Description

Technical Field

[0001] This utility model belongs to the field of medical ventilator tubing support and auxiliary technology, specifically relating to an inflatable breathing tubing support and fixation device. Background Technology

[0002] Mechanical ventilation has become an indispensable respiratory support technique in clinical treatment, and its clinical application is becoming increasingly widespread. However, the ventilator tubing is heavy and long, presenting the following problems: First, due to gravity, the endotracheal tube is prone to sagging and friction, which can compress the nasal alae and lips, leading to pressure sores. Second, the long ventilator tubing, especially at the 360° spiral connector, is prone to twisting and becoming low-lying, resulting in fluid accumulation and reflux into the endotracheal tube at the patient's end, thus increasing the incidence of ventilator-associated pneumonia (VAP). To address these issues, we often use disposable rubber gloves to inflate and support the 360° spiral connector or the ventilator tubing in clinical practice, but this has not been entirely effective. On the one hand, the inflation pressure is difficult to control; over-inflation can cause the tubing to be supported at too large an angle, resulting in pressure injury to the upper part of the nasal alae of patients with nasotracheal intubation. Insufficient inflation will not provide enough support for the breathing tubing, making it prone to fluid accumulation inside the tubing and reflux into the endotracheal tube. The weight of the tubing will also press against the skin, thus failing to effectively prevent pressure sores and ventilator-associated pneumonia (VAP). Furthermore, disposable rubber gloves used in clinical settings are prone to leakage during inflation, failing to provide adequate support and requiring frequent changes, increasing the workload of medical staff.

[0003] A search revealed a Chinese patent with publication number CN203736654U, which discloses a multifunctional breathing tubing support indicator bag. This device supports the breathing tubing through a groove formed by left and right support columns after inflation, preventing water from flowing back into the ventilator tubing. However, the device can only support the ventilator tubing and cannot simultaneously support the endotracheal tube and the 360° spiral connector / breathing tubing. The 360° spiral connector is located in a low position and is prone to water accumulation, which can lead to ventilator-associated pneumonia (VAP).

[0004] A search revealed Chinese patent CN213191970U, which discloses a respiratory tube fixation bracket. This bracket can be fixed to a horizontal bar on the side of a hospital bed using a fixator. The patient's respiratory tube or other intubation tube is then fixed in an arc-shaped groove and secured with a fixing plate to prevent dislodgement. The fixing plate is secured to the arc-shaped groove with a magnet, making operation convenient. However, the iron plate and magnet used in this device are prone to oxidation and demagnetization during use, and are easily broken, which is not conducive to long-term use. Furthermore, the neodymium iron boron magnet material used is expensive, resulting in a high cost for the bracket. Additionally, the device cannot flexibly adjust the position of the fixator during use, which is inconvenient.

[0005] How to solve the above problems has become an urgent technical issue. Utility Model Content

[0006] The purpose of this invention is to provide an inflatable breathing tubing support and fixation device that is easy to use and can effectively reduce the incidence of ventilator-associated pneumonia.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] This utility model provides an inflatable breathing tube support and fixation device, including a support airbag and a breathing tube fixation airbag. The support airbag is used to support the endotracheal tube at the patient end, and the breathing tube fixation airbag is used to support and fix a 360-degree spiral connector or breathing tube. A telescopic and swingable connector is provided between the support airbag and the breathing tube fixation airbag, and the support airbag and the breathing tube fixation airbag are connected through the connector. A breathing tube fixation structure for placing and fixing the breathing tube is provided at the top of the breathing tube fixation airbag.

[0009] Furthermore, the breathing tubing fixing structure includes a downwardly sloping arc-shaped slope on the back of the breathing tubing fixing airbag, and a pair of elastic straps are provided at the highest point of the arc-shaped slope and at the middle of the arc-shaped descending part.

[0010] Furthermore, it also includes two air inflator lines, one end of which is connected to the support airbag or the breathing tube fixing airbag and the other end of which is detachably connected to the inflation airbag, and a three-way valve is provided on the air inflator line.

[0011] Furthermore, a pressure gauge for detecting air pressure is also installed on the air pumping line.

[0012] Furthermore, the connector is a malleable corrugated tube, and its two ends are respectively connected to the support airbag and the breathing tubing fixing airbag, and a switch valve is installed on the connector.

[0013] Furthermore, the support airbag includes a support portion and two protruding ears. The support portion is connected to the connector, and both protruding ears are connected to the support portion and are symmetrically arranged on the top of the support portion to form the shape of a rabbit's head.

[0014] Furthermore, it also includes at least two fixing straps, one end of which is fixedly connected to the support and the breathing tube fixing airbag respectively, and the other end of each fixing strap is fixedly connected to a clip.

[0015] Due to the adoption of the above structure, the beneficial effects of this utility model are as follows:

[0016] 1. This invention, through the combined use of a support cuff and a breathing tube fixing cuff, can separately support the endotracheal tube and the breathing tube, reducing the pressure of the breathing tube's weight on the skin around patients with oral or nasal endotracheal intubation, thereby effectively preventing pressure sores. Therefore, this invention is convenient to use, simple and easy to operate, highly flexible, and suitable for various angles and positions in clinical settings. It also reduces the twisting and traction of the breathing tube in patients with endotracheal intubation or tracheostomy. Compared to traditional inflatable disposable rubber gloves, it is more time-saving and labor-saving. Furthermore, this invention can be sterilized and reused.

[0017] 2. This utility model creates a downward-sloping arc-shaped surface on the back of the breathing tubing fixing bag, which facilitates the flow of water from the tubing into the water collection cup, thus better collecting the water and effectively preventing water from flowing back into the endotracheal tube, thereby further reducing the incidence of VAP.

[0018] The present invention will become clearer from the following description and in conjunction with the accompanying drawings, which are used to explain the embodiments of the present invention. Attached Figure Description

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0020] Figure 1 This is a schematic diagram of the overall structure of the present invention in use. Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figure 1This utility model provides an inflatable breathing tube support and fixation device, including a support airbag 1 and a breathing tube fixation airbag 3. The support airbag 1 is used to support the endotracheal tube at the patient end, and the breathing tube fixation airbag 3 is used to support and fix the 360-degree spiral connector or the breathing tube, thereby reducing the pressure of the breathing tube and endotracheal tube on the skin around the patient with oral or nasal endotracheal intubation, effectively preventing pressure sores, better collecting accumulated water, and effectively avoiding water reflux in the breathing tube and the endotracheal tube itself, thereby reducing the incidence of VAP. A telescopic and swingable connector 2 is provided between the support airbag 1 and the breathing tube fixation airbag 3, and the support airbag 1 and the breathing tube fixation airbag 3 are connected by the connector 2, which has great flexibility and is suitable for various angles and positions in clinical practice, effectively avoiding the twisting and pulling of the breathing tube. A breathing tube fixation structure 4 is provided at the top of the breathing tube fixation airbag 3 for placing and fixing the breathing tube, effectively preventing the breathing tube from unplanned detachment from the breathing tube fixation airbag 3.

[0023] In this invention, the breathing tubing fixing structure 4 includes a downwardly sloping arc-shaped slope 401 on the back of the breathing tubing fixing airbag 3. A pair of elastic straps 402 are provided at the highest point and the middle of the downward sloping portion of the arc-shaped slope 401. The elastic straps 402 are used to secure the breathing tubing, and the space between the two elastic straps 402 serves as a groove for placing the breathing tubing. The curvature of the arc-shaped slope 401 creates a downward slope in the breathing circuit, facilitating the flow of accumulated water from the tubing into the collection cup, thereby reducing the risk of aspiration pneumonia.

[0024] This invention also includes two inflation lines 5. One end of each inflation line 5 is connected to the support airbag 1 or the breathing tube fixing airbag 3, and the other end of each inflation line 5 is detachably connected to an inflation balloon 6. A three-way valve 7 is provided on each inflation line 5. The two inflation lines 5 are used to inflate the support airbag 1 and the breathing tube fixing airbag 3 respectively, allowing for better control of the inflation pressure. The inflation balloon 6 is detachably connected to the inflation line 5 via a plug-in, threaded, or snap-fit ​​connection. In use, the valve of the three-way valve 7 is turned to connect both ends of the inflation line 5 to the inflation balloon 6, the support airbag 1, or the breathing tube fixing airbag 3 respectively. Then, the inflation balloon 6 is repeatedly squeezed, allowing external air to be pumped into the support airbag 1 or the breathing tube fixing airbag 3 through the inflation line 5 until both the support airbag 1 and the breathing tube fixing airbag 3 inflate, just enough to support the endotracheal tube, 360° spiral connector, or... In the breathing circuit, rotate the valve of the three-way valve 7 again to block the end of the air inflator tube 5 near the support airbag 1 or the breathing tube fixing airbag 3 to prevent gas leakage. If over-inflated, the valve of the three-way valve 7 can be slightly rotated to allow the support airbag 1 or the breathing tube fixing airbag 3 to connect with the outside through the air inflator tube 5 and the three-way valve 7 in sequence, allowing a small amount of gas in the support airbag 1 and / or the breathing tube fixing airbag 3 to be discharged to the outside. After use, rotate the valve of the three-way valve 7 to allow the support airbag 1 or the breathing tube fixing airbag 3 to connect with the outside through the air inflator tube 5 and the three-way valve 7 in sequence, allowing the gas in the support airbag 1 and / or the breathing tube fixing airbag 3 to be discharged to the outside and deflated.

[0025] In this invention, a pressure gauge 8 for detecting air pressure is also provided on the air inflator 5. The pressure gauge 8 is an air pressure gauge, which facilitates real-time monitoring of the internal air pressure of the support airbag 1 and the breathing tube fixing airbag 3 during the inflation process, preventing excessive air from being pumped in and causing the support airbag 1 and the breathing tube fixing airbag 3 to rupture.

[0026] In this utility model, the connector 2 is a malleable corrugated tube that can extend and retract along the length of the malleable corrugated tube and swing to present different angles; the two ends of the connector 2 are respectively connected to the support airbag 1 and the breathing tube fixing airbag 3, and a switch valve 201 is installed on the connector 2. In use, opening the switch valve 201 connects the support airbag 1 and the breathing tubing fixing airbag 3 via the connector 2. In this case, inflating either the support airbag 1 or the breathing tubing fixing airbag 3 via any inflation line 5 will inflate both airbags. Closing the switch valve 201 disconnects the support airbag 1 from the breathing tubing fixing airbag 3. In this case, inflating either airbag 1 or the breathing tubing fixing airbag 3 via the two inflation lines 5 allows for flexible adjustment of the inflation volume of both airbags, creating a pressure difference between them. This better adapts to the different shapes and placement requirements of the support airbag 1 and the breathing tubing fixing airbag 3, achieving a better support effect.

[0027] In this invention, the support airbag 1 includes a support portion 101 and two protruding ears 102. The support portion 101 is connected to the connector 2, and both protruding ears 102 are connected to the support portion 101. The two protruding ears 102 are symmetrically arranged on the top of the support portion 101 to form a rabbit head shape. In use, the space between the two protruding ears 102 serves as a groove for placing the endotracheal tube at the patient's end.

[0028] This invention also includes at least two fixing straps 9. One end of each fixing strap 9 is fixedly connected to the support part 101 and the breathing tube fixing airbag 3, and the other end of each fixing strap 9 is fixedly connected to a clip 10. In use, by clamping the external object with the clip 10, the position of the support airbag 1 and the breathing tube fixing airbag 3 can be effectively fixed, improving the stability during use.

[0029] In use, this invention first inflates the support bag 1 and the breathing tubing fixing bag 3 using the corresponding inflation balloons 6, causing them to expand. Then, the endotracheal tube is placed between the two protruding lugs 102 of the support bag 1, and the ventilator tubing is placed on the breathing tubing fixing bag 3. The ventilator tubing is then secured with two pairs of elastic straps 402, causing it to slope downwards along the curved surface 401, ensuring the water collection cup is in a low position to guide the accumulated fluid towards it. If necessary, the support bag 1 and / or the breathing tubing fixing bag 3 can be further secured with clips 10. Therefore, this invention is convenient to use and can effectively reduce the incidence of ventilator-associated pneumonia.
