Abstract
The utility model discloses a rotary type haemostatic valve, which comprises a standard ruhr joint and a branch pipe, wherein the standard ruhr joint is arranged at one end of a haemostatic valve passage and connected with a medical apparatus, the branch pipe upwards inclines by forming an angle with the haemostatic valve passage, an elastic closed part is arranged at the other end head of the haemostatic valve passage, an opening is arranged at one end of a rotary handle, the rotary handle is installed at the end part of the haemostatic valve passage, and an extruded part arranged at the other end is pressed on the elastic closed part. By adopting the utility model with the structure, a doctor can control the opening and closing states of the haemostatic valve by controlling the rotary handle in an operation, good sealing and pushing performance is realized, the doctor is helped to successfully carry out the operation, and the rotary type haemostatic valve has simple structure, convenient operation and remarkable practical effect.
Description
Technical field
This utility model relates to a kind of sealing device of medical instruments field, specifically is meant a kind of novel rotary haemostatic valve.
Background technology
The interventional medicine technology grew up from the later stage seventies; development along with image technology; often need by percutaneous puncture or by the original passage of human body; special conduit or apparatus inserted deliver to the disease position and diagnose radiography, treatment, tissue sampling, bacteriology, cytology research, biochemical analysis treatment etc.; in the middle of this operation process; in order to reduce damage, minimizing loss of blood to tissue; reduce the operation complicated process, adopt catheter sheath and other conveyer devices, switch etc. through regular meeting.These apparatuses generally adopt certain sealing device to realize in order effectively to reduce loss of blood because it has a haemostatic valve, so blood can outwards not flow out from the sheath pipe, as catheter sheath.This apparatus inserts blood vessel with the sheath pipe earlier when operation, diagnosis of using in performing the operation then or therapeutic device be intravasation by the sheath pipe.Therefore, use sheath pipe can effectively reduce the damage to blood vessel, prevents loss of blood.Conduit and related equipment also can be very easy to enter the disease position, thereby shorten the time of whole surgery, alleviate patient's misery, improve the operation effect.Requirement to this haemostatic valve mainly contains following 2 points, and the first, apparatus or catheter insertion sheath pipe or extraction all can effectively seal.The second, haemostatic valve should be as much as possible little to apparatus or the friction that pipe produces of conduit turnover sheath, otherwise will have a strong impact on its handling, reduces doctor's operating handle, occurs accident sometimes easily.But the haemostatic valve of existing sheath pipe or other apparatuses or sealing device, because its reasons in structure, its haemostatic effect is not fine, especially handling is relatively poor, the carrying out of influence operation on certain program.
The utility model content
At the deficiency of existing haemostatic valve or sealing device structure and performance, this utility model patent provides a kind of rotary haemostatic valve, and it can realize good sealing and propelling movement performance, and is easy and simple to handle, is beneficial to carrying out smoothly of doctor's operation.
Technical solutions of the utility model are, a kind of rotary haemostatic valve, comprise and be arranged at the standard Luer joint that haemostatic valve passage one end is connected with medical apparatus and instruments, and with the angled acclivitous arm of haemostatic valve passage, it is characterized in that haemostatic valve passage other end termination is provided with enclosed elastic spare, rotary handle one end is uncovered, be contained in the haemostatic valve channel end, the extrusion of other end setting is pressed together on the enclosed elastic spare.
Described haemostatic valve channel end is provided with external screw thread, and the female thread of rotary handle inwall setting is twisted rotary handle and is combined in the haemostatic valve channel end.
Described enclosed elastic spare is the silica gel sheet.
Be provided with the Elastic plastic-rubber packing ring between described extrusion and the enclosed elastic spare.
Described haemostatic valve channel end is provided with fin, and rotary handle inwall front end is provided with the cooperation back-off.
Adopt this utility model of said structure, the doctor can control the open and-shut mode of haemostatic valve by the control rotary handle in operation, realize good sealing and push performance, and help the doctor to undergo surgery smoothly, simple in structure, easy and simple to handle, practical function is remarkable.

The specific embodiment
As shown in Figure 1, this utility model main body is a Y shape passage, and passage 2 one ends are provided with the standard Luer joint 1 that is connected with medical apparatus and instruments, and arm 4 forms Y shape with passage 2 angled being inclined upwardly, and is used to connect pressure monitoring devices or other use in perfusion applications.Passage 2 other ends connect rotary handle 3.
Shown in accompanying drawing 2 and accompanying drawing 3, haemostatic valve passage 2 other end terminations are provided with enclosed elastic spare 9, and in the present embodiment, this enclosed elastic spare adopts high-elastic silica gel sheet or other high-elastic gonosome.This silica gel sheet is a cirque structure, its structure such as Fig. 4 and Fig. 5, and it is fixed in haemostatic valve passage 2 tube wall inboards.
In order to increase contacting between extrusion 7 and the enclosed elastic spare 9, this utility model also is provided with the Elastic plastic-rubber packing ring 8 of annular, gasket construction figure such as Fig. 6 and Fig. 7 between extrusion 7 and enclosed elastic spare 9.Extrusion 7 is pressed together on the plastic washers 8, plastic washers 8 repress close enclosed elastic spare 9, and not only contact area becomes big, the open and-shut mode that rotary handle 3 can more effective control enclosed elastic spare 9, and can reduce the damage of 7 pairs of enclosed elastic spares 9 of rigid extrusion, prolong its service life.
During use, with whole haemostatic valve sealing, then will rotate 3 to internal rotation if desired, extrusion 7 is motion extruding plastic washers 8 inwardly, and plastic washers 8 repress close enclosed elastic spare 9, makes it produce deformation with 2 sealings of haemostatic valve passage.In the time of whole haemostatic valve need being opened, outside rotary handle 3, extrusion 7 loses the pressure effect to plastic washers 8 and enclosed elastic spare 9, and plastic washers 8 and enclosed elastic spare 9 restore to the original state haemostatic valve are opened.
If because long-time extruding plastic washers 8 and enclosed elastic spare 9 die down its elasticity, during the sealing property variation, outside rotary handle, firmly extract handle then after, new plastic washers 8 and enclosed elastic spare 9 can change the outfit.Whole device adopts plastics to make, and simple in structure, with low cost, effect is remarkable, can be widely used in the clinical treatment field.
