Abstract
The utility model belongs to the field of medical apparatuses and instruments, and particularly provides a convenient, sanitary and easy-to-use disposable gastric lavage bag which is improved on the basis of existing gastric lavage medical instruments. According to the disposable gastric lavage bag, a clysis bag (1) is connected with a inflow channel (7) of a tee joint ball valve (3) through an upper connecting conduit (4), an outflow channel (8) of the tee joint ball valve (3) is connected with a negative pressure vacuum extractor (2) through a lower connecting conduit (5), a liquid inlet and outlet channel (9) of the tee joint ball valve (3) is connected with a gastric lavage pipe (6), two L-shaped liquid channels are arranged inside a ball valve core of the tee joint ball valve (3), wherein the two L-shaped liquid channels are perpendicular to each other, the vertex of the two L-shaped liquid channels is the center of the ball, and the depth of each side of each L-shaped liquid channel is as large as the radius of the ball. The valve rotates when a valve handle is wrenched, and the whole disposable gastric lavage bag is switched between a working condition of infusing gastric lavage liquid into the stomach and a working condition of extracting the gastric lavage liquid from the stomach repeatedly as the valve core rotates. The structure of the disposable gastric lavage bag guarantees that a gastric lavage pipeline system is integrally formed, and the disposable gastric lavage bag is easy to implement, low in cost and convenient to use.
Description
Technical field
The invention belongs to medical instruments field, especially the medical instruments to existing gastric lavage are improved, and obtain a kind of convenient, healthy and wieldy disposable gastric lavage bag.
Background technology
In the emergency treatment of hospital; run into the poisoner of a variety of causes through regular meeting; common as organophosphorus pesticide poisoning, spiritual class overdose poisoning, alcoholism etc., will remain in by emergency gastric lavage that the mode of medicine by gastric lavage in the digestive tract excrete is the highly effective measure of rescuing such patient.Yet, when emergency medical personnel is carried out gastric lavage now, after inserting good gastrolavage tube often, gastrolavage tube is stayed an external end to be enclosed within the pipe joint that links to each other with the container of filling liquid of gastric lavage such as enema bag etc., after treating that liquid of gastric lavage all enters patient's gastric, after again gastrolavage tube being pulled up from the pipe joint that links to each other with the container of filling liquid of gastric lavage, be enclosed within again with pipe joint that vacuum extractor links to each other on, with the liquid of gastric lavage sucking-off, so finish once complete circulation.When rescuing a patient, need repeatedly finish the action that gastrolavage tube is pulled up, put from pipe joint back and forth.
Summary of the invention
Technical problem to be solved by this invention:
Need when overcoming gastric lavage in the prior art frequently with gastrolavage tube from enema bag and pipe joint that vacuum extractor links to each other on the problem of plug back and forth.
The technical solution used in the present invention:
Disposable gastric lavage bag of the present invention, formed by the enema bag that stores liquid of gastric lavage, vacuum extractor, tee ball valve, last connecting duct, following connecting duct and gastrolavage tube, enema bag 1 links to each other with the inflow road 7 of tee ball valve 3 by last connecting duct 4, connecting duct 5 linked to each other with vacuum extractor 2 under the efferent tract 8 of tee ball valve 3 passed through, and the liquid Vomitory 9 of tee ball valve 3 links to each other with gastrolavage tube 6.
It is the centre of sphere that there are two orthogonal and summits the spherical valve core inside of tee ball valve 3, and every limit degree of depth is " L " type fluid passage of the radius of a ball, and this spool links to each other with valve handle 10.
In tubing, add tee ball valve, can guarantee that gastrolavage tube is in opening state all the time, meanwhile the other end of tubing can only connect one of them that pours into liquid of gastric lavage branch road and extraction liquid of gastric lavage branch road, the switching of pipeline only needs to finish by pulling the tee ball valve handle that links to each other with spherical valve core, because spherical valve core has adopted " L " type structure, corresponding handle only need be pulled 90 degree.
Beneficial effect of the present invention:
Owing to adopted tee ball valve, make the gastric lavage process be in the closed pipeline system, do not need from the joint of pipeline plug gastrolavage tube repeatedly, thereby raising therapeutic efficiency, and after the present invention will store the enema bag, vacuum extractor, tee ball valve of liquid of gastric lavage, two connecting ducts and gastrolavage tube are sterilized simultaneously up and down, put into the gastric lavage bag after airtight aseptic transparent plastic bag is formed disposable sterilization together, each gastric lavage only need be unpacked and be got final product, and is very easy to use.
Description of drawings
First kind of duty of the disposable gastric lavage bag of Fig. 1 is followed successively by the enema bag 1 that stores liquid of gastric lavage, last connecting duct 4, tee ball valve 3, following connecting duct 5, vacuum extractor 2 and gastrolavage tube 6 among the figure.This moment, the handle 10 of tee ball valve 3 was in the position parallel with the tee ball valve major axis, " L " type fluid passage of tee ball valve spool is connected connecting duct 4 and gastrolavage tube 6 by flowing into road 7 respectively with liquid Vomitory 9, and namely this moment, enema bag 1 and gastrolavage tube 6 were connected.Connecting duct 5 links to each other with vacuum extractor 2 efferent tract 8 of tee ball valve 3 by connecting down, because the existence of " L " shape channel design in the spherical valve core, this moment, vacuum extractor 2 and gastrolavage tube 6 were in the state that is not connected.
Second kind of duty of the disposable gastric lavage bag of Fig. 2 is followed successively by the enema bag 1 that stores liquid of gastric lavage, last connecting duct 4, tee ball valve 3, following connecting duct 5, vacuum extractor 2, gastrolavage tube 6 among the figure.This moment, the handle 10 of tee ball valve 3 was in the position vertical with the tee ball valve major axis, and " L " type fluid passage of tee ball valve spool is connected gastrolavage tube 6 and following connecting duct 5 respectively by liquid Vomitory 9 and efferent tract 8.This moment, vacuum extractor 2 and gastrolavage tube 6 were connected, because the existence of " L " shape channel design in the spherical valve core, enema bag 1 and gastrolavage tube 6 are in the state that is not connected.
The front view of Fig. 3 tee ball valve, this tee ball valve 3 comprises and flows into road 7, efferent tract 8, liquid Vomitory 9, and it is the centre of sphere that there are two orthogonal and summits spherical valve core inside, every limit degree of depth is " L " type fluid passage of the radius of a ball, and this spool links to each other with valve handle 10.Handle 10 is parallel with the major axis at 8 places with 7 among this figure, so 7 and 9 are connected; If valve handle 10 is pulled 90 degree, position as shown in Figure 2, be connected this moment 8 and 9.
The left view of Fig. 4 tee ball valve, 7 for flowing into the road, and 8 is efferent tract, and the valve handle 10 of ball valve links to each other with spherical valve core, drives valve core rotation by stirring this handle 10, thereby realizes the switching from first kind of duty to the second kind of duty.
The specific embodiment
Embodiment 1
