Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, relates more specifically to a kind of Y type adapter.
Background technology
Interventional therapy is the emerging therapeutic method between surgery, medical treatment, be exactly under medical imaging (X line, ultrasonic, CT, MRI) guides, blood vessel, skin are done diameter several millimeters minim channel or through the original pipeline of human body, special conduit or apparatus are inserted to diseased region, carry out the method diagnosed radiography, treatment or gather tissue.Percutaneous transluminal coronary angioplasty (PCTA) is that sacculus dilating catheter is inserted into stenosis coronarius by a kind of percutaneous puncture arteries, and under the guiding and monitoring of medical imaging device, expand with the contrast agent Filled Balloon of dilution, make coronary stricture position or the expansion of bypass graft narrow positions, increase myocardial flow, improve heart muscle perfusion, it is a kind of basic coronary heart disease treatment technology, namely on blood vessel, open an osculum, conduit intravascular arrives the positions such as heart and carries out Diagnosis and Treat.
Y type adapter is the necessary utensil of interventional therapy.Y type adapter mainly imports contrast agent, seal wire or other medical apparatus and instruments in conjunction with sacculus dilating catheter is auxiliary in interventional procedure, and controls backflow of blood when using guiding catheter or dilating catheter and provide the fluid path entering interventional systems.In existing design, Y type adapter adopts seal with elastometic washer to be connected for the glass holder of connecting puncture needle and Y-valve main body, the probability of chemical contamination can be caused; And, put in pipe operation process what carry out that sacculus dilating catheter is inserted into coronary stricture place, due to blood overflow during piercing blood vessel, although the operation that medical personnel are carefully skillful, but on the glove of medical personnel, on the pad towel of patient body, even still bloodstained under operating-table, also likely cause secondary pollution or cross infection.
Therefore, how designing a kind of Y type adapter reducing chemical contamination, anti-Hemostatic Oral Liquid overflow, is industry technical problem urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art, a kind of Y type adapter reducing chemical contamination, anti-Hemostatic Oral Liquid overflow is provided, can the deficiencies in the prior art being solved, without the need to installing rubber seal, avoiding secondary pollution or cross infection simultaneously.
The technical scheme in the invention for solving the above technical problem is: a kind of Y type adapter, comprise Y-valve main body, the right lock nut be connected with Y-valve main body one end, the outward extending injection joint that communicates with its inside and the glass holder for connecting puncture needle or conduit in the middle part of Y-valve main body, described Y-valve main body connects glass holder for the other end interference fit seal punctured, being provided with the silica gel plug for sealing Y-valve main body path between described right lock nut and Y-valve main body, silica gel plug having the hole for guiding guide wires therein.
Described Y-valve main body is threaded with right lock nut, the inner side of Y-valve main body is shoulder hole shape, silica gel plug is located in described shoulder hole, and right lock nut inside lower end extends the flange be provided with for compressing closed rubber stopper inside Y-valve main body, and flange fixes rubber stopper by packing ring.
Described right lock nut, Y-valve main body and glass holder adopt medical grade clear polycarbonate material to make.
The outer circumference of described right lock nut is provided with the vertical strip projected parts for rotation grip.
Compared with prior art, the beneficial effects of the utility model: there is easy to operate, the simple feature of structure.The junction of Y-valve main body and glass holder, without the need to installing rubber seal, avoids chemical contamination, and prevents and cause leakage problem because sealing ring is aging; Extrude silica gel plug by rotating right lock nut, thus reach sealing no leakage, the effect of anti-Hemostatic Oral Liquid overflow, it is convenient to bring to medical personnel's operation; Y type adapter entire body all adopts transparent material to design, can more clear identification, is convenient to observe, operation.
Accompanying drawing explanation
Fig. 1 is exploded perspective view of the present utility model;
Fig. 2 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further.
Refer to Fig. 1 to Fig. 2, this utility model relates to a kind of Y type adapter, comprise Y-valve main body 4, right lock nut 1, silica gel plug 3 and glass holder 5, one end of Y-valve main body 4 connects right lock nut 1, the other end connects glass holder 5, silica gel plug 3 is arranged between Y-valve main body 4 and right lock nut 1, silica gel plug 3 is provided with hole, stretch out in the middle part of Y-valve main body and be provided with injection joint 6, injection joint 6 communicates with the inside of Y-valve main body 4, injection joint 6 is mainly used in being connected with other medical apparatus and instruments, injects the medicines such as contrast agent, so that operation technique.
In the present embodiment, the inside, one end of Y-valve main body 4 is shoulder hole shape, in shoulder hole, be provided with silica gel plug 3, the hole of silica gel plug 3 communicates with the inside of Y-valve main body 4, and right lock nut 1 is threaded connection with Y-valve main body 4, right lock nut 1 inside lower end extends and is provided with flange inside Y-valve main body 4 upper end, flange fixes rubber stopper 3 by packing ring 2, and right lock nut 1 makes flange compact silicon plug 3 by pressurization turn-knob, thus closed Y-valve main body path, otherwise, then Y-valve main body path is opened.The outer circumference of right lock nut 1 is provided with vertical strip projected parts, plays the effect of rotation grip.
Y-valve main body 4 connects glass holder 5 for the other end interference fit seal that punctures, and glass holder 5, for connecting puncture needle or conduit etc., without the need to installing rubber seal between Y-valve main body 4 and glass holder 5, reduces chemical contamination, prevents sealing ring aging and the leakage problem that causes.
Right lock nut 1, Y-valve main body 4, glass holder 5 and injection joint 6 all adopt transparent material to make, such as medical grade clear polycarbonate material etc., and the transparent more clear identification of Y type adapter is convenient to observe.
Introduce work process of the present utility model below, only illustrate, this utility model can also be applied in the intervene operation of various disease, and ultimate principle communicates.First puncture needle and glass holder 5 are coupled together, operation consent screws right lock nut 1, and the hole of silica gel plug 3 is in closure state, and the blood in piercing process medium vessels can not be ejected in overflow; In Y-valve main body 4, inject appropriate heparin and normal saline by injection joint 6 and be used as to drain air and anticoagulant, a little air is left at glass holder 5 place time emptying, the object leaving a little air is when after puncture acupuncture medium vessels, can blood enter in bifurcation type adapter, if have blood reflux in bifurcation type adapter at once, namely represent that puncture needle thrusts; Seal wire smoothly by silica gel plug 3, and then through in puncture needle intravasation cavity, extracts puncture needle along seal wire, and recycling seal wire imports sacculus dilating catheter, guarantees the success of putting pipe puncturing operation with this.Avoid secondary pollution unnecessary in operation and cross infection, for health care workers operation bring greatly convenient.
Above specific embodiment is only in order to illustrate structure of the present utility model, and those of ordinary skill in the art can make various deformation and change under design of the present utility model, and these distortion and change include within protection domain of the present utility model.
