Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and more particularly to a threaded anti-slip chest tube with a needle. Background Art
[0002] Pneumothorax is caused by the rupture of lung tissue and visceral pleura, which causes air to enter the pleural cavity, resulting in pleural gas accumulation and lung shrinkage. When the air causes lung compression, it can pull the adhesion band, causing it to tear, and the small arteries in the adhesion band to rupture and bleed. At this time, closed chest drainage is the most timely and effective treatment method. After the tube is placed, there is no gas escape, and the patient has no breathing difficulties. The tube needs to be clamped for observation for 48-72 hours. If the chest X-ray shows that the lung has re-expanded, the tube can be removed.
[0003] A chest tube with a needle is a commonly used medical auxiliary device in clinical practice. It consists of a chest tube and a guide needle. It is mainly used to treat pneumothorax, hemothorax, empyema or other pleural effusions. When in use, the doctor needs to insert the chest tube with a needle into the patient's pleural cavity through surgery to drain the gas, liquid or pus in the pleural cavity; at the same time, the guide needle is used to guide and assist in the insertion of the catheter.
[0004] At present, after the placement and removal of the needle, the chest tube is generally fixed with tape. However, the tape fixation is not stable enough. When the patient turns over and moves, the connector and the catheter are easily displaced and rotated. Since the upper section of the chest tube with a needle is thinner and the surface is relatively smooth, the catheter is easily shaken and fallen off due to the movement of the connector after being connected to the drainage bottle; this will cause subcutaneous emphysema in the patient and even cause the patient's death.
[0005] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the invention
[0006] The purpose of the present invention is to provide a threaded anti-slip chest tube with a needle, which makes the chest tube less likely to shake and fall off, thereby improving safety.
[0007] The present invention provides a threaded anti-slip chest tube with a needle, comprising a chest tube, a guide needle, an anti-slip device and a connecting device; the connecting device is fixedly sleeved on the side of the chest tube, the cross-section of the connecting device is an isosceles trapezoid, an external thread is arranged on the side of the connecting device, and the guide needle is inserted into the chest tube; the anti-slip device comprises a fixing plate and a connecting part, the connecting part is connected to the middle part of the fixing plate, a conical hole matching with the connecting device is arranged on the connecting part, an internal thread matching with the external thread is arranged on the inner wall of the conical hole, suture locking openings are arranged on both sides of the connecting part on the fixing plate; and binding strap connecting openings are arranged at both ends of the fixing plate.
[0008] By adopting the above technical scheme, after the threaded anti-slipping needle chest tube is inserted into the pleural cavity, the guide needle is pulled out, and the tail end of the chest tube is sealed by the closure cap, thereby effectively preventing the pleural cavity from being connected to the outside world; at this time, the fixing plate is attached to the puncture hole on the chest, and the ends of the sutures for suturing the wound on both sides of the puncture hole are wrapped and fixed on the suture locking port; at the same time, the strap connection ports at both ends of the fixing plate are connected with straps, and the fixing plate is tied to the patient's chest through the straps, and the straps at both ends of the fixing plate are fixed at the patient's back; the anti-slipping device is fixed by the sutures for suturing the wound for the first layer, and the straps are fixed for the second layer; thus, the chest tube connected to the anti-slipping device is not easy to shake or fall off, thereby improving safety. In addition, the connection device with an isosceles trapezoidal cross-section and the tapered hole are designed to make the thread tight and not easy to shake; on the other hand, opening the closure cap can easily establish a channel connecting the pleural cavity with the outside world, and a series of clinical operations such as injection, flushing, and retaining pathogen specimens can be performed using this channel.
[0009] Furthermore, side holes are provided on the chest tube at 1 cm, 2 cm and 3 cm away from the head end of the chest tube.
[0010] Furthermore, the side hole is a waist-shaped hole.
[0011] Furthermore, the angles between the side holes located at 1 cm, 2 cm and 3 cm from the head end of the chest tube in a top view are 120 degrees.
[0012] Furthermore, the length of the chest tube is 21cm-25cm.
[0013] The threaded anti-slipping chest tube with needle of the present invention is inserted into the pleural cavity, and the guide needle is pulled out, and the tail end of the chest tube is sealed by the closure cap, thereby effectively preventing the pleural cavity from being connected to the outside world; at this time, the fixing plate is attached to the puncture hole of the chest, and the ends of the sutures for suturing the wound on both sides of the puncture hole are wound and fixed on the suture locking mouth; at the same time, the strap connection ports at both ends of the fixing plate are connected with straps, and the fixing plate is tied to the patient's chest by the straps, and the straps at both ends of the fixing plate are fixed at the patient's back; the anti-slipping device is fixed by the sutures for suturing the wound for the first layer, and the second layer is fixed by the straps; thereby, the chest tube connected to the anti-slipping device is not easy to shake and fall off, thereby improving safety. In addition, the connection device with an isosceles trapezoidal cross section and the tapered hole are designed to make the thread tight and not easy to shake; on the other hand, the closure cap can be opened to easily establish a channel connecting the pleural cavity with the outside world, and a series of clinical operations such as injection, flushing, and retaining pathogen specimens can be performed using this channel.
