Utility model content
The technical problems to be solved in the utility model is to provide a kind of clinical manipulation medical three-way valve easily, saves calparine cap, reduces costs.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of medical three-way valve, comprise be connected with each other logical three-way body and the control valve being arranged on three-way body center, described three-way body comprises the first entrance, the second entrance and exit, described control valve place is provided with three through holes connected with the first entrance, the second entrance and exit, described first entrance is identical with the structure of described second entrance, comprises with the shell of infusion channel, the rubber stopper be arranged in shell, base and elastomer;
Described infusion channel comprises cavity A and cavity B; Shell is outside equipped with external screw thread, and cavity A inwall is provided with female thread;
Described rubber stopper is arranged in described cavity A; Gathering sill is provided with bottom described rubber stopper; The top of rubber stopper is provided with medicine liquid channel, and this medicine liquid channel surrounding is provided with medicine outlet hole; The outer wall of described rubber stopper is provided with salient point;
Described base is arranged in described cavity B; This base comprises substrate and is arranged at the lead on substrate; Described lead stretches in described gathering sill, and rubber stopper moves up and down along lead;
Described elastomer is arranged at the below of rubber stopper, is enclosed within described lead; Described substrate is arranged at the bottom of cavity B, for fixing described lead.
Further, the first described entrance and described second entrance are provided with steam vent; Described steam vent overcoat has rubber finger sleeve.
Further, described rubber finger sleeve is provided with the fin making an obeisance to grip.
Further, described exit is provided with helmet.
The beneficial effects of the utility model: this utility model structure is simple, being convenient to tube for transfusion and being connected with threeway, without the need to using calparine cap to be connected with draw point during connection, avoiding draw point to accidentally injure, cost-saving; Meanwhile, adopt three-way valve of the present utility model, can also ensure aseptic.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional view of the first entrance.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is elaborated.
As shown in Figure 1-2, for a kind of medical three-way valve of the present utility model, comprise the three-way body 1 being connected with each other logical and the control valve 2 being arranged on three-way body 1 center, three-way body 1 comprises the first entrance 3, second entrance 4 and outlet 5, control valve 2 place is provided with three with the first entrance 3, second entrance 4 with export 5 through holes connected (not shown in FIG.), first entrance 3 is identical with the structure of the second entrance 4, comprises with the shell 6 of infusion channel, rubber stopper 7, base and the elastomer 9 be arranged in shell 6.Infusion channel comprises cavity A10 and cavity B11; Shell 6 is outside equipped with external screw thread, and cavity A10 inwall is provided with female thread;
Rubber stopper 7 is arranged in cavity A10; Gathering sill 71 is provided with bottom rubber stopper 7; The top of rubber stopper 7 is provided with medicine liquid channel 72, and this medicine liquid channel 72 surrounding is provided with medicine outlet hole 73; The outer wall of rubber stopper 7 is provided with salient point 74.
Base is arranged in described cavity B11; The lead 82 that this base comprises substrate 81 and is arranged on substrate 81; Lead 82 stretches in gathering sill 71, and rubber stopper 7 moves up and down along lead 82.
Elastomer 9 is arranged at the below of rubber stopper 7, is enclosed within lead 82; Substrate 81 is arranged at the bottom of cavity B11, for fixed guide post 82.
In the present embodiment, the first entrance 3 and the second entrance 4 are provided with steam vent 12; Steam vent 12 overcoat has rubber finger sleeve 13.
In the present embodiment, rubber finger sleeve 13 is provided with the fin 14 making an obeisance to grip.
In the present embodiment, export 5 places and be provided with helmet 15.
When three-way valve of the present utility model uses, the conehead of tube for transfusion is inserted shell, the salient point 74 of rubber stopper 7 retreats along the female thread in cavity A10, and meanwhile, whole rubber stopper 7 retreats, and elastomer 9 is compressed, and medicinal liquid flows out from medicine outlet hole 73; After having infused, extract the conehead of tube for transfusion, elastomer 9 resilience, rubber stopper moves forward, and is blocked by cavity A10, ensures aseptic.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; this utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed this utility model.The claimed scope of this utility model is defined by appending claims and equivalent thereof.
