Problems solved by technology
[0004] However, the above-mentioned CN201643114U has the disadvantage of inconvenient operation, for example, when the piston rod equipped with the piston is pulled out from the syringe tube, due to the lack of gripper It is difficult to pull out; another example is that when the surgeon is operating, because the outer wall of the syringe tube lacks the abutting part for the finger to abut against, it seriously affects the operation effect and efficiency

Embodiment Construction
[0011] please see figure 1 , a syringe container 1 is given, the syringe container 1 has a cavity 11, and a first abutting flange edge 12 and a second abutting flange edge 12 are formed on the outer wall of the upper part of the syringe container 1 Flange sides 13, wherein: the first abutting flange side 12 is formed at the mouth of the cavity 11, and the second abutting flange side 13 is located below the first abutting flange side 12, the first and second abutting flange sides The area between the two abutting flanges 12, 13 is formed as a receiving space 14 for receiving fingers of the surgeon. A pair of first finger rests 121 extend on the aforementioned first abutting flange 12 and around the circumferential direction of the first abutting flange 12 , and the pair of first finger rests 121 are 180° apart from each other. And a pair of second finger rests 131 extend on the second against the flange edge 13, the pair of second finger rests 131 are 180° apart in the circ...

The invention relates to a piston type flusher and belongs to the technical field of medical appliances. The piston type flusher comprises a syringe type container and a piston rod, and is characterized in that a first abutting flange and a second abutting flange are formed at the outer wall of the upper portion of the syringe type container, the first abutting flange is arranged at the cavity mouth position of the container, a first finger rest is respectively formed by extensions of corresponding two sides of the first abut flange, the second abutting flange is arranged below the first abutting flange, and a second finger rest is respectively arranged at two corresponding sides of the second abut flange, the second finger rest corresponds with the first finger rest, and a containing space is arranged between the first abut flange and the second abut flange. A finger buckling ring is formed at one end face of the cavity mouth, facing to the container, of the piston rod. The piston type flusher has the advantages of being capable of being abutted by hands of an operator to enhance operational effect and capable of improving operational efficiency, and capable of being inserted by hands of the operator to push and pull the piston rod to suck liquid conveniently.
Description
technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a piston-type flusher for flushing wounds of postoperative patients. Background technique [0002] In the prior art, most of the balloon irrigators are used to flush the wounds of postoperative patients. The structure of the balloon irrigator is composed of Chinese patents CN201782822U (irrigator for orthopedic surgery), CN201308668Y (negative pressure suction irrigator), The technical content disclosed in CN201131966Y (reversible minimally invasive irrigator) and CN201257178Y (controllable irrigator for general surgery) can be found here. Because the use of the balloon flusher is relatively cumbersome and the balloon body is in danger of being separated from the syringe container, it is not highly valued by surgeons. [0003] Piston-type irrigators can make up for the aforementioned shortcomings of balloon-type irrigators, and there are many examples in pu...
