An OB glue injection device for fiberoptic tube

technical field

The utility model relates to the technical field of medical equipment, in particular to an OB glue injection device for a fiberoptic bronchoscope drug tube.

Background technique

A fiberoptic bronchoscope (referred to as a fiberoptic bronchoscope) is an instrument for diagnosing bronchial diseases by using a light guide composed of tens of thousands of glass or acrylic resins with high transparency into very thin fibers. Its lumen is small, soft and bendable, with strong light-guiding ability, high brightness, and clear vision. It can easily enter the trachea from the oral cavity or nasal cavity to the mouth of each bronchial segment. Doctors can observe the trachea, left and right bronchioles under direct vision. For the condition of opening and mucous membrane, a small brush can be used to gently press and brush the suspicious mucous membrane several times. The brushed material can be used for smear staining and culture examination; or inject a small amount of normal saline to rinse and extract for smear and culture examination. .

Bronchoscopy is a flexible endoscope with a diameter of only a few millimeters made of tens of thousands of ultra-fine glass fibers using modern high technology. Various diagnostic and therapeutic operations for respiratory diseases are playing an increasingly important role in the field of modern respiratory medicine. Its functions are relatively complete. When examining patients, it can directly provide clear, vivid and vivid high-resolution bronchial images, so that patients and their families can have a clear and intuitive understanding of the treatment effect of the disease.

For treatment, the patient's trachea needs to be injected into the body, which requires the drug injection tube that comes with the bronchoscope. Direct injection can speed up the healing of wounds, and OB glue for injection can be used to bond Organ blood vessels or wounds, but the drug injection tube of this fiberoptic bronchoscope cannot be cleaned, and the drug will also cause certain damage to the injection tube, and the price of the fiberoptic bronchoscope itself is high, which leads to hospitals using this The cost of equipment increases, so a hollow catheter is inserted into the fiberoptic tube to guide the OB glue. However, there is currently no relevant equipment that can push the OB glue into the treatment area. If the glue injection device is used, it will lead to the entire The catheters are filled with OB glue, which causes two problems:

First, a lot of OB glue is wasted, because the injected OB glue is only 5ml, and the length of the entire catheter and the inner diameter of its inner tube will lead to a large amount of OB remaining in the inner tube;

Second, it is impossible to accurately inject the appropriate amount of OB glue. If the amount of OB glue injected is too much, it is easy to cause damage to the patient. If the amount of OB glue is too small, the treatment effect will be poor.

Utility model content

In order to overcome the shortcomings of the existing OB glue injection, the utility model provides an OB glue injection device for a fiberoptic bronchoscope drug tube.

The technical scheme adopted by the utility model to solve the technical problem is as follows: an OB glue injection device for a fiberoptic bronchoscope drug tube.

According to another embodiment of the present invention, it further includes that the upper end of the injection head and the reversing valve are connected by pipelines, the reversing valve is installed on the connecting pipe, and the two ends of the connecting pipe are the needle tube connecting head and the air bag connecting head respectively. , The needle tube connector and the air bag connector are connected to the needle tube and the trachea through the joint, and the trachea is connected to the pressing air bag.

According to another embodiment of the present invention, it further includes that the top ends of the needle tube connector and the airbag connector are provided with a concave installation groove, and the connector is inserted into the installation groove.

According to another embodiment of the present invention, it further includes that the inner side of the installation groove is an inner ring extending into the interior of the joint, and the outer side of the installation groove is an outer ring that wraps the joint.

The beneficial effect of the present utility model is that when the OB glue injection device for fiberoptic bronchoscope drug tube is in use, an auxiliary injection device is provided for the injection of OB glue. The weight of the injected OB glue is relatively accurate, which avoids a series of problems caused by the injection of too much or too little OB glue into the patient's body, and meets the treatment needs.

Detailed ways

1-5 is a schematic diagram of the structure of the present utility model, an OB glue injection device for a fiberoptic bronchoscope drug tube, the lower end of the injection head 1 is an insertion head 13, and the upper end of the injection head 1 is connected with the needle tube 2 or the pressing airbag 3. .

This kind of OB glue injection device for fiberoptic bronchoscope drug tube. When using, first inhale the injected amount of OB glue through the needle tube 2. There is a scale on the needle tube 2, and the volume of the OB glue can be known by reading the scale. 2 Connect with the injection head 1, insert the insertion head 13 on the injection head 1 into the pipe for guiding the OB glue, inject the OB glue into the pipe by squeezing the needle tube 2, and then remove the needle tube 2 from the injection head 1. Then, it is connected with the pressing air bag 3. The pressing air bag 3 is similar to the air bag connected to the pressing blood pressure monitor. After continuous pressing, the OB glue injected into the pipeline can be slowly pushed forward, and the outer part of the insertion head 13 can be pushed forward. The diameter should be larger than the inner diameter of the pipe, so that the insertion head 13 is more tightly connected to the pipe, and the OB glue can be moved when the pressing balloon 3 is pressed, and finally the OB glue is squeezed all over the pipe, and the wound needs to be treated with the patient. Contact to complete the information steps.
