Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and specifically relates to a portable blood driving and hemostasis device. Background Art

[0002] During limb surgeries, blood driving and hemostasis are often required, and blood driving and hemostasis devices are widely used. The blood driving and hemostasis contraction ring product combines clinical usage requirements and uses the mechanical pressure of an elastic ring to drive blood and stop bleeding, and is used in limb surgeries.

[0003] However, directly using an elastic sleeve to achieve blood driving and hemostasis requires removing the sleeve after the surgery. Generally, scissors or knives are directly used to cut the sleeve pressed on the limb, and improper operation is likely to damage the human body. Therefore, existing such blood driving and hemostasis devices have certain defects. Summary of the Invention

[0004] To make up for the deficiencies of the prior art, and to guide and limit the cutting equipment during cutting with a gasket strip, and to safely and conveniently remove the used blood driving and hemostasis device, the present invention provides a portable blood driving and hemostasis device.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: A portable blood driving and hemostasis device of the present invention includes an elastic contraction ring, an elastic sleeve, and a color strip. The elastic sleeve and the color strip are wound around the elastic contraction ring by rolling starting from the end. A handle is installed at the end of the color strip, and the end of the elastic sleeve is tied with a tie; The elastic sleeve and the elastic contraction ring are sleeved on the limb of the patient to be hemostatic; It further includes a gasket strip. The gasket strip is attached to the surface of the elastic sleeve. The gasket strip is located between the elastic sleeve and the limb surface. At least two gasket strips are evenly distributed along the circumferential direction of the elastic contraction ring; The gasket strip is made of an elastic plastic material, and the gasket strip is wound around the elastic contraction ring together with the elastic sleeve; A guiding groove is formed on the surface of the gasket strip. The opening of the guiding groove faces the elastic sleeve. The cross-section of the guiding groove is triangular, and the guiding groove is inclined relative to the surface of the gasket strip.

[0006] Preferably, a cutting slot is formed on the surface of the gasket strip away from the elastic sleeve. The cutting slot is in an expanded state when the gasket strip is wound around the elastic contraction ring.

[0007] Preferably, a silica gel layer is installed on the gasket strip. The silica gel layer is located on the surface of the gasket strip away from the elastic sleeve, and the cutting slot passes through the silica gel layer.

[0008] 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.

[0009] Preferably, the raised strip includes a rod-shaped strip and a ring-shaped strip, and the ring-shaped strips are evenly distributed along the length direction of the gasket strip.

[0010] Preferably, the surfaces of the ring-shaped strip, the rod-shaped strip, and the silicone layer are roughened.

[0011] Preferably, an air cavity is formed inside the ring-shaped strip, and the air cavity is inflated after being punctured by a syringe needle.

[0012] The beneficial effects of the present invention are as follows: 1. For the portable hemostatic device of the present invention, by providing the gasket strip and the guiding groove, the staff can directly insert a scalpel into the guiding groove and cut the elastic woven sleeve and the elastic contraction ring along the guiding groove, so as to quickly, conveniently and safely remove the hemostatic device. Moreover, the inclined guiding groove relatively increases the thickness of the gasket strip, preventing the scalpel from cutting through the gasket strip and scratching the patient's limb. At the same time, the gasket strip and the elastic woven sleeve are an integral whole, avoiding the problems that the gasket strip, as an independent accessory, is easy to be lost or dropped, and there is no need for the staff to additionally install the gasket strip when removing the hemostatic device, which is convenient and fast.

[0013] 2. For the portable hemostatic device of the present invention, by providing the raised strip, the ring-shaped strip and the air cavity, the effect of driving away and stopping bleeding of the blood in the limb soft tissue by the elastic woven sleeve is increased, preventing the thickness of the gasket strip itself from forming a gap between the elastic woven sleeve and the skin and affecting the hemostatic effect. At the same time, the expansion of the ring-shaped strip and the air cavity will improve the effect of driving away and stopping bleeding of the limb, and will also increase the friction between the elastic woven sleeve and the limb, preventing the elastic woven sleeve from creeping and shrinking due to the change in the thickness of the limb and the movement of the limb.

Specific embodiments

[0016] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] As Figures 1 to 6 shown, a portable blood expulsion and hemostasis device of the present invention includes an elastic contraction ring 1, an elastic woven sleeve 3 and a ribbon 2. The elastic woven sleeve 3 and the ribbon 2 are wound around the elastic contraction ring 1 in a rolling manner starting from the end. A handle 4 is installed at the end of the ribbon 2, and the end of the elastic woven sleeve 3 is tied by a tie strap 5; The elastic woven sleeve 3 and the elastic contraction ring 1 are sleeved on the limb of the patient to be hemostatic; It further includes a gasket strip 6. The gasket strip 6 is attached to the surface of the elastic woven sleeve 3. The gasket strip 6 is located between the elastic woven sleeve 3 and the surface of the limb, and at least two gasket strips 6 are evenly distributed along the circumferential direction of the elastic contraction ring 1; The gasket strip 6 is made of an elastic plastic material, and the gasket strip 6 and the elastic woven sleeve 3 are wound around the elastic contraction ring 1 together; During use, the end of the limb to be hemostatic is passed through the hole of the elastic contraction ring 1. Then, the staff first holds the patient's limb, and then pulls the ribbon 2 through the handle 4 to make the elastic contraction ring 1 roll along the limb, driving the elastic woven sleeve 3 to cover the limb. After that, when the elastic contraction ring 1 reaches the designated position on the patient's limb, the ribbon 2 is cut, and then the elastic woven sleeve 3 at the designated position is cut off to expose the surgical incision on the limb; At the same time, when the elastic woven sleeve 3 covers the limb, the gasket strip 6 attached to the elastic woven sleeve 3 will be unwound from the elastic contraction ring 1 along with the covering of the elastic woven sleeve 3 and pressed on the skin 7 on the surface of the limb; During the process of the elastic contraction ring 1 rolling along the limb, the mechanical pressure of the elastic contraction ring 1 will expel blood. Then, in cooperation with the pressure of the elastic woven sleeve 3, the arterial blood flow of the limb is blocked to achieve the effect of blood expulsion and hemostasis; At the same time, after the operation is completed, due to the presence of the gasket strip 6 between the elastic woven sleeve 3 and the skin 7, the staff can directly use a scalpel or other sharp cutting tools to slide and cut along the gasket strip 6 to quickly and conveniently cut off the elastic woven sleeve 3 and the elastic contraction ring 1 and remove the blood expulsion and hemostasis device; Meanwhile, the gasket strip 6 is used to support the cut scalpel, facilitating the staff to directly use the scalpel to cut the elastic woven sleeve 3 and the elastic contraction ring 1, facilitating the removal of the hemostatic device and improving the removal speed; Meanwhile, when the scalpel cuts the elastic contraction ring 1 and the elastic woven sleeve 3, the tip of the scalpel will slide along the surface of the gasket strip 6, so as to utilize the gasket strip 6 to guide and position the blade of the scalpel, avoiding excessive downward pressure or deviation during sliding of the scalpel, resulting in the blade scratching the limb and causing additional harm and pain to the patient; Meanwhile, since the gasket strip 6 is attached and installed on the elastic woven sleeve 3 and is pressed by the elastic woven sleeve 3 on the surface of the skin 7, the gasket strip 6 and the elastic woven sleeve 3 form a whole, enabling the staff to directly use the scalpel to cut along the surface of the gasket strip 6 and remove the hemostatic device without the need to additionally use other tools or removal accessories carried with the hemostatic device, such as plastic plates, thus avoiding the situation of loss and omission of plastic accessories. At the same time, since the gasket strip 6 is pressed and fixed by the elastic woven sleeve 3, it can also prevent the gasket strip 6 from shifting during the cutting of the elastic woven sleeve 3 and the elastic contraction ring 1 by the blade, resulting in scratching of the limb; A guiding groove 61 is formed on the surface of the gasket strip 6. The opening of the guiding groove 61 faces the elastic woven sleeve 3. The cross-section of the guiding groove 61 is triangular, and the guiding groove 61 is inclined relative to the surface of the gasket strip 6; Insert the blade at the tip of the scalpel into the guiding groove 61. When the scalpel slides along the surface of the gasket strip 6 and cuts the elastic woven sleeve 3 and the elastic contraction ring 1, it will be accurately guided and limited, avoiding the hand of the staff holding the scalpel from shaking or the limb of the patient from shaking during the removal of the hemostatic device, resulting in the blade of the scalpel slipping off the gasket strip 6 and the blade scratching the patient's limb; Meanwhile, since the guiding groove 61 is inclined, after the blade at the tip of the scalpel is inserted into the guiding groove 61, the scalpel will be inclined relative to the surface of the gasket strip 6, increasing the thickness of the gasket strip 6 in the direction of the tip of the scalpel pointing to the patient's limb, increasing the difficulty of the blade of the scalpel cutting through the gasket strip 6, and avoiding the tip of the scalpel vertically contacting the gasket strip 6, resulting in the scalpel cutting through the gasket strip 6 and scratching the patient's limb; Meanwhile, through the inclined guiding groove 61, the inclined thickness on the gasket strip 6 is used to replace the thickness in the vertical direction, making the function of the gasket strip 6 with a smaller thickness when the scalpel is inclined equivalent to that of the gasket strip 6 with a larger thickness when the scalpel is vertical, that is, the gasket strip 6 with a smaller thickness can be used to replace the gasket strip 6 with a larger thickness, thus facilitating the attachment and installation of the gasket strip 6 on the elastic woven sleeve 3 and winding it around the elastic contraction ring 1 together with the elastic woven sleeve 3, avoiding the large thickness of the gasket strip 6 from affecting the winding of the elastic woven sleeve 3 on the elastic contraction ring 1.

[0018] As an implementation manner of the present invention, a slit groove 62 is provided on the surface of the gasket strip 6 away from the elastic woven sleeve 3, and the slit groove 62 is in an expanded state when the gasket strip 6 is wound around the elastic contraction ring 1; Since the slit groove 62 is provided on the gasket strip 6, when the gasket strip 6 is wound around the elastic contraction ring 1 together with the elastic woven sleeve 3, the slit groove 62 on the gasket strip 6 will change from a state of being closely attached to each other to an expanded state, thereby reducing the magnitude of the elastic force required during the winding process of the gasket strip 6 and avoiding excessive elastic force for the gasket strip 6 to return to its original state after winding, which may cause the gasket strip 6 at the end of the elastic woven sleeve 3 to separate and affect the normal use of the hemostatic device; At the same time, by providing the slit groove 62 on the gasket strip 6, the thickness of the gasket strip 6 in the direction perpendicular to the gasket strip 6 at the slit groove 62 is relatively small. Therefore, after the hemostatic device is covered on the limb, the staff can cut the gasket strip 6 at the slit with a scalpel, so as to facilitate cutting off a part of the elastic woven sleeve 3 to expose the surgical incision.

[0019] As an implementation manner of the present invention, a silica gel layer 63 is installed on the gasket strip 6, the silica gel layer 63 is located on the surface of the gasket strip 6 away from the elastic woven sleeve 3, and the slit groove 62 passes through the silica gel layer 63; Since the hardness of the gasket strip 6 is relatively large compared to the skin on the limb, and the gasket strip 6 unfolds from the state of being wound around the elastic contraction ring 1 and adheres to the surface of the limb again, the slit grooves 62 on the gasket strip 6 will gradually contract 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 groove 62 and be squeezed by the slit groove 62. Therefore, the silica gel layer 63 is provided on the gasket strip 6 to isolate the gasket strip 6 from the skin 7 on the surface of the limb by using the silica gel layer 63, and to avoid the gap of the slit groove 62 squeezing the embedded skin 7 when the slit groove 62 adheres to the surface of the skin 7.

[0020] As an implementation manner of the present invention, a raised strip 64 is installed on the silica gel 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 silica gel layer 63; Due to the influence of the thickness that the gasket strip 6 and the silica gel layer 63 must have to achieve the breeding effect, when the elastic woven sleeve 3 presses the gasket strip 6 onto the skin 7 surface of the limb, gaps will appear at the positions on both sides of the gasket strip 6 in the width direction near the elastic woven sleeve 3, forming a void area 8, so that the squeezing force of the area where the void area 8 is located on the elastic woven sleeve 3 on the limb is relatively small, thereby affecting the effect of driving away the blood in the soft tissue of the limb and causing the hemostatic effect of the hemostatic device to be affected; 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 to 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 at the corresponding position of the gap area 8 on the limb, thereby ensuring the hemostatic effect of the hemostatic device.

[0021] As an embodiment of the present invention, the raised strip 64 includes a rod-shaped strip and an annular strip 65, and the annular strip 65 is evenly distributed along the length direction of the gasket strip 6; After the elastic sleeve 3 covers 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 contraction 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.

[0022] 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; By setting the raised strip 64 and the silicone layer 63, after the gasket strip 6 is pressed against 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 creeping and shrinking 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.

[0023] As an embodiment of the present invention, an air cavity 651 is provided inside the annular strip 65, and the air cavity 651 is inflated after being pierced by a syringe needle; When the hemostatic effect of the limb is not good or the patient's limb movements are relatively frequent, the staff directly inserts 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; 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, affecting the normal use of the hemostatic device.

[0024] The specific workflow is as follows: During use, the end of the limb to be hemostatic is passed through the hole of the elastic contraction ring 1. After that, the staff first holds the patient's limb, and then pulls the color ribbon 2 through the handle 4, so that the elastic contraction ring 1 rolls along the limb, driving the elastic sleeve 3 to cover the limb. After that, after the elastic contraction ring 1 reaches the designated position on the patient's limb, the color ribbon 2 is cut off. Then, the elastic sleeve 3 at the designated position is cut off to expose the surgical incision on the limb; At the same time, when the elastic sleeve 3 covers the limb, the gasket strip 6 attached and installed on the elastic sleeve 3 will be unwound from the elastic contraction ring 1 along with the covering of the elastic sleeve 3 and pressed on the skin 7 on the surface of the limb; After the operation is completed, due to the presence of the gasket strip 6 between the elastic sleeve 3 and the skin 7, the staff can directly use a scalpel or other sharp cutting equipment to slide and cut along the gasket strip 6, quickly and conveniently cutting off the elastic sleeve 3 and the elastic contraction ring 1 to remove the hemostatic device; The tip of the scalpel will slide along the surface of the gasket strip 6, using the gasket strip 6 to guide and position the blade of the scalpel; Insert the blade of the tip of the scalpel into the guiding groove 61, so that when the scalpel slides along the surface of the gasket strip 6 and cuts the elastic sleeve 3 and the elastic contraction ring 1, it will be accurately guided and limited; Since the guiding groove 61 is inclined, after the blade of the tip of the scalpel is inserted into the guiding groove 61, the scalpel will be inclined relative to the surface of the gasket strip 6, making the thickness of the gasket strip 6 in the direction of the patient's limb at the tip of the scalpel increase, increasing the difficulty for the blade of the scalpel to cut through the gasket strip 6; At the same time, through the inclined guiding groove 61, using the inclined thickness on the gasket strip 6 to replace the thickness in the vertical direction, making the thickness of the gasket strip 6 with a smaller thickness when the scalpel is inclined equivalent to the thickness of the gasket strip 6 with a larger thickness when the scalpel is perpendicular, that is, the gasket strip 6 with a smaller thickness can be used to replace the gasket strip 6 with a larger thickness, so as to facilitate the attachment and installation of the gasket strip 6 on the elastic sleeve 3 and wind it around the elastic contraction ring 1 together with the elastic sleeve 3; Since the slotted groove 62 is provided on the gasket strip 6, when the gasket strip 6 is wound around the elastic contraction ring 1 together with the elastic sleeve 3, the slotted groove 62 on the gasket strip 6 will change from a state of being closely attached to an expanded state, thereby reducing the magnitude of the elastic force required during the winding process of the gasket strip 6; At the same time, by providing the slotted groove 62 on the gasket strip 6, the thickness of the gasket strip 6 in the direction perpendicular to the gasket strip 6 at the slotted groove 62 is relatively small. Therefore, after the hemostatic device covers the limb, the staff can cut the gasket strip 6 at the slotted area with a scalpel, facilitating the cutting off of the local elastic sleeve 3 to expose the surgical incision; A silica gel layer 63 is provided on the gasket strip 6. The silica gel layer 63 is used to isolate the gasket strip 6 from the skin 7 on the surface of the limb, so as to prevent the gap of the cutting slot 62 from squeezing and embedding the skin 7 when the gasket strip 6 is attached to the surface of the skin 7. Since the raised strip 64 is installed on the silica gel layer 63 and the length of the raised strip 64 is greater than the width of the silica gel layer 63, when the elastic woven sleeve 3 presses the gasket strip 6 against the surface of the limb, the raised strip 64 on the silica gel layer 63 will pass through the void area 8 to drive away and block the blood in the soft tissue at the corresponding position of the void area 8 on the limb. After the elastic woven sleeve 3 covers the limb, by arranging the annular strip 65 to press and block the soft tissue on the limb multiple times to prevent blood flow in the soft tissue, so that when there is still blood in the soft tissue in the area covered by the elastic woven sleeve 3 on the limb that has not been completely driven away or the elastic contraction ring 1 has a poor effect on driving away and blocking the blood in the limb, a good hemostatic effect on the limb can still be ensured. By arranging the raised strip 64 and the silica gel layer 63, after the gasket strip 6 is pressed by the elastic woven sleeve 3 onto the surface of the skin 7 on the limb, 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, avoiding the elastic woven sleeve 3 from creeping and wrinkling on the limb of the patient when the thickness change of the limb covered by the elastic woven sleeve 3 on the patient is relatively large or the movement of the patient's limb is relatively frequent. When the blood driving and hemostatic effect on the limb is poor or the movement of the patient's limb is relatively frequent, the staff directly inserts the needle of the syringe into the air cavity 651, and then injects air into the air cavity 651 to expand the annular strip 65 and increase the pressure of the annular strip 65 on the limb. At the same time, after inflating the air cavity 651 and expanding the annular strip 65, the acting force of the annular strip 65 on the limb also increases, further increasing the friction between the annular strip 65 and the limb, and avoiding the elastic woven sleeve 3 from sliding or wrinkling on the limb.
