Technical field
This utility model belongs to technical field of medical instruments, is specifically related to baffle plate adjustable type syringe negative-pressure drainage system.
Background technology
Drainage system is general in clinical practice, the drain such as postoperative in hematocele in surgical postoperative skin pouch, mammary gland.Clinical conventional device is: 1. drive produced continuous negative pressure device by electromechanics, 2. utilized the simple and easy drainage system of syringe and drainage catheter self manufacture by medical worker.In the time that syringe is taken out full hydrops, close drainage catheter with hemostasis clamp, and syringe is separated with drainage catheter, overflow waste liquid in syringe, then reconnect syringe and drainage catheter.
But the shortcoming of existing negative pressure drainage device is: use the dynamo-electric negative pressure producing of tradition, high to equipment requirements, noise is large, and restriction patient's movement; While using the simple and easy drainage system of self-control, in practical operation, need repeatedly syringe is disconnected and is again connected with drainage catheter, increase pollution probability.
Utility model content
The purpose of this utility model is to provide baffle plate adjustable type syringe negative-pressure drainage system, with solve existing dynamo-electric drainage system to equipment requirements high and self-control drainage system pollution probability high problem.
The technical scheme that this utility model adopts is, baffle plate adjustable type syringe negative-pressure drainage system, comprise syringe, the needle nipple of syringe is connected with respectively drainage catheter and drainage bag by three-way valve, syringe comprises injection handle and cover urceolus thereon, and syringe is provided with the fixture for injection handle is located.
Feature of the present utility model is also,
Injection handle comprises core bar and is arranged on the piston of its one end, core bar comprises two floors, two floor interconnections are decussate texture, on floor, be vertically provided with the card for locating, the periphery of urceolus is provided with buckle, and buckle is injected the rectilinear motion of handle in urceolus for contacting with card and stopping.
Prolonging direction along floor is evenly provided with one or more card.
Card is fan-shaped, and a side of card is fixed on a side of a floor, between the opposite side of card and another floor, leaves the gap of passing through for buckle.
Buckle comprises the deck that is fixed on urceolus surface, on deck, is provided with protruding card column towards urceolus inner side.
The free end of drainage catheter is inclined-plane, which is provided with multiple side otch for increasing drainage flow.
The beneficial effects of the utility model are,
1. on clinical conventional syringe basis, improvement forms regulatable vacuum suction syringe, simple in structure, easy to operate, has expanded syringe function simultaneously, can economize on resources;
2. utilize three-way valve to change the connection of each several part, relative closure, avoids repeatedly toppling over drainage-fluid and causes retrograde infection, reduces pollution probability.
3. whole device volume is small and exquisite, is easy to carry and is fixed on it patient, less on patient's daily life impact.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is elaborated.
This utility model provides baffle plate adjustable type syringe negative-pressure drainage system, referring to structure chart 1, comprise syringe 1, the needle nipple of syringe 1 is connected with respectively drainage catheter 3 and drainage bag 4 by three-way valve 2, syringe 1 comprises injection handle 5 and cover urceolus 6 thereon, and syringe is provided with the fixture for injection handle 5 is located.
An interface of three-way valve 2 connects 1, one interface of syringe and connects drainage catheter 3, and another interface connects disposable drainage bag 4.When original state, syringe 1 and drainage catheter 3 are communicated with, and in the time that the interior hydrops of syringe 1 acquires a certain degree, can syringe 1 and drainage bag 4 be communicated with by the valve outside regulating three-way valve 2, thereby easily remove the hydrops in syringe 1, and still keep the negative pressure in syringe 1; Reduced the probability of polluting simultaneously.
Drainage catheter 3 can be formed by the flexible pipe partial reequipping of clinical conventional venoclysis needle, removes syringe needle, free end is cut into inclined-plane, and can divides and cut several side mouths in free-ended wall portion, to increase contact area, increases the drainage flow of liquid.
Injection handle 5 comprises core bar and is arranged on the piston 10 of its one end, core bar comprises two floors 9, two floor 9 interconnections are decussate texture, are vertically provided with the card 8 for locating on floor 9, and described card 8 is evenly provided with one or more along the prolonging direction of floor 9.The periphery of urceolus 6 is provided with buckle 7, and buckle 7 is injected the rectilinear motion of handle 5 in urceolus 6 for contacting with card 8 and stopping.
Card 8 is fan-shaped, and a side of card 8 is fixed on a side of a floor 9, between the opposite side of card 8 and another floor 9, leaves the gap of passing through for buckle 7.Buckle 7 comprises the deck 71 that is fixed on urceolus 6 surfaces, on deck, is provided with protruding card column 72 towards urceolus 6 inner sides.
At the interior rotation injection of urceolus 6 handle 5, card column 72 can be passed through from the gap between card 8 and floor 9, pull up and down injection handle 5 along the axis direction of syringe 1, in the time that piston 10 approaches the scale position needing, stop drag injection handle 5, completed the coarse adjustment to injection handle 5 amount of movements; Rotate again injection handle 5, make card column 72 between two cards 8, and then continue to pull injection handle 5, card column 72 is stuck on card 8, realized the fine setting to injection handle 5 amount of movements.
On injection handle 1, constant spacing is provided with multiple cards 8, by card column 72 and the card 8 of urceolus 6 inner sides, can make the position between syringe urceolus 6 and injection handle 4 relatively fixing, thereby in the interior formation of urceolus 1 and maintain certain degree negative pressure, this vacuum magnitude can realize many grades of adjustings by the card 8 of multiple diverse locations of arranging.
Drainage bag 4 is isolated with syringe 1 and drainage catheter 3 under normal circumstances, when the interior amount of liquid of syringe 1 Shi Caixu that acquires a certain degree is communicated with syringe 1 and drainage bag 4 by three-way valve 2, waste liquid is removed; The direct drain of drain enters syringe 1 Inner, is convenient to observe and quantitative statistics, draws materials simple.Drainage catheter 3, drainage bag 4, three-way valve 2 are clinical conventional consumptive material, and cost is low, are convenient to the popularization in clinical practice.
