Description

Technical Field

[0001] The utility model relates to a sputum aspirator tube, in particular to a visual sputum aspirator tube with a peelable protective film. Background Art

[0002] Currently, the commonly used sputum aspirator tube is a set of sterile packaging, including two sterile plastic gloves and a single-layer sputum aspirator tube. However, from the actual clinical operation process, we found that such a packaging design is not very reasonable and convenient for a single person to operate, and it also cannot guarantee absolute sterility. Because when both hands are wearing the sterile plastic gloves in the sputum aspiration kit, whether it is opening the lid of the sputum aspiration port of the tracheal catheter, or disinfecting the opened lid of the sputum aspiration port of the tracheal catheter with a cotton ball, or connecting the tail of the sputum aspirator tube to a negative pressure suction device, etc., these operations may lose the protective effect of wearing these sterile gloves.

[0003] But in the sputum aspiration operation, the aseptic operation standard should be achieved to avoid increasing the risk of iatrogenic pulmonary infection. Taking a single-person operation as an example: it is necessary to wear another pair of sterile gloves in advance, and then wear the pair of sterile plastic gloves in the sputum aspirator tube packaging. If a non-sterile object is touched, the contaminated gloves need to be removed, or keep one hand continuously holding the sputum aspirator tube and require the assistance of another colleague. For example, another colleague is required to open the lid of the sputum aspiration port of the tracheal catheter, disinfect the opened tracheal catheter opening with a cotton ball, and connect the tail of the sputum aspirator tube to a negative pressure suction device, etc.

[0004] In addition, after the sputum aspirator tube enters the endotracheal tube, it is a blind operation. Due to the fixed length of the sputum aspirator tube and the body type differences of different patients, the softer sputum aspirator tube is easily guided or interfered by the shape of the endotracheal tube and is likely to poke the same position of the tracheal intima. Repeated sputum aspiration operations for a long time are likely to cause airway intima damage and are not easily detected. Content of the Utility Model

[0005] The utility model provides a visual sputum aspirator tube with a peelable protective film. The sputum aspirator tube includes a sputum aspirator tube main body, and a protective film completely covers the surface of the sputum aspirator tube main body. The length of the protective film is greater than the length of the sputum aspirator tube main body. The protective film is provided with two parallel slits distributed along the length direction of the sputum aspirator tube main body. An easy-to-tear strip is formed between the two slits. One end of the easy-to-tear strip extends beyond the rear end of the sputum aspirator tube main body. Tear off the easy-to-tear strip to tear the protective film upward from bottom to expose the sputum aspirator tube main body;

[0006] The front end of the sputum aspirator tube main body is sequentially communicated with a transparent sleeve and a negative pressure joint;

[0007] A visual guide wire unit is provided inside the sputum suction tube. The visual guide wire unit consists of a guide wire, a lens and a micro display screen connected to both ends of the guide wire. The micro display screen is built-in with a power supply. The lens is close to the rear end opening of the sputum suction tube body. A rectangular window is provided on the side wall of the transparent sleeve, and the micro display screen is installed inside the rectangular window.

[0008] Further, the negative pressure connector is a taper connector.

[0009] Further, the lens is 3 cm away from the rear end opening of the sputum suction tube body.

[0010] Further, the material of the negative pressure connector is silicone.

[0011] The advantages of the present utility model are as follows:

[0012] 1. By providing a peelable protective film on the surface of the sputum suction tube, the sterility of the sputum suction tube before use is ensured, and the risk of contamination caused by multiple contacts with non-sterile items during the operation is avoided.

[0013] 2. The easy-to-tear strip design on the protective film makes the single-person operation simple and convenient, without the need to wear multiple pairs of gloves additionally, improving the operation efficiency and reducing the possibility of cross-infection at the same time.

[0014] 3. The setting of the visual guide wire unit enables real-time observation of the position and state of the sputum suction tube in the trachea when the sputum suction tube enters the endotracheal tube, avoiding the risk of airway intima injury caused by blind operation.

[0015] 4. The design of the transparent sleeve and the negative pressure connector makes the connection and use of the sputum suction tube more convenient. At the same time, the use of the taper connector improves the connection stability and sealing performance.

[0016] 5. The combination of the micro display screen and the lens enables medical staff to directly see the position of the sputum suction tube in the trachea, so as to perform sputum suction operation more accurately and reduce the injury to the airway.

[0017] In summary, the visual sputum suction tube of the present utility model not only improves the safety and convenience of clinical operation, but also significantly reduces the risk of iatrogenic pulmonary infection through the application of visual technology, and improves the accuracy and efficiency of sputum suction operation.

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] In order to thoroughly understand the present utility model, detailed steps and detailed structures will be presented in the following description to explain the technical solution of the present utility model. The preferred embodiments of the present utility model are described in detail as follows. However, in addition to these detailed descriptions, the present utility model can also have other implementation manners.

[0025] Referring to Figure 1-2 As shown, the present utility model provides a visual suction catheter with a peelable protective film. The suction catheter includes a suction catheter main body 10. The suction catheter main body 10 is drawn in an omitted manner, and the actual length can be adjusted according to requirements. The surface of the suction catheter main body 10 is completely coated with a protective film 20. The length of the protective film 20 is greater than the length of the suction catheter main body 10. The protective film 20 is provided with two parallel slits 21 distributed along the length direction of the suction catheter main body 10. An easy-to-tear strip 22 is formed between the two slits 21. One end of the easy-to-tear strip 22 extends beyond the rear end of the suction catheter main body 10 to form a handle 23 at the tail of the easy-to-tear strip 22 for easy tearing.

[0026] The front end of the suction catheter main body 10 is sequentially connected to a transparent sleeve 30 and a negative pressure connector 40. The negative pressure connector 40 is used to connect a negative pressure device. The negative pressure connector 40 is a silicone pagoda connector, which improves the sealing performance of the connection with the negative pressure device.

[0027] As Figure 3-4As shown, a visualization guide wire unit 50 is provided in the suction tube. The visualization guide wire unit 50 consists of a guide wire 51 and a lens 52 and a micro display screen 53 connected at both ends of the guide wire 51. The micro display screen 53 has a built-in power supply. The lens 52 is 3 cm close to the rear end opening of the suction tube body 10. A rectangular window 31 is integrally formed on the side wall of the transparent sleeve 30, and there is no gap on the outer wall of the transparent sleeve 30. A micro display screen 53 is installed on the inner side of the rectangular window 31.

[0028] This method can ensure that the suction tube body 10 is always in a sterile state. When the human hand is pulling open the suction tube body 10, the hand does not touch the suction tube body 10. The specific operation steps are: pinch the protective film 20 or the joint part on the surface of the suction tube body 10 with one hand, and tear off the easy-tear strip 22 with the other hand through the handle 23 to first tear off a part of the bottom of the protective film 20, expose the bottom of the suction tube body 10 and insert the bottom of the suction tube body 10 into the tracheal tube, and then continue to tear the easy-tear strip 22 upwards while slowly inserting the suction tube body 10 into the tracheal tube until the insertion is completed. The utility model is easy to operate and use. A single person can hold the outer sterile protective film 20 to maintain the sterile state of the internal suction tube body 10, effectively avoiding the risk of exogenous contamination entering the patient's trachea and causing nosocomial lung infection.

[0029] In addition, a soft visualization guide wire unit 50 is added to the inner side of the suction tube body 10, and the micro display screen 53 of the visualization guide wire unit 50 is arranged at the handle of the suction tube (i.e., the transparent sleeve 30), and the lens 52 of the visualization accessory is arranged 3 cm away from the tail of the suction tube body 10. During the suction process, the free position of the front end of the suction tube body 10 can be observed by observing the micro display screen 53 to avoid damaging the airway lining and detect damage to the airway lining as early as possible.

[0030] The above describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the above-mentioned specific implementation methods, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the utility model without departing from the scope of the technical solution of the utility model, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of protection of the technical solution of the utility model.
