RU2556497C1 - Method for poison suction from wound canals after snake bite - Google Patents

Abstract

FIELD: medicine.

SUBSTANCE: invention refers to medicine and concerns the delivery of care for people suffered from a snake bite. A method involves poison suction from wound canals after the snake bite by means of a syringe used to generate a suction pressure. Besides, two cannulas are connected to a T-joint, to a third end of which an anaesthetic and/or antidote tube is attached. The cannulas are inserted into the wound canals, and the tube content is introduced. The tube is then detached; the syringe is attached into its place, and the suction pressure is generated.

EFFECT: method provides the more effective poison removal from the wound canals and relieves pain that might accompany this procedure.

Description

The method relates to medicine and can be used for individual use by a wide population. Usually snake bites occur in areas remote from medical facilities. One of the effective ways to reduce the impact of poison on the victim’s body can be to reduce the amount of poison in the wound by aspirating the poison from the wound. Usually, the victim is sucked out of the wound by the mouth either by the victim himself or by an attendant. In this way, subject to precautionary measures, up to 20-30% of the poison can be removed (Internet resource http://www.spruce.ru/urgent/toxic/bites/snakebite_3.html).

This method is ineffective, and in some cases may not be implemented at all.

A known method of suctioning blood during a surgical operation (patent application RU No. 2006134571), in which a tip connected by a tube to a container, is placed in the region of the suction blood, and a vacuum is created by a vacuum pump through the container.

The method allows the extraction of blood from a wound of any kind, however, its implementation in the field is difficult because of the bulkiness and complexity of the equipment used.

A known method for removing liquid mass from the surgical field during microsurgical operations (patent application RU No. 94035254), in which a cannula is attached to the tip of the syringe, which is inserted into the surgical field and creates a vacuum by the piston of the syringe. A cannula is a modified “blunt” needle, devoid of its sharp cutting edge. A rounded end with a laterally displaced downward hole avoids traumatic tissue cutting. Resting on an obstacle - whether it be a vessel, nerve or ligament, a correctly selected cannula either bends around it or spreads the tissue, practically without damaging it.

The specified method allows you to remove poison from the surgical field (from wound canals from a snakebite) for individual use.

The disadvantage of this method is that in this case it will be necessary to insert and remove a cannula into each wound canal from a snake bite, which will add additional pain to the victim.

A known method for removing poison from wound canals after a snakebite (patent US 8696640 B2, Russell Churchill, priority 01/10/2011, publ. 04/15/2014) is taken as a prototype in which a special-shaped needle is attached to the tip of the syringe, which is inserted into the wound channel after a snake bite and create a vacuum with a syringe.

The specified method allows you to remove poison from wound canals from a snakebite for individual use.

The disadvantage of this method is that in this case it will be necessary to insert and remove a needle of a special shape in each wound channel from a snake bite, which will add additional pain to the victim.

Signs of the prototype, coinciding with the essential features of the proposed method, is the insertion of a needle of a special shape into the wound channel, attaching it to the tip of the syringe and creating a vacuum using a syringe.

Distinctive features are as follows

1. Previously, two cannulas are connected to a tee, to the third end of which a tube with anesthetic and / or antidote drug is attached.

2. At the time of use, cannulas are inserted into both wound channels of a snakebite, the drug is injected from the tube into the wound channels, the tube is disconnected and a syringe is attached in its place, with the help of which a vacuum is created to remove the contents of the wound channels, including poison.

3. The cannulas with a tee are connected by flexible tubes.

The invention is aimed at solving the problem of increasing the efficiency of removing poison from wound canals after a snake bite and reducing pain during this procedure.

The technical result of the invention is to ensure the removal of snake venom from wound canals and the creation of anesthetic and therapeutic effect at the site of a snake bite.

The technical result is ensured by the fact that in the method of aspirating poison from a wound after a snakebite, two cannulas are pre-connected to a tee, to the third end of which a tube with anesthetic and / or antidote is attached, cannulas are inserted into wound canals, the contents of the tube are inserted into wound canals, disconnected a tube, attach a syringe in its place and create a vacuum.

For ease of use, the cannula is connected to the tee with flexible tubes.

Differences from the prototype prove the novelty of the technical solution described in the claims.

The new approach allows for the simultaneous removal of poison from both wound canals of a snake bite by inserting cannulas into both wound canals at once and creating a vacuum at once for both cannulas, which confirms the compliance of the claimed technical solutions with the patentability condition “industrial applicability”.

The prior art does not know the essential features of the proposed method, characterized in the claims, which confirms their compliance with the condition of patentability "inventive step".

The invention is illustrated by drawings, where in FIG. 1 shows a connection diagram of a cannula with a tee; in FIG. 2 shows a connection diagram of a cannula with a tee through flexible tubes; in FIG. 3 shows a connection diagram of a cannula with a tube; in FIG. 4 shows the connection diagram of the cannula with a syringe.

In FIG. 1 cannula 1 attached directly to the tee 2.

In FIG. 2 cannulas 1 are connected to the tee 2 through flexible tubes 3 having an end 4 corresponding to the opening of the cannula 1 and an end 5, the opening in which corresponds to the size of the end of the tee 2.

In FIG. 3 cannulas 1 are attached to a tee 2, to the third opening of which is attached a tube 6 with anesthetic and antidote drug.

In FIG. 4 cannulas 1 are connected to a tee 2, to the third opening of which a syringe 7 is attached.

The method is implemented as follows. Immediately after a snakebite, cannula 1 connected directly to tee 2 (Fig. 1), or through flexible tubes 3, 4, 5 (Fig. 2), is unpacked, connected through tee 3 to a tube 6 containing an anesthetic and / or antidote ( Fig. 3) (for example, the antidote of biological snake venoms, patent application RU No. 99105467), observing the rules for injection, insert the cannula 1 into the wound canals, squeeze the contents of the tube 6 into the wound canals. After some time, the tube 6 is disconnected from the tee 2 and a syringe 7 is attached in its place (Fig. 4), with which the contents of the wound channels are sucked. As the syringe is filled, it is disconnected from the tee, the contents are released, connected to the tee and the procedure continues. If the anesthetic drug and the antidote cannot be stored in one tube, then the procedure can be distributed - first the antidote is administered, then the anesthetic drug, then suction is performed. If there are no tubes with drugs or if the victim easily tolerates pain, then you can immediately begin to suck out the contents of the wound channels.

It is advisable to equip medical kits with a kit consisting of cannulas with a tee, tubes of drugs and a syringe. In the absence of a syringe, the contents of the wound canals can be sucked out by mouth through a tube attached to the tee. To exclude contact with the contents of the wound channels, it is possible to insert a sealed container into the section of the tube attached to the tee.

A method of aspirating poison from wound canals after a snakebite, including the use of a syringe, with which a vacuum is created, characterized in that the two cannulas are pre-connected to the tee, a tube with anesthetic and / or antidote is attached to the third end, the cannulas are inserted into wound channels, introduce the contents of the tube into the wound channels, disconnect the tube, attach a syringe in its place and create a vacuum. 2.
