Description

Hemostasis valve device

The embodiment relates to a hemostatic valve device.

The hemostatic valve device is a device for introducing a conduit, a guide wire, or a catheter (hereinafter, catheters) into a blood vessel. The hemostatic valve device guides the catheter to be accurately inserted into the percutaneous artery or vein when performing cardiovascular angiography or percutaneous coronary angioplasty. In addition, the hemostatic valve device prevents backflow of blood through the percutaneous artery or vein. If necessary, a drug can be injected through a hemostatic valve device.

As a hemostatic valve device, Korean Patent Application Laid-Open No. 10-2001-0022303 (published on 15 March 2001, hereinafter referred to as this document) describes a configuration that is reduced and expanded in conjunction with the rotation of the cap. However, the hemostatic valve device of this document has a problem in that air is introduced into the blood vessel when catheter is inserted into a percutaneous artery or vein, or when a drug is injected. For example, air bubbles may occur in the contrast medium itself. Alternatively, it may occur in the process of injecting a contrast agent. When air is introduced into the blood vessel, air bubbles can cause air embolism, which blocks the blood vessel. Likewise. If air enters the patient's blood vessel, it can be fatal to the patient's life. When air bubbles block blood vessels leading to the heart or block blood vessels in the brain, the patient may die due to cardiac arrest or cerebral hemorrhage.

Therefore, the operator should take great care to prevent air from entering the blood vessel when inserting catheters into a percutaneous artery or vein, or injecting a drug. Therefore, there is a problem that the operator's fatigue is large, and a lot of trained personnel are required for the procedure. Above all, there is a problem that the probability of success of the procedure is greatly reduced.

1 is a view showing a hemostatic valve device according to an embodiment.

Referring to FIG. 1, a hemostatic valve device according to an embodiment may include a connector 100, a holder 200, a valve part 300, and an opening/closing part 400. The holder 200 is disposed at one end of the connector 100. The valve part 300 is disposed at the other end of the connector 100. The opening/closing part 400 is disposed between one end and the other end of the connector 100.

The connector 100 is a tubular member. Catheters 10 or drugs may flow through the connector 100. The holder 200 is connected to a hose (not shown). The holder 200 connects the hose and the connector 100. And the holder 200 communicates the hose and the connector 100. The holder 200 may be rotatably coupled to the connector 100. The valve unit 300 is a place to supply the catheter 10. Catheters 10 are inserted into the valve unit 300. The catheter 10 inserted into the valve part 300 passes through the holder 200 through the connector 100 and is inserted into a hose. The valve unit 300 serves to seal the channel of the connector 100 by selectively tightening the inlet through which the catheter 10 is introduced, while supplying the catheter 10 to the connector 100.

The connector 100 may be made of a transparent material so that the user can visually check the air bubbles in the channel.

While supplying the catheter 10 to the connector 100, the shape of the valve unit 300 for selectively tightening the inlet through which the catheter 10 is introduced may vary. For example, the valve unit 300 may be divided into a body 310 and a handle 320. The body 310 is connected to the connector 100. The handle 320 may be fastened to the body 310 so as to move upwardly. The body 310 may be rotatably coupled to the connector 100. Although not shown in the drawings, sealing members in which a through hole through which the catheter 10 passes through may be disposed inside the body 310. When the handle 320 moves up and down or the body 310 rotates, the sealing members are pressed or released, the sealing members are deformed, so that the through hole through which the catheter 10 passes is expanded or contracted.

2 is a side cross-sectional view of the connector 100 and the opening/closing part 400 shown in FIG. 1.

The hole 140 communicates with the channel 120 of the body 110. The hole 140 may be branched from the channel 120. The degassing pipe 130 is for discharging air bubbles present in the channel 120 to the outside. The degassing pipe 130 may protrude from the body 110.

The opening/closing part 400 may be disposed in the degassing pipe 130. The opening and closing part 400 selectively opens the hole 140. When the opening and closing part 400 opens the hole 140, bubbles existing in the channel 120 may be discharged to the outside through the hole 140. Since the pressure of the channel 120, in particular, the pressure on the side of the second end 110b connected to the blood vessel of the patient is higher than the atmospheric pressure, the bubbles present in the channel 120 do not flow to the side of the second end 110b, It is guided to the hole 140 and discharged to the outside. The opening/closing unit 400 may be operated by a user pressing, pushing, pulling, or turning. The operation of the opening and closing part 400 of the hemostatic valve device according to the embodiment is operated by a simple operation of the user. This greatly increases the repeatability and ease of the process of removing air bubbles during the procedure.

A concave groove 411 may be disposed on the upper surface of the sealing member 410. The groove 411 may be conical. The sealing member 410 may include a cutout portion 412. Although the shape of the cut-out part 412 is illustrated with a date, the present invention is not limited thereto, and the cut-out part 412 may be implemented to have various shapes such as a cross shape and a star shape. The conical groove 411 facilitates the expansion of the cutout 412. The cutout 412 may be disposed across the groove 411. An extended area 414 of the cutout 412 may be disposed at the center of the lower surface of the sealing member 410. An annular first groove 413 may be disposed on the upper surface of the sealing member 410. The annular first groove 413 is for coupling with the second member 430. These first grooves 413 increase the bondability and adhesion between the second member 430 and the sealing member 410.

An annular second groove 415 may be disposed on the lower surface of the sealing member 410. The second annular groove 415 is for coupling with the upper surface of the degassing pipe 130. This second groove 415 improves the coupling and adhesion between the degassing pipe 130 and the sealing member 410.

The sealing member 410 is made of an elastic material. When an external force acts on the sealing member 410, it is deformed. When the sealing member 410 is deformed, the cutout 412 is expanded or contracted. When the cutout 412 is expanded, the hole 140 is opened. Conversely, when the cutout 412 is reduced, the hole 140 is closed. When the cutout 412 is expanded, the air bubbles present in the hole 140 may be disposed outside the degassing pipe 130. When the sealing member 410 is deformed, the expansion area 414 of the cut-out part 412 is larger than the cut-out part 412, so that the air bubbles in the hole 140 can more easily penetrate the sealing member 410. To induce.

9 is a diagram illustrating the second member 430 shown in FIG. 3.

3 and 9, the second member 430 fixes the sealing member 410 to the degassing pipe 130. The inner surface of the second member 430 is in contact with the sealing member 410. In addition, the second member 430 guides the vertical movement of the first member 420. The second member 430 may be a cylindrical member. The second member 430 may include an upper surface 432 and a side surface 431. The second member 430 may be a member whose lower side is open. A through hole 431a may be disposed in the center of the second member 430. The tube 423 passes through the through hole 431a. The through hole 431a is aligned with the cutout 412 of the sealing member 410. The tube 423 passes through the through hole 431a and contacts the cutout 412. A protrusion 433 may be disposed on the side surface 431. The second member 430 is disposed inside the first member 420, and the protrusion 433 is disposed in the slot 425. When the protrusion 433 is caught on the sidewall of the slot 425, the vertical movement of the first member 420 is restricted. Meanwhile, a guide groove 434 may be disposed on the side surface 431. The second member 430 is disposed inside the first member 420, and the guide 426 is disposed in the guide groove 434. The guide groove 434 guides the vertical movement of the first member 420.

Referring to FIG. 2, the elastic member 440 may be disposed between the first member 420 and the second member 430 in the vertical direction. The elastic member 440 may be a member having a restoring force upon compression. For example, the elastic member 440 may be a compression coil spring.

Referring to FIG. 2, when there is no external force, the hole 140 is closed by the sealing member 410. By the restoring force of the elastic member 440, the first member 420 is disposed apart from the second member 430 until it is caught on the lower end of the slot 425. At this time, the tube 423 is in a state in which the sealing member 410 is not pressed.

10 is a side cross-sectional view of the connector 100 and the opening and closing portion 400 showing the flow of bubbles, and FIG. 11 is a front cross-sectional view of the connector 100 and the opening and closing portion 400 showing the flow of bubbles.

Referring to FIGS. 10 and 11, when air bubbles inside the channel 120 are checked during the procedure, the user presses the first member 420. When the first member 420 is pressed, the tube 423 moves downward and presses the incision 412. Thereafter, as the sealing member 410 is deformed, the cutout 412 is expanded, and the hole 140 and the tube 423 are communicated. The tube 423 is in an atmospheric pressure state because it is in communication with the outside through the connection hole 424. When the hole 140 and the tube 423 communicate, since the pressure of the channel 120 is higher than the pressure of the tube 423, the bubbles v existing in the channel 120 are introduced into the hole 140. Bubbles (v) introduced into the 140 are discharged to the outside through the tube 423 and the connection hole 424. When the user releases his or her hand from the first member 420, the first member 420 moves upward due to the restoring force of the elastic member 440, and when the first member 420 moves upward, the tube 423 By moving upward, the pressure on the sealing member 410 is released. When the pressure is released, the shape of the sealing member 410 is restored, and the cutout 412 is reduced so that the hole 140 is closed again.

The portion pressed by the user is the upper surface (421 of FIG. 7) of the first member 420. In addition, a portion in which the connection hole 424 is disposed is a side surface 422 of the first member 420. Therefore, since the user's hand, specifically, the contact area between the user's finger and the first member 420 and the discharge area of the bubble v are clearly separated so as not to interfere with each other, the bubble (v) can be discharged more smoothly. There is an advantage.

Using the embodiment, in the process of injecting the catheters 10 into the blood vessel, the user can remove the air bubbles v with only a simple operation. In addition, since the bubble (v) is removed by using the pressure difference between the inside and the outside of the connector 100, it is possible to effectively prevent the bubble (v) from flowing into the blood vessel. This greatly increases the success rate of the procedure. In addition, there is an advantage of significantly lowering the user's fatigue during the procedure.

In addition, the user can remove the bubbles (v) by simply pressing the opening and closing part 400 immediately when the bubbles (v) are confirmed while pushing the catheters (10), so that the bubbles (v) are removed. There is an advantage in that there is no need for a separate procedure to remove. In addition, since the user can remove the bubbles (v) alone, there is an advantage that no auxiliary manpower is required for removing the bubbles (v). In addition, rapid treatment is possible.

In addition, since it is easy to repeat the operation of removing the bubbles (v), it is possible to effectively prevent the bubbles (v) from flowing into the blood vessel. In addition, since it is possible to lower the skill level required of a practitioner, there is an advantage in that it is easy to secure a surgical manpower.
