygen and anesthetic can be sprayed in multiple directions, which is more conducive to anesthesia.

[0020] Furthermore, it also includes a controller, which is electrically connected to both the low oxygen flow supply end and the anesthetic supply end.

[0021] The further beneficial effect of adopting the above is that the controller can control the low oxygen flow supply end and the anesthetic supply end to work synchronously according to the predetermined supply amount, thereby improving accuracy.

[0022] Based on the above technical solution, the present invention also provides a spray anesthesia type fiberoptic bronchoscope, including: a fiberoptic bronchoscope body and a spray anesthesia component, wherein the outlet end of the spray tube is fixed to the front end of the fiber tube on the fiberoptic bronchoscope body.

[0023] Furthermore, the three-way valve is fixed to the handle of the bronchoscope body.

[0024] The further beneficial effect of adopting the above is that during intubation, the operator can easily control the opening and closing of the three-way valve, so as to achieve anesthesia while intubating. Attached Figure Description

[0030] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0031] Example 1

[0032] like Figure 1 , Figure 2As shown, a spray anesthesia assembly includes: a three-way valve 110, a spray tube 120, a low-oxygen flow supply end 130, and an anesthetic supply end 140. The side arm connector of the three-way valve 110 is connected to the anesthetic supply end 140, and the other two connectors of the three-way valve 110 are respectively connected to the spray tube 120 and the low-oxygen flow supply end 130.

[0033] The hypoxia supply end 130 can provide hypoxia, while the anesthetic supply end 140 can provide anesthetic. When intubating a patient, the spray anesthesia component is used in conjunction with the fiberoptic bronchoscope. Then, the hypoxia supply end 130 and the anesthetic supply end 140 are turned on respectively. The hypoxia and anesthetic enter the spray tube 120 through the three-way valve 110 and are then sprayed out from the spray tube 120. The hypoxia helps to keep the bronchoscope clean, avoids atomization of the fiberoptic bronchoscope, and improves the field of vision. In addition, it can disperse the anesthetic for better surface anesthesia. Surface anesthesia is usually performed on the following sites: the inside of the nostrils, the back of the nostrils, the epiglottis, the glottis, and the vocal cords. The entire operation can achieve the effect of spraying while walking.

[0034] Example 2

[0035] like Figure 1 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0036] The oxygen flow rate supplied by the low oxygen supply end 130 is 2-4 L / min, which can reduce the total intubation time, maintain oxygenation and reduce the incidence of cough, and produce better surface anesthesia dispersion.

[0037] Example 3

[0038] like Figure 2 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0039] The three-way valve 110 includes a three-way valve body 111, a valve core 112, and a spring 113. A first valve chamber 114 and a second valve chamber 115 are disposed opposite each other within the inner cavity of the three-way valve body 111. One end of the valve core 112 is located within the first valve chamber 114; the other end of the valve core 112 enters the second valve chamber 115, and the end of the valve core 112 entering the second valve chamber 115 extends from the second valve chamber 115 to the outside of the three-way valve body 111. The spring 113 is arranged within the first valve chamber 114, and the spring 113 is located between the bottom of the first valve chamber 114 and the end of the valve core 112. The valve core 112 is located within the second valve chamber 114. One end of the valve core 110 has a valve hole 1121. The movement stroke of the valve core 112 in the first valve chamber 114 is greater than the distance between the valve hole and the inner cavity of the three-way valve body 111. Under normal circumstances, the valve core 112 keeps the three-way valve 110 in the closed state under the elastic force of the spring 113. When pressure is applied to the valve core 112 to move the entire valve core 112 into the first valve chamber 114, the area of ​​the valve core 112 with the valve hole 1121 will enter the inner cavity of the three-way valve body 111, thereby making the inner cavities of the three-way valve body 111 located on both sides of the valve core 112 connected through the valve hole 1121, thus entering the open state.

[0040] Example 4

[0041] like Figure 2 As shown, this embodiment is a further improvement based on embodiment 3, and its specific details are as follows:

[0042] The three-way valve 110 also includes a first sealing ring 116 and a second sealing ring 117. The first sealing ring 116 and the second sealing ring 117 are respectively embedded in the cavity walls of the first valve cavity 114 and the second valve cavity 115. The first sealing ring 116 and the second sealing ring 117 both cover the valve core 112. The first sealing ring 116 and the second sealing ring 117 can seal the valve core 112 and improve the sealing performance of the entire three-way valve 110.

[0043] Example 5

[0044] like Figure 2 As shown, this embodiment is a further improvement based on embodiment 3 or 4, and its specific details are as follows:

[0045] A guide structure 150 is provided between the three-way valve body 111 and the valve core 112 through the valve core 112. The guide structure 150 can prevent the valve core 112 from rotating inside the three-way valve body 111, thereby preventing the valve hole 1121 from being misaligned.

[0046] In this embodiment, the guide structure 150 can be specifically structured as follows: it includes a guide groove disposed on the valve core 112 and distributed along the moving direction of the valve core 112, and a guide block disposed outside the three-way valve body 111 and extending into the guide groove. The guide between the valve core 112 and the three-way valve body 111 is achieved through the cooperation of the guide block and the guide groove.

[0048] like Figure 1 As shown, this embodiment is a further improvement based on any one of embodiments 1 to 5, and its specific details are as follows:

[0049] The spray anesthesia assembly 1 also includes: an atomizing nozzle 160, the outlet end of the spray tube 120 is connected to the atomizing nozzle 160, the mixture in the spray tube 120 enters the atomizing nozzle 160 and is atomized and sprayed out by the atomizing nozzle 160, atomizing the anesthetic into finer particles to avoid the patient's cough and vomiting reflex, making the patient more satisfied, and also helping to better observe so as to disperse mucus secretions and blood from the lens.

[0050] Example 7

[0051] like Figure 1 As shown, this embodiment is a further improvement based on embodiment 6, and its specific details are as follows:

[0052] The atomizing nozzle 160 has multiple spray holes facing different directions, which can spray a mixture of oxygen and anesthetic in multiple directions to facilitate anesthesia.

[0053] Example 8

[0054] like Figure 1 As shown, this embodiment is a further improvement based on any one of embodiments 1 to 7, and its specific details are as follows:

[0055] The spray anesthesia assembly also includes a controller 170, which is electrically connected to the low oxygen flow supply end 130 and the anesthetic supply end 140 respectively. The controller 170 can control the low oxygen flow supply end 130 and the anesthetic supply end 140 to work synchronously according to a predetermined supply amount, thereby improving accuracy.

[0056] Example 9

[0058] A variable diameter speed-increasing structure 118 is provided in the area between the side arm connector and the valve core 112 inside the three-way valve body 111. The variable diameter speed-increasing structure 118 has a shape with a large inner diameter at both ends and a small inner diameter in the middle. The variable diameter speed-increasing structure 118 can accelerate the flow rate of the mixture of oxygen and anesthetic so that it can flow through quickly and prevent the anesthetic from flowing back.

[0059] Example 10

[0061] A turbulence structure 119 is provided in the area between the variable diameter speed-increasing structure 118 and the valve core 112 inside the three-way valve body 111. The turbulence structure 119 can disperse the anesthetic for better subsequent atomization. Since the variable diameter speed-increasing structure 118 increases the flow rate, the mixture of oxygen and anesthetic can impact the turbulence structure 119 at a faster speed, so as to better disperse the anesthetic.

[0062] In this embodiment, the turbulence structure 119 includes a circular turbulence plate and a rotating shaft. The cross-sectional dimension of the circular turbulence plate is slightly smaller than the cross-sectional dimension of the inner cavity of the three-way valve body 111. Specifically, the radius of the circular turbulence plate is 0.5 to 2 mm smaller than the radius of the inner cavity of the three-way valve body 111. The circular turbulence plate is rotatably disposed inside the three-way valve body 111 via the rotating shaft. When the mixture impacts the circular turbulence plate, the circular turbulence plate can rotate to disperse the anesthetic.

[0063] Example 11

[0064] like Figure 3 As shown, a spray anesthesia type fiberoptic bronchoscope includes: a fiberoptic bronchoscope body 2 and a spray anesthesia component 1.
