Description

A self-fixing medicine thread and its manufacturing method

technical field

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

Medicinal thread, also known as medicinal thread, was first recorded in the "Taiping Shenghui Prescription" of the Song Dynasty. It is one of the characteristic treatments for external treatment of traditional Chinese medicine.

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 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 deep cavities, the drug thread is easy to fall into the cavity. If it falls too deep to be taken out with tweezers, the drug thread will cause foreign body irritation to the affected area and aggravate the infection.

Contents of the invention

The purpose of the present invention is to provide a self-fixing drug thread and its manufacturing method, which can prevent the drug thread from falling into the cavity after the adhesive plaster falls off, so as to avoid aggravating the infection.

The technical scheme provided by the invention is as follows:

A self-fixing medicinal thread, comprising: a medicinal thread; a non-absorbable braided thread connected to the tail end of the medicinal thread; when the self-fixative medicinal thread is in use, the front end of the medicinal thread extends into a lesion, and the end of the non-absorbable braided thread away from the medicinal thread is located outside the human body.

In the above structure, by connecting the non-absorbable braided thread to the tail of the drug thread, when the drug thread falls into the deep cavity and cannot be taken out with tweezers, the end of the non-absorbable braided thread located outside the body can be pulled directly to pull the drug thread out of the body, so as to avoid the drug thread from causing irritation to the affected area and aggravating the infection.

Preferably, the diameter of the non-absorbable braided wire is ≥0.35mm, and the knotting tensile strength is ≥21.2N.

Preferably, the medicinal thread is made of mulberry paper; before the mulberry paper is rubbed, the distance of the non-absorbable braided thread on the surface of the mulberry paper is a preset distance, and the length of the non-absorbable braided thread outside the mulberry paper is a preset length.

In the above structure, the non-absorbable braided thread is extended into a preset distance before the mulberry paper is rubbed, so that the strength of the self-fixing medicinal thread after rubbing is increased at the joint between the non-absorbable braided thread and the medicinal thread, and the non-absorbable braided thread cannot be pulled out during use because the joint is not strong enough.

Preferably, the preset distance is 1/3 to 1 times the length of the mulberry paper before rubbing.

In the above structure, by extending the non-absorbable braided thread into the mulberry paper by 1/3 to 1 time, it can be ensured that the non-absorbable braided thread and the medicinal thread are not easy to fall off after the mulberry paper is kneaded to make the medicinal thread.

Preferably, the preset length is 3-10 cm.

In the above structure, the length of the non-absorbable braided thread left outside the drug thread is set at 3-10 cm to prevent the non-absorbable braided thread from falling into the cavity along with the drug thread if the non-absorbable braided thread is too short.

Preferably, the self-fixing medicine thread further includes: a medical double-sided adhesive tape bonded to the tail end of the medicine thread.

Adhesive medical double-sided adhesive tape is attached to the tail end of the medicine thread, which can fix the tail end of the medicine thread on the skin of the human body to prevent the medicine thread from falling off.

Preferably, the medical double-sided adhesive tape is an antiallergic double-sided adhesive tape.

In the above structure, the use of anti-allergic high-viscosity double-sided tape can prevent allergic reactions on the skin of the patient in the area where the medical double-sided tape is stuck, and the anti-allergic high-viscosity double-sided tape has strong adhesiveness, and the patient will not fall off due to repeated friction while walking.

Preferably, the bonding area between the medical double-sided adhesive tape and the medicine thread has a length of 0.5 cm to 2.5 cm along the length direction of the medicine thread.

A method for making a self-fixing medicinal thread, comprising the following steps: S10: spread out the mulberry paper, place one end of the non-absorbable braided thread on the surface of the mulberry paper for a preset distance, and the length of the non-absorbable braided thread outside the mulberry paper is the preset length; S20: after rubbing the mulberry paper, fold it in half along the middle of the rubbed mulberry paper to obtain the medicinal thread, and one end of the non-absorbable braided thread is located in the medicinal thread.

Preferably, after the mulberry paper is rubbed and folded in half in the step S20, a medical double-sided adhesive tape is pasted on the tail end of the medicine thread.

The invention provides a self-fixing drug thread and its manufacturing method, which can bring the following beneficial effects:

The invention connects the non-absorbable braided thread to the tail end of the medicine thread, so that after the adhesive tape falls off, even if the medicine thread falls into the cavity, part of the non-absorbable braided thread can still be exposed, so that the medicine thread can be pulled out by pulling the non-absorbable braided thread, which solves the problem that the medicine thread falls too deep into the cavity, which makes it impossible to take out the tweezers and aggravates the infection. The price of the non-absorbable braided thread is low, and the medical expenses of patients can be reduced under the premise of ensuring medical hygiene.

Detailed ways

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Apparently, the drawings in the following description are only some embodiments of the present invention, and those skilled in the art can obtain other drawings and obtain other implementation modes according to these drawings without creative efforts.

In order to make the drawing concise, the parts related to the present invention are only schematically shown in each drawing, and they do not represent the actual structure of the product.

【Example 1】

Example 1 discloses a specific implementation of a self-fixing medicine thread, including: medicine thread 3, a non-absorbable braided thread connected to the tail end of the medicine thread 3, the diameter of the non-absorbable braided thread is ≥ 0.35mm, and the knotting tensile strength is 21.2N. By limiting the wire diameter and knotting tensile strength of the non-absorbable braided thread. 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 will be broken due to the excessive force on the non-absorbable braided thread, so that the medicine thread 3 falling into the cavity cannot be pulled out. 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

The selected value is from 0.35mm to 0.399mm, which can be generally applied to medicine wires of various diameters 3 .

【Table 1】

In this embodiment, No. 7 medical silk braided thread 2 is used as the non-absorbable braided thread, the diameter of which is 0.35 mm, and the knotting tensile strength is 21.2 N. Of course, the non-absorbable braided thread can also be medical polyamide suture, medical polypropylene suture or medical polyester suture, etc., which will not be repeated here.

In this embodiment, the medicine thread 3 is made of mulberry paper 1, which is mainly made of mulberry paper 1 and folded in half, and then the medicine thread 3 is divided into No. 1-5, and the corresponding length is 11cm-2.7cm. The specific lengths of various medicine threads 3 and non-absorbable braided threads are shown in Table 2 below.

Both the medicine thread 3 and the non-absorbable braided thread are sterilized by high-temperature and high-pressure steam, which can create a good aseptic environment at the drainage site and avoid exacerbation of the disease caused by contact with bacteria in the affected area.

By connecting the non-absorbable braided wire at the tail end of the medicine thread 3, when the lesion is located in a deep cavity and the medicine thread 3 falls into the cavity, and the medicine thread 3 cannot be pulled out with tweezers, the medicine thread 3 can be pulled out through the non-absorbable braided thread connected to the tail end of the medicine thread 3, so as to prevent the medicine thread 3 from staying in the cavity, causing irritation to the affected area and aggravating infection.

[Example 2]

As shown in Figure 2, on the basis of embodiment 1 in embodiment 2, the medicinal thread 3 of embodiment 2 is made by rubbing mulberry paper 1. Before rubbing the mulberry paper 1, the non-absorbable braided thread is stretched into the mulberry paper 1 for a preset distance, and a part of the length of the non-absorbable braided thread is left outside the mulberry paper 1, which is the preset length. And the preset distance is set to be 1/3～1 times of the length of the mulberry paper 1 before rubbing, and the 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.

By kneading a length of non-absorbable braided thread into the medicine thread 3, the connection strength between the tail end of the medicine thread 3 and the non-absorbable braided thread can be increased, so as to prevent the tail end of the medicine thread 3 from being disconnected from the non-absorbable braided thread due to a large force when the tail ends are directly connected, so that the medicine thread 3 falling into the cavity cannot be pulled out.

When the preset distance is less than 1/3 times the length of the mulberry paper 1 before rubbing, the non-absorbable braided thread may still be pulled out from the medicine thread 3 when a large external force is used to pull the non-absorbable braided thread.

[Example 3]

As shown in FIG. 2 , 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 .

As shown in Figure 1, 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-absorbable braided thread is positioned at the surface of the mulberry paper 1 as a preset distance, and the mulberry paper 1 is rubbed and then folded in half to form the medicine thread 3. At this time, one end of the non-absorbable braided thread is positioned in the medicine thread 3 after rubbing. After rubbing is completed, it is shown in Figure 2.

As shown in Figure 2, 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 medicinal thread 3 along the length direction of the medicinal thread 3 is 0.5 to 2.5 cm in length.

Specifically, the lengths of the bonding regions between the medical double-sided adhesive tape 4 and the medicinal thread 3 corresponding to the medicinal thread 3 of No. 1 to No. 5 are shown in Table 2.

Specifically, the medical double-sided adhesive tape 4 may be connected with the non-absorbable braided wire, or may not be connected with the non-absorbable braided wire.

Among them, the medical double-sided adhesive tape 4 is an anti-allergic double-sided adhesive tape, which consists of an adhesive layer and a release paper. The adhesive layer is made of medical raw material hot-melt adhesive that meets international FDA food-grade standards. The base material is PET, and the release paper is white glassine release paper. The viscosity of the adhesive layer is 7825cps, and the global softening point is 100.8°C. When the anti-allergic double-sided adhesive tape is used for peeling off, there will be no adhesive residue on the skin, which saves the time required for cleaning, ensures the stability of the adhesive tape, and has a high viscosity, so it can be firmly pasted on the skin, is not easy to fall off, can resist allergies, does not irritate the skin, and reduces patients' allergic reactions caused by the medical double-sided adhesive tape 4.

【Table 2】

Limiting the length of the bonding area between the medical double-sided adhesive tape 4 and the medicine thread 3 along the length direction of the medicine thread 3 can prevent the bonding area from being too long and causing an excessively large sticking area with the skin, resulting in discomfort; The medical silk braided thread 2 and the medical double-sided adhesive tape 4 mentioned above are resistant to high temperature and can be sterilized by high temperature and high pressure steam.

The above three embodiments have a wide range of applications, and the self-fixating drug thread can be used regardless of simple or complex fistulas and sinuses on the body surface or cavity, or even other sites requiring drainage and irrigation or in clinical practice.
