Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, and specifically relates to a chest drainage tube. Background Art

[0002] Currently, in addition to lung leakage caused by lung quality problems and surgical suturing techniques, there are also undetected leaks due to small damage in some drainage tubes, which will lead to pneumothorax in patients.

[0003] Current status of drainage tubes: chest tubes are often slightly damaged due to operation or external reasons and cannot be discovered. Small air leaks caused by loose sutures of the chest drainage tube openings cannot be discovered. When air leaks are discovered in the drainage tubes, the entire chest bottle or the entire device is directly replaced, which increases the patient's hospitalization time, increases the patient's economic burden, and increases the risk of infection. Therefore, a chest drainage tube is proposed that can prevent pneumothorax from occurring after air leaks in the drainage tube and can detect air leaks in time.

[0004] In addition, on the one hand, there are differences in understanding among technical personnel in this field; on the other hand, the utility model inventor studied a large number of documents and patents when making the utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the utility model does not have the characteristics of these prior arts. On the contrary, the utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0005] The purpose of the utility model is to provide a chest drainage tube to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chest drainage tube, comprising a drainage tube body, a protective film is arranged inside the drainage tube body, which is used to provide protection after the drainage tube body leaks, a chamber is formed between the drainage tube body and the protective film, the chamber is in a negative pressure state and is in contact with the inner wall of the drainage tube body, and a monitoring component for identifying air leakage is installed on the outer wall of the drainage tube body.

[0007] Preferably, the monitoring component includes a connecting tube, which is installed on the drainage tube body and connected to the chamber. A sealing tube is installed at the end of the connecting tube. Both the sealing tube and the connecting tube are in a negative pressure state, and a sealing plug is provided in the sealing tube to separate it into two parts.

[0008] Preferably, the connecting tube connected to the sealing tube and the space of the chamber form a first negative pressure chamber, and the space on the other side of the sealing tube corresponding to the sealing plug forms a second negative pressure chamber.

[0009] Preferably, the negative pressure in the first negative pressure chamber and the second negative pressure chamber is the same. When the drainage tube body leaks, gas rushes into the chamber, increasing the pressure in the second negative pressure chamber, causing the sealing plug to move under the suction of the first negative pressure chamber, thereby measuring the leakage of the drainage tube body.

[0010] Preferably, an identification line is provided on the outer side wall of the sealing tube corresponding to the sealing plug.

[0011] Compared with the prior art, the beneficial effects of the utility model are: a chest drainage tube, which protects the drainage tube body without affecting the use of the drainage tube body by setting the chamber to a negative pressure state. If there is a leak in the drainage tube body, the gas enters the chamber and will not directly enter the internal channel of the drainage tube body, thereby avoiding pneumothorax, increasing the safety of the patient, and reducing the replacement of the entire chest bottle or the entire set of equipment, thereby reducing the patient's economic burden and infection risk. Through the set monitoring component, it is possible to monitor whether the drainage tube body has a leak. If a leak occurs, the leaking part can be dealt with in time.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 The utility model provides a technical solution: a chest drainage tube, comprising a drainage tube body 1, a protective film 2 is arranged inside the drainage tube body 1, which is used to form a protection after the drainage tube body 1 leaks, a chamber 3 is formed between the drainage tube body 1 and the protective film 2, the chamber 3 is in a negative pressure state and fits with the inner wall of the drainage tube body 1, and the outer wall of the drainage tube body 1 is installed with a monitoring component for identifying air leakage.

[0017] Specifically, the monitoring component includes a connecting tube 4, which is installed on the drainage tube body 1 and connected to the chamber 3. A sealing tube 5 is installed at the end of the connecting tube 4. The sealing tube 5 and the connecting tube 4 are both in a negative pressure state, and a sealing plug 6 is provided in the sealing tube 5 to separate it into two parts.

[0018] Specifically, the connecting tube 4 connected to the sealing tube 5 and the space of the chamber 3 form a first negative pressure chamber 7, and the space on the other side of the sealing tube 5 corresponding to the sealing plug 6 forms a second negative pressure chamber 8.

[0019] Specifically, the negative pressures in the first negative pressure chamber 7 and the second negative pressure chamber 8 are the same. When the drainage tube body 1 leaks, gas rushes into the chamber 3, increasing the pressure in the second negative pressure chamber 8, causing the sealing plug 6 to move under the suction of the first negative pressure chamber 7, thereby measuring the leakage of the drainage tube body 1.

[0020] Specifically, a marking line 9 is provided on the outer wall of the sealing tube 5 corresponding to the sealing plug 6 .

[0021] The sealing tube 5 is made of a transparent hard material, and the position change of the sealing plug 6 can be observed from the outside to confirm whether the drainage tube body 1 is leaking.

[0022] The width of the identification line 9 is the same as the width of the sealing plug 6 , and the edge of the identification line 9 coincides with the edge of the sealing plug 6 .

[0023] Working principle: When the utility model is used, the negative pressures in the first negative pressure chamber 7 and the second negative pressure chamber 8 are the same. When the drainage tube body 1 leaks, the protective film 2 blocks the gas from entering the internal pipeline of the drainage tube body 1 to prevent the patient from having pneumothorax. Due to the leakage of the drainage tube body 1, the gas enters the chamber 3 from the leaking part, and the pressure in the second negative pressure chamber 8 increases. The pressure in the first negative pressure chamber 7 is lower than the pressure in the second negative pressure chamber 8. The first negative pressure chamber 7 adsorbs the sealing plug 6 to make it close to the first negative pressure chamber 7. The sealing plug 6 is separated from the initial position, and the sealing tube 5 is misaligned with the marking line 9, confirming that the drainage tube body 1 is leaking.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
