Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to hemostatic devices for arterial blood collection after ICU surgery. Background Technology

[0002] Arterial blood sampling is an important clinical diagnostic tool. By drawing arterial blood for blood gas analysis, medical staff can help determine the patient's acid-base balance and oxygen levels. After arterial blood sampling, pressure needs to be applied to the puncture site to stop the bleeding. For critically ill patients in the ICU after surgery, whose vital signs are even worse, hemostasis after blood sampling is particularly important.

[0003] Patent CN110897670B discloses a hemostatic device for arterial blood sampling after EICU surgery. This device includes a housing, with a screw movably connected inside. A compression wheel is movably connected to the surface of the screw, and a spring rod is movably connected inside the compression wheel. A connecting cover is movably connected to the surface of the compression wheel, and a wire loop is movably connected to the surface of the connecting cover. A traction rope is movably connected to the surface of the wire loop, and a tensioning post is movably connected to the end of the traction rope away from the wire loop. Moving the spring rod moves the puncture hole. Repeated finger movements until a numb sensation is felt in the hand help medical personnel locate the puncture site. Once this sensation is found, and the two fingers are separated, further movement of the index and ring fingers prevents the differential shaft from moving due to differences in the winding angle and speed of the two traction ropes on the surface of the traction rod, thus fixing the puncture site. However, the hemostatic device for arterial blood sampling after EICU surgery can only be used at the wrist for radial artery blood sampling. In clinical use, different patients have different conditions, so the blood sampling point is also different. The hemostatic device for arterial blood sampling after EICU surgery can only be used for radial artery blood sampling, which has a large limitation.

[0004] Therefore, we propose a hemostatic device for postoperative arterial blood collection in the ICU that can be adjusted according to different blood collection sites. Summary of the Invention

[0005] In order to overcome the limitation of existing hemostatic devices for arterial blood sampling after EICU surgery which can only be used for radial artery blood sampling, this invention provides a hemostatic device for arterial blood sampling after ICU surgery that can be adjusted according to different blood sampling locations.

[0006] The technical implementation of the present invention is as follows: a hemostatic device for arterial blood collection after ICU surgery, comprising an adhesive block, a restraint band connected to the adhesive block, a rotating block rotatably connected to the adhesive block, a fixed cylinder fixedly connected to the rotating block, and symmetrically arranged guide rails fixedly connected to the fixed cylinder. A sliding block is slidably connected to the guide rails, a rotating rod is rotatably connected to the sliding block, a first clamping plate is fixedly connected between the symmetrically arranged rotating rods, a sliding frame is slidably connected to the first clamping plate, a second clamping plate is fixedly connected to the sliding frame, and symmetrically arranged first springs are connected between the sliding frame and the first clamping plate. The adhesive block is provided with a tension adjustment mechanism for adjusting the tightness of the restraint band, and the fixed cylinder is provided with a pressure adjustment mechanism for adjusting the pressure hemostatic force.

[0007] Optionally, both the first and second clamps are semi-circular and fit together to form a hollow spherical structure for placing hemostatic cotton.

[0008] Optionally, the tension adjustment mechanism includes a storage tube, which is fixedly connected to the bonding block. The storage tube is rotatably connected to a take-up roller, and the end of the restraint strap is wound around the take-up roller. The storage tube is rotatably connected to a positioning plate, and a first torsion spring is symmetrically arranged between the positioning plate and the storage tube.

[0009] Optionally, the side of the locking plate closest to the restraint strap has a serrated structure to hold the restraint strap in place.

[0010] Optionally, the pressure adjustment mechanism includes a threaded rod, which is rotatably connected to the fixed cylinder. The threaded rod is threadedly connected to a nut, and the nut is fixedly connected to a first connecting rod arranged in a stacked manner. The first connecting rod passes through the fixed cylinder and the guide rail and is connected to an adjacent sliding block. The threaded rod is fixedly connected to a handle.

[0011] Optionally, it also includes a fixing mechanism for fixing the rotating block. The fixing mechanism is disposed in the fixing cylinder and includes a spring telescopic rod. The spring telescopic rod is fixedly connected to the fixing cylinder. The telescopic end of the spring telescopic rod is fixedly connected to a fixing rod. The fixing rod is fixedly connected to a pressing plate. A clamping plate is fixedly connected to the side of the rotating block near the pressing plate. A sliding rod is slidably connected to the side of the fitting block near the pressing plate. A second spring is connected between the sliding rod and the fitting block. Limiting blocks are fixedly connected to the sides of the symmetrically arranged sliding rods that are close to each other. The limiting blocks are sleeved on the clamping plate.

[0012] Optionally, the extrusion plate has symmetrically arranged inclined surfaces, and the extrusion plate and the limiting block are extruded together.

[0013] Optionally, it also includes a reversing mechanism for reversing the direction of the hemostatic cotton. The reversing mechanism is disposed on the rotating rod and includes symmetrically arranged one-way gears. The symmetrically arranged one-way gears are fixedly connected to the rotating rod. A guide rod is fixedly connected to the guide rail. A rack is slidably connected to the guide rod. The rack meshes with an adjacent one-way gear. A third spring is connected between the rack and the adjacent guide rod. A contact rod is fixedly connected to the rack. The contact rod is in pressure contact with the adhesive block.

[0014] Optionally, it also includes a stabilizing mechanism for controlling the adhesive block to remain in contact with the skin. The stabilizing mechanism is disposed on the adhesive block and includes symmetrically arranged fixing blocks. The symmetrically arranged fixing blocks are fixedly connected to the adhesive block. A stabilizing plate is rotatably connected between the symmetrically arranged fixing blocks. A second torsion spring is connected between the stabilizing plate and the adjacent fixing block.

[0015] Optionally, it also includes a reinforcement mechanism for reinforcing the fixed cylinder to prevent tilting. The reinforcement mechanism is disposed on the restraint strap and includes a connecting block. The connecting block is fixedly connected to the restraint strap. The connecting block is rotatably connected to a second connecting rod. The second connecting rod is rotatably connected to a third connecting rod. The third connecting rod is fixedly connected to the fixed cylinder.

[0016] The present invention has the following advantages: 1. The hemostatic cotton is sandwiched between the first and second clamps. The device is placed on the puncture site of the patient's arterial blood collection by the binding strap. Depending on the puncture site, the winding roller and the positioning plate can adjust the length of the binding strap, thereby adjusting the tightness. At the same time, the threaded rod and the nut can also adjust the position of the first and second clamps, thereby adjusting the position of the hemostatic cotton, so as to adjust the pressure applied to the puncture point to adapt to the pressure hemostasis at different blood collection sites.

[0017] 2. The position of the rotating block can be fixed by the cooperation of the limiting block and the clamping plate. At the same time, the rotating block can be rotated upward and opened without removing the restraint belt, so as to observe the hemostasis of the puncture point.

[0018] 3. By pressing and engaging the contact rod with the fitting block, the rack and the one-way gear can mesh. Then, after the staff opens the rotating block to observe the puncture point, the hemostatic cotton will automatically reverse, turning the clean side of the hemostatic cotton downwards to contact the puncture point and continue to stop the bleeding.

[0019] 4. The stabilizing plates on the front and back sides follow the adhesive block to fit the patient's skin, increasing the contact area with the patient's skin, improving the stability of the device's fit, and ensuring that the hemostatic cotton remains in contact with the puncture point.

[0020] 5. The connecting block is fixedly connected to the left end of the restraint strap. The connecting block and the fixing cylinder are connected together by the second connecting rod and the third connecting rod to prevent the fixing cylinder from tilting and to avoid the adhesive block from lifting up and affecting the contact between the hemostatic cotton and the puncture point.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this document are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0036] Example 1: Hemostatic devices for arterial blood collection after ICU surgery, such as... Figures 1-5 As shown, it includes an adhesive block 1, a restraint strap 101, a rotating block 2, a fixed cylinder 3, a guide rail 4, a sliding block 5, a rotating rod 6, a first clamping plate 7, a sliding frame 8, a second clamping plate 9, a first spring 10, a tension adjustment mechanism, and a pressing pressure adjustment mechanism. The restraint strap 101 is connected to the left side of the adhesive block 1. The rotating block 2 is rotatably connected to the middle of the adhesive block 1. The fixed cylinder 3 is fixedly connected to the upper side of the rotating block 2. The guide rails 4 are fixedly connected to both the left and right sides of the fixed cylinder 3. The sliding block 5 is slidably connected to the guide rail 4. The rotating rod 6 is rotatably connected to the sliding block 5. A first clamping plate 7 is fixedly connected between the two rotating rods 6 on the right. A sliding frame 8 is slidably connected to the first clamping plate 7. A second clamping plate 9 is fixedly connected to the front side of the sliding frame 8. Both the first clamping plate 7 and the second clamping plate 9 are semi-circular and fit together to form a hollow spherical structure for placing hemostatic cotton. Four first springs 10 are connected between the sliding frame 8 and the first clamping plate 7. A tension adjustment mechanism is provided on the right side of the fitting block 1. The tension adjustment mechanism can adjust the tension of the restraint belt 101. A pressure adjustment mechanism is provided on the fixed cylinder 3. The pressure adjustment mechanism can adjust the pressure hemostasis force.

[0037] When using the device, the operator pushes the second clamp 9 forward. This forward movement causes the sliding frame 8 to slide forward on the first clamp 7, deforming the first spring 10. After the second clamp 9 opens, the operator places hemostatic cotton between the second clamp 9 and the first clamp 7. Once in place, the operator releases the second clamp 9. Under the action of the first spring 10 returning to its original position, the second clamp 9 slides backward to engage with the first clamp 7 and clamp the hemostatic cotton. The operator then places the device over the patient's arterial blood sampling puncture site, thus placing the restraint strap 101 over the patient. The restraint strap varies depending on the puncture site. The staff can adjust the length of the restraint strap 101 through the tension adjustment mechanism, thereby adjusting the tightness so that the restraint strap 101 can adapt to different body parts of the patient and fix the fitting block 1 in the designated position. At this time, the hemostatic cotton between the second clamp 9 and the first clamp 7 is in contact with the blood collection puncture point. The staff can also control the sliding block 5 to slide up and down through the pressure adjustment mechanism. The sliding block 5 slides up and down, which drives the first clamp 7, the sliding frame 8 and the second clamp 9 to move up and down through the rotating rod 6, thereby adjusting the pressure of the hemostatic cotton on the patient's puncture point. In this way, the device can be adjusted according to different blood collection positions.

[0038] like Figure 1 , Figure 6 and Figure 7 As shown, the tension adjustment mechanism includes a storage cylinder 11, a take-up roller 12, a locking plate 13, and a first torsion spring 14. The storage cylinder 11 is fixedly connected to the right side of the bonding block 1. The take-up roller 12 is rotatably connected to the center of the storage cylinder 11. The tail end of the restraint strap 101 is wrapped around the take-up roller 12. The locking plate 13 is rotatably connected to the left side of the storage cylinder 11. The right end of the locking plate 13 has a serrated structure for locking the restraint strap 101. The locking plate 13 and the storage cylinder 11 are connected by a first torsion spring 14 that is symmetrically arranged front and back.

[0039] The required length of the restraint strap 101 varies depending on the blood collection point. The length of the restraint strap 101 can be adjusted using a tension adjustment mechanism, allowing it to adapt to different body parts. The specific operation is as follows: The operator pushes the left end of the locking plate 13 downwards, while the right end swings upwards. The first torsion spring 14 deforms, and the right end of the locking plate 13 no longer holds the restraint strap 101 in place. At this point, the operator can pull the restraint strap 101 out of the storage tube 11. After the restraint strap 101 has been pulled out to the appropriate length, the operator releases the locking plate 13. Under the action of the force spring 14 resetting, the locking plate 13 reverses and resets accordingly. The serrated structure at the right end of the locking plate 13 locks the restraint band 101, preventing the restraint band 101 from being pulled out further. After the device is used, the operator controls the winding roller 12 to rotate clockwise. The winding roller 12 can wind up the restraint band 101 by rotating clockwise. When the restraint band 101 is wound up, it moves in the direction of the serrated structure of the locking plate 13. Therefore, the locking plate 13 will not affect the winding of the restraint band 101. In this way, the length of the restraint band 101 can be adjusted according to different blood collection positions, thereby adjusting the tightness of the restraint band 101.

[0040] like Figure 1 and Figure 8 As shown, the pressure adjustment mechanism includes a threaded rod 15, a nut 16, a first connecting rod 17, and a handle 18. The threaded rod 15 is rotatably connected to the upper side of the fixed cylinder 3. The nut 16 is threadedly connected to the threaded rod 15. The first connecting rod 17 is fixedly connected to both the left and right sides of the nut 16. The first connecting rod 17 passes through the fixed cylinder 3 and the guide rail 4 and is connected to the adjacent sliding block 5. The handle 18 is fixedly connected to the upper part of the threaded rod 15.

[0041] Different blood collection sites have different skin shapes at the puncture points. For example, the radial artery is flat, while the brachial artery is slightly concave, and the dorsalis pedis artery is slightly convex. The pressure or pressure height required for the hemostatic cotton varies depending on the blood collection site. This can be adjusted by setting up a pressure adjustment mechanism. The specific operation is as follows: The operator drives the threaded rod 15 to rotate by the handle 18. The rotation of the threaded rod 15 drives the nut 16 to move downward. The nut 16 slides downward and the first connecting rod 17 moves downward. The downward movement of the first connecting rod 17 drives the sliding block 5 to slide and adjust its position within the guide rail 4. Then, the position of the hemostatic cotton is adjusted by the first clamp 7 and the second clamp 9 to adjust the pressure applied to the puncture point to adapt to different blood collection sites.

[0042] Example 2: Based on Example 1, such as Figure 1 and Figure 9As shown, it also includes a fixing mechanism that can fix the rotating block 2. The fixing mechanism includes a spring telescopic rod 19, a fixing rod 20, a pressing plate 21, a clamping plate 22, a sliding rod 23, a second spring 24, and a limiting block 241. The lower front part of the fixing cylinder 3 is fixedly connected to the spring telescopic rod 19, the front end of the spring telescopic rod 19 is fixedly connected to the fixing rod 20, the lower part of the fixing rod 20 is fixedly connected to the pressing plate 21, the front side of the rotating block 2 is fixedly connected to the clamping plate 22, the left and right sides of the front side of the bonding block 1 are slidably connected to the sliding rod 23, the second spring 24 is connected between the sliding rod 23 and the bonding block 1, the inner end of the sliding rod 23 is fixedly connected to the limiting block 241, the limiting block 241 is sleeved on the clamping plate 22, the rear sides of the left and right sides of the pressing plate 21 are inclined, the pressing plate 21 moves backward to press the limiting block 241 and slide away from the clamping plate 22.

[0043] During the hemostasis process, staff or patients can observe the hemostasis status. After hemostasis, the device can be removed. A fixing mechanism secures the rotating block 2, and also allows the rotating block 2 to be opened even when the restraint strap 101 is not removed, facilitating observation of the hemostasis at the puncture point. The specific operation is as follows: The staff pushes the fixing rod 20 backward, causing the spring telescopic rod 19 to shorten. Simultaneously, the fixing rod 20 moves backward, driving the compression plate 21 backward. The compression plate 21 then compresses the left and right limiting blocks 241, causing them to move in opposite directions. The sliding rods 23 on both sides slide in opposite directions, causing the second spring 24 to deform. After the limiting blocks 241 slide in opposite directions, they no longer lock the clamping plate 22. At this point... The staff can then push the fixed cylinder 3 to flip backward. The upward rotation of the fixed cylinder 3 causes the fixed rod 20 and the squeezing plate 21 to rotate backward and disengage from the limiting block 241 via the spring telescopic rod 19. Under the action of the second spring 24 resetting, the sliding rod 23 drives the limiting block 241 to move and reset in opposite directions. When the fixed cylinder 3 flips backward, it also causes the rotating block 2 to rotate backward and open, so as to observe the hemostasis of the puncture point. After the hemostasis is completed, the staff can directly remove the device. If there is bleeding, the staff controls the rotating block 2 to rotate downward and reset, and then re-fixes the clamping plate 22 through the limiting block 241, thereby fixing the position of the rotating block 2. In this way, the hemostasis of the puncture point can be observed without removing the device.

[0044] like Figure 10 and Figure 11As shown, it also includes a reversing mechanism that can reverse the direction of the hemostatic cotton. The reversing mechanism includes a one-way gear 25, a guide rod 26, a rack 27, a third spring 28, and a contact rod 29. The one-way gear 25 is fixedly connected to the rotating rod 6. The guide rod 26 is fixedly connected to the upper rear part of the guide rail 4. The rack 27 is slidably connected to the guide rod 26. The rack 27 meshes with the adjacent one-way gear 25. The third spring 28 is connected between the rack 27 and the adjacent guide rod 26. The contact rod 29 is fixedly connected to the lower end of the rack 27. The contact rod 29 is in pressure contact with the adhesive block 1.

[0045] After the rotating block 2 rotates upward and opens, the hemostatic cotton will separate from the puncture point. By setting a reversing mechanism, the first clamp 7 and the second clamp 9 can be flipped and reversed, so that the clean side of the hemostatic cotton rotates downward and contacts the puncture point to continue hemostasis. The specific operation is as follows: In the initial state, the contact rod 29 is squeezed by the fitting block 1, and the third spring 28 is in a deformed state. When the rotating block 2 and the fixed cylinder 3 rotate upward, the guide rail 4 will also drive the guide rod 26 to rotate upward, so that the contact rod 29 is no longer squeezed by the fitting block 1. Under the action of the third spring 28 resetting, the rack 27 slides forward. The forward sliding of the rack 27 drives the one-way gear 25 to rotate, and the rotation of the one-way gear 25 drives... Rotating rod 6 rotates, causing the first clamping plate 7 and the second clamping plate 9 to flip and change direction, thus rotating the clean side of the hemostatic cotton downwards. When rotating block 2 drives the fixed cylinder 3 to rotate downwards and close, guide rail 4 will also drive guide rod 26 to rotate downwards, and contact rod 29 will be squeezed backwards by contact block 1 again, thus driving rack 27 to slide backwards. The third spring 28 deforms, and rack 27 slides backwards, driving one-way gear 25 to reverse. At this time, one-way gear 25 will not drive rotating rod 6 to reverse. In this way, the hemostatic cotton can be automatically reversed after the staff opens rotating block 2 to observe the puncture point, rotating the clean side of the hemostatic cotton downwards to contact the puncture point and continue hemostasis.

[0046] like Figure 1 and Figure 12 As shown, it also includes a stabilizing mechanism, which can control the adhesive block 1 to remain in contact with the skin. The stabilizing mechanism includes a fixing block 30, a stabilizing plate 31, and a second torsion spring 311. The adhesive block 1 is fixedly connected to the front and rear sides with symmetrical fixing blocks 30. The stabilizing plate 31 is rotatably connected between the two symmetrical fixing blocks 30. The second torsion spring 311 is connected between the stabilizing plate 31 and the adjacent fixing block 30.

[0047] By setting up a stabilizing mechanism, the contact area between the patch 1 and the patient's skin can be increased, improving the stability of the device's fit and ensuring that the hemostatic cotton remains in contact with the puncture point. The specific operation is as follows: When the patch 1 is attached to the patient's skin, the stabilizing plates 31 on the front and back sides will also be attached to the patient's skin, increasing the contact area with the patient's skin, improving the stability of the device's fit, and ensuring that the hemostatic cotton remains in contact with the puncture point. At the same time, under the action of the second torsion spring 311, the stabilizing plates 31 can also rotate with the patient's limb movements, thereby always maintaining a state of contact with the patient's skin and stabilizing the front and back sides of the patch 1.

[0048] like Figure 1 and Figure 13 As shown, it also includes a reinforcement mechanism, which can reinforce the fixed cylinder 3 to prevent tilting. The reinforcement mechanism includes a connecting block 32, a second connecting rod 33 and a third connecting rod 34. The left end of the restraint strap 101 is fixedly connected to the connecting block 32, the second connecting rod 33 is rotatably connected to the connecting block 32, the upper end of the second connecting rod 33 is rotatably connected to the third connecting rod 34, and the right end of the third connecting rod 34 is fixedly connected to the left side of the fixed cylinder 3.

[0049] By setting up a reinforcement mechanism, the fixing cylinder 3 can be kept vertical, preventing the adhesive block 1 from tilting and causing the hemostatic cotton to contact the puncture point and press effectively. The specific operation is as follows: the connecting block 32 is fixedly connected to the left end of the restraint band 101. The connecting block 32 and the fixing cylinder 3 are connected together by the second connecting rod 33 and the third connecting rod 34 to prevent the fixing cylinder 3 from tilting and to prevent the adhesive block 1 from tilting and affecting the contact between the hemostatic cotton and the puncture point. The second connecting rod 33 and the third connecting rod 34 are both rotatable connections, which will not affect the length adjustment of the restraint band 101.
