DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] The embodiment of the present invention provides an automatic pressurizing hemostatic patch, comprising a patch plate 1 and a pressing plate 2;

[0037] See attached Figures 1 to 4As shown, the patch 1 can be covered on the back of the patient's hand, and a through hole 11 is provided on the patch 1. A ring 3 with an annular structure is provided around the through hole 11 on the patch 1, and the ring 3 is fixedly connected to the patch 1. The pressing plate 2 is located above the patch 1. The pressing plate 2 is designed in a disc shape, and the outer diameter of the pressing plate 2 is larger than the outer diameter of the ring 3. A spring 4 is provided between the pressing plate 2 and the ring 3. The two ends of the spring 4 are respectively fixedly connected to the bottom end of the pressing plate 2 and the top end of the ring 3, and the pressing plate 2 can be pulled closer to the ring 3 under the tension of the spring 4. The first strap 5 and the second strap 6 are respectively provided on both sides of the patch 1;

[0038] In clinic, some tumor patients have coagulation disorders, and need to press longer than normal people after the needle is removed. Therefore, after the intravenous injection of the hand of the tumor patient and the patient with coagulation disorder is completed, the medical post-needle patch is used to cover the infusion needle hole on the back of the hand of the tumor patient and the patient with coagulation disorder, and then the hemostatic patch designed by the present invention is moved to the back of the patient's hand, and the pressing plate 2 is pressed so that the bottom of the pressing plate 2 squeezes the post-needle patch through the through hole 11 on the patch plate 1, and then the first binding band 5 and the second binding band 6 are respectively taken from the tumor The two sides of the tumor patient's hand are covered and pulled to the palm to connect, so that the entire hemostatic patch is fixed on the back of the patient's hand. At this time, under the pulling force of the spring 4, a downward pulling force is applied to the pressing plate 2, so that the bottom end of the pressing plate 2 can press from the upper surface of the post-needle patch, and the downward pressure of the pressing plate 2 is concentrated on the through hole 11 of the patch plate 1, so as to replace the medical staff or the patient's family members to press the post-needle patch covering the back of the tumor patient's hand, and the infusion needle hole is pressurized to promote blood coagulation;

[0039] Since the entire hemostatic patch is wearable and connected to the back of the hand of the tumor patient, the pressing operation can be maintained for a long time, so that the patch can be in a long-term pressure state after covering the infusion needle hole on the back of the tumor patient's hand, thereby playing a hemostatic effect on the infusion needle hole, and after the hemostasis of the infusion needle hole on the back of the tumor patient's hand is completed, the first strap 5 and the second strap 6 can be untied immediately to remove the entire hemostatic patch;

[0040] In clinical applications, it can replace medical staff or patients' families in pressing the post-needle patch, which can effectively avoid restrictions on the actions of medical staff, patients' families and patients themselves due to manual pressing of the post-needle patch on the infusion needle hole, allowing patients to urinate and move freely at any time. At the same time, it also provides long-term pressing hemostasis function for patients with coagulation dysfunction and after deep vein (CVC / PICC / infusion port) tube and needle removal.

[0041] In a further preferred embodiment, refer to the attached Figure 5 and 6As shown, the outer wall of the snap ring 3 is sleeved with an adjusting piece 31, and a through groove 32 whose outer diameter matches the outer diameter of the snap ring 3 is provided at the center of the adjusting piece 31. The adjusting piece 31 is located between the pressing plate 2 and the sticking plate 1, and the adjusting piece 31 can rotate on the outer wall of the snap ring 3;

[0042] The outer wall of the snap ring 3 is provided with an external thread 33, and the inner wall of the through groove 32 of the adjusting member 31 is provided with an internal thread 34 matching the external thread 33 on the snap ring 3. When the outer wall of the snap ring 3 rotates, the adjusting member 31 can be threadedly matched with the snap ring 3.

[0043] When in use, the adjusting member 31 needs to be adjusted to the lowest height on the clamp ring 3 to ensure that the pressing plate 2 can be at the lowest horizontal position to press the post-needle patch; after the pressing plate 2 presses the post-needle patch on the infusion needle hole on the back of the hand of the tumor patient for a period of time, the adjusting member 31 can be slightly rotated to allow the adjusting member 31 to rise a certain distance along the spiral track of the external thread 33 on the outer wall of the clamp ring 3 under the action of the internal thread 34, so that the adjusting member 31 applies an upward thrust to the bottom edge of the pressing plate 2 and allows the pressing plate 2 to rise a certain distance, thereby reducing the pressing force of the pressing plate 2 on the post-needle patch;

[0044] In actual application, the sleeve height of the adjusting member 31 on the clamping ring 3 can also be adjusted according to the state of the venous blood vessels on the back of the patient's hand, so that the adjusting member 31 can drive the pressure plate 2 to adjust its height, thereby adjusting the pressure of the bottom of the pressure plate 2 on the post-needle patch to match the different states of the venous blood vessels on the back of the hand of each tumor patient.

[0045] In a further preferred embodiment, refer to the attached Figures 5 to 8 As shown, the outer side of the adjusting member 31 is circular, and a plurality of teeth 35 are arranged equidistantly around the circular outer side of the adjusting member 31, so that the adjusting member 31 as a whole forms a toothed ring structure;

[0046] A driving mechanism 36 is provided on one side of the adjusting member 31 on the plate 1. The driving mechanism 36 includes a gear 37, a chuck 38 and a stop bar 39 that match the teeth 35 on the outer side of the adjusting member 31. The gear 37 is rotatably provided on the plate 1. The number of teeth 35 on the gear 37 is less than the number of teeth 35 on the outer side of the adjusting member 31, and the gear 37 is meshed with the teeth 35 on the outer side of the adjusting member 31. The chuck 38 is fixedly provided at the top of the gear 37. The stop bar 39 is provided on the outer side of the chuck 38 in a half-wrapped state after being bent as a whole, and the stop bar 39 is fixedly connected to the plate 1.

[0047] A spirally wound elastic sheet steel bar 381 is provided at the top of the chuck 38, the outer end of the elastic sheet steel bar 381 is fixedly connected to the stop bar 39, a hand-tightening rod 382 is provided at the top of the chuck 38, the top of the hand-tightening rod 382 is fixedly connected to the center of the chuck 38, and the hand-tightening rod 382 is fixedly connected to the inner end of the elastic sheet steel bar 381, a baffle 391 is fixedly provided above the stop bar 39 to shield the elastic sheet steel bar 381, and the thickness of the gear 37 is greater than the thickness of the entire adjusting member 31;

[0048] The long-term pulling force exerted by the spring 4 on the pressing plate 2 will cause the pressing plate 2 to continuously press the post-needle patch on the infusion needle hole on the back of the tumor patient's hand. During this process, if the medical staff or the patient's family members fail to remove the entire hemostatic patch in time after the infusion needle hole on the back of the tumor patient's hand stops bleeding, the long-term squeezing of the infusion needle hole on the back of the tumor patient's hand by the pressing plate 2 will cause compression injuries to the infusion needle hole and surrounding skin tissues.

[0049] In order to avoid such a situation, the present invention is designed with a driving mechanism 36. When in use, the hand-tightening rod 382 can be rotated to drive the inner end of the elastic sheet steel strip 381 to be rolled up around the hand-tightening rod 382. Since the outer end of the elastic sheet steel strip 381 is fixedly connected to the retaining bar 39, the entire spirally rolled elastic sheet steel strip 381 will gradually form a tightly rolled-up state; with the rotation of the hand-tightening rod 382, ​​the corresponding chuck 38 and gear 37 will also rotate synchronously, and the gear 37 will drive the meshing toothed ring-shaped adjusting member 31 to rotate synchronously, and make the adjusting member 31 descend to the lowest height on the retaining ring 3, so as to ensure that the pressing plate 2 presses the needle back sticker at the lowest height state, and since the thickness of the gear 37 is greater than the thickness of the adjusting member 31 as a whole, the adjusting member 31 can be synchronously lifted and lowered in a meshing state on the gear 37 when it is lifted and lowered;

[0050] After completing the manipulation of the hand-tightening rod 382, ​​the hand-tightening rod 382 can be released immediately. At this time, since the hand-tightening rod 382 stops pulling the inner end of the elastic sheet steel bar 381, the elastic sheet steel bar 381 tightly wound in a spiral shape will gradually loosen under the action of its own elastic force and drive the hand-tightening rod 382, ​​the chuck 38 and the gear 37 to rotate in the opposite direction, so that the gear 37 drives the toothed ring-shaped adjusting member 31 in a meshing state to synchronously reverse. In the meantime, the baffle plate 391 above the baffle bar 39 can cooperate with the chuck 38 to block the upper and lower sides of the elastic sheet steel bar 381 to prevent the elastic sheet steel bar 381 in the wound state from twisting and deforming upward when released;

[0051] As the adjusting member 31 is reversed, the internal thread 34 on the inner side wall of the through groove 32 on the adjusting member 31 gradually rises along the thread track of the external thread 33 on the outer side wall of the clamp 3, thereby slowly pushing up the pressing plate 2, so that the pressing plate 2 gradually reduces the pressure applied to the needle back sticker;

[0052] To this end, the number of teeth 35 on the outer side of the adjusting member 31 and the number of teeth 35 on the gear 37 can be set in combination with the meshing transmission ratio of the large gear 37 and the small gear 37. For example, if the number of teeth 35 on the outer side of the adjusting member 31 is 100 and the number of teeth 35 on the gear 37 is 20, when the gear 37 rotates 5 circles, the adjusting member 31 is driven to rotate 1 circle. Therefore, the transmission ratio can be used to drive the adjusting member 31 to rise slowly on the clamp ring 3 through the reverse rotation of the gear 37, and drive the pressing plate 2 to rise slowly, so that the pressing plate 2 gradually reduces the pressing force on the post-needle patch, so as to simulate the clinical operation, when pressing the infusion needle hole on the back of the hand of the tumor patient, the pressing force needs to be gradually reduced to stop bleeding, and at the same time, avoid the infusion needle hole on the back of the patient's hand and the surrounding skin tissue from being squeezed due to long-term and strong pressing of the post-needle patch.

[0053] In clinical applications, since the elastic sheet steel strip 381 tightly wound in a spiral shape has the largest torque, the elastic sheet steel strip 381 is initially loosened with a large force, which will drive the hand-tightening rod 382 and the gear 37 to accelerate the reverse rotation, and cause the adjusting member 31 to be unable to lift the pressure plate 2 upward at a slow rising speed, resulting in the pressure plate 2 being unable to effectively press the post-needle patch during initial use. Therefore, in order to prevent such a situation from occurring, when in use, after rotating the hand-tightening rod 382 to tighten the elastic sheet steel strip 381, the hand-tightening rod 382 can be held in a fixed state for a period of time, allowing the pressure plate 2 to press the post-needle patch for a short period of time to allow the infusion needle hole on the back of the patient's hand to be pressed with the maximum force to stop bleeding, and then gradually reduce the pressing force to ensure that the gear 37 will not cause the pressure plate 2 to reduce the pressing force on the post-needle patch too early due to reversal, resulting in the inability to effectively stop bleeding.

[0054] The present invention does not require a power supply device during use, can provide portability and lightness in clinical applications, and can be adapted to a variety of medical environments.

[0055] In a further preferred embodiment, refer to the attached Fig. 9 As shown, the outer side of the pressing plate 2 is provided with an extension edge 21, and the extension edge 21 of the outer side of the pressing plate 2 can cover the adjusting member 31, and a slide groove 22 with an annular track is provided around the bottom end of the extension edge 21 and the top end of the adjusting member 31, and the positions of the slide groove 22 at the bottom end of the extension edge 21 and the slide groove 22 at the top end of the adjusting member 31 are symmetrical to each other, and a plurality of balls 23 are provided between the slide groove 22 at the bottom end of the extension edge 21 and the slide groove 22 at the top end of the adjusting member 31;

[0056] When the adjusting member 31 is lifted up on the retaining ring 3, the top end of the adjusting member 31 will be in close contact with the bottom end of the pressing plate 2, and the close friction between the components will easily cause the pressing plate 2 to shake, thereby affecting the pressing stability of the needle back patch. Therefore, an extension edge 21 is provided on the outer side of the pressing plate 2, and a slide groove 22 with an annular track and a plurality of balls 23 are provided around the bottom end of the extension edge 21 and the top end of the adjusting member 31. When the adjusting member 31 is gradually lifted up in a rotating state, the plurality of balls 23 between the adjusting member 31 and the pressing plate 2 will immediately move in the slide groove 22 between the two, so as to avoid direct contact between the adjusting member 31 and the pressing plate 2, and utilize the rolling characteristics of the balls 23 to allow the adjusting member 31 to be in a smooth rotation state when pushing the pressing plate 2 upward, so as to allow the pressing plate 2 to maintain a stable state during the slow rising process, and to ensure the stable pressure state of the needle back patch.

[0057] In a further preferred embodiment, refer to the attached Fig. 9 As shown, a pad 24 is provided at the center of the bottom end of the pressing plate 2, the top end of the pad 24 is fixedly connected to the pressing plate 2, and both the pressing plate 2 and the pad 24 are made of transparent material;

[0058] In clinical applications, the covering status of the post-needle patch on the infusion needle hole on the back of the tumor patient's hand can be observed through the transparent pressing plate 2 and the pad 24, so as to determine whether the post-needle patch covers the infusion needle hole in the correct position. Secondly, the pad 24 at the bottom end of the pressing plate 2 can increase the extended height of the bottom end of the pressing plate 2, so that the pad 24 can effectively press the post-needle patch.

[0059] In a further preferred embodiment, refer to the attached Fig.10 As shown, an extension tube 7 is arranged in the middle of the spring 4, and the two ends of the extension tube 7 are fixedly connected to the top of the clamp ring 3 and the bottom of the pressure plate 2. The wall of the extension tube 7 is provided with multiple layers of folds so that the extension tube 7 as a whole is similar to a bellows structure;

[0060] The extension tube 7 is provided to form a connection between the pressing plate 2 and the clamping ring 3, and to cover the gap between the pressing plate 2 and the clamping ring 3, so that during the use of the entire hemostatic patch, no foreign objects will come into contact with the post-needle patch on the back of the patient's hand through the gap between the two, and to prevent the patient or others from touching the post-needle patch and the skin around the infusion needle hole on the back of the patient's hand, causing bacteria to come into contact with the post-needle patch and the skin around the infusion needle hole on the back of the patient's hand; secondly, the extension tube 7 is set to be similar to a bellows structure, so that when the pressing plate 2 is lowered, the extension tube 7 will shrink immediately due to being squeezed, thereby reducing the blocking distance between the pressing plate 2 and the clamping ring 3 by the extension tube 7, so that the pad 24 at the bottom end of the pressing plate 2 can press the post-needle patch at the lowest height.

[0061] In a further preferred embodiment, refer to the attached Figure 1 and 2 As shown, the outer sides of the first strap 5 and the second strap 6 are both bifurcated, the bottom of the first strap 5 is provided with a Velcro hook surface 51, and the top of the second strap 6 is provided with a Velcro fur surface 61 that can be bonded and connected with the Velcro hook surface 51;

[0062] The thumb is an important part of the human hand for holding objects. If it is bound, it will cause inconvenience to the patient's hand movement. In addition, when the first strap 5 or the second strap 6 covers the outer side of the thumb on the back of the patient's hand, it will cause discomfort to the patient. Therefore, the outer sides of the first strap 5 and the second strap 6 are both set to be forked. When the first strap 5 or the second strap 6 corresponding to the patient's thumb is used, the forked ends can cover the thumb from both sides and then cover the palm, so that the forked part on the first strap 5 or the second strap 6 can provide a place for the patient's thumb, so that the patient's thumb is no longer bound.

[0063] When fixing the hemostatic patch, the second strap 6 can be covered on one side of the patient's hand and then pulled toward the palm, and then the first strap 5 can be covered on the second strap 6 through the other side of the patient's hand, so that the Velcro hook surface 51 on the first strap 5 and the Velcro fur surface 61 on the second strap 6 form an adhesive connection, so that the entire hemostatic patch can be worn on the patient's hand. At the same time, the first strap 5 and the second strap 6 are easily operated through the Velcro adhesive connection method.

[0064] In a further preferred embodiment, refer to the attached Fig.11 As shown, a first gasket 12 and a second gasket 13 are fixedly arranged on both sides of the bottom of the patch board 1, and the first gasket 12 and the second gasket 13 are both made of flexible silicone material, wherein the thickness of the second gasket 13 is greater than that of the first gasket 12, and the second gasket 13 is designed as a slope as a whole;

[0065] Since the back of the human hand is not a straight surface, when the patch 1 covers the back of the patient's hand, there is a certain gap between the two sides of the patch 1 and the back of the patient's hand. These gaps will reduce the contact area between the patch 1 and the back of the patient's hand, which may easily cause the patch 1 to tilt on the back of the patient's hand. Therefore, a first gasket 12 and a second gasket 13 are respectively provided on both sides of the bottom of the patch 1. When in use, the second gasket 13 needs to correspond to the outer side of the patient's hand to fill the gap between the edge of the patch 1 and the back of the patient's hand.

[0066] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
