Description

A dial-type tourniquet {A DIAL-TYPE TOURNIQUET}

The present invention relates to a tourniquet, and more particularly, to a dial-type tourniquet capable of tightening a tourniquet through a dial to enable rapid hemostasis and pressure control.

A tourniquet is intended to stop bleeding if bleeding occurs due to an accident or the like. Hemostasis is performed by directly pressing the bleeding site or compressing the area around it.

In the case of arteries, it is not easy to stop bleeding because of blood spattering. In the past, twisted tourniquets, such as a rod inserted between cloths, were used, or gauze was wrapped with a bandage to bleed the wound. In this case, there may be problems such as death due to excessive hemorrhage due to a hemostatic effect.

In order to solve such a problem, Korean Utility Model Registration No. 20-0381454 discloses a hemostatic belt for hemostasis by directly pressing a wound area by using the lifting and lowering of a pressing member.

There is a strong demand for a tourniquet that can perform a rapid, quick and efficient hemostasis over conventional tourniquets.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below.

Furthermore, embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings may be exaggerated for clarity of description, and the elements denoted by the same reference numerals in the drawings are the same elements.

The present invention relates to a dial type tourniquet capable of performing hemostasis quickly and simply and capable of finely adjusting the pressing strength.

1 is a perspective view of a dial type tourniquet according to one aspect of the present invention. 2 is a cross-sectional view taken along line AA 'in FIG. 3 is a side view after incorporating a dial-type tourniquet according to one aspect of the present invention.

1 to 3, a dial type tourniquet according to an aspect of the present invention includes a first tightening member 10, a second tightening member 20, and a second tightening member 20, which is rotated in one direction but does not rotate in the opposite direction And a dial-type tightening unit (30-33) of a one-way clutch type.

The first tightening member 10 may be in the shape of a band, and the width or length of the first tightening member 10 may be sufficient to sufficiently compress the wound site or its peripheral area in consideration of the wound site. The first tightening member 10 may be equipped with tie-type tightening units 30 to 33 as described later.

The first tightening member 10 is made of a material having a rigidity enough to mount the tightening units 30 to 33 and has flexibility enough to cover the wound area or its peripheral parts during hemostasis. As the material of the first tightening member 10, a fabric or plastic having both rigidity and flexibility can be used.

A first pressing belt (11) can be connected to the end of the first tightening member (10). The material of the first pressing belt is not particularly limited as long as it can cover the wound area or the peripheral area thereof and can sufficiently apply pressure. For example, fabric material or plastic can be used.

The first tightening member 10 and the first pressing belt may be made of the same material or may be integrally molded. For example, all fabric materials can be used. The cost can be reduced if the same material is used or if it is integrally molded.

At the end of the first pressing belt 11, a coupling hole 12 may be formed. The first pressing belt 11 and the second pressing belt 21 can be coupled through the coupling hole. For example, the velcro attaching portion 22 can be formed by performing a Velcro process on the end portion of the second pressing belt 21. After the Velcro attaching portion 22 is inserted into the fastening hole in the fastener, 22 can be folded and attached.

The second tightening member 20 may be in the shape of a band, and a groove penetrating the upper and lower portions may be formed long in the longitudinal direction. Teeth 23 are formed on one side member 20b in the longitudinal direction of the groove and teeth are not formed on the other side member 20a.

The teeth 23 formed in the groove portion of the second tightening member 20 can be engaged and engaged with the gear 32 of the tightening unit. When the gear wheel 32 of the tightening unit is rotated, the second tightening member 20 can be slid accordingly. This is similar to the operation principle of a rack-and-pinion gear. That is, when the toothed wheel 32 of the tightening unit rotates clockwise, the second tightening member 20 can slide to the left and move.

The second tightening member 20 is made of a material having a rigidity enough to withstand the stress generated by the movement of the teeth 23 and the toothed wheel 32. The second tightening member 20 is also made of a material It should also be flexible enough to cover it. As the material of the second tightening member 20, a fabric or plastic having both rigidity and flexibility can be used.

Particularly, FIG. 2 shows a sectional structure inside the housing 33. 2, one side member 20b of the second tightening member 20 is located on the right side of the gear wheel 32, teeth 23 are formed on the side member 20b, and the other side member 20a is formed on the left side. And there is no saw tooth.

The toothed wheel 32 of the tightening unit is engaged with the teeth 23 formed on the left side of the one member 20b. There is only a clearance between the right end of the one member 20b and the housing 33 so that sliding can be made. 2, the spacing between the right end of one member and the housing 33 is shown exaggerated for the sake of convenience.

On the other hand, in the case of the other member 20a, both the left end and the right end thereof may be sufficiently spaced apart from the housing 33 and the cog wheel 32, whereby the sliding of the second tightening member 20 is made more freely .

A second pressing belt 21 may be connected to the end of the second tightening member 20. The material of the second pressing belt 21 is not particularly limited as long as it can cover the wound area or its surrounding area and can press the wound area sufficiently. For example, fabric material or plastic can be used.

The second fastening member 20 and the second pressing belt 21 may be made of the same material or may be formed integrally with each other. For example, all fabric materials can be used. The cost can be reduced if the same material is used or if it is integrally molded.

The tightening units 30 to 33 may be composed of a housing 33 and fastening dials 30 to 32. The housing 33 is mounted on the first tightening member 10 and functions to guide the sliding movement of the second tightening member 20.

The housing 33 is open on both sides in the longitudinal direction of the first tightening member 10. For example, it may be a structure in which both longitudinal sides of the rectangular parallelepiped are openings. The second fastening member 20 is inserted into the opening and serves as a guide when the second fastening member 20 is slid.

The housing 33 should be mounted on the first tightening member 10 and fixed, and there should be no problems such as being separated during the hemostasis. The manner in which the housing 33 is mounted on the first tightening member 10 is not particularly limited. For example, after the first tightening member 10 penetrates, the end portion can be fixed by being bent or clamped.

The fastening dials 30 to 32 may include a gear 32, a shaft 31 and a dial knob 30. [

The fastening dials 30 to 32 can be mounted on the first tightening member 20 and fixed. The toothed wheel 32 of the tightening dial engages with the teeth 23 of the second tightening member 20. The gear wheel 32 of the tightening dial is connected to the dial knob 30 via the shaft 31. [

One-way clutches can be employed for transmitting the rotational force (power) only in one direction to the tightening dials 30 to 32 and revolving in the opposite direction. For example, the dial knob 30 may be a so-called ratchet structure that can transmit power when turning the dial knob 30 in the clockwise direction, but revolves without transmitting power when the dial knob 30 is turned in the opposite direction.

Specifically, when the dial knob 30 is turned clockwise, the force is transmitted to the second tightening member 20 through the toothed wheel 32 and the toothed wheel 23, so that the second tightening member 20 is slid to the left . Therefore, the tourniquet can be tightened and the hemostasis of the injured area can be induced.

If the ratio of the diameter of the dial knob 30 to the diameter of the cog wheel 33 is large, even if a relatively small force is applied, the hemostasis can be effected effectively. However, if the ratio is small, a relatively large force may be required have. Since the degree of compression required for hemostasis may vary depending on the body part, the above ratio can be appropriately adjusted for each site to be used.

Hereinafter, a method of operating the dial type tourniquet according to the present invention will be described in detail.

First, the dial-type tourniquet according to the present invention is located at or near the wound site. If you want to place it near the wound, place it near the heart.

Next, after the velcro attaching portion 22 of the second pressing belt is inserted into the engaging hole 12 of the first pressing belt, the velcro attaching portion 22 can be pulled firmly and folded and attached. This can be applied primarily to the wound area or the area around the wound. The pressing strength can be adjusted by adjusting the length of the Velcro attaching portion 22 passing through the fitting hole 12. It is desirable that such primary pressing is strong enough if possible. The second pressure through the dial is to ensure that even a slight increase in the degree of compression is sufficient.

Next, the dial knob 30 is turned clockwise to apply pressure to the wound area or the area around the wound. When the dial knob 30 is turned clockwise, the gear wheel 32 connected to the shaft 31 also rotates clockwise. The teeth 23 of the second tightening member engaged with the toothed wheel 32 are moved to the left side, thereby further increasing the pressing force. The operation of the toothed wheel 32 and the teeth 23 of the second tightening member is similar to the operation principle of the rack-and-pinion gear.

Since the fastening dials 30 to 32 are unidirectional clutches designed to rotate in the clockwise direction and not rotate in the opposite direction, it is possible to apply the continuous pressing by turning the dial knob 30 in the clockwise direction. Since the pressure is already applied enough at the primary pressure, the secondary pressure can exert a superior hemostatic effect even if the pressure is slightly increased.

Next, after the hemostasis is completed, the tourniquet can be removed from the wound site or its surrounding area by separating the Velcro attaching section 22.
