Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to disposable biopsy cap with check valve function that scope stretches into sealed and liquid, the gas collection of end when being applicable to digestion scope inspection.
Background
When inspection and treatment are carried out under the digestion endoscope, disposable biopsy forceps and treatment accessory consumptive materials under the endoscope need to be used, such as: snare, electric knife, hemostatic forceps, net basket, metal clip, etc. The liquid in the digestive tract cavity overflows from the central working channel of the biopsy cap and splashes around because the abdominal pressure of a patient is increased along with the examination and treatment, thereby influencing the normal operation of a doctor and the surrounding environment; meanwhile, when the working channel is not tight, a part of gas leaks, and the digestive tract cavity is not sufficiently inflated, so that the observation, searching and treatment of the pathological changes of a doctor are influenced.
A camera probe used in abdominal cavity examination in China is mainly characterized in that a camera is placed in a patient body through a pipeline, a large amount of blood often overflows from a conventional plug due to the abdominal pressure in the patient body and the guiding effect of a data line of the camera, so that the medical environment is polluted, the psychology of medical care personnel is adversely affected, meanwhile, germs possibly exist in the blood of the patient and are a potential threat to the patient and the medical care personnel, a commonly used examination system in the current stage of China is imported abroad, so that corresponding supporting facilities are not completely fit for the practical application of China, and a great difference between China and the western countries lies in that the patient facing high-precision equipment in China is far higher than the foreign country, so that the patient is difficult to be cleaned once like European and American countries, the waiting time of the patient is delayed, the practical use time is shortened, and the efficiency is improved and the current situation is solved, in order to avoid liquid leakage, medical personnel in China often use disposable gloves to cover the outer side of the biopsy cap to collect blood, but the leakage of gas cannot be avoided, and the blood collection effect is also poor.
Disclosure of Invention
The utility model provides a device of disposable one-way leak protection biopsy cap to the liquid of solving the alimentary canal intracavity can spill over in the central working channel of biopsy cap, spatters around, influences the problem of doctor's normal operating and surrounding environment.
The utility model adopts the technical proposal that: including biopsy cap body, sealed snap ring, collect the bag, the arc is sealed, the toper type keeps off the ring, block the ball, spring and fender ring, wherein the inside front end fixed connection toper of biopsy cap body is sealed, the sealed one end of arc and the outside front end fixed connection of biopsy cap body, the other end and biopsy cap main part rear end joint, be equipped with a branch road in the middle of biopsy cap body, cup joint a collection bag on this branch road, it links to each other with the branch road through a snap ring to collect the bag, top and middle part difference fixed connection toper in the branch road keep off the ring and keep off the ring, keep off ring upper portion and spring fixed connection, it is located between spring and the toper fender ring to block the ball.
The biopsy cap body of the utility model is made of medical rubber.
The end of the branch has an annular groove and an annular bulge.
The breach is evenly laid to flat retaining ring edge.
The utility model has the advantages of novel structure, disposable is equipped with the check valve, can also avoid gaseous liquid spill after finishing collecting when guaranteeing that gaseous smooth flow in collection bag, and the scope stretches into the sealed of end when being applied to the digestion scope inspection, and liquid, gaseous collection, can avoid from the internal waste gas waste liquid polluted environment who overflows of patient and influence medical personnel's operation, very big reduction medical personnel's work load, also reduced the possibility that the germ passes through blood propagation.

Detailed Description
Comprises a biopsy cap body 1, a sealing snap ring 2, a collecting bag 3, an arc seal 4, a conical seal 5, a conical baffle ring 6, a blocking ball 7, a spring 8 and a flat baffle ring 9, wherein the conical seal 5 is fixedly connected with the front end inside the biopsy cap body 1, one end of the arc seal 4 is fixedly connected with the front end outside the biopsy cap body 1, the other end is clamped with the rear end of the biopsy cap body 1, a branch 101 is arranged in the middle of the biopsy cap body 1, the collecting bag 3 is sleeved on the branch, the collecting bag 3 is connected with the branch 101 through the snap ring 2, the collecting bag can collect waste gas and waste liquid seeped out from the conical seal ring (5), the conical baffle ring 6 and the flat baffle ring 9 are respectively and fixedly connected with the upper part and the middle part in the branch 101, the upper part of the flat baffle ring 9 is fixedly connected with the spring 8, the blocking ball 7 is positioned between the spring 8 and the conical baffle ring 6, the upper conical seal ring, meanwhile, the blocking ball 7 is also ensured to form sealing with the blocking ball under the condition of no pressure difference between the inside and the outside, so that the gas circulation is blocked;
the biopsy cap body 1 of the utility model is made of medical rubber and has good elasticity;
the end of the branch 101 has an annular groove 102 and an annular protrusion 103, which are configured to clamp the snap ring 2, so that the collecting bag 3 can be more firmly fixed, and the leakage of waste gas and liquid is reduced, thereby ensuring the overall sealing performance.
The flat baffle ring 9 is uniformly provided with gaps 901.
Principle of operation
When in use, the arc-shaped sealing ring 4 is pressed into the rear end opening of the biopsy cap body 1, so that the whole biopsy cap body is sealed, and a biopsy probe penetrates through the arc-shaped sealing ring 4 and then penetrates through the conical seal 5 to enter inspection equipment; a branch 101 is arranged between the two sealing rings, a collecting bag 3 is sleeved on the branch for collecting waste gas and waste liquid, because the pressure in the abdominal cavity of the human body is higher than the atmospheric pressure, see figure 4, when gas enters between the two sealing structures, the spring 8 is compressed, so that the one-way valve is opened, the gas and blood are collected in the collecting bag, the collecting bag can collect the waste gas and waste liquid seeped out by the conical sealing ring 5, the collecting bag 3 naturally drops below, the blocking ball 7 is arranged on the spring 8, the flat baffle ring 9 is uniformly provided with gaps for the gas and blood to flow to the collecting bag 3, meanwhile, the blocking ball is pressed on the flat baffle ring below by the high pressure in the abdominal cavity of the patient, when the probe is taken out from the patient, the pressure in the elastic collecting bag is higher than the external pressure, see figure 3, at this moment, the blocking ball 7 is pressed on the conical baffle ring 6 by the spring force, sealing is formed, leakage of liquid and gas is avoided, and then the collecting bag is taken down.
