Example

Please refer to FIG. 1 , which is a schematic structural diagram of the accessory 100 . This embodiment provides an accessory 100 which is mainly used on a tracheal tube 200 . The auxiliary part 100 is used in conjunction with the tracheal tube 200 to make the postoperative care of the patient more convenient and the patient more comfortable.

After a tracheotomy, the patient needs to rely on a tracheal tube for breathing. Generally, in this case, the gas will enter and exit the respiratory tract directly through the tracheal tube, and the gas will no longer be filtered and humidified through the nasal cavity and upper respiratory tract. This way of breathing can easily cause various respiratory discomforts such as lung infection, irritating cough, and phlegm scab formation. Moreover, patients with tracheotomy usually have a lot of sputum and are prone to sputum splashing. In order to improve the postoperative comfort of such patients, this embodiment proposes an accessory 100 that can be used in conjunction with the tracheal tube 200 .

Please refer to FIG. 1 and FIG. 2 . FIG. 2 is a schematic structural view of the expiratory channel and the sputum collection channel. The accessory 100 mainly includes a multi-way tube 110 , a humidifying component 130 and a sputum collecting component 160 . Wherein, the multi-way pipe 110 can select a corresponding number of outlets according to user needs. In this embodiment, the multi-way pipe 110 adopts a four-way pipe (in other embodiments, it may be a joint pipe with five-way, six-way or other channels), and there are four interfaces in total.

The multi-way tube 110 includes a first connecting tube 112 , a second connecting tube 114 , a third connecting tube 116 and a fourth connecting tube 118 . Wherein, the first connecting pipe 112 is opposite to the second connecting pipe 114 . The tracheal cannula 200 communicates with the first mouth of the first connecting tube 112 (not marked in the figure), and the sputum collection assembly 160 communicates with the second mouth of the second connecting tube 114 (not marked in the figure), so as to facilitate tracheal The sputum in the sputum can be directly collected into the sputum collection component 160, avoiding the splashing of sputum, better ensuring the cleanliness of the patient's wound, and more convenient for medical staff to care for. The humidifying assembly 130 communicates with a third opening (not shown in the figure) of the third connecting pipe 116 . The humidifying component 130 humidifies the air entering the patient's trachea to make breathing more comfortable for the patient. At the same time, the humidification component 130 and the phlegm collection component 160 are located on different channels, which further reduces the mutual interference between the two functions of humidification and phlegm collection, so that the two functions can be performed simultaneously more smoothly. Wherein the fourth mouth portion (not shown in the figure) of the fourth connecting pipe 118 can be specially used for the patient to exhale gas.

In order to understand the use of the accessory 100 more clearly, three working routes will be described in detail below.

1. Inhalation route

The gas is inhaled by the third connecting tube 116 where the humidifying component 130 is located, and the inhaled gas will be humidified before entering the patient's respiratory tract, avoiding the patient's irritating cough or other respiratory discomfort caused by dry air. Currently common humidification methods include, for example, covering the opening of the tracheal tube with wet gauze. In this method, the time for keeping the humidity is short, and it is necessary to pay attention to changing the gauze frequently; and the gauze is not effectively fixed, and it is easy to fall off. Some also use the way of connecting to the atomizer to realize gas humidification through atomization. However, this method requires the use of a nebulizer, which requires a power source, is not portable, and the patient cannot move freely. In this embodiment, the humidifying component 130 uses a humectant 132 . The humectant 132 is made of a material that has a strong water absorption function and can slowly release water, for example, it may include superabsorbent resin, sodium diatomate, polyacrylamide, and the like. The humectant 132 should be selected from materials that are highly safe to the human body, reusable, low in cost, and have a long moisturizing time, preferably superabsorbent resin. Of course, other moisturizing agents 132 with similar functions are also within the protection scope of the present invention. This superabsorbent resin can also absorb other medicinal liquids (medical liquids designated by medical personnel to be beneficial to patients), slowly release them into the gas, and act on the airway for a long time. The use of the moisturizing agent 132 not only solves the humidity problem of the patient's breathing gas, but also solves the problem of portability, making the postoperative care of the patient more convenient. Compared with the commonly used wet gauze, the moisturizing time of the moisturizing agent 132 is significantly prolonged, which reduces the trouble of frequently adding water and replacing the wet gauze.

Since the gas will pass directly through the tracheal tube 200 into and out of the respiratory tract, and the gas will no longer be filtered through the nasal cavity and upper respiratory tract, therefore, in order to improve the filtering effect on the gas, the accessory 100 also includes a filter assembly. Both the filter assembly and the humidification assembly 130 are mounted on the fixed box 102, the fixed box 102 communicates with the third connecting pipe 116, and the moisturizing agent 132 is located between the third connecting pipe 116 and the filter assembly. In this embodiment, the filter assembly uses a filter layer 134 . The filtering layer 134 is made of materials with air filtering function (such as non-woven fabric, filter cotton, activated carbon, etc.), and can filter dust, microorganisms, etc. in the air. The air is filtered and humidified in turn, and then enters the patient's respiratory tract, avoiding various respiratory discomforts such as lung infection, irritating cough, and phlegm scab formation caused by poor air quality. As shown in FIG. 1 , the direction of the solid arrow in FIG. 1 represents the flow direction of gas during inhalation. (In other embodiments, according to the use environment, a heating component can also be installed on the fixed box 102, and the gas entering the respiratory tract can be heated in the form of electric heating, chemical heating, etc., so as to improve the user's health in a cold environment. breathing comfort.)

The filter assembly and humidification assembly 130 can also be connected in a replaceable and detachable manner. When the filtering and humidification effects are significantly reduced after being used for a long time, the filter assembly and humidification assembly 130 can be replaced accordingly without replacing the entire Accessory 100. The detachable arrangement of the filter assembly and the humidification assembly 130 in the fixed box 102 can adopt various existing common arrangement methods, which are not specifically limited in this embodiment.

Further, a first one-way valve 120 is also disposed in the third connecting pipe 116 . When gas is inhaled, the humidified gas can enter into the respiratory tract of the patient through the first one-way valve 120 , while the exhaled gas cannot be exhaled through the first one-way valve 120 . Along the direction from the third port to the first port, the third port, the first one-way valve 120 and the first port are sequentially communicated, and the first one-way valve 120 can only conduct in the suction direction.

Further, in order to facilitate fixing the accessory 100 on the patient's body, an arc portion 104 is provided on the side of the fixing box 102 close to the tracheal tube 200 , as shown in FIG. 1 . The arc portion 104 is close to the patient's neck when worn, and the arc-shaped contact surface is more conducive to fit the patient's neck, with higher wearing stability and higher user comfort. The side of the arc portion 104 close to the endotracheal tube 200 (ie close to the neck) may also be provided with a silicone pad (not shown in the figure). Silicone pad is a flexible material that is non-allergic to the skin. Its use can not only avoid the allergic phenomenon of skin discomfort in a small number of patients, but also improve the comfort of contact with the skin. Of course, in other embodiments, the silicone pad can also be replaced by other flexible materials, such as air pads, soft pads, and the like.

In order to improve the cleanliness of the patient during breathing, the end of the first connecting tube 112 close to the first mouth is also provided with a protective member 122 . In this embodiment, the protective member 122 is a protective film, and the protective film is pasted on the exposed part of the tracheal tube 200 and the neck skin to protect the exposed part of the tracheal tube 200 from contamination. At the same time, it can better ensure that the gas entering and exiting the patient's airway circulates in the accessory 100, and can also improve the stability of the accessory 100 during breathing.

In order to fix the auxiliary part 100 more conveniently, the fixing box 102 can also be provided with a fixing belt 105, and the upper end of the fixing belt 105 is provided with a first fixing piece 106, and a second fixing piece 106 matched with the first fixing piece 106 is also arranged on the four-way pipe. The fixing part 124 (the specific position on the four-way pipe may not be limited, as long as it can be matched with the first fixing part 106, and of course other functions cannot be affected). The medical personnel can use the fixing belt 105 to bind the fixing box 102 to the patient's neck. The cooperation of the two fixing parts can fix the fixing belt 105, and the two fixing parts can adopt common detachable matching methods such as buckle and Velcro, which are not specifically limited in this embodiment. Since different patients have different neck sizes, in order to better fix the accessory 100 on the necks of different patients, the fixing belt 105 can adopt a length-adjustable structure or a material with stretch properties.

2. Exhalation route

The fourth connecting pipe 116 is provided with a second one-way valve 126 . Along the direction from the first port to the second one-way valve 126 , the first port, the second one-way valve 126 and the fourth port communicate in sequence. As shown in Figure 2, the solid arrows represent the direction of gas flow during exhalation. The second one-way valve 126 is only conducted in the exhalation direction, and the inhaled gas will not pass through the one-way valve. When a conventional tracheal tube is used, most of the inhalation and exhalation are through the same channel, causing part of the exhaled carbon dioxide to be re-inhaled into the respiratory tract, which can easily cause symptoms such as hypoxia and chest tightness. In this embodiment, through the setting of the first one-way valve 120 and the second one-way valve 126, the inhalation and exhalation channels can be separated, which makes up for the defect that the same channel is used for inhalation and exhalation, allowing patients to Breathing is easier.

3. Sputum collection route

As shown in Figure 2, the direction of the dotted arrow in Figure 2 represents the direction of sputum collection. The sputum coughed up by the patient's respiratory tract will be collected into the sputum collection component 160 . The sputum-collecting component 160 can be a sputum-collecting bag, and the sputum-collecting bag can be tied to the second connecting pipe 114 . When coughing, the sputum splashes forward into the sputum collection bag, which prevents the sputum from splashing and helps to keep the patient's respiratory cavity clean. The first connecting pipe 112 and the second connecting pipe 114 are arranged oppositely, and jointly define and form a sputum collection channel. In this embodiment, the distance between the interface of the second connecting tube 114 and the opening of the tracheal tube 200 is very short. When it is necessary to carry out relevant medical operations, take off the sputum collection bag, and the second mouth becomes the opening of the medical operation channel, and medical operations such as inserting sputum suction tubes and oxygen tubes can be performed without removing all other items, which greatly improves medical treatment. Ease of operation. In order to ensure more convenient related medical operations later, the length of the second connecting tube 114 may be 10-100 mm, of course, other lengths may also be used in other embodiments. At present, many similar products do not retain medical operation channels. When medical operations are required (insertion of sputum suction tubes, oxygen tubes, etc.), all products need to be removed, which is very inconvenient.

The working principle of accessory 100 is:

The accessory 100 is mounted on the tracheal tube 200 for use, and the tracheal tube 200 communicates with the respiratory tract of the patient.

When inhaling, the gas enters the humidifying component 130 after being filtered by the filter layer 134, and the gas is humidified by the humectant 132, and then enters the inside of the four-way tube through the first one-way valve 120, and then enters the human body through the opening of the tracheal tube 200 Exhale the airway, at this time the second one-way valve 126 is in a closed state. The air is filtered and humidified in turn, and then enters the patient's respiratory tract, avoiding various respiratory discomforts such as lung infection, irritating cough, and phlegm scab formation caused by poor air quality. When exhaling, gas enters the four-way tube from the opening of the tracheal tube 200, and is discharged into the surrounding environment through the second one-way valve 126, and the first one-way valve 120 is in a closed state at this time. Through the setting of the first one-way valve 120 and the second one-way valve 126, the inhalation and exhalation channels can be separated, which makes up for the defect that the same channel is used for inhalation and exhalation, so that the patient can breathe more smoothly. When coughing, the sputum splashes forward into the sputum collection bag, which prevents the sputum from splashing and helps to keep the patient's respiratory cavity clean. The present invention creatively separates inhalation, exhalation, and sputum splashing passages through the four-way pipe. The accessory 100 integrates "filtering, humidification, anti-sputum splashing, separation of exhalation and inhalation channels, retention of medical channels, and portability". It can moisturize for a long time and reduce humidification operations.

This embodiment also provides a tracheal tube 200, which mainly includes the above-mentioned accessory 100. The use of the tracheal tube 200 with the above-mentioned accessory 100 can make the patient more comfortable and make the care of the medical staff more convenient.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
