Description

Technical Field

[0001] The utility model belongs to the technical field of medical consumables, and in particular relates to an animal tracheal intubation tube matched with a respiratory anesthesia machine. Background Art

[0002] Anesthesia, as a medical treatment, has become increasingly recognized and utilized within the medical community. Consequently, high-tech support is required for anesthesia techniques. Air anesthesia machines are lightweight and versatile, utilizing both air and oxygen as carrier gases to assist and control respiration, meeting various surgical requirements.

[0003] Endotracheal tubes, essential instruments in hospital anesthesiology, emergency, and laryngology departments, are becoming increasingly common. Because endotracheal tubes are made of relatively soft plastic and lack rigidity, endotracheal intubation is a nearly daily procedure for every anesthesiologist. Endotracheal intubation involves inserting a tube (consisting of a cannula and a stylet) through the patient's mouth, pharynx, and larynx into the patient's trachea during general anesthesia, after the patient has lost consciousness, to provide assisted breathing or mechanical ventilation. However, most of the current endotracheal tubes are for human use, and the tube itself is bendable to meet human needs. However, during the diagnosis and treatment of animals, the animal is placed in a supine position with its head tilted back for intubation. Its mouth, throat and trachea are in the same longitudinal direction, approximately in a straight line. Therefore, the intubation action is not convenient and requires more time. However, if the intubation time is too long, it is easy to cause the animal to suffocate. At the same time, the current existing tubes are short, and the distance from the animal's mouth to its glottis is long. In addition, the endotracheal tubes suitable for large animals are relatively thick. Therefore, the area near the animal's glottis is easily irritated and becomes edematous during intubation, which is more difficult to complete the intubation operation. In addition, the air bag provided on the front outer wall of the endotracheal tube and the inflation connecting tube of the pressure sensing device are easily worn off by the animal's teeth, making it unable to assist the animal's breathing and mechanical ventilation, and the rear end connection between the respiratory anesthesia machine circuit tube and the endotracheal tube is also easy to fall off. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of the present utility model is to provide an animal endotracheal intubation tube for use with a respiratory anesthesia machine. The provided animal endotracheal intubation tube for use with a respiratory anesthesia machine is stably connected to the respiratory anesthesia machine, and the inflation connecting tube is not easily worn off, which can effectively shorten the intubation time to avoid suffocation of the animal.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] The utility model provides an animal tracheal intubation tube for use with a matching respiratory anesthesia machine. The animal tracheal intubation tube for use with a matching respiratory anesthesia machine comprises:

[0007] The cannula body has a diameter of 6F and a length of 40 cm;

[0008] The airbag is arranged on the circumferential outer wall adjacent to the first end of the cannula body, and the airbag is connected to the pressure sensing device through an inflation connecting tube; the outside of the inflation connecting tube is wrapped with a layer of metal wire mesh.

[0009] As a further description of the above technical solution, the second end of the cannula body is connected to the respiratory anesthesia machine through a connector.

[0010] As a further description of the above technical solution, the second end of the cannula body is welded to the connector, and the circuit tube of the respiratory anesthesia machine is plugged into the connector.

[0011] As a further description of the above technical solution, the material of the cannula body is polyvinyl chloride or silicone.

[0012] As a further description of the above technical solution, the pressure sensing device is connected to the air intake pipeline.

[0013] As a further description of the above technical solution, a one-way valve is also provided on the air intake pipeline.

[0014] As a further description of the above technical solution, the cannula body is a transparent tube body provided with length scale marks along the length direction.

[0015] As a further description of the above technical solution, before intubating the animal, local anesthetic is applied on the outer wall of the airbag to the first end of the intubation body.

[0016] As a further description of the above technical solution, the local anesthetic includes but is not limited to lidocaine.

[0017] As a further description of the above technical solution, it also includes an inner core sleeved in the tubular cavity of the cannula body, and the inner core includes at least a straight extension section extending from the first end to the second end of the cannula body.

[0018] By means of the above technical solutions, the outstanding effects of the present invention are:

[0019] 1. The endotracheal tube for animals provided by the present invention, which is compatible with a respiratory anesthesia machine, includes a tube body with a diameter that is at least 1 / 3 smaller than conventional endotracheal tubes in the prior art, while its length is increased by 1 / 4. The tube is long enough to extend from the animal's mouth to the glottis, and its small diameter is less likely to irritate the area near the animal's glottis and avoid causing edema near the animal's glottis. This makes endotracheal intubation of large animals easier, shortens intubation time, and prevents suffocation.

[0020] 2. The airbag located on the outer circumferential wall near the first end of the cannula body is still connected to the pressure sensing device. However, the outside of the inflation connecting tube connecting the airbag and the pressure sensing device is wrapped with a layer of metal mesh, which effectively prevents the intubation tube from being worn off by the animal's teeth during the intubation process, ensuring the effectiveness of the intubation and continuously assisting the animal's breathing and mechanical ventilation.

[0021] 3. The second end of the cannula body is directly welded to the joint and then plugged into the circuit pipe of the respiratory anesthesia machine, thereby preventing the cannula body and the circuit pipe of the respiratory anesthesia machine from being easily disconnected.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following describes the implementation of the present invention based on its overall structure.

[0028] See also Figures 1 to 2The utility model discloses an animal tracheal intubation tube for use with a matching respiratory anesthesia machine. The animal tracheal intubation tube for use with a matching respiratory anesthesia machine comprises:

[0029] The cannula body 1 has a diameter of 6F and a length of 40 cm.

[0030] The airbag 2 is arranged on the circumferential outer wall adjacent to the first end of the cannula body 1. The airbag 2 is connected to the pressure sensing device 4 through an inflation connecting tube 3; the outside of the inflation connecting tube 3 is wrapped with a layer of metal wire mesh 5.

[0031] In the above-mentioned setting, the animal tracheal intubation tube of the supporting respiratory anesthesia machine includes a tube body 1 with a tube diameter of about 6F and a length of about 40 cm. Compared with the conventional tracheal intubation tube in the prior art (the tube diameter is generally 9F, 10F or 11F and the length is 32 cm), the tube diameter is at least reduced by 1 / 3, and the length is increased by 1 / 4. The tube length is sufficient to extend from the animal's mouth to the glottis, and its small diameter is not easy to stimulate the vicinity of the animal's glottis and avoid causing edema near the animal's glottis, making tracheal intubation of large animals easier to perform, shortening the intubation time and avoiding animal suffocation; and the air bag 2 provided on the circumferential outer wall near the first end of the intubation tube body 1 is still connected to the pressure sensing device 4. The difference is that the outer surface of the inflation connecting tube 3 connecting the air bag 2 and the pressure sensing device 4 is wrapped with a layer of metal wire mesh 5, which also effectively prevents it from being worn off by the animal's teeth during the intubation process, ensuring the effectiveness of the intubation, so that it can continue to play the role of assisting animal breathing and mechanical ventilation.

[0032] See also Figure 1 Specifically, in this embodiment, the first end of the cannula body 1 is defined as being located below the second end thereof, and the second end thereof is located above the first end thereof. The second end of the cannula body 1 can be connected to a respiratory anesthesia machine via a connector 6. The connector 6 is, for example, a 15 mm standard connector 6. More specifically, the second end of the cannula body 1 is welded to the connector 6, and the circuit tube of the respiratory anesthesia machine is plugged into the connector 6. The second end of the cannula body 1 is directly welded to the connector 6, thereby preventing the cannula body 1 from easily falling off.

[0033] Specifically, in this embodiment, the material of the cannula body 1 is polyvinyl chloride. Of course, in other embodiments, the material of the cannula body 1 can also be silicone.

[0034] See also Figure 1Specifically, in this embodiment, the pressure sensing device 4 is connected to the air intake pipe (not shown in the figure) to monitor the pressure of the gas delivered to the air bag 2 by the air intake pipe, so as to prevent the air bag 2 from excessively inflating and compressing the animal's trachea. More specifically, a one-way valve 7 is also provided on the air intake pipe to ensure the direction of gas delivery. Figure 2 As shown, it should be understood that the metal mesh 5 wrapped around the outside of the inflation connecting tube 3 connecting the airbag 2 and the pressure sensing device 4 should be made of metal that meets the medical device grade.

[0035] Specifically, in this embodiment, the cannula body 1 is a transparent tube with length scale markings 8 along its length to facilitate monitoring of the respiratory tract surrounding the cannula body 1 during intubation. The length scale markings 8 include a prominent marking line adjacent to the airbag 2 to indicate the insertion depth of the cannula body 1 into the trachea (e.g., indicating that the first end of the cannula body 1 has passed the animal's glottis and entered the upper trachea).

[0036] Specifically, in this embodiment, before intubation of an animal, a local anesthetic is applied to the outer wall of the airbag 2 extending from the first end of the cannula body 1, thereby effectively preventing glottic edema caused by intubation. More specifically, the local anesthetic may be, but is not limited to, lidocaine.

[0037] Specifically, in this embodiment, the animal endotracheal tube for use with a respiratory anesthesia machine further includes an inner core (not shown) sheathed within the lumen of the tube body 1. The inner core includes a linear extension extending from a first end to a second end of the tube body 1, thereby ensuring that the endotracheal tube is more suitable for the oral cavity, pharynx, and trachea, which are substantially aligned in the same longitudinal direction when the animal is in the supine position. Of course, in other embodiments, the inner core may also be an entirely straight extension.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any changes, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
