[0022] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Such as Figure 1 , Figure 2As shown in the figure, this embodiment provides a thoracic drainage device with an analgesic effect, including: a first tube body 1, which can be a plastic tube. During use, the distal end of the first tube body 1 extends into the thoracic cavity, and the proximal end of the first tube body 1 is connected to a fluid collection device 9. The fluid in the thoracic cavity can flow into the fluid collection device 9 along the first tube body 1. For example, the fluid collection device 9 can be a drainage bottle with a suction function to make it easier for the fluid to drain out. A second tube body 2, which can be a plastic tube. For example, the second tube body 2 can be adhesively bonded to the inner wall of the first tube body 1 and is located inside the first tube body 1, and both ends of the second tube body 2 extend outwards from inside the first tube body 1; an analgesic pump 3, which is connected to the proximal end of the second tube body 2 and is used to deliver pain-relieving drugs into the second tube body 2. The pain-relieving drugs can be local anesthetics, morphine, etc.; among them, the analgesic pump 3 can select a conventional 48-hour pump, prepare an analgesic drug including local anesthetics, morphine, etc., and then connect it to the second tube body 2 through a connector. When pumping the drug, the conventional uniform speed can be set at 2 ml / h, or it can be self-controlled for drug delivery at any time according to the severity of the patient's pain. The self-controlled drug delivery can be 0.5 ml / time, and the self-control interval is 15 minutes. As the drug decreases, the expansion bladder of the analgesic pump 3 will gradually shrink until it is completely deflated, indicating that the drug has been used up. A release device 4, which is arranged at the distal end of the second tube body 2. For example, the release device 4 can be adhesively bonded or integrally formed on the second tube body 2. During use, the release device 4 is in contact with the pleura; the release device 4 includes a drug storage cavity 5 and micro needles 6. The drug storage cavity 5 is connected to the second tube body 2. Each time the analgesic pump 3 delivers drugs, the drugs can be temporarily stored in the drug storage cavity 5 first. The micro needles 6 are arranged on the drug storage cavity 5. The internal cavity of the micro needles 6 is connected to the drug storage cavity 5, and micropores are arranged on the surface of the micro needles 6. During use, the micro needles 6 can pierce into the pleura, and the pain-relieving drugs in the drug storage cavity 5 are continuously and slowly released to the pleura through the micropores on the micro needles 6. According to the severity of the pain, this self-controlled or continuous uniform drug delivery method can reduce the patient's pain, more accurately control the drug dosage, reduce the risk of medication, and can also be self-controlled for drug delivery at any time, making the medication more scientific.

[0024] Among them, in this application, the proximal end refers to the end far from the patient's body, and the distal end refers to the end close to the patient. For example, the distal end of the first tube body 1 refers to the end of the first tube body 1 that extends into the patient's body. Similarly, the distal end of the second tube body 2 refers to the end of the second tube body 2 that extends into the patient's body.

[0025] The thoracic drainage device with an analgesic effect provided by this embodiment has a second tube body 2 arranged inside the first tube body 1. The first tube body 1 is used to drain fluid, and the second tube body 2 is used to deliver pain-relieving drugs. Moreover, a release device 4 is arranged at the distal end of the second tube body 2. The pain-relieving drugs in the drug storage cavity 5 are released to the pleura by using the micro needles 6 in a self-controlled or continuous uniform manner according to the severity of the pain. While draining the thoracic cavity, it can also reduce the patient's pain, which is beneficial to the patient's treatment and recovery.

[0026] Among them, a plurality of liquid inlet holes 7 are provided on the side wall of the first tube body 1, so that the effusion in the thoracic cavity can enter the first tube body 1 through the liquid inlet holes 7. For example, a single row or multiple rows of liquid inlet holes 7 can be provided on the side wall of the first tube body 1 to improve the effusion discharge effect. For example, the liquid inlet holes 7 are all provided on the lower half tube section of the first tube body 1. With this setting, there are no liquid inlet holes 7 on the tube section of the first tube body 1 located outside the patient's thoracic cavity, preventing external air from entering.

[0027] Among them, at least a section of the distal end of the first tube body 1 is a soft silicone tube section 8. For example, a section of soft silicone tube section 8 with a length of 1 cm - 3 cm can be provided at the distal end of the first tube body 1 to reduce the damage of the first tube body 1 to the tissues in the thoracic cavity and relieve the discomfort of the patient.

[0028] Among them, there are multiple microneedles 6, and the microneedles 6 are all arranged at the bottom of the medicine storage cavity 5. For example, the microneedles 6 can be bionic microneedles 6 containing silk fibroin and poly, the diameter range of the microneedles 6 can be 10 nm - 500 nm, and nano-scale micropores or pits are provided on the surface of the microneedles 6.

[0029] Among them, the diameter range of the first tube body 1 is 10 mm - 11 mm, and the length of the first tube body 1 can be 45 cm.

[0030] Among them, the diameter range of the second tube body 2 is 0.4 mm - 0.8 mm.

[0031] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
