Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an intrabronchial oxygen supply catheter. Background Art

[0002] An oxygen supply catheter is a medical device primarily used to provide oxygen to patients. It comes in a variety of forms, including catheters, plugs, and simple masks, to meet the needs of different patients. A nasal cannula is the most commonly used low-flow oxygen delivery method. Inserting the catheter deep into the nasal cavity ensures smooth oxygen delivery. In clinical practice, endotracheal intubation is a fundamental skill used for patients undergoing general anesthesia, critically ill patients, and for cardiopulmonary resuscitation in patients with cardiac and respiratory arrest.

[0003] In the Chinese patent publication number CN203379450U, an intrabronchial oxygen supply catheter is mentioned. It has a simple structure and is easy to use. It can greatly reduce the dead space volume and repeated inhalation volume of lung tissue, significantly reduce respiratory resistance, improve the safety of anesthesia and the success rate of resuscitation, and ensure the medical safety of patients. It is an ideal intrabronchial oxygen supply catheter.

[0004] The above-mentioned intrabronchial oxygen supply catheter in the prior art is prone to causing damage to the patient's trachea when it is pulled out after use due to the lack of lubrication on the outer side of the catheter. In addition, the catheter is not fixed during use and is prone to displacement. Therefore, we propose an intrabronchial oxygen supply catheter. Utility Model Content

[0005] The utility model aims to provide an intrabronchial oxygen supply catheter to solve the problems in the prior art of lack of lubrication when pulled out, easy damage to the patient's trachea, and lack of fixation of the catheter during use.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An intrabronchial oxygen supply catheter comprises a catheter body, a connector provided at the top end of the catheter body, two symmetrically distributed ties provided on the outside of the connector, a water injection balloon provided at the lower outside of the catheter body, a liquid outlet hole provided on the outside of the water injection balloon, an injection tube fixedly connected to the inside of the liquid outlet hole, a conical head provided at the bottom end of the catheter body, and a syringe provided on the outside of the catheter body.

[0008] Preferably, a depth scale is provided on the outside of the catheter body.

[0009] Preferably, a balloon connecting tube extending into the interior of the catheter body is provided on the outside of the catheter body, and the other end of the balloon connecting tube is connected to the interior of the water-injected balloon.

[0010] Preferably, a suction tube extending into the interior of the catheter body is provided on the outside of the catheter body, and adapters are provided on the top end of the suction tube and the top end of the balloon connecting tube.

[0011] Preferably, a suction hole is provided on the outside of the catheter body, and the bottom end of the suction tube is communicated with the inside of the suction hole.

[0012] Preferably, the other end of the injection tube passes through the catheter body and extends outside the catheter body, and is connected to the output end of the syringe.

[0013] Preferably, a through hole is provided on the outer side of the connector, and a round block is fixedly connected to one end of the lace.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model is provided with an injection tube, a syringe and a liquid outlet. When in use, a lubricant can be injected into the outside of the water injection balloon through the syringe and the injection tube. Under the action of the lubricant, the water injection balloon and the outside of the catheter body are lubricated, reducing friction with the inner wall of the trachea, preventing damage to the patient during withdrawal or insertion, and has good practicality.

[0016] 2. The utility model is provided with a lacing, a round block and a round hole. When in use, the lacing can fix the catheter body at the position of the patient's mouth.

[0024] In a further embodiment, referring to Figure 1 and Figure 3 A depth scale 2 is provided on the outside of the catheter body 1. The depth scale 2 can obtain the insertion depth of the catheter body 1, so as to facilitate the insertion of the catheter body 1 according to the actual situation of the patient. The other end of the injection tube 12 passes through the catheter body 1 and extends outside the catheter body 1, and is connected to the output end of the syringe 13. Lubricant can be injected into the injection hole through the syringe 13 and the injection tube to improve the lubrication effect.

[0025] In this embodiment, lubrication is performed when the catheter body 1 is inserted into the patient's body or when the catheter body 1 is pulled out of the patient's body, thereby avoiding damage to the patient's trachea.

[0026] In a further embodiment, referring to Figure 1-Figure 3 A balloon connecting tube 5 extending into the interior of the catheter body 1 is provided on the outside of the catheter body 1. The balloon connecting tube 5 can inject water into the water-injected balloon 3, which is convenient for fixing the catheter body 1 inside the trachea. When pulling out, the water in the water-injected balloon 3 is extracted to reduce the volume of the water-injected balloon 3, which is convenient for pulling out and inserting. The other end of the balloon connecting tube 5 is connected to the inside of the water-injected balloon 3.

[0027] In this embodiment, water can be injected into or extracted from the water-injection balloon 3 through the balloon connecting tube 5 , thereby facilitating the fixation of the catheter body 1 and the insertion or removal of the catheter body 1 into or from the patient's body.

[0028] In a further embodiment, referring to Figure 1-Figure 3 A suction tube 6 extending into the interior of the catheter body 1 is provided on the outside of the catheter body 1. The suction tube 6 can be connected to a suction device to extract the accumulated fluid above the water-injected balloon 3 through the suction hole 9 to avoid causing discomfort to the patient. An adapter 11 is provided at the top of the suction tube 6 and the top of the balloon connecting tube 5.

[0032] The working principle of this utility model is as follows:

[0033] When the catheter body 1 is in use, lubricating liquid is injected into the injection hole through the syringe 13 and the injection tube 12. The lubricating liquid flows through the injection hole to the outside of the water injection balloon 3, and then flows through the water injection balloon 3 to the outside of the catheter body 1 and the tapered head 4 below. It lubricates the catheter body 1 when it is inserted or removed, thereby reducing friction on the patient's trachea.

[0034] After the catheter body 1 is inserted, the catheter body 1 is fixed to the patient's head by two ties 8 to prevent the catheter body 1 from moving. When the ties 8 are no longer needed, the ties 8 are removed from the round hole.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
