Description

Technical Field

[0001] The utility model relates to a chest pain relief drainage tube, belonging to the technical field of medical equipment. Background Art

[0002] Closed thoracic drainage involves placing one end of a drainage tube into the chest cavity and connecting the other end to a water-seal bottle located lower than the tube. This allows for the removal of air or collection of fluid within the chest cavity, allowing the lungs to reopen and restore function. This procedure is widely used as a treatment for hemothorax, pneumothorax, and empyema, as well as after thoracotomy, and plays a crucial role in the treatment of these conditions.

[0003] Placing a closed drainage system requires an incision in the chest wall and inserting a drainage tube into the chest cavity. However, intubation and drainage require penetrating the skin and muscle tissue, which can cause nerve compression or damage, causing pain. This pain is usually sharp, intense, and persistent, and may radiate to surrounding areas. During intubation and drainage, the drainage tube passes through the pleura and lung tissue, which can irritate them and cause discomfort or even pain.

[0004] Currently, in order to reduce the discomfort of patients during drainage, local anesthesia or analgesics are usually given to patients before surgery. However, since the pain here is radioactive and each patient has different sensitivity to anesthetics, local anesthesia and analgesics cannot guarantee to reduce the pain of most patients, and the pain relief effect is poor. Therefore, there is an urgent need for a drainage tube that can provide anesthetics at any time during surgery to reduce the pain and discomfort of patients. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to alleviate the pain and discomfort of most patients during chest drainage and improve the pain reduction effect.

[0006] In order to solve the above technical problems, the utility model provides a chest pain-relieving drainage tube, which can replenish anesthetics at any time during the drainage process of the drainage tube to relieve the patient's pain and discomfort.

[0007] To achieve the above technical objectives and effects, this application is implemented through the following technical solutions:

[0008] A chest pain relief drainage tube includes a drainage tube body, a plurality of drainage holes are opened on the outer wall of one end of the drainage tube body, at least one drug delivery tube is provided on the drainage tube body, one end of the drug delivery tube extends out of the outer wall of the drainage tube body at one end with the drainage holes, and the other end of the drug delivery tube extends out of the outer wall of the drainage tube body at one end away from the drainage holes and is connected to a drug delivery component, wherein the drug delivery component is used to deliver anesthetic into the drug delivery tube.

[0009] Preferably, the drug delivery component includes an extrusion airbag and a one-way valve, the extrusion airbag is connected to the drug delivery tube through the one-way valve, and the extrusion airbag is filled with anesthetic.

[0010] Furthermore, a medicine replenishing port is provided on the side wall of the extruded airbag, and a sealing cover is threadedly connected to the medicine replenishing port.

[0011] Preferably, two dosing tubes are provided and are evenly spaced around the circumference of the drainage tube body. The ends of the two dosing tubes facing away from the drainage tube are connected through a ring tube, and the dosing assembly is connected to the ring tube.

[0012] Preferably, one end of the drainage tube body where the drainage hole is provided is rounded.

[0013] The utility model provides a chest pain relief drainage tube, which has the following advantages:

[0014] The chest pain-relieving drainage tube of the present invention is provided with multiple drug delivery tubes on the drainage tube body and connected to the drug delivery components. When the drainage tube is inserted into the human chest cavity for drainage operation, if the patient feels discomfort and pain, the surgeon can press and squeeze the airbag so that the anesthetic in the squeezed airbag passes into the affected part of the human body through the drug delivery tube, thereby achieving pain relief. The drug delivery operation can be started or stopped at any time, which is convenient and quick, thereby alleviating the patient's pain and discomfort from the source as much as possible.

[0020] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts are within the scope of protection of this utility model.

[0021] Reference Figure 1-Figure 3 A chest pain-relieving drainage tube includes a drainage tube body 1, which is a cylindrical tube and has a plurality of drainage holes 11 integrally injection-molded on the outer wall at one end. The arrangement of the drainage holes 11 can minimize the possibility of blockage during the drainage process of the drainage tube body 1, and the end of the drainage tube body 1 provided with the drainage holes 11 is inverted with a rounded corner to facilitate the insertion of the drainage tube body 1; at least one drug delivery tube 2 is installed on the drainage tube body 1, one end of the drug delivery tube 2 extends out of the outer wall of the drainage tube body 1 at one end provided with the drainage holes 11, and the other end of the drug delivery tube 2 extends out of the outer wall of the drainage tube body 1 at one end away from the drainage holes 11 and is connected to a drug delivery component 3, which is used to deliver anesthetics into the drug delivery tube 2, so that the anesthetics directly act on the affected area to achieve pain relief.

[0022] Furthermore, the dosing component 3 includes an extrusion airbag 31 and a one-way valve 32. The extrusion airbag 31 is connected to the dosing tube 2 through the one-way valve 32.
