Abstract
The utility model relates to a spring knob type Y-shaped hemostasis valve which comprises a Y-shaped pipe (10), a standard Luer joint (20) and a clamping cap (30), wherein the standard Luer joint (20) and the clamping cap (30) are respectively arranged at two ends of the Y-shaped pipe (10). The clamping cap (30) comprises a valve cap (31), a spring seat (311) and a nut (312) which are arranged in the valve cap (31), wherein a spring (313) is arranged between the spring seat (311) and the nut (312). The spring knob type Y-shaped hemostasis valve further comprises a silicone seat (314) and a silicone tube (315), wherein the silicone seat (314) is arranged in a pipe opening of the Y-shaped pipe (10), and the silicone tube (315) is arranged on the silicone seat (314) and is internally provided with a silicone ring (316). The spring knob type Y-shaped hemostasis valve disclosed by the utility model can reach great hemostasis effect in a process of assisting a guide wire and a guide pipe to enter a vessel, is convenient to operate and has a simple structure.
Description
Technical field
This utility model relates to medical apparatus and instruments, the haemostatic valve of particularly stopping blooding for blood vessel.
Background technology
At present, known Y type haemostatic valve structure is to be assembled by Y-piece spare, joint, deduction cap.After seal wire or foley's tube enter Y type haemostatic valve, by turn-knob or pressing haemostatic valve, make the silica gel ring and seal wire or the conduit fluid-tight engagement that are installed in the deduction cap, and reach the effect of hemostasis.And common knob haemostatic valve is screwed to the end to knob by counter clockwise direction, and at this time Y-valve is in the state of standard-sized sheet, after the doctor puts into seal wire, clockwise knob is screwed to half-open position, then seal wire is penetrated blood vessel.At this time, need the doctor that good experience is arranged, the too pine of revolving will be leaked blood, and what revolve is too tight, and the operation of seal wire is just very difficult; In addition, common pressing type haemostatic valve need be pressed deduction cap makes Y-valve be in full-gear, pulls up deduction cap on seal wire to be put into is backward Y-valve is closed, to reach the hemostasis purpose.Obviously like this, can prolong operating time.
Summary of the invention
This utility model provides a kind of spring knob formula Y type haemostatic valve, with turn-knob with press two kinds of structures and combine, uses simultaneously spring that bonnet is automatically reset rapidly.Solve operation technique inconvenience in the prior art, operating time length or the not good problem of haemostatic effect.
This utility model provides a kind of disposable spring knob formula Y type haemostatic valve, comprises Y-piece spare (10), is arranged at standard Luer joint (20) and the deduction cap (30) at Y-piece spare (10) two ends respectively; Described deduction cap (30) comprises bonnet (31), is arranged at spring base (311) and screw thread bud medicated cap (312) in the bonnet (31), is provided with spring (313) between spring base (311) and the screw thread bud medicated cap (312); In addition, also comprise the silica gel seat (314) and the silica gel tube (315) that are arranged in Y-piece spare (10) mouth of pipe, this silica gel tube (315) is seated on the silica gel seat (314), and is provided with silica gel ring (316) in silica gel tube (315).Be provided with spring (313) in the further described bonnet (31).In addition, the screw thread phase interlock of the screw thread on the described screw thread bud medicated cap (312) and Y-piece mouth, silica gel seat (314) lower end and Y-piece mouth (10) are combined closely, the upper end is slightly less than the lower end and is close to silica gel tube (315) inwall, increase its closure, and there is circular hole the centre, is convenient to seal wire and passes; Further described silica gel tube (315) is close to Y-piece spare (10) internal wall of pipe orifice, and described silica gel ring (316) is close to silica gel tube (315) inwall simultaneously, and there is circular hole the centre, and part is large on the circular hole, and the bottom is little.
The beneficial effects of the utility model are, can reach better haemostatic effect in the process of assisting seal wire and conduit intravasation, and adopt spring controlled valve medicated cap automatic reset structure, and are simple in structure, easy to operate, and effectively saved operating time.
Description of drawings
Fig. 1 is that the master of this utility model spring knob formula Y type haemostatic valve looks schematic diagram.
Fig. 2 is that the partial structurtes master of this utility model deduction cap place looks schematic diagram.
Fig. 3 is that the partial structurtes master in this utility model Y-piece mouth looks schematic diagram.
The specific embodiment
Describe specific embodiment of the utility model in detail in conjunction with above-mentioned accompanying drawing.
By among Fig. 1 to Fig. 3 as can be known, in operation, counterclockwise screw thread bud medicated cap (312) is screwed to the end, at this time Y-valve deduction cap (30) is in default half-open state, seal wire is intravasation in this state, does not have any leakage blood phenomenon, has so just alleviated doctor's operation easier, save operating time, solve the not good technical problem of haemostatic effect; Screw thread bud medicated cap (312) under this state in, and press bonnet (31), Y-valve deduction cap (30) just is in full open mode, can pass through foley's tube this moment; The size of sacculus dilating catheter and select the size of Y type haemostatic valve to match fully, so that conduit and the silica gel ring (316) opened fully can combine closely, thus the oozing of blood when stoping the conduit intravasation or leakage blood phenomenon; Unclamp deduction cap (30), spring (313) can make bonnet (31) automatically reset, and rotary screwing thread bud medicated cap (312) is to the tightest again, and bonnet (31) is in the state of closing fully, when injecting contrast agent or other liquid from the Y-valve side shoot, more safe and reliable.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that implementation of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
