Abstract

The present invention relates to a pressing-type multi-hemostasis device including: one or more hemostasis units which are attached in multiple stages between a hemorrhage area and a heart and prevents bleeding on the hemorrhage area by pressing; and a blood pressure measuring unit. The hemostasis unit adjusts a pressing degree according to blood pressure measured by the blood pressure measuring unit. According to the present invention, pain during hemostasis is reduced by dispersing excessive pressure, which can be generated when hemostasis is performed by one hemostasis unit, because the pressing-type multi-hemostasis device includes multiple hemostasis units. Furthermore, the multiple hemostasis units, arranged in multiple stages, sequentially performs hemostasis at different degrees of pressure so that necrosis, resulted from excessive pressure, of cells around the hemorrhage area can be prevented. Moreover, the pressing-type multi-hemostasis device can efficiently perform hemostasis because the volume of blood flow around the hemostasis units, attached to areas close to the hemorrhage area, is smaller when compared to the volume of blood flow of one hemostasis unit as the multiple hemostasis units disperse pressure. Blood pressure can be more stably monitored because influence from change of blood pressure by hemorrhage is less as the hemostasis unit is attached on an area other than the hemorrhage area. A user can immediately determine whether blood transfusion should be performed by a warning sign or sound at diastolic blood pressure of 80 mmHg. In addition, the pressing-type multi-hemostasis device can periodically measure blood pressure and can adjust a pressing degree of hemostasis manually or automatically. Therefore, the pressing-type multi-hemostasis device can prevent complications, which can occurs after hemostasis for a long time.

Description

[0001] COMPRESSIVE MULTIPLE TOURNIQUET DEVICE [0002]

The present invention relates to a compression type multi-hemostatic device having at least one hemostatic portion which is attached in a multi-stage between a bleeding portion and a heart to prevent bleeding from a bleeding portion through compression, and the degree of compression of the hemostatic portion is controlled according to the measured blood pressure.

In the year, about 95,000 workers suffered industrial accidents. 10% of the injuries occurring at the work site are caused by cutting, lumbar puncture, and stabbing. In the case of hand injuries, quick and accurate first aid treatment will determine the success of resin joint surgery. Therefore, it is necessary to bleed the patient more rapidly than in the case of an emergency where the extremity is severed.

As a hemostatic method, mainly a compression hemostatic device is used. This can be classified into a method of fixing the pressing member using a pneumatic or velcro material or a band which is pressed by using the air pressure.

Conventional compression hemostatic devices are limited to the first stage of the hemostasis cuff, and excessive pressure on the hemostasis site is causing the sufferer to suffer severe and effective hemostasis.

In addition, in the case of the Velcro fastening means of the cuff, both ends of the cuff are attached and detached, and the more the use is repeated, the weaker the binding force is. In the case of the Velcro tape with weak bonding force, when the air is inflated, the adhered portion of the vascular tape is dropped by the expansion force, so that the compression effect of the blood vessel is lowered, and in the worst case, both ends are separated.

In addition, during the transit of the patient or during the operation, hemostasis is required for about 30 minutes to 2 hours. In the long term hemostasis, secondary symptoms such as hypotensive shock, hypothermia, . Therefore, a skilled medical practitioner has to constantly monitor the blood pressure of the patient to judge the degree of transfusion and periodically adjust the degree of pressure in consideration of the state of the disease.

In the present invention, a plurality of hemostatic portions attached to a bleeding portion are configured to mitigate the suffering of a patient through pressure dispersion of a hemostatic portion and enable efficient hemostasis.

In addition, we aim to minimize secondary complications such as shock and skin necrosis caused by hypotension during prolonged hemostasis.

In addition, we would like to be able to determine immediately whether blood transfusion occurs during excessive bleeding.

In addition, both ends of the hemostasis portion are firmly connected to each other to enhance the compression effect.

The present invention relates to a compression type multi-hemostatic device in which the degree of compression of one or more hemostatic parts is selectively controlled according to a measured blood pressure, and more particularly, to a compression hemostatic device having multiple hemostatic parts between a bleeding part and a heart, And a blood pressure measuring unit for measuring the blood pressure of the patient at the hemostasis unit and the hemostasis.

The at least one hemostatic part of the present invention includes a pressure sensor, and is attached to the periphery of the bleeding part and presses inward, and the degree of compression is controlled according to the blood pressure measured by the blood pressure measurement part.

The hemostatic part of the present invention can be formed into a cylindrical shape, and a pupil through which a bleeding part such as an arm or a leg can pass is formed inside the cylindrical part.

In another embodiment of the present invention, the hemostatic portion may be formed in a curved band shape that is wound around the hemostatic portion. In this case, the hemostatic portion of the band-shaped hemostatic portion may be combined with each other through mutually detachable coupling means provided at both ends, .

The at least one hemostatic part of the present invention includes a first hemostatic part and a second hemostatic part, and may further include an additional hemostatic part. The second hemostatic portion is attached closer to the heart than the first hemostatic portion. Additionally, the third hemostatic part may be additionally attached in the cardiac direction to the second hemostatic part.

At this time, the degree of compression of the second hemostatic portion is set to 50% to 70% of the degree of compression of the first hemostatic portion. If the third hemostatic portion is attached, the degree of compression of the third hemostatic portion may be set to be lower than the degree of compression of the second hemostatic portion. In addition, the extent of compression of the first hemostat is not changed, and the degree of compression of the second and third hemostat is alternately changed over time.

In the present invention, the bleeding part to which the hemostasis part is attached is an arm or a leg, and the blood pressure measurement part of the present invention is attached to an arm, a leg, or a finger other than the bleeding part for accurate measurement of the blood pressure parameter. In other words, since the blood pressure of the arm or leg of the bleeding part may be inaccurate due to bleeding, the blood pressure measuring part may be attached to a body part capable of measuring blood pressure outside the bleeding part, .

The present invention is characterized in that, based on the blood pressure parameter measured by the blood pressure measuring unit, And a control unit for determining an air quantity parameter. The air pump for sucking or discharging air according to the air amount parameter may be included in the hemostatic part or included in the control part.

The control unit may receive the pressure parameter transmitted from the pressure sensor of the hemostasis unit.

In a preferred embodiment, the control unit sets the air parameter of the second hemostasis unit so that the pressure parameter of the second hemostasis unit is 50% to 70% of the pressure parameter of the first hemostasis unit, based on the current pressure parameter of the received first hemostasis unit Increase or decrease. The second hemostatic portion expanded cuff is expanded or contracted by the air amount parameter, and the second hemostatic portion is set to 50% to 70% of the degree of compression of the first hemostatic portion.

Wherein the control unit increases the air amount parameter of at least one hemostasis unit by increasing the air supplied to at least one hemostasis unit when the blood pressure parameter measured by the blood pressure measurement unit is 0 mmHg to 80 mmHg and increases the air amount of at least one hemostatic unit when the blood pressure parameter is 120 mmHg or more Thereby selectively reducing the air supplied to the at least one hemostatic portion. That is, the control unit controls the air amount parameter of at least one hemostatic unit so that the blood pressure parameter during hemostasis is maintained at 80 mmHg to 120 mmHg.

The control unit includes a display unit and an alarm unit for visually displaying a blood pressure parameter measured by the blood pressure measuring unit or an air amount parameter and a pressure parameter supplied to the hemostatic unit. When the blood pressure parameter measured by the blood pressure measuring unit is 0 mmHg to 80 mmHg, the alarm unit transmits an alarm signal to the outside acoustically or visually.

According to the present invention, since the hemostatic portion is composed of a plurality of hemostatic portions, excessive pressure that may occur when hemostasis is caused by one hemostatic portion is dispersed to reduce pain upon hemostasis.

Furthermore, according to the present invention, since a plurality of hemostatic portions formed in a multi-stage are hemostatic in succession at different pressures, it is possible to prevent necrosis of cells around the bleeding site due to excessive pressure.

Further, since a plurality of hemostatic portions formed in a multi-stage are dispersed in pressure, it is possible to perform efficient hemostasis because the blood circulation around the hemostasis portion attached to the proximal hemostasis portion is smaller than when hemostasis is performed with one hemostatic portion.

In addition, since the blood pressure measuring part is attached to a part other than the bleeding part, blood pressure can be monitored stably due to relatively less influence on the blood pressure change due to bleeding, and blood pressure can be monitored stably in a relaxed blood pressure (80 mmHg) It is possible to immediately judge whether or not the operation is performed.

In addition, the blood pressure can be measured periodically, and the degree of compression of the hemostasis can be automatically adjusted in response to the change in blood pressure, thereby minimizing secondary complications that may occur during long-term hemostasis.

Further, when the hemostasis portion is formed in a band shape, the hemostatic portion is firmly coupled to the hemostatic portion by using a method of fixing the hemostatic portion by pressing one end of the hemostatic portion to the other side to strengthen the durability of the hemostatic portion.

Fig. 5 shows the difference in degree of compression of the first and second hemostatic parts 101 and 103. Fig. In one embodiment, the inflation cuff 105 (a) of the first hemostat 101 is inflated to a maximum pressure at which bleeding stops. The degree of expansion is preferably expanded to a pressure of 300 mmHg. The expansion cuff 105 (b) of the second hemostatic part 103 is preferably inflated to a pressure of 150 mmHg to 210 mmHg, which is 50% to 70% of the degree of compression of the first hemostatic part. More specifically, when the inflated cuff 105 (a) of the first hemostatic part 101 expands to a pressure (300 mmHg) leading to hemostasis, 1 Receive the pressure parameter (300mmHg) of the hemostatic part. The controller 30 calculates a pressure parameter (150 mmHg to 210 mmHg) of the second hemostat part 103 of 50% to 70% based on the pressure parameter of the received first hemostat. The control unit 30 receives the pressure parameter from the pressure sensor of the second hemostat 103 and determines that the pressure parameter of the received second hemostatic unit reaches the calculated pressure parameter of the second hemostatic unit (150 mmHg to 210 mmHg) And calculates an air quantity parameter of the second hemostatic portion. 3) connected to the second hemostatic part 103 sucks or discharges the air and the inflation cuff 105 (b (FIG. 3) of the second hemostatic part 103) ) Expands to 50% to 70% of the inflation cuff of the first hemostatic part 101.

6 shows a state of the hemostatic portion 10 attached to the leg portion. The wearing position of one or more hemostats 10 is attached to the proximal portion of the hemostasis portion 40 while the first hemostatic portion 101 is attached to the proximal portion of the bleeding portion 40 and the second hemostatic portion 103 is attached to the first hemostatic portion 101, Which is closer to the heart. Although not shown in the figure, when the third hemostatic portion is attached, it is attached closer to the heart than the second hemostatic portion. The blood pressure measuring unit 20 can be worn on a leg or an arm other than the bleeding part 40.

Best Mode for Carrying Out the Invention Hereinafter, preferred embodiments of the multi-hemostatic device according to the present invention will be described with reference to Figs. The first hemostatic part 101 worn on the proximal part of the bleeding part 40 in the direction of the initial heart is inflated with the inflation cuff 105 (a) of the first hemostatic part 101 under the pressure leading to the initial hemostasis. The inflated cuff 105 (a) is inflated by sucking air from the air pump 301 (a) to which the first bleeding part is connected. The air pump 301 (a) sucks or discharges air according to the air quantity parameter determined by the controller 30. [ The control unit 30 can determine the air quantity parameter of the first hemostatic unit from the user by the button unit 307 and reach the pressure that causes hemostasis. In this case, as described above, the pressure that leads to hemostasis can be 300 mmHg. When the inflated cuff 105 (a) of the first hemostat 101 is inflated to a pressure that causes hemostasis, the inflated cuff 105 (b) of the second hemostat 103 is controlled by the control unit Expand to 50% to 70% of the inflation cuff of the first hemostat 101. In this case, the pressure of the inflation cuff 105 (b) of the second hemostat part 103 may be 150 mmHg to 210 mmHg in the above-described process (see FIG. 5). When the third hemostatic portion is provided, the third hemostatic portion is set to 50% to 70% of the degree of compression of the first hemostatic portion 101, and the degree of compression of the second hemostatic portion 103 is set to the third May be set higher than the degree of compression of the hemostasis portion and lower than the degree of compression of the first hemostasis portion. In addition, the degree of compression of the second and third bleeding portions except the first bleeding portion can be alternately changed over time through the control unit 30. [ Through the procedure described above, at least one hemostatic portion bleeds to a dispersed pressure.

After the above process, the blood pressure measuring part 20 is attached to an arm or leg other than the bleeding part 40. Since the blood pressure measuring part is attached to a part other than the bleeding part, the influence on the blood pressure change due to the bleeding is relatively less and the blood pressure can be monitored stably. The blood pressure measuring unit 20 repeats the blood pressure measurement process so that continuous blood pressure measurement can be performed without manual operation of the user. The control unit 30 receives the highest, lowest, average blood pressure parameters and pulse rate measured by the blood pressure measuring unit. The control unit (30) determines the air quantity parameter of one or more hemostasis unit (10) based on the blood pressure parameter measured by the blood pressure measurement unit (20). More specifically, when the blood pressure parameter measured by the blood pressure measuring unit is 0 mmHg to 80 mmHg, the control unit 30 increases the air amount parameter of at least one hemostatic unit 10 to increase the air supplied to the at least one hemostatic unit 10 And reduces the air amount parameter of the at least one hemostatic portion 10 when the blood pressure parameter is equal to or greater than 120 mmHg, thereby reducing the air supplied to the at least one hemostatic portion 10. [ Thus, the air volume parameter of the at least one hemostatic portion 10 is controlled so that the blood pressure parameter during hemostasis is maintained between 80 mmHg and 120 mmHg. The increase and decrease in air parameter of the at least one hemostatic part 10 according to the blood pressure parameter commonly acts on at least one hemostatic part 10 such that the inflatable cuff 105 of the at least one hemostatic part 10 is swollen, Shrink. Therefore, the above-mentioned second hemostatic part 103 is still maintained at 50% to 70% of the degree of compression of the first hemostatic part 101. [

Further, the control of the air quantity parameter of the at least one hemostatic part 10 according to the blood pressure parameter can be manually operated by the user through the button part 307. [

During the blood-clotting process, the alarm unit 305 transmits an alarm signal to the outside acoustically or visually when the blood pressure parameter measured by the blood pressure measuring unit 20 is 0 mmHg to 80 mmHg.
