Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a catheter care and fixation device for intravenous therapy. Background Technology

[0002] A venous catheter is a medical catheter inserted into a patient's vein at one end and placed outside the patient's body at the other end for injecting medication or drawing blood. Venous catheters remain in the patient's body for anywhere from three to five days to one or two months. The end of the venous catheter outside the patient's body has a sealed cap. During repeated injections or fluid aspirations, the back-and-forth pulling of the catheter can easily cause the dressing to detach from the patient's skin or allow air to enter, potentially causing infection at the injection site. This also increases the workload for medical staff. Furthermore, traditional venous catheters require medical tape to secure the catheter and sealing cap after the needle is fixed. However, this tape can easily detach during prolonged patient movement, pulling on the catheter and even causing the dressing to fall off. Therefore, providing a more practical and less demanding venous catheter care and fixation device is of significant practical importance. Summary of the Invention

[0003] The present invention provides a catheter care and fixation device for intravenous therapy, which aims to solve the problems of existing technology when fixing indwelling needles for intravenous therapy, where the dressing film is easy to fall off from the patient's body surface or allow air to enter. After fixing the needle of a traditional intravenous catheter, medical tape is still needed to fix the catheter and the sealing cap. However, the use of medical tape is also prone to peeling off during prolonged patient movement, which can pull on the catheter or even cause the dressing film to fall off.

[0004] This invention provides a catheter care and fixation device for intravenous therapy, including a dressing film. The dressing film has a transparent observation window in the middle. An adhesive tape is fixedly adhered to the inner side of the dressing film. Tensioning and anti-detachment straps are fixedly connected to both outer sides of the dressing film. A soft silicone sheet is fixedly connected to the top of the dressing film. A U-shaped groove is provided in the middle of the surface of the soft silicone sheet. The U-shaped groove is opposite to the observation window. A catheter clamping mechanism and a catheter limiting mechanism are provided on both sides of the surface of the soft silicone sheet located at the U-shaped groove. A catheter limiting groove is opened at one end of each side of the soft silicone sheet.

[0005] An arc-shaped silicone pad is fitted over the two tensioning and anti-detachment straps. The inner side of the arc-shaped silicone pad is tightly fitted to the outer side of the dressing film. A moisture removal mechanism is installed inside the arc-shaped silicone pad.

[0007] In one embodiment of the present invention, the tensioning anti-detachment strap is made of non-woven fabric. One end of the tensioning anti-detachment strap is fixedly connected to the outside of the adhesive film. The other end of one tensioning anti-detachment strap is fixedly connected to a Velcro letter face, and the other end of the other tensioning anti-detachment strap is fixedly connected to a Velcro female face. The two tensioning anti-detachment straps are glued and fixed through the groove opened in the arc-shaped silicone pad.

[0008] In one embodiment of the present invention, the catheter clamping mechanism includes a fixing seat fixedly connected to the top of a soft silicone sheet. A first crescent seat is rotatably connected to the top of the fixing seat. A second crescent seat fixedly connected to the top of the soft silicone sheet is provided on one side of the first crescent seat. An arc-shaped groove is formed in the middle of the second crescent seat. A first placement groove is reserved between the second crescent seat and the first crescent seat. A rotating rod is inserted through the middle of the first crescent seat. A knob is fixedly connected to one end of the rotating rod. An elastic locking mechanism is connected to the other end of the rotating rod through the arc-shaped groove. A wedge-shaped pressure block is fixedly connected to the middle of the rotating rod. The wedge-shaped pressure block is placed in the first placement groove.

[0009] In one embodiment of the present invention, the elastic locking mechanism includes a sleeve fixedly connected to the other end of the rotating rod, a spring fixedly connected inside the sleeve, a pressure block fixedly connected to one end of the spring and sleeved outside the sleeve, a silicone pad fixedly connected to one end of the sleeve, and a friction plate with a wedge-shaped cross-section provided on one side of the silicone pad, the friction plate being fixedly connected to the outside of the second crescent.

[0010] In one embodiment of the present invention, the catheter limiting mechanism includes a rotating seat fixedly connected to the top of a soft silicone sheet, and a second catheter placement groove is provided in the middle of the rotating seat. Anti-slip pads are fixedly provided inside both the second and first catheter placement grooves.

[0011] In one embodiment of the present invention, the desiccant mechanism includes an air extraction cylinder fixedly connected inside an arc-shaped silicone pad. The air outlet of the air extraction cylinder is connected to a one-way valve. One end of the pull rod of the air extraction cylinder is rotatably connected to an L-shaped pull rod via a pin. The air inlet of the air extraction cylinder is connected to an air extraction pipe. One end of the air extraction pipe passes through the arc-shaped silicone pad and communicates with the interior of the observation window. A notch is provided at the position directly opposite the pull rod of the air extraction cylinder, and the pull rod is placed inside the notch.

[0012] In one embodiment of the present invention, the protective mechanism includes an elastic net fixedly connected to one end of an arc-shaped silicone pad, a fixing rod fixedly connected to one end of the elastic net, the fixing rod being inserted into a rod limiting groove provided at the other end of the arc-shaped silicone pad, and the width of the elastic net being adapted to the width of the adhesive film.

[0013] In one embodiment of the present invention, a net bag is fixedly connected to the inner side of the elastic net, the size of the net bag is adapted to the size of the syringe, and an elastic band is sewn at the opening of the net bag.

[0014] In one embodiment of the present invention, a patient information identification piece is fixedly connected to the other end of the arc-shaped silicone pad, and a QR code label and a writing sticker are affixed to the surface of the information identification piece.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) The dressing film allows for quick and easy attachment of the indwelling needle to the patient's skin. The observation window facilitates needle observation by medical staff. The anti-detachment strap tightens the dressing film to prevent it from falling off the patient's skin, reducing the workload of medical staff. The curved silicone pad, after tightening the anti-detachment strap and securing it with Velcro, is placed at the bottom of the patient's wrist, which can also prevent the dressing film from falling off due to wrist bending. The soft silicone sheet, together with the catheter limiting groove, catheter clamping mechanism, and catheter limiting mechanism, can limit and fix the catheter, effectively preventing the dressing film from detaching from the patient's skin due to traction, further reducing the workload of medical staff. The catheter clamping mechanism allows for convenient clamping of the catheter, effectively preventing backflow. At the same time, controlling the catheter clamping can also control the flow rate of drug injection, making it highly practical. The dehumidification mechanism can extract moisture generated inside the dressing film during long-term intravenous treatment, further ensuring the stability of the dressing film's adhesion to the patient's skin.

[0017] 2) The net bag set by the protective mechanism can cover the sealing cap, soft silicone sheet and catheter to prevent pulling on the catheter. It is more convenient and stable than the traditional method of fixing with medical tape. The net bag can also hold the syringe for drug administration and can also quickly fix the syringe to ensure convenient intravenous treatment. Moreover, the catheter care and fixation device has a relatively simple structure and is easy to use, and has good application prospects in the field of intravenous treatment.

[0035] Example

[0036] Please see Figure 1-8A catheter care and fixation device for intravenous therapy includes a dressing film 1, a transparent observation window 11 in the middle of the dressing film 1, an adhesive tape 12 fixedly bonded to the inner side of the dressing film 1, tensioning anti-detachment tapes 13 fixedly connected to both sides of the outer side of the dressing film 1, a soft silicone sheet 2 fixedly connected to the top of the dressing film 1, a U-shaped groove 21 in the middle of the surface of the soft silicone sheet 2, the U-shaped groove 21 being opposite to the observation window 11, a catheter clamping mechanism 22 and a catheter limiting mechanism 23 on both sides of the surface of the soft silicone sheet 2 located at the U-shaped groove 21, and a catheter limiting groove 24 opened at one end of each side of the soft silicone sheet 2;

[0037] Specifically, by using a relatively inexpensive dressing film 1 as the fixing component for the indwelling needle, the structure is simple and easy to use. The observation window 11 allows medical staff to observe the needle insertion into the patient's body, enabling timely intervention in case of needle dislodgement or moisture buildup inside the dressing film 1. The two tensioning anti-dislodgement straps 13 increase the stability of the dressing film 1 on the patient's body surface after tensioning. The soft silicone sheet 2, after the indwelling needle is fixed by the dressing film 1, allows for initial catheter positioning using the catheter limiting groove 24 on its side. The catheter is then passed through a catheter clamping machine. The catheter limiting mechanism 22 and the catheter limiting mechanism 23 can provide secondary limiting and fixation of the catheter to prevent it from falling off the soft silicone sheet 2. The soft silicone sheet 2 has a certain degree of flexibility, and the position of the sealing cap at one end of the cannula can be adjusted by folding the soft silicone sheet 2, making it convenient for medical staff to perform injections or fluid aspiration examinations on patients through the sealing cap. The catheter clamping mechanism 22 can quickly clamp the catheter to effectively prevent backflow. At the same time, the catheter clamping mechanism 22 can also adjust the clamping of the catheter, especially during injection treatment, to adjust the flow rate of the injected drug, increasing the practicality of the catheter care and fixation device.

[0038] Among them, the two tensioning anti-detachment straps 13 are fitted with arc-shaped silicone pads 3 on the outside. The inner side of the arc-shaped silicone pads 3 is tightly fitted with the outer side of the dressing film 1. The arc-shaped silicone pads 3 are equipped with a moisture removal mechanism 31 inside. The ends of the arc-shaped silicone pads 3 are equipped with a protective mechanism 4 that is fitted on the outer side of the dressing film 1 to fix the catheter and the drug delivery syringe.

[0039] Specifically, the curved silicone pad 3 can be fixed to the bottom of the dressing film 1 after the anti-detachment strap 13 is tightened and fixed, and provides limiting support for the patient's wrist, effectively preventing the adhesive tape 12 of the dressing film 1 from lifting and detaching due to the movement of the patient's wrist. The dehumidification mechanism 31 can extract moisture generated inside the dressing film 1, further ensuring the practicality of the catheter care fixation device. The protective mechanism 4 can cover the sealing cap, soft silicone sheet 2 and catheter, preventing the catheter from being pulled by daily activities. It is more convenient and stable than the traditional fixation method using medical tape.

[0040] In this embodiment: the adhesive tape 12 has an opening in the middle that matches the size of the observation window 11, the edge of the adhesive tape 12 is provided with a skin-friendly gel layer 121, and the inner side of the adhesive tape 12 is bonded with release paper 122.

[0041] Specifically, the release paper 122 can protect the adhesive tape 12 and the skin-friendly gel layer 121. At the same time, it is also simple to use the dressing film 1 to fix the indwelling needle tip. Just tear off the release paper 122 to stick the dressing film 1 to the patient's body surface. It is convenient to use. While the skin-friendly gel layer 121 is sticking to the patient's body surface, it can also increase the comfort of the adhesive tape 12 in contact with the body surface.

[0042] In this embodiment: the tensioning anti-detachment strap 13 is made of non-woven fabric. One end of the tensioning anti-detachment strap 13 is fixedly connected to the outside of the adhesive film 1. The other end of one tensioning anti-detachment strap 13 is fixedly connected to the Velcro letter face 131, and the other end of the other tensioning anti-detachment strap 13 is fixedly connected to the Velcro female face 132. The two tensioning anti-detachment straps 13 pass through the groove 32 opened in the arc-shaped silicone pad 3 and are glued and fixed.

[0043] Specifically, after fixing the needle of the indwelling needle to the patient's body surface using the dressing film 1, the tensioning anti-detachment strap 13 can be passed through the groove 32 and tightened. The Velcro face 131 and the Velcro face 132 are then bonded together to tighten and fix the two tensioning anti-detachment straps 13. This increases the firmness of the dressing film 1 on the patient's body surface and also prevents the needle from rotating at the bottom of the dressing film 1.

[0044] In this embodiment: the catheter clamping mechanism 22 includes a fixed seat 221 fixedly connected to the top of the soft silicone sheet 2. A first crescent seat 222 is rotatably connected to the top of the fixed seat 221. A second crescent seat 223 fixedly connected to the top of the soft silicone sheet 2 is provided on one side of the first crescent seat 222. An arc-shaped groove 2231 is opened in the middle of the second crescent seat 223. A first tube placement groove 224 is reserved between the second crescent seat 223 and the first crescent seat 222. A rotating rod 225 is inserted through the middle of the first crescent seat 222. A knob 228 is fixedly connected to one end of the rotating rod 225. An elastic locking mechanism 226 is connected to the other end of the rotating rod 225 through the arc-shaped groove 2231. A wedge-shaped tube pressing block 227 is fixedly connected to the middle of the rotating rod 225. The wedge-shaped tube pressing block 227 is placed in the first tube placement groove 224.

[0045] Specifically, when it is necessary to clamp and limit the catheter using the catheter clamping mechanism 22, the first half-moon seat 222 can be rotated first, so that the rotating rod 225 and the wedge-shaped pressure block 227 can be rotated out of the first placement groove 224. Then, the catheter is placed in the first placement groove 224, and the first half-moon seat 222 is rotated again, so that the wedge-shaped pressure block 227 can be rotated into the first placement groove 224. At the same time, the rotating rod 225 is also rotated into the arc groove 2231. The elastic locking mechanism 226 is placed outside the arc groove 2231. At this time, the first placement groove 224 can be used to limit the catheter.

[0046] In this embodiment: the elastic locking mechanism 226 includes a sleeve 2261 fixedly connected to the other end of the rotating rod 225. A spring 2262 is fixedly connected inside the sleeve 2261. A pressure block 2265 fitted outside the sleeve 2261 is fixedly connected to one end of the spring 2262. A silicone pad 2263 is fixedly connected to one end of the sleeve 2261. A friction plate 2264 with a wedge-shaped cross section is provided on one side of the silicone pad 2263. The friction plate 2264 is fixedly connected to the outside of the second crescent seat 223.

[0047] Specifically, when it is necessary to clamp the catheter, medical staff can rotate the knob 228, which will drive the rotating rod 225 and the wedge-shaped clamping block 227 to rotate. When the rotating wedge-shaped clamping block 227 rotates to the lowest position, one end of the wedge-shaped clamping block 227 clamps the catheter. As the rotating rod 225 rotates, the sleeve 2261 and the clamping block 2265 also rotate. The rotating clamping block 2265 comes into frictional contact with the friction plate 2264. Since the friction plate 2264 has a wedge-shaped cross section, the frictional force between the clamping block 2265 and the friction plate 2264 increases as the clamping block 2265 rotates, and the spring 2262 is further tightened, which can prevent the rotating rod 225 from rotating on its own. This can effectively ensure the stability of the clamping of the catheter by the wedge-shaped clamping block 227. By adjusting the degree of clamping of the catheter by the wedge-shaped clamping block 227, the flow rate of the drug can be controlled during the injection process.

[0048] In this embodiment: the catheter limiting mechanism 23 includes a rotating seat fixedly connected to the top of the soft silicone sheet 2. A second tube placement groove is provided in the middle of the rotating seat. Anti-slip pads 5 are fixedly provided inside both the second tube placement groove and the first tube placement groove 224.

[0049] Specifically, by placing the catheter in the second placement groove, the catheter can be further restricted. The anti-slip plate 5 can increase the friction between the first placement groove 224, the second placement groove and the catheter, effectively preventing the catheter from detaching or sliding in the placement groove.

[0050] In this embodiment: the moisture removal mechanism 31 includes an air extraction cylinder 311 fixedly connected inside the arc-shaped silicone pad 3. The air outlet end of the air extraction cylinder 311 is connected to a one-way air valve 312. One end of the pull rod of the air extraction cylinder 311 is rotatably connected to an L-shaped pull rod 314 through a pin 313. The air inlet end of the air extraction cylinder 311 is connected to an air extraction pipe 315. One end of the air extraction pipe 315 passes through the arc-shaped silicone pad 3 and communicates with the interior of the observation window 11. A notch 33 is provided at the position where the arc-shaped silicone pad 3 and the pull rod of the air extraction cylinder 311 are directly opposite each other. The pull rod 314 is placed inside the notch 33.

[0051] Specifically, when moisture appears inside the dressing film 1, medical staff can rotate the lever 314 around the pin 313 so that the lever 314 can be turned out of the notch 33. Then, pull the lever and use the air pump 311 in conjunction with the air suction tube 315 to evacuate air from inside the dressing film 1. Use the one-way air valve 312 to expel the moisture from inside the dressing film 1. The arc-shaped silicone pad 3 is provided with an air outlet at the position opposite to the one-way air valve 312 to ensure that the moisture can be discharged smoothly. After the moisture is removed, the lever 314 is turned back into the notch 33 to prevent the lever 314 from scratching clothing or other items.

[0052] In this embodiment: the protective mechanism 4 includes an elastic net 41 fixedly connected to one end of the arc-shaped silicone pad 3. A fixing rod 42 is fixedly connected to one end of the elastic net 41. The fixing rod 42 is inserted into the rod limiting groove 43 provided at the other end of the arc-shaped silicone pad 3. The width of the elastic net 41 is adapted to the width of the adhesive film 1.

[0053] Specifically, by stretching the elastic net 41 over the outside of the dressing film 1, and then inserting the fixing rod 42 into the rod limiting groove 43, the stretched elastic net 41 can cover the sealing sleeve, soft silicone sheet 2 and tube, preventing the sealing sleeve, soft silicone sheet 2 and tube from rubbing against clothing or other items, causing the tube to be pulled and detached. Moreover, the stretched elastic net 41 can also fix the dressing film 1.

[0054] In this embodiment: a net bag 411 is fixedly connected to the inner side of the elastic net 41. The size of the net bag 411 is adapted to the size of the syringe. An elastic band 412 is sewn at the opening of the net bag 411.

[0055] Specifically, the syringe can be placed inside the net 411 to secure it, especially when continuous drug administration is required. The syringe can be connected to the sealing cap. The elastic band 412 can effectively prevent the syringe from slipping out of the net 411, further ensuring the practicality of the catheter care and fixation device in the process of intravenous treatment.

[0056] In this embodiment: The other end of the arc-shaped silicone pad 3 is fixedly connected to a patient information identification piece 34, and the surface of the information identification piece 34 is covered with a QR code label and a writing sticker.

[0057] Specifically, QR code stickers and writing stickers can be affixed to the patient information identification stickers 34. Patient information can be recorded using these stickers, making it convenient for medical staff to view the patient's treatment information in a timely manner and reducing the workload of medical staff in the daily care of patients.

[0058] When using a type of intravenous catheter care and fixation device:

[0059] Firstly, the dressing film 1 can quickly and easily attach and fix the indwelling needle to the patient's skin. The observation window 11 allows medical staff to easily observe the needle. Tightening the anti-detachment strap 13 can tighten the dressing film 1, preventing it from falling off the patient's skin and reducing the workload of medical staff. The curved silicone pad 3, after being secured with Velcro after tightening the anti-detachment strap 13, is placed at the bottom of the patient's wrist, further preventing the dressing film 1 from falling off due to wrist bending. The soft silicone sheet 2, in conjunction with the catheter limiting groove 24, catheter clamping mechanism 22, and catheter limiting mechanism 2... 3 can limit and fix the catheter, and effectively prevent the dressing film 1 from detaching from the patient's body surface due to traction, further reducing the daily nursing workload of medical staff. The catheter clamping mechanism 22 can easily clamp the catheter, effectively preventing backflow. At the same time, the flow rate of drug injection can be controlled by controlling the catheter clamping, which is highly practical. The dehumidification mechanism 31 can extract the moisture generated in the dressing film 1 during long-term intravenous treatment, further ensuring the stability of the dressing film 1 and the patient's body surface, which can also effectively reduce the daily nursing workload of medical staff.

[0060] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
