This utility model provides a kind of six grades of formula aspiration vacuum syringes, comprise syringe, push rod, sealing shroud, described push rod end is provided with described sealing shroud, described push rod is positioned at described syringe and can axially moves and tangential rotation at described syringe, described sealing shroud outer surface is that hermetic seal cooperates with described syringe inner surface, and this aspiration vacuum syringe also comprises makes described push rod be positioned at the gear of described syringe position.
As further improvement of the utility model, described gear device comprises the plate washer that is located on the described push rod, and is located at the engaging tooth on the described syringe.Described engaging tooth can cooperate the pre-position maintenance certain negative pressure that described push rod is fixed on described syringe with described plate washer.
As further improvement of the utility model, to be that six same structures and described syringe scale are corresponding be arranged on the described push rod described plate washer, can described push rod need be fixed on six different positions by operation.
As further improvement of the utility model, described push rod is provided with slide rail, can be smooth along the described push rod of the axial pull of described slide rail the time with described push rod pull to desired location.
As further improvement of the utility model, described push rod is provided with the conversion groove, and two scope of operations that are located on the described push rod can freely be changed.
As further improvement of the utility model, the selection of gear is to control cooperating of described engaging tooth and described plate washer by the described push rod of tangential rotation, so described push rod axially apply the variation that push-pull effort can not cause described gear, so described aspiration vacuum syringe can keep relatively large negative pressure.
As further improvement of the utility model, described syringe front end is provided with female Luer.
The beneficial effects of the utility model are: because described sealing shroud outer surface is that hermetic seal cooperates with described syringe inner surface, this aspiration vacuum syringe also comprises makes described push rod be positioned at the gear of described syringe pre-position, thereby guarantees to keep in the syringe state of negative pressure-pumping; Because be push rod to be positioned by the gear device, make the operator need not to be maintained fixed for a long time posture, alleviated operator's working strength.

[specific embodiment]
Extremely shown in Figure 5 as Fig. 1, the utility model discloses a kind of six grades of formula aspiration vacuum syringes, comprise syringe 0020, push rod 0030, sealing shroud 0010, described push rod 0030 end is provided with described sealing shroud 0010, described push rod 0030 is positioned at described syringe 0020 and can axially moves at described syringe 0020, described sealing shroud 0010 outer surface is that hermetic seal cooperates with described syringe 0020 inner surface, and this aspiration vacuum syringe also comprises makes described push rod 0030 be positioned at the gear of described syringe 0020 pre-position.Sealing overlaps 0010 outer surface and this syringe 0020 inner surface fits tightly together, thereby reaches the purpose of hermetic seal.
As shown in Figure 2, described gear device comprises the plate washer 0031 that is arranged on the described push rod 0030 and is provided with the engaging tooth on the described syringe 0,020 0021 and forms, described plate washer 0031 can cooperate with described engaging tooth 0021 push rod 0030 is fixed on the plate washer position, to keep in the syringe 0020 fixed negative pressure being arranged.
As shown in Figure 3, described push rod 0030 is provided with slide rail 0033, can be smooth along the described push rod 0030 of described slide rail 0033 axial pull with described push rod pull to desired location.
As shown in Figure 4, described syringe 0020 is provided with female Luer 0022 and engaging tooth 0021.
As shown in Figure 5, described 0030 bar that pushes away is provided with plate washer 0031, and conversion groove 0032.To be that six same structures and described syringe 0020 scale are corresponding be arranged on the described push rod 0030 described plate washer 0031, described plate washer 0031 can cooperate by operation and described push rod 0030 need be fixed on six different positions with described engaging tooth 0021, keeps certain negative pressure.The breach of described conversion groove 0032 for being complementary with engaging tooth 0021 can arbitrarily be changed by described conversion groove 0032 operator and to use two scope of operations that are located on the described push rod 0030, reasonable use described pusher structure with its utilization rate maximization.
When human body has hydrops to get rid of, six grades of formula aspiration vacuum of this utility model syringe is connected on the medical three-way device, the other two ends of medical three-way device are connected with liquid collecting container and human body respectively, at first rotating medical three-way device closes six grades of formula aspiration vacuum syringe ports, according to the amount of required extracting bodily fluid along the described push rod of described slide rail 0033 axial pull 0030 to the appropriate location, described push rod 0030 tangentially turns clockwise, engaging tooth 0021 is fixed on corresponding plate washer 0031 place, this moment is with push rod 0030 fixed-site, pull medical three-way device switch then with human body and syringe 0020 port UNICOM, collection container port shutdown.The operator can leave hands six grades of formula aspiration vacuum syringes and carried out other operations this moment, treat that pumping liquid reaches set when quantitative, pull medical three-way device switch with the human body port shutdown, syringe 0020 port is communicated with liquid collecting container, user tangentially is rotated counterclockwise described push rod 0030, and described engaging tooth 0021 near slide rail 0033, is promoted push rod 0030 liquid is pushed in the collection container, continue pumping liquid if desired, repeat aforesaid operations.Behind the EO, syringe ports closed directly six grades of formula aspiration vacuum syringes to be withdrawn get final product.
