Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a PICC catheterization compression auxiliary device. Background Art

[0002] PICC catheterization refers to puncturing and inserting a special catheter through a peripheral vein (such as the cephalic vein, basilic vein, median cubital vein and other thick superficial veins in the elbow), and then passing through the axillary vein, subclavian vein and innominate vein in sequence along the blood vessels, and finally entering the superior vena cava, and positioning the tip of the catheter in these central veins. This catheter can provide patients with medium- to long-term intravenous infusion therapy.

[0003] Most of the currently available PICC catheter compression assist devices first insert the PICC catheter needle into the patient's peripheral vein, and then compress and fix the PICC catheter with a dressing-type medical product. However, in actual use, medical staff need to calibrate the PICC catheter position and compress and fix the PICC catheter with a dressing-type medical product. If the medical staff fails to compress the PICC catheter properly, it may easily lead to bleeding at the puncture site, poor infusion, or drug leakage. At the same time, the compression strength of the PICC catheter cannot be adjusted according to the dimensions of the patient's arm, causing discomfort to the patient's arm.

[0004] Therefore, there is an urgent need for a PICC catheter compression auxiliary device to solve the existing technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a PICC catheter compression auxiliary device to solve the problems raised in the above background technology.

[0008] As a further improvement of the present technical solution, the rotating mechanism includes a rotating gear, a plug-in rod is connected to the left end of the rotating gear surface, and a sleeve rod is telescopically sleeved on the right end of the rotating gear surface. The left side of the sleeve rod surface corresponds to the position of the plug-in rod surface, and synchronously drives the plug-in rod to telescopically adjust at the left end of the rotating gear surface.

[0009] As a further improvement of the present technical solution, the tensioning mechanism includes a tensioning groove, a roller is installed on the right side of the tensioning groove, an elastic band is rotatably connected to the outer surface of the roller, an elastic spring rod is installed at the center position of the bottom left side of the tensioning groove, a baffle is installed on the top surface of the elastic spring rod, a positioning block is slidably connected to the upper surface of the baffle, a plug-in groove is opened at the center position of the surface of the positioning block, a connecting plate is connected to the right side of the surface of the positioning block, a sliding groove is opened at the center position of the bottom inside the tensioning groove, a groove is opened at the center position of the left side of the surface of the tensioning groove, a clamping block is movably sleeved at the bottom right side of the surface of the tensioning groove, the plug-in rod is clamped and extruded by the sleeve rod and the plug-in groove, the positioning block slides to the surface of the sliding groove, and then the elastic spring rod lifts the baffle, and positions the right side of the tensioning groove surface through the clamping block, so that the left side of the tensioning groove surface is tilted.

[0010] As a further improvement of the present technical solution, the clamping mechanism includes a clamping groove, a through groove is opened on the left side inside the clamping groove, a positioning groove is opened on the right side of the surface of the clamping groove, a clamping ring is installed at the center position of the surface of the positioning groove, a retaining ring is slidably connected to the inner wall of the clamping ring, a clamping plate is movably installed on the right side of the through groove surface, a mounting rod is installed at the center position of the front end surface of the clamping plate, a limiting groove is opened on the surface of the mounting rod, a medicine groove is opened on the upper surface of the clamping plate, a through groove runs through the right side of the surface of the connecting plate and contacts with the surface of the clamping plate, and the retaining ring is rotatably connected to the inner wall surface of the clamping ring through a plug-in rod.

[0011] As a further improvement of the technical solution, the surface of the positioning groove is correspondingly connected to the surface of the clamping ring, and the plug-in rod is rotated to the surface of the positioning groove through the rotating gear and is rotatably sleeved with the inside of the clamping ring.

[0013] As a further improvement of the present technical solution, one side of the sleeve surface corresponds to the position of the sleeve rod, and the piston cylinder telescopes on the second sleeve surface, driving the sleeve ring to move and generating thrust on the sleeve rod. Since the left side of the sleeve rod surface corresponds to the position of the plug-in rod surface, the sleeve rod pushes the plug-in rod to engage with the corresponding plug-in groove.

[0014] As a further improvement of the technical solution, a medicine is clamped at the center of the surface of the card plate, and the upper surface of the card plate is connected to the surface of the medicine groove at a corresponding position.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The PICC catheter insertion compression auxiliary device, after inserting the catheter into the patient's peripheral vein through puncture, pushes the piston cylinder to the left, so that the sleeve ring slides to the left side on the sleeve rod, and simultaneously drives the plug-in rod to move into the elastic groove, and engages with the plug-in groove accordingly, so that the positioning block slides into the elastic groove and separates from the baffle, effectively making the elastic spring rod no longer blocked by the baffle, and under the elastic force, the right side of the elastic groove surface is positioned and sleeved by the clamping block, thereby causing the left side of the elastic groove surface to be lifted upward, forming an inclined angle with the medical tape, so that the elastic band in the elastic groove is easily pulled out, and the patient's arm is tied from the outside of the medical tape, effectively compressing the PICC catheter placement mechanism.

[0017] 2. The PICC catheter insertion compression auxiliary device makes the positioning block slide toward the surface of the slide groove and engage with the slide groove by correspondingly engaging and squeezing the plug-in rod with the plug-in groove. Since the upper surface of the positioning block is connected to the elastic band, the medical staff can rotate the rotating gear, and then the plug-in rod drives the positioning block to slide on the surface of the slide groove, so that the elastic band extends from the groove position opened on the left side of the elastic groove, and the binding operation can be performed from one end of the patient's arm.

[0018] 3. The PICC tube compression auxiliary device is configured by tying an elastic band from one end of the patient's arm and extending it to the position of the clamping slot. After the plug-in rod passes through the positioning slot, it is clamped with the inside of the clamp ring. At the same time, the limit groove provided has a clamping effect on the surface of the elastic band. The rotating gear is rotated again to rotate the plug-in rod, driving the ring to rotate on the inner wall of the clamp ring, and the opening position of the clamp ring and the positioning slot is blocked, so that the elastic band can be effectively clamped inside the clamping slot, and the PICC tube compression operation can be directly and effectively performed on the patient.

[0019] 4. The PICC catheter insertion compression auxiliary device, after the positioning block is slidably engaged with the slide groove, synchronously drives the connecting plate on the right side of the positioning block surface to slide inward. Since one end of the connecting plate extends through the through groove to the inside of the engaging groove, the connecting plate can squeeze the card plate, causing the card plate to slide, and can squeeze the medicine engaged by the card plate, effectively squeezing the medicine onto the surface of the medicine groove, making it convenient for medical staff to apply externally on the patient's acupuncture site, which has the effect of reducing the incidence of phlebitis and relieving the symptoms of phlebitis, and at the same time avoids the need for medical staff to take medicine from the medical box for external application, thereby improving the efficiency of nursing work on the patient's acupuncture site.

[0033] Example

[0034] See also Figure 1 - Figure 7 As shown, the purpose of this embodiment is to provide a PICC catheter insertion compression auxiliary device, including a PICC catheter insertion mechanism 100, a rotating mechanism 200, a tensioning mechanism 300 and a clamping mechanism 400, the rotating mechanism 200 is rotatably connected to the right side of the outer surface of the PICC catheter insertion mechanism 100, the tensioning mechanism 300 and the clamping mechanism 400 are movably installed on the left side of the outer surface of the PICC catheter insertion mechanism 100 through the rotating mechanism 200, an elastic band 303 is movably installed inside the tensioning mechanism 300, a plug-in rod 202 is connected to one side of the surface of the rotating mechanism 200, the elastic band 303 rotates inside the tensioning mechanism 300 through the plug-in rod 202, a limiting groove 406 is arranged inside the clamping mechanism 400, the elastic band 303 rotates to extend to the inside of the clamping mechanism 400, and is movably clamped with the surface of the limiting groove 406;

[0035] After the front end of the PICC catheter placement mechanism 100 is punctured and inserted into the patient's peripheral vein, the medical staff rotates and adjusts the rotating mechanism 200, and inserts the connecting rod 202 into the elastic mechanism 300, corresponding to the elastic band 303 installed in the elastic mechanism 300. The elastic band 303 can be rotated and extended out from the elastic mechanism 300, and one end of the elastic band 303 can be movably clamped in the clamping mechanism 400, and then the elastic band 303 can be tied to the surface of the patient's arm to compress the PICC catheter placement mechanism 100 as a whole on the patient's arm, avoiding first puncturing the PICC catheter placement mechanism 100 as a whole into the patient's peripheral vein, and then taking out the medical tape 107 for compressing the PICC catheter placement mechanism 100 as a whole from the medical box, which simplifies the process of compressing the PICC catheter placement mechanism 100 as a whole, and is convenient and simple to operate.

[0036] Considering the need to achieve the protection function of the PICC catheter placement mechanism 100, in this embodiment, the PICC catheter placement mechanism 100 includes a catheter 101, a lumen 102 is fixedly sleeved on the right side of the surface of the catheter 101, a first sleeve 103 is fixedly sleeved on the right side of the surface of the lumen 102, a second sleeve 104 is fixedly sleeved on the right side of the surface of the first sleeve 103, a piston cylinder 105 is movably sleeved on the right side of the surface of the second sleeve 104, a ring 106 is connected to the left side of the surface of the piston cylinder 105, a medical tape 107 is connected to the lower surface of the second sleeve 104, and the piston cylinder 105 is telescopically sleeved on the left side of the surface of the second sleeve 104 through the ring 106;

[0037] Furthermore, the first sleeve 103 and the second sleeve 104 are sleeved together, and the catheter 101 is passed through the through hole opened at the center position of the first sleeve 103 and the second sleeve 104. Finally, one end of the catheter 101 is fixedly sleeved inside the first sleeve 103 and the second sleeve 104 through the piston cylinder 105. After one end of the catheter 101 is inserted into the patient's peripheral vein, the medical staff adjusts the piston cylinder 105 on the right side of the second sleeve 104 surface through the sleeve ring 106, and the sleeve depth between the piston cylinder 105 and the second sleeve 104 can be adjusted, and the rotating mechanism 200, the tensioning mechanism 300 and the clamping mechanism 400 that are subsequently set are adjusted;

[0038] The improvement lies in that the first sleeve 103 and the second sleeve 104 can position and sleeve the catheter 101 and fix it through the provided lumen 102. After the catheter 101 is sleeved inside the first sleeve 103 and the second sleeve 104, the piston cylinder 105 and the ring 106 are sleeved on the right side of the surface of the second sleeve 104. After the left side of the surface of the catheter 101 is punctured and inserted into the patient's peripheral vein, when it is necessary to perform a compression operation on the PICC catheter placement mechanism 100, the piston cylinder 105 is telescopically adjusted on the right side of the surface of the second sleeve 104 through the ring 106, and the rotating mechanism 200, the loosening mechanism 300 and the clamping mechanism 400 provided on the surface of the PICC catheter placement mechanism 100 can be effectively adjusted to compress the PICC catheter placement mechanism 100 on the surface of the patient's arm.

[0039] Considering the need to realize the rotation of the rotating mechanism 200, in this embodiment, the rotating mechanism 200 includes a rotating gear 201, a plug-in rod 202 is connected to the left end of the rotating gear 201 surface, and a sleeve rod 203 is telescopically sleeved to the right end of the rotating gear 201 surface. The left side of the sleeve rod 203 surface corresponds to the surface position of the plug-in rod 202, and synchronously drives the plug-in rod 202 to be telescopically adjusted at the left end of the rotating gear 201 surface.

[0040] Furthermore, the piston cylinder 105 is telescopically adjusted on the right side of the second sleeve 104 surface by the provided sleeve ring 106, so that the sleeve rod 203 is pushed by the sleeve ring 106, driving the plug rod 202 to move inside the tensioning mechanism 300. When the plug rod 202 is engaged with the inside of the tensioning mechanism 300, the medical staff can rotate the rotating gear 201, synchronously driving the plug rod 202 to rotate on the surface of the rotating gear 201, and effectively extending the elastic band 303 movably installed inside the tensioning mechanism 300 and tying it to the surface of the patient's arm;

[0041] The improvement lies in that the rotating mechanism 200 is integrally movably connected to the surface of the PICC catheter placement mechanism 100, which can avoid the medical staff from taking out the medical tape 107 from the medical box and then pressing the PICC catheter placement mechanism 100 on the patient's arm. At the same time, the connecting rod 202 can be inserted into the patient's peripheral vein through a puncture on the left side of the surface of the catheter 101. The medical staff directly rotates the rotating gear 201, and extends the elastic band 303 from the inside of the elastic mechanism 300 through the connecting rod 202, and wraps it around the surface of the patient's arm for one circle, so that the PICC catheter placement mechanism 100 can be pressed on the surface of the patient's arm, which is convenient and simple to operate.

[0042] Considering the need to realize the adjustment function of the tension mechanism 300, in this embodiment, the tension mechanism 300 includes an elastic groove 301, a roller 302 is installed on the right side of the elastic groove 301, and an elastic belt 303 is rotatably connected to the outer surface of the roller 302. An elastic spring rod 304 is installed at the center of the bottom left side of the elastic groove 301, and a baffle 305 is installed on the top surface of the elastic spring rod 304. A positioning block 306 is slidably connected to the upper surface of the baffle 305. A plug-in slot 307 is opened at the center of the surface of the positioning block 306. The right side of the surface of the positioning block 306 A connecting plate 308 is connected, a sliding groove 309 is provided at the center of the bottom inner side of the elastic groove 301, a groove 310 is provided at the center of the left side of the surface of the elastic groove 301, and a clamping block 311 is movably sleeved at the bottom right side of the surface of the elastic groove 301. The plug rod 202 is correspondingly clamped and squeezed with the plug groove 307 through the sleeve rod 203, and the positioning block 306 slides to the surface of the sliding groove 309, so that the elastic spring rod 304 lifts the baffle 305, and the right side of the surface of the elastic groove 301 is positioned through the clamping block 311, so that the left side of the surface of the elastic groove 301 is tilted;

[0043] Furthermore, after the plug-in rod 202 is correspondingly engaged with the plug-in slot 307, it continues to be pushed into the interior of the tensioning mechanism 300, so that the positioning block 306 slides on the surface of the baffle 305 and separates from the baffle 305. Since the lower surface of the baffle 305 corresponds to the position of the elastic spring rod 304, the elastic spring rod 304 is not subjected to pressure and pops up from the position of the baffle 305. Since the upper end of the tensioning slot 301 is movably engaged with the set engaging block 311, the lower end of the tensioning slot 301 can be pushed and tilted by the elastic spring rod 304, and the upper surface of the set positioning block 306 is connected to the elastic band 303. When the medical staff rotates the rotating gear 201, the plug-in rod 202 drives the elastic band 303 to extend from the inside of the elastic slot 301, and the rotating gear 201 rotates on the surface of the patient's arm to perform circle binding;

[0044] The improvement lies in that: the plug-in rod 202 generates a thrust on the positioning block 306, so that the baffle 305 is separated from the elastic spring rod 304, and the elastic spring rod 304 pushes the elastic groove 301 to be inclined and spread out on one side of the surface of the PICC catheter placement mechanism 100. The medical staff rotates the rotating gear 201, and under the connection between the plug-in rod 202 and the positioning block 306, the elastic band 303 is rotated and extended out from the elastic groove 301, and rotates along the surface of the patient's arm, and clamps one side of the elastic band 303 with the clamping mechanism 400, so that the PICC catheter placement mechanism 100 can be pressed on the surface of the patient's arm to play a clamping role. At the same time, the medical tape 107 provided further plays a fixing effect.

[0045] Considering the need to realize the clamping effect of the clamping mechanism 400, in this embodiment, the clamping mechanism 400 includes a clamping groove 401, a through groove 402 is opened on the left side of the inside of the clamping groove 401, a positioning groove 403 is opened on the right side of the surface of the clamping groove 401, a clamping ring 407 is installed at the center position of the surface of the positioning groove 403, and a retaining ring 408 is slidably connected to the inner wall of the clamping ring 407, a clamping plate 404 is movably installed on the right side of the surface of the through groove 402, a mounting rod 405 is installed at the center position of the front end surface of the clamping plate 404, a limiting groove 406 is opened on the surface of the mounting rod 405, a medicine groove 409 is opened on the upper surface of the clamping plate 404, the right side of the surface of the connecting plate 308 passes through the through groove 402 and contacts with the surface of the clamping plate 404, and the retaining ring 408 is rotatably connected to the inner wall surface of the clamping ring 407 through the plug-in rod 202;

[0046] Furthermore, after the positioning block 306 is pushed to the position of the slide groove 309 by the plug rod 202, the provided connecting plate 308 slides inward synchronously. Since one end of the connecting plate 308 passes through the through groove 402 and extends to the inside of the clamping mechanism 400, the clamping plate 404 is effectively squeezed and pushed. The surface of the clamping plate 404 is clamped with medicine, which is generally a polysulfonated mucopolysaccharide cream. Under the force of squeezing, the ointment produced by the extrusion of the medicine can be accumulated on the surface of the medicine groove 409, and the medical staff can effectively and timely take care of the patient's acupuncture position. At the same time, after the elastic band 303 rotates and extends to the inside of the clamping groove 401, it contacts the surface of the provided limiting groove 406, and at the same time, the plug rod 202 is clamped inside the clamping ring 407 through the positioning groove 403, and under the rotation of the plug rod 202, the retaining ring 408 is driven to rotate on the inner wall of the clamping ring 407, so that the retaining ring 408 rotates to the intersection of the positioning groove 403 and the clamping ring 407.

[0047] The improvement lies in that: under the squeezing force of the clamping plate 404, the ointment accumulates on the surface of the medicine groove 409, which makes it convenient for medical staff to directly apply the ointment to the patient's acupuncture site, thereby improving the effect of reducing the incidence of phlebitis and relieving the symptoms of phlebitis. At the same time, it also avoids the need for medical staff to take the medicine out of the medical box, thereby speeding up the care efficiency of the patient's acupuncture site. At the same time, the medical staff rotates the rotating gear 201, which can effectively clamp the elastic band 303 inside the clamping groove 401, and the tightness of the elastic band 303 can be adjusted according to the dimensions of different patients' arms. On the one hand, a comfortable effect is achieved, and on the other hand, the PICC catheter placement mechanism 100 is effectively pressed as a whole against the surface of the patient's arm.

[0048] In summary, the working principle of the present invention is as follows: after the catheter 101 is inserted into the patient's peripheral vein through puncture, the piston cylinder 105 is pushed to the left, so that the sleeve ring 106 slides the sleeve rod 203 to the left, and simultaneously drives the plug-in rod 202 to move into the elastic groove 301, and engages with the plug-in groove 307 accordingly, so that the positioning block 306 slides into the elastic groove 301 and separates from the baffle 305, effectively making the elastic spring rod 304 no longer blocked by the baffle 305. Under the elastic force, the right side of the elastic groove 301 surface is positioned and sleeved by the clamping block 311, thereby lifting the left side of the elastic groove 301 surface upward and engaging with the medical tape 107. The elastic band 303 is at an inclined angle, which is convenient for pulling out the elastic band 303 in the elastic groove 301, and binding the patient's arm from the periphery of the medical tape 107, effectively compressing the PICC catheter placement mechanism 100, and the plug-in rod 202 is correspondingly engaged and squeezed with the plug-in groove 307, so that the positioning block 306 slides toward the surface of the slide groove 309 and is engaged with the slide groove 309. Since the upper surface of the positioning block 306 is connected with the elastic band 303, the medical staff can rotate the rotating gear 201, thereby allowing the plug-in rod 202 to drive the positioning block 306 to slide on the surface of the slide groove 309, so that the elastic band 303 extends from the groove 310 position opened on the left side of the elastic groove 301, and can be The patient's arm is tied up at one end, and the elastic band 303 is tied from one end of the patient's arm and extended to the position of the clamping groove 401. After the plug rod 202 passes through the positioning groove 403, it is clamped with the inside of the clamp ring 407. At the same time, the limit groove 406 provided has a clamping effect on the surface of the elastic band 303. The rotating gear 201 is rotated again to rotate the plug rod 202, driving the ring 106 to rotate on the inner wall of the clamp ring 407, and the opening position of the clamp ring 407 and the positioning groove 403 is blocked, so that the elastic band 303 can be effectively clamped inside the clamping groove 401, and the PICC tube compression operation can be directly and effectively performed on the patient. The positioning block 306 After sliding and engaging with the slide groove 309, the connecting plate 308 on the right side of the surface of the positioning block 306 is synchronously driven to slide inward. Since one end of the connecting plate 308 passes through the through groove 402 and extends to the inside of the engaging groove 401, the connecting plate 308 can squeeze the clamping plate 404, causing the clamping plate 404 to slide, and can squeeze the medicine clamped by the clamping plate 404, effectively squeezing the medicine to the surface of the medicine groove 409, making it convenient for medical staff to apply externally on the patient's acupuncture position, which has the effect of reducing the incidence of phlebitis and alleviating the symptoms of phlebitis, and at the same time avoids the need for medical staff to take medicine from the medical box for external application, thereby improving the efficiency of nursing work at the patient's acupuncture position.
