Description
Technical Field
[0001] The invention belongs to the technical field of medical devices, in particular to a portable hemostatic device. Background Art
[0002] During limb surgery, exsanguination and hemostasis are often required, and exsanguination and hemostasis devices are widely used. Exsanguination and hemostasis constriction rings are designed to meet clinical requirements and utilize the mechanical pressure of an elastic ring to exsanguinate and stop bleeding, suitable for limb surgery.
[0003] However, when elastic sleeves are directly used to stop bleeding, the sleeves need to be removed after the operation is completed. Generally, the sleeves pressed on the limbs are directly cut off with scissors or knives. Improper operation may easily cause damage to the human body. Therefore, existing hemostatic devices of this type have certain defects. Summary of the Invention
[0004] In order to make up for the shortcomings of the existing technology, the present invention proposes a convenient hemostatic device by using a gasket strip to guide and limit the cutting equipment during cutting, and to conveniently and safely remove the used hemostatic device.
[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: the portable hemostatic device of the present invention comprises an elastic shrink ring, an elastic sleeve and a ribbon, the elastic sleeve and the ribbon are wound around the elastic shrink ring by rolling from the end, a handle is installed at the end of the ribbon, and the end of the elastic sleeve is tied with a tie;
[0006] The elastic knitted sleeve and the elastic shrink ring are set on the patient's limb to be hemostatic;
[0007] It also includes a gasket strip, which is attached to the surface of the elastic knitting sleeve, and is located between the elastic knitting sleeve and the surface of the limb, and at least two gasket strips are evenly distributed along the circumference of the elastic shrink ring;
[0008] The gasket strip is made of elastic plastic material, and the gasket strip and the elastic sleeve are wound together on the elastic shrink ring;
[0009] A guide groove is provided on the surface of the gasket strip, the opening of the guide groove faces the elastic knitted sleeve, the cross section of the guide groove is triangular, and the guide groove is arranged obliquely relative to the surface of the gasket strip.
[0010] Preferably, a slit groove is provided on the surface of the gasket strip away from the elastic sleeve, and the slit groove is in an expanded state when the gasket strip is wound around the elastic shrink ring.
[0011] Preferably, a silicone layer is installed on the gasket strip, the silicone layer is located on the surface of the gasket strip away from the elastic sleeve, and the slit groove passes through the silicone layer.
[0012] Preferably, a raised strip is installed on the silicone layer, the length direction of the raised strip is perpendicular to the length direction of the gasket strip, and the length of the raised strip is greater than the width of the silicone layer.
[0013] Preferably, the raised strips include rod-shaped strips and annular strips, and the annular strips are evenly distributed along the length direction of the gasket strip.
[0014] Preferably, the surfaces of the annular strips, rod-shaped strips and silicone layer are roughened.
[0015] Preferably, an air cavity is provided inside the annular strip, and the air cavity is inflated after being pierced by a syringe needle.
[0016] The beneficial effects of the present invention are as follows:
[0017] 1. The portable hemostatic device described in the present invention has a gasket strip and a guide groove, so that the staff can directly insert a scalpel into the guide groove and cut the elastic sleeve and the elastic shrink ring along the guide groove, so as to quickly, conveniently and safely remove the hemostatic device. The inclined guide groove relatively increases the thickness of the gasket strip, avoiding the scalpel from cutting through the gasket strip and scratching the patient's limbs. At the same time, the gasket strip and the elastic sleeve are integrated into a whole, avoiding the problem of the gasket strip being an independent accessory and being easily lost or dropped. In addition, when removing the hemostatic device, the staff does not need to install the gasket strip additionally, which is convenient and quick.
[0018] 2. The portable hemostatic device described in the present invention increases the effect of the elastic sleeve on repelling blood and stopping bleeding in the soft tissue of the limbs by providing raised strips, annular strips and air cavities, thereby preventing the thickness of the gasket strips from forming gaps between the elastic sleeve and the skin, thereby affecting the hemostatic effect. At the same time, the expansion of the annular strips and the air cavity will enhance the hemostatic effect on the limbs, and at the same time, will increase the friction between the elastic sleeve and the limbs, thereby preventing the elastic sleeve from creeping and shrinking due to changes in the thickness of the limbs and the movement of the limbs.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0028] like Figures 1 to 6 As shown, the portable hemostatic device of the present invention comprises an elastic shrink ring 1, an elastic sleeve 3 and a ribbon 2. The elastic sleeve 3 and the ribbon 2 are wound around the elastic shrink ring 1 by rolling from the end. A handle 4 is installed at the end of the ribbon 2. The end of the elastic sleeve 3 is tied with a tie 5.
[0029] The elastic knitted sleeve 3 and the elastic shrink ring 1 are placed on the patient's limb to be hemostatic;
[0030] It also includes a gasket strip 6, which is attached to the surface of the elastic sleeve 3 and is located between the elastic sleeve 3 and the surface of the limb. At least two gasket strips 6 are evenly distributed along the circumference of the elastic shrink ring 1;
[0031] The gasket strip 6 is made of elastic plastic material, and the gasket strip 6 and the elastic sleeve 3 are wound together on the elastic shrink ring 1;
[0032] During use, the end of the limb to be hemostatic is passed through the hole of the elastic shrink ring 1. After that, the staff first holds the patient's limb and then pulls the ribbon 2 through the handle 4 to make the elastic shrink ring 1 roll along the limb, driving the elastic sleeve 3 to cover the limb. After that, the ribbon 2 is cut after the elastic shrink ring 1 reaches the designated position on the patient's limb. After that, the elastic sleeve 3 at the designated position is cut off to expose the surgical incision on the limb.
[0033] At the same time, when the elastic sleeve 3 is covered on the limb, the gasket strip 6 attached to the elastic sleeve 3 will be unwound from the elastic shrink ring 1 along with the covering of the elastic sleeve 3, and will be pressed against the skin 7 on the surface of the limb by the elastic sleeve 3;
[0034] When the elastic shrink ring 1 rolls along the limb, the mechanical pressure of the elastic shrink ring 1 will drive away the blood. Then, the pressure of the elastic sleeve 3 will block the blood flow in the limb artery, achieving the effect of driving away blood and stopping bleeding.
[0035] At the same time, after the operation is completed, since there is a gasket strip 6 between the elastic sleeve 3 and the skin 7, the staff can directly slide and cut along the gasket strip 6 with a scalpel or other sharp cutting equipment, quickly and conveniently cut off the elastic sleeve 3 and the elastic shrink ring 1, and remove the hemostatic device;
[0036] At the same time, the gasket strip 6 is used to support the cutting scalpel, so that the staff can directly cut the elastic sleeve 3 and the elastic shrink ring 1 with the scalpel, which facilitates the removal of the hemostatic device and improves the removal speed;
[0037] At the same time, when the scalpel cuts the elastic shrink ring 1 and the elastic sleeve 3, the tip of the scalpel will slide along the surface of the gasket strip 6, so that the gasket strip 6 can be used to guide and position the blade of the scalpel, thereby preventing the scalpel from being pressed down too hard or deviating during sliding, causing the blade to scratch the limbs, causing additional damage to the patient and increasing pain;
[0038] At the same time, since the gasket strip 6 is attached to the elastic sleeve 3 and is pressed against the surface of the skin 7 by the elastic sleeve 3, the gasket strip 6 and the elastic sleeve 3 are integrated, so that the staff can directly use a scalpel to cut along the surface of the gasket strip 6 and remove the hemostatic device, without the need to use other tools or removal accessories that come with the hemostatic device, such as a plastic plate, thereby avoiding the loss or dropping of plastic accessories. At the same time, since the gasket strip 6 is pressed and fixed by the elastic sleeve 3, it can also avoid the gasket strip 6 from being displaced when the blade cuts the elastic sleeve 3 and the elastic shrink ring 1, resulting in scratches on the limbs.
[0039] A guide groove 61 is provided on the surface of the gasket strip 6, the opening of the guide groove 61 faces the elastic sleeve 3, the cross section of the guide groove 61 is triangular, and the guide groove 61 is inclined relative to the surface of the gasket strip 6;
[0040] Insert the blade of the scalpel tip into the guide groove 61, so that the scalpel is accurately guided and limited when sliding along the surface of the gasket strip 6 and cutting the elastic sleeve 3 and the elastic shrink ring 1, thereby preventing the scalpel blade from slipping off the gasket strip 6 due to shaking of the hand of the staff holding the knife or shaking of the patient's limbs when removing the hemostatic device, thereby preventing the blade from scratching the patient's limbs.
[0041] At the same time, since the guide groove 61 is arranged obliquely, after the blade of the scalpel tip is inserted into the guide groove 61, the scalpel will be inclined relative to the surface of the gasket strip 6, so that the thickness of the gasket strip 6 in the direction where the tip of the scalpel points to the patient's limb increases, making it more difficult for the scalpel blade to cut through the gasket strip 6, and preventing the scalpel tip from vertically contacting the gasket strip 6, resulting in the scalpel cutting through the gasket strip 6 and scratching the patient's limb;
[0042] At the same time, through the inclined guide groove 61, the oblique thickness of the gasket strip 6 is used to replace the thickness in the vertical direction, so that the gasket strip 6 with a smaller thickness when the scalpel is inclined and the gasket strip 6 with a larger thickness when the scalpel is vertical have the same effect, that is, the gasket strip 6 with a smaller thickness can be used to replace the gasket strip 6 with a larger thickness, so that the gasket strip 6 is conveniently attached and installed on the elastic sleeve 3, and is wound around the elastic shrink ring 1 together with the elastic sleeve 3, avoiding the gasket strip 6 having a larger thickness and affecting the winding of the elastic sleeve 3 on the elastic shrink ring 1.
[0043] As an embodiment of the present invention, a slit groove 62 is formed on the surface of the gasket strip 6 away from the elastic sleeve 3, and the slit groove 62 is in an expanded state when the gasket strip 6 is wound on the elastic shrink ring 1;
[0044] Since the gasket strip 6 is provided with a slit groove 62, when the gasket strip 6 is wound onto the elastic shrink ring 1 together with the elastic sleeve 3, the slit groove 62 on the gasket strip 6 will change from a state of close contact to an expanded state, thereby reducing the elastic force required during the winding process of the gasket strip 6, and preventing the gasket strip 6 from having an excessive elastic force to restore to its original shape after winding, resulting in separation of the gasket strip 6 at the end of the elastic sleeve 3, affecting the normal use of the hemostatic device;
[0045] At the same time, by opening a slit groove 62 on the gasket strip 6, the thickness of the gasket strip 6 at the slit groove 62 and perpendicular to the gasket strip 6 is relatively small. Therefore, after the hemostatic device is covered on the limb, the staff can use a scalpel to cut the gasket strip 6 at the slit, thereby facilitating the cutting of the local elastic sleeve 3 to expose the surgical incision.
[0046] As an embodiment of the present invention, a silicone layer 63 is installed on the gasket strip 6, and the silicone layer 63 is located on the surface of the gasket strip 6 away from the elastic sleeve 3, and the slit groove 62 passes through the silicone layer 63;
[0047] Since the hardness of the gasket strip 6 is relatively greater than the skin on the limb, and the gasket strip 6 is re-stretched from the state of being wrapped around the elastic shrink ring 1 and attached to the surface of the limb, the slit grooves 62 on the gasket strip 6 will gradually shrink and fit together. During this process, it is easy for the skin 7 on the surface of the limb to be embedded in the slit grooves 62 and squeezed by the slit grooves 62. Therefore, a silicone layer 63 is provided on the gasket strip 6, and the silicone layer 63 is used to isolate the gasket strip 6 from the skin 7 on the surface of the limb to avoid the slit grooves 62 squeezing the embedded skin 7 when the gasket strip 6 is attached to the surface of the skin 7.
[0048] As an embodiment of the present invention, a raised strip 64 is installed on the silicone layer 63, the length direction of the raised strip 64 is perpendicular to the length direction of the gasket strip 6, and the length of the raised strip 64 is greater than the width of the silicone layer 63;
[0049] Due to the thickness of the gasket strip 6 and the silicone layer 63 required to achieve the breeding effect, when the elastic sleeve 3 presses the gasket strip 6 against the surface of the skin 7 on the limb, gaps will appear on both sides of the elastic sleeve 3 near the gasket strip 6 in the width direction, forming gap areas 8. As a result, the squeezing force of the elastic sleeve 3 in the area where the gap areas 8 are located on the limb is relatively small, thereby affecting the effect of repelling blood from the soft tissue of the limb, resulting in the hemostatic effect of the hemostatic device being affected.
[0050] Since the silicone layer 63 is provided with a raised strip 64 and the length of the raised strip 64 is greater than the width of the silicone layer 63, when the elastic sleeve 3 presses the gasket strip 6 against the surface of the limb, the raised strip 64 on the silicone layer 63 will pass through the gap area 8, and drive away and block the blood in the soft tissue corresponding to the gap area 8 on the limb, thereby ensuring the hemostatic effect of the hemostatic device.
[0051] As an embodiment of the present invention, the raised strips 64 include rod-shaped strips and annular strips 65, and the annular strips 65 are evenly distributed along the length direction of the gasket strip 6;
[0052] After the elastic sleeve 3 is covered on the limb, the annular strips 65 are set to compress and block the soft tissue on the limb multiple times to prevent blood from flowing in the soft tissue. Therefore, even if there is blood that has not been completely expelled from the soft tissue in the area covered by the elastic sleeve 3 on the limb or the elastic shrink ring 1 has a poor effect in expelling and blocking blood in the limb, it can still ensure a good hemostatic effect on the limb and reduce the amount of bleeding in the surgical area on the limb.
[0053] As an embodiment of the present invention, the surfaces of the annular strip 65, the rod-shaped strip, and the silicone layer 63 are roughened;
[0054] By setting the raised strips 64 and the silicone layer 63, after the gasket strip 6 is pressed onto the surface of the skin 7 on the limb by the elastic sleeve 3, the friction between the gasket strip 6 and the skin 7 on the surface of the limb is relatively large, and the gasket strip 6 will not undergo relative displacement, thereby preventing the elastic sleeve 3 from wriggling and wrinkling on the patient's limb when the thickness of the patient's limb covered by the elastic sleeve 3 changes greatly or the patient's limb movements are relatively frequent, thereby affecting the working effect of the hemostatic device and interfering with the exposed surgical area on the limb.
[0055] As an embodiment of the present invention, an air cavity 651 is formed inside the annular strip 65, and the air cavity 651 is inflated after being pierced by a syringe needle;
[0056] When the hemostatic effect on the limb is poor or the patient's limb movements are relatively frequent, the staff will directly insert the needle of the syringe into the air cavity 651, thereby injecting air into the air cavity 651 to expand the annular strip 65, increase the pressure of the annular strip 65 on the limb, and thus improve the hemostatic effect;
[0057] At the same time, after the air cavity 651 is inflated and the annular strip 65 expands, the force exerted by the annular strip 65 on the limb also increases, further increasing the friction between the annular strip 65 and the limb, preventing the elastic sleeve 3 from sliding or shrinking on the limb, affecting the normal use of the hemostatic device.
[0058] The specific workflow is as follows:
[0059] During use, the end of the limb to be hemostatic is passed through the hole of the elastic shrink ring 1. After that, the staff first holds the patient's limb and then pulls the ribbon 2 through the handle 4 to make the elastic shrink ring 1 roll along the limb, driving the elastic sleeve 3 to cover the limb. After that, the ribbon 2 is cut after the elastic shrink ring 1 reaches the designated position on the patient's limb. After that, the elastic sleeve 3 at the designated position is cut off to expose the surgical incision on the limb.
[0060] At the same time, when the elastic sleeve 3 is covered on the limb, the gasket strip 6 attached to the elastic sleeve 3 will be unwound from the elastic shrink ring 1 along with the covering of the elastic sleeve 3, and will be pressed against the skin 7 on the surface of the limb by the elastic sleeve 3;
[0061] After the operation is completed, since there is a gasket strip 6 between the elastic sleeve 3 and the skin 7, the staff can directly slide and cut along the gasket strip 6 with a scalpel or other sharp cutting equipment, quickly and conveniently cut off the elastic sleeve 3 and the elastic shrink ring 1, and remove the hemostatic device;
[0062] The tip of the scalpel will slide along the surface of the gasket strip 6, and the gasket strip 6 will be used to guide and position the blade of the scalpel;
[0063] Insert the blade of the scalpel tip into the guide groove 61, so that the scalpel slides along the surface of the gasket strip 6 and is accurately guided and limited when cutting the elastic sleeve 3 and the elastic shrink ring 1;
[0064] Since the guide groove 61 is arranged at an angle, after the blade of the scalpel tip is inserted into the guide groove 61, the scalpel will be inclined relative to the surface of the gasket strip 6, so that the thickness of the gasket strip 6 in the direction where the tip of the scalpel points to the patient's limb increases, making it more difficult for the blade of the scalpel to cut through the gasket strip 6;
[0065] At the same time, by means of the oblique guide groove 61, the oblique thickness of the gasket strip 6 is used to replace the thickness in the vertical direction, so that the gasket strip 6 with a smaller thickness when the scalpel is inclined and the gasket strip 6 with a larger thickness when the scalpel is vertical can play the same role, that is, the gasket strip 6 with a smaller thickness can replace the gasket strip 6 with a larger thickness, thereby facilitating the gasket strip 6 to be attached to the elastic sleeve 3 and wound around the elastic shrink ring 1 together with the elastic sleeve 3;
[0066] Since the gasket strip 6 is provided with a slit groove 62, when the gasket strip 6 is wound onto the elastic shrink ring 1 together with the elastic sleeve 3, the slit groove 62 on the gasket strip 6 changes from a state of close contact to an expanded state, thereby reducing the elastic force required during the winding process of the gasket strip 6;
[0067] At the same time, by providing a slit groove 62 on the gasket strip 6, the thickness of the gasket strip 6 at the slit groove 62 and in a direction perpendicular to the gasket strip 6 is relatively small. Therefore, after the hemostatic device is covered on the limb, the staff can use a scalpel to cut the gasket strip 6 at the slit, making it easier to cut off the local elastic sleeve 3 to expose the surgical incision.
[0068] A silicone layer 63 is provided on the gasket strip 6 to isolate the gasket strip 6 from the skin 7 on the limb surface, thereby preventing the slit groove 62 from squeezing the embedded skin 7 when the gasket strip 6 is attached to the skin 7.
[0069] Because the silicone layer 63 is provided with raised strips 64, and the length of the raised strips 64 is greater than the width of the silicone layer 63, when the elastic sleeve 3 presses the gasket strip 6 against the surface of the limb, the raised strips 64 on the silicone layer 63 will pass through the gap area 8, thereby driving away and blocking the blood in the soft tissue corresponding to the gap area 8 on the limb.
[0070] After the elastic sleeve 3 is covered on the limb, the annular strips 65 are provided to compress and block the soft tissue on the limb multiple times, thereby preventing blood from flowing in the soft tissue. Thus, even if there is blood that has not been completely expelled from the soft tissue in the area covered by the elastic sleeve 3 on the limb or the elastic shrink ring 1 is not effective in expelling and blocking blood in the limb, a good hemostatic effect on the limb can be ensured.
[0071] The raised strips 64 and the silicone layer 63 ensure that when the spacer strip 6 is pressed against the skin 7 on the limb by the elastic sleeve 3, the friction between the spacer strip 6 and the skin 7 on the limb surface is relatively large, and the spacer strip 6 will not move relative to the limb. This prevents the elastic sleeve 3 from creeping or shrinking on the patient's limb when the thickness of the limb covered by the elastic sleeve 3 varies greatly or the patient's limb moves frequently.
[0072] When the hemostatic effect of the limb is poor or the patient's limb movements are relatively frequent, the staff will directly insert the needle of the syringe into the air cavity 651, thereby injecting air into the air cavity 651 to expand the ring strip 65 and increase the pressure of the ring strip 65 on the limb;
[0073] At the same time, after the air cavity 651 is inflated and the annular strip 65 expands, the force of the annular strip 65 on the limb also increases, further increasing the friction between the annular strip 65 and the limb, preventing the elastic sleeve 3 from sliding or shrinking on the limb.
