Problems solved by technology

[0003] However, the medicine thread commonly used in clinical practice is often inserted into the lumen, and the end of the medicine thread protruding out of the body is fixed with adhesive tape. The patient rubs repeatedly due to movement, causing the tape to easily detach from the skin, causing the medicine thread to fall off.
For larger and deep cavities, the drug thread is easy to fall into the cavity. If it falls too deep, it cannot be taken out with tweezers, and the drug thread will cause foreign body irritation to the affected area and aggravate the infection

Embodiment 1

[0032] Embodiment 1 discloses a specific implementation of a self-fixing drug thread, including: a drug thread 3, a non-absorbable braided thread connected to the tail end of the drug thread 3, the diameter of the non-absorbable braided thread is ≥0.35mm, and is knotted The tensile strength is 21.2N, by limiting the wire diameter of the non-absorbent braided wire and the knotted tensile strength. Avoid when the medicine thread 3 falls into the cavity, when the medicine thread 3 is pulled out with the non-absorbable braided thread, the non-absorbable braided thread is broken due to the excessive force of the non-absorbable braided thread, so that it is impossible to pull out the medicine thread that fell into the cavity. medicine line 3. The parameters of the non-absorbable braided wire are listed in Table 1. The diameter of the non-absorbable braided wire is determined according to the actual situation, preferably

[0033] The selected value is from 0.35mm to 0.399mm, which c...

Embodiment 2

[0041] Such as figure 2 Shown, embodiment 2 is on the basis of embodiment 1, and the medical thread 3 of embodiment 2 is that mulberry paper 1 rubs and forms, and before mulberry paper 1 is rubbed, the non-absorbable braided thread is stretched into mulberry paper 1 for pre-treatment. Assuming a distance, a part of the length of the non-absorbent braided wire remains outside the mulberry paper 1, and this length is a preset length. And setting preset distance is 1 / 3~1 times of the length of mulberry paper 1 before rubbing, and preset length is 3~10cm. The lengths of the non-absorbable braided threads that extend into the mulberry paper 1 and the lengths of the non-absorbable braided threads that stay outside the mulberry paper 1 corresponding to No. 1 to No. 5 drug threads 3 in Example 1 are shown in Table 2 below.

[0042] By kneading a length of non-absorbable braided thread into the medicinal thread 3, the connection strength between the tail end of the medicinal thread 3...

Embodiment 3

[0045] Such as figure 2 As shown, embodiment 3 is based on embodiments 1-2, and the tail end of the medicine wire 3 in embodiment 3 is connected with a medical double-sided adhesive tape 4 .

[0046] Such as figure 1 As shown, before the mulberry paper 1 is rubbed, one end of the non-absorbable braided thread is placed on the surface of the mulberry paper 1, and the non-absorbent braided thread is located at a preset distance on the surface of the mulberry paper 1, and the mulberry paper 1 is rubbed and then folded in half to form Medicinal thread 3, at this time, one end of the non-absorbable braided thread is located in the medicinal thread 3 after rubbing. After rubbing is completed, as figure 2 shown.

[0047] Such as figure 2 As shown, the medical double-sided adhesive tape 4 is pasted on the two ends of the tail of the rubbed medicinal thread 3 near the non-absorbable braided thread, and the bonding area between the medical double-sided adhesive tape 4 and the med...

Abstract

The invention discloses a self-fixing medicated thread, which comprises a medicated thread part and a non-absorbable braided wire which is connected with the tail end of the medicated thread; and whenthe self-fixing medicated thread is in a use state, the front end of the medicated thread part extends into a lesion, and one end, far away from the medicated thread, of the non-absorbable braided wire is arranged out of a human body. A manufacturing method of the self-fixing medicated thread comprises the following steps: S10, mulberry bark paper is spread out and placed, and one end of the non-absorbable braided wire extends into the mulberry bark paper at a preset distance, wherein a length of the non-absorbable braided wire leaving out of the mulberry bark paper is a preset length; and S20, the mulberry bark paper is folded in two after being twisted, so as to obtain the self-fixing medicated thread. For the self-fixing medicated thread and the manufacturing method provided by the invention, by adding the non-absorbable braided wire at the tail end of the medicated thread part, a part of the non-absorbable braided wire can still be exposed although the medicated thread part fallsinto a cavity after an adhesive tape falls off, so that the medicated thread part is pulled out by pulling the non-absorbable braided wire, and the problem that tweezers cannot take out a medicated thread as the position of the medicated thread falling into the cavity is too deep, so that infection gets serious is solved; and in addition, as the cost of the non-absorbable braided wire is low, themedical cost of a patient can be lowered in the premise of ensuring medical sanitation.

Description

technical field [0001] The invention relates to the technical field of drainage medicinal wire, in particular to a self-fixing medicinal wire for drainage and a manufacturing method thereof. Background technique [0002] Medicinal thread, also known as medicinal twist, was first recorded in "Taiping Shenghui Prescription" in the Song Dynasty. It is one of the characteristic treatments for external treatment of traditional Chinese medicine. Tube function, after the sinus fistula wall is corroded and liquefied, it will flow out with the drug line, which has a drainage effect, especially suitable for branch tubes with multiple tubes and multiple external ports, which can avoid damage to surrounding tissues, protect function and shape, and facilitate postoperative rehabilitation. Shorten wound healing time. [0003] However, the medicine thread routinely used in clinical practice is often inserted into the lumen, and the end of the medicine thread protruding out of the body is ...
