Example 1

Referring to fig. 1, 2 and 3, the present embodiment provides a high efficiency tissue clot flusher, which includes: the reservoir 1, the flushing pipe 2, the filter pipe 3 and the non-return assembly 4, in this embodiment the flusher may further comprise a non-slip pad 7.

The mounting hole has been seted up at stock solution bottle 1 top, and slipmat 7 can fixed connection be in the bottom of stock solution bottle 1. In this embodiment, the liquid storage bottle 1 may be filled with a predetermined amount of physiological saline. In addition, the liquid storage bottle 1 can be of a transparent and softened elastic plastic structure. Thus, when the user holds the liquid storage bottle 1, the liquid storage bottle 1 can be deformed by gripping, so that pressure is applied to the liquid storage bottle 1. When the user releases the liquid storage bottle 1, the liquid storage bottle 1 can quickly return to the original shape, so that negative pressure is generated in the liquid storage bottle 1.

One end of the flushing pipe 2 is inserted into the mounting hole and extends into the liquid storage bottle 1, and the other end of the flushing pipe can extend into a focus of a patient, such as urethra, which needs flushing after operation when in use. In this embodiment, the flush tube 2 may be connected to the reservoir tube via a flange 6. When the user 1 applies pressure to the liquid storage bottle 1, physiological saline in the liquid storage bottle 1 can flow into one end of the flushing pipe extending into the liquid storage bottle 1, so that the physiological saline can flow through the flushing pipe 2, further the affected part is flushed, and the tissue blood clot is gradually flushed and shed. Conversely, when the user releases the liquid storage bottle 1, negative pressure is generated in the liquid storage bottle 1, so that the tissue blood clot and physiological saline just washed can be pumped back into the liquid storage bottle 1 through the washing tube 2.

The filter tube 3 is arranged in the liquid storage bottle 1, and a collection cavity for collecting tissue blood clots is formed by the outer side of the filter tube 3 and the inner wall of the liquid storage bottle 1. The side wall of the filter tube 3 is provided with a plurality of through holes 30. The top of the filter tube 3 is connected with the flushing tube 2. In this embodiment, the filter tube 3 serves as a "bridge" for the communication between the flushing tube 2 and the collecting chamber, and physiological saline may be discharged from the collecting chamber to the flushing tube 2 through the plurality of first through holes 30, or may be discharged from the flushing tube 2 to the collecting chamber through the plurality of first through holes 30. In both procedures, the tissue clot cannot pass through the through-hole one 30.

A non-return assembly 4 is provided at the bottom of the filter tube 3 and serves to prevent tissue blood clots in the collection chamber from flowing back into the filter tube 3. Wherein, when the air pressure in the liquid storage bottle 1 is not more than the pressure at the focus, a circulation gap for the tissue blood clot to pass through is formed between the non-return component 4 and the bottom of the filter tube 3. When the air pressure in the liquid storage bottle 1 is larger than the pressure at the focus, the circulation gap is closed.

In this embodiment, when the user releases the liquid storage bottle 1 to generate negative pressure in the liquid storage bottle 1, the non-return assembly 4 is in an "open" state (the circulation gap exists) at this time, and the physiological saline in the flushing tube 2 flows into the filtering tube 3 together with the tissue blood clot, and the physiological saline 1 can flow into the collecting cavity from the through hole one 30 or the circulation gap, and the tissue blood clot can only flow into the collecting cavity from the circulation gap. When the user grips the reservoir 1 to apply pressure to the reservoir 1, the check assembly 4 is in the "closed" state (the flow gap is closed) and the saline in the collection chamber can flow into the flush tube 2 again, but the tissue blood clot cannot return to the filter tube 3 with the saline. Thus, the tissue blood clot at the affected part is washed and timely collected by repeatedly squeezing the liquid storage bottle 2, and the tissue blood clot is ensured not to flow back to the affected part.

Referring to fig. 4, 5 and 6, in the present embodiment, the check assembly 4 may include: a baffle 41.

The baffle 41 may be hinged on one side of the bottom end face of the filter tube 3. The baffle 41 is provided with a plurality of second through holes 410, and similar to the principle of the first through holes 310, physiological saline can pass through the plurality of second through holes 410 and cannot organize blood clots. When a preset included angle a exists between the baffle 41 and the bottom end surface of the filter tube 3, a circulation gap is formed. In this embodiment, the baffle 41 and the filter tube 3 may be hinged and fixed by a torsion spring, and when the liquid storage bottle 1 is in the initial state, the torsion spring may enable the baffle 41 and the filter tube 3 to maintain a preset included angle a=40°. It should be noted that, once the liquid storage bottle 1 is pressed and then is desired to return to the original state (i.e. negative pressure is generated inside), the elastic force of the torsion spring can be quickly and easily overcome, so that the baffle 41 immediately rotates a certain angle to be attached to the filter tube 3, and the circulation gap is closed.

In this embodiment, the cross section of the baffle 41 may be matched with the cross section of the interior of the filter tube 3, i.e., the diameter of the outer edge of the baffle 41 is equal to the inner diameter of the filter tube 3. At least one abutment block 411 is fixedly connected to the outer circumference of the baffle 41. When the baffle 41 is attached to the filter tube 3 (i.e., the flow gap is closed), the abutting block 411 can abut against the bottom of the filter tube 3, so that the baffle 41 is prevented from excessively rotating (extending into and tilting toward the inside of the filter tube 3) and blocking is prevented.

Example 2

Referring to fig. 7 and 8, the present embodiment provides a flusher similar to that of embodiment 1, except for the structure of the check assembly 4. In this embodiment, the check assembly 4 may include: a valve 42.

In this embodiment, the number of valves 42 may preferably be 3. A plurality of valves 42 are circumferentially distributed along the inner wall of the filter tube 3. A plurality of through-holes three 420 are formed in each valve 42. One end of the valve 42 is fixed and the other end is closed. The fixed end of each valve 42 is fixedly connected to the inner wall of the filter tube 3, and the other end points to a position point 5 on the axis of the filter tube 3. The location point 5 is below the fixed end of the valve 42. Wherein, when in the first state, the plurality of valves 42 are separated from each other, and the gaps therebetween together form a flow gap. When in the second state, adjacent valves 42 are in engagement with one another, closing the flow gap.

In this embodiment, each valve 42 may be arcuate in shape, thereby forming a convex portion facing the top of the filter tube 3, and a concave portion facing away from the top of the filter tube 3. Additionally, the valve 42 may be of elastic construction. When normal saline is flushed from top to bottom, the valve 42 is opened and after flushing, the valve 42 automatically rebounds. When the liquid storage bottle 1 is pressed to flush the affected part like a flower without the plurality of valves 42 in the filter tube 3, the plurality of valves 42 are tightly closed, so that normal saline can still pass through the through holes III 420 on the valves 42, and the tissue blood clots in the collecting cavity are blocked by the plurality of valves 42 and the filter tube 3; when the reservoir 1 is released to recover the tissue blood clot and physiological saline from the affected area, the plurality of valves 42 are opened so that both the physiological saline and the tissue blood clot can be smoothly delivered into the collection chamber.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples merely represent a few embodiments of the present utility model, which are described in more detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of the utility model should be assessed as that of the appended claims.
