[0051] In the related art, disinfection cotton pads are usually placed in a bag, and medical staff hold the outer side of the bag and operate the disinfection cotton pads through the bag to wipe and disinfect the catheter connector. During the disinfection process, due to slippage between the bag and the disinfection cotton pad or rupture of the bag, the catheter connector is easily exposed from the bag, thereby contacting the medical staff's hands, causing cross infection between the catheter connector and the hands, posing a safety hazard.

[0052] The catheter joint disinfection device of the embodiment of the present application is provided with a mounting plate, a plurality of clamping members and a sleeve. The plurality of clamping members are arranged along the circumference of the mounting plate, and the fixed end of each clamping member is hinged to the mounting plate; the sleeve is slidably arranged on the outside of the mounting plate. When the sleeve slides relative to the mounting plate, it is sleeved on the outside of each clamping member, pushing the free end of each clamping member close to the center line of the mounting plate, so that the plurality of clamping members are surrounded to form a disinfection space. During disinfection, the catheter joint is inserted into the disinfection space where the disinfection cotton pad is placed, and the sleeve is rotated, and the mounting plate, the plurality of clamping members and the disinfection cotton pad are driven to rotate by the sleeve to wipe the catheter joint for disinfection. During the disinfection process, the medical staff holds the outside of the sleeve, and the catheter joint and the medical staff's hand are isolated by the sleeve to prevent the medical staff's hand from contacting the catheter joint, avoid cross infection between the catheter joint and the hand, and improve safety.

[0053] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] refer to Figure 1 and Figure 2 The embodiment of the present application provides a catheter connector disinfection device, comprising a mounting plate 100, a plurality of clamping members 200 and a sleeve 300, wherein the plurality of clamping members 200 are arranged along the circumference of the mounting plate 100. The fixed end 201 of each clamping member 200 is hinged to the mounting plate 100, and each clamping member 200 has a free end 207 opposite to the fixed end 201; the center line of the sleeve 300 is arranged colinearly with the center line of the mounting plate 100, and the sleeve 300 is slidably arranged on the outside of the mounting plate 100. The sleeve 300 has a first position in which the sleeve 300 is sleeved on the outside of each clamping member 200 so that the free end 207 of each clamping member 200 approaches the center line of the mounting plate 100 to enclose a disinfection space 208. The disinfection space 208 is used to accommodate a disinfection cotton sheet to disinfect the catheter connector. The sleeve 300 also has a second position away from each clamping member 200 so that the free ends 207 of each clamping member 200 are away from each other.

[0055] In the catheter joint disinfection device of the embodiment of the present application, the fixed end 201 of each clamping member 200 is hinged to the mounting plate 100, and when the sleeve 300 is slidably disposed on the outer side of the mounting plate 100, each clamping member 200 can rotate relative to the mounting plate 100, so that the free end 207 of each clamping member 200 is away from the center line of the mounting plate 100, that is, the sleeve 300 is located at the second position. At this time, a disinfection cotton sheet can be placed on each clamping member 200, and each clamping member 200 can support the disinfection cotton sheet.

[0056] When the sleeve 300 slides along the center line of the mounting plate toward the free end 207 of the clamping member 200, the sleeve 300 can push each clamping member 200 to rotate relative to the mounting plate 100, so that the free ends 207 of each clamping member 200 are close to each other. When the sleeve 300 slides to the outside of each clamping member 200, that is, when the sleeve 300 slides to the first position, each clamping member 200 is surrounded by a disinfection space 208, and the disinfection cotton sheet is located in the disinfection space 208. At this time, the catheter connector is inserted into the disinfection space 208, and then the sleeve 300 is rotated, and the sleeve 300 drives the mounting plate 100, multiple clamping members 200 and the disinfection cotton sheet to rotate, or the catheter connector is rotated, and the disinfection cotton sheet wipes the catheter connector for disinfection. During the disinfection process, the medical staff holds the outer side of the sleeve 300, and the disinfection space 208 and the medical staff's hands are isolated by the sleeve 300 to prevent the medical staff's hands from contacting the catheter connector, avoiding cross infection between the catheter connector and the hands, and improving safety.

[0057] refer to Figure 2 and Figure 3 The inner wall of the sleeve 300 is provided with a sliding groove 301 extending in a direction parallel to the center line of the mounting plate 100, and the mounting plate 100 is provided with a sliding protrusion 104, which is slidably arranged in the sliding groove 301. The sleeve 300 can move relative to the mounting plate 100 through the sliding protrusion 104 and the sliding groove 301. Exemplarily, the sliding between the sliding protrusion 104 and the sliding groove 301 can be damped sliding.

[0058] During the disinfection process, when the sleeve 300 is rotated, the sleeve 300 can drive the mounting disk 100 to rotate through the sliding protrusion 104 sliding in the sliding groove 301, thereby driving the disinfection cotton pad in the disinfection space 208 to wipe the catheter joint. The sliding groove 301 limits the sliding protrusion 104, which can prevent the sleeve 300 and the mounting disk 100 from rotating coaxially, thereby avoiding the situation where the disinfection space 208 cannot rotate relative to the catheter joint and cannot be wiped and disinfected.

[0059] There can be multiple sliding protrusions 104, and multiple sliding protrusions 104 can be evenly arranged along the circumference of the mounting plate 100. Correspondingly, the number of sliding grooves 301 in the sleeve 300 is the same as the number of sliding protrusions 104, and the sliding grooves 301 and the sliding protrusions 104 are arranged one by one, and each sliding protrusion 104 is slidably arranged in the corresponding sliding groove 301. Such an arrangement can improve the reliability of the connection between the sleeve 300 and the mounting plate 100, and at the same time can improve the stability of the sliding of the sleeve 300.

[0060] It is understandable that the sliding groove 301 can also be set on the mounting plate 100, and the sliding protrusion 104 can be set on the sleeve 300. As long as the sliding protrusion 104 can be slid into the sliding groove 301 so that the sleeve 300 and the mounting plate 100 can slide relative to each other, the embodiment of the present application does not make any specific limitations on this.

[0061] For example, reference Figure 4 A rib plate 105 is also provided on the mounting disk 100. The rib plate 105 is a right-angled triangle structure. One right-angled side of the rib plate 105 is connected to the mounting disk 100, and the other right-angled side of the rib plate 105 is connected to the sliding protrusion 104. The rib plate 105 can increase the connection strength between the sliding protrusion 104 and the mounting disk 100. In the process of the sleeve 300 driving the mounting disk 100 to rotate, it can prevent the sliding protrusion 104 from being separated from the mounting disk 100 and making it impossible to disinfect the catheter connector.

[0062] For example, reference Figure 2 A protrusion 110 is also provided on the mounting plate 100. When a plurality of clamping members 200 are arranged to enclose a disinfection space 208, the protrusion 110 is located in the disinfection space 208, and the disinfection cotton sheet covers the protrusion 110. When the catheter connector is inserted into the disinfection space 208, the protrusion 110 can extend into the interior of the catheter connector to disinfect the inner wall of the catheter connector, thereby enhancing the disinfection effect of the catheter connector and further reducing safety hazards.

[0063] In some implementations of the embodiments of the present application, reference is made to Figure 3 The sliding groove 301 has a limiting surface 302, which is located inside the sleeve 300 and is perpendicular to the extending direction of the sliding groove 301. When the sleeve 300 slides toward the free end 207 of the clamp 200, the sliding protrusion 104 slides into the sleeve 300 in the sliding groove 301 until the sliding protrusion 104 contacts the limiting surface 302. The sliding protrusion 104 can limit the limiting surface 302 to prevent the sleeve 300 from falling off from the free end 207 of the clamp 200 during the sliding process.

[0064] In some other implementations of the embodiments of the present application, reference is made to Figure 4 A fixing rod 500 is connected to the side of the mounting plate 100 away from the disinfection space 208, the sleeve 300 is sleeved on the outside of the fixing rod 500, and a stop plate 600 is provided at the end of the fixing rod 500 away from the mounting plate 100. The stop plate 600 is used to prevent the sleeve 300 from falling off from the end of the fixing rod 500 away from the mounting plate 100.

[0065] Exemplarily, the fixing rod 500 may include a plurality of support rods 501 and a plurality of connection plates 502, and the plurality of connection plates 502 are arranged in parallel and at intervals. A plurality of support rods 501 are connected between the connection plates 502 and the mounting plate 100, between adjacent connection plates 502, and between the connection plates 502 and the stop plate 600, and the plurality of support rods 501 are evenly arranged around the center line of the mounting plate 100. Such an arrangement can reduce the weight of the fixing rod 500 and ensure the strength of the fixing rod 500.

[0066] Exemplarily, the outer diameter of the stop plate 600 is larger than the inner diameter of the sleeve 300, so that when the sleeve 300 moves outside the fixing rod 500, the stop plate 600 can contact the wall of the sleeve 300 to limit the sleeve 300 and prevent the sleeve 300 from falling off from the end of the fixing rod 500 that is away from the mounting plate 100 during sliding.

[0067] In the process of sliding the sleeve 300 to the first position or the second position, the sleeve 300 can also be held to pull or push the stop plate 600, so that the mounting plate 100 can slide relative to the sleeve 300, thereby making the free ends 207 of the plurality of clamping members 200 approach or move away from each other. For example, the edge of the stop plate 600 can also be provided with an anti-slip protrusion 601 to facilitate pushing and pulling the stop plate 600.

[0068] For example, reference Figure 4 and Figure 5 , a plurality of first grooves 101 are provided on the edge of the mounting plate 100. The fixed end 201 of each clamping member 200 has a connecting portion 202, and each connecting portion 202 is inserted into the corresponding first groove 101. A rotating shaft 103 is provided on the groove wall of the first groove 101. A rotating hole 203 is provided on the connecting portion 202, and the rotating shaft 103 is penetrated in the rotating hole 203. The connecting portion 202 can rotate relative to the mounting plate 100 through the rotating hole 203 and the rotating shaft 103, so that each clamping member 200 can rotate relative to the mounting plate 100, so that the free ends 207 of each clamping member 200 can approach or move away from each other.

[0069] Both ends of the rotating shaft 103 may be directly connected to the groove wall of the first groove 101 . For example, both ends of the rotating shaft 103 may be directly connected to the groove wall of the first groove 101 by gluing or welding.

[0070] Exemplarily, the first groove 101 penetrates the mounting disk 101 along the axial direction of the mounting disk 101, and the groove wall of the first groove 101 may also be provided with a first through hole 102 perpendicular to the center line of the mounting disk 101, the first through hole 102 penetrates the mounting disk 100, the connecting portion 202 is inserted in the first groove 101, and the rotating hole 203 is opposite to the first through hole 102. The rotating shaft 103 is penetrated in the first through hole 102 and the rotating hole 203, and both ends of the rotating shaft 103 are located in the first through hole 102 and connected to the mounting disk 100.

[0071] In some implementations of the embodiments of the present application, reference is made to Figure 5 The catheter connector disinfection device further comprises an elastic member 400, wherein the elastic member 400 is multiple, and each elastic member 400 is connected to a clamping member 200 and a mounting plate 100. The elastic member 400 is used to drive the corresponding clamping member 200 to rotate in a direction in which the free end 207 is away from the center line of the mounting plate 100. When the sleeve 300 slides to the first position, the clamping member 200 rotates relative to the mounting plate 100, and the free ends 207 of the clamping member 200 approach each other, and at this time, the elastic member 400 is deformed; when the sleeve 300 moves to the second position, the elastic member 400 applies a restoring force to the clamping member 200 to drive the clamping member 200 to rotate in a direction in which the free end 207 is away from the center line of the mounting plate 100, so that the clamping member 200 can be automatically unfolded to remove the catheter connector and facilitate the placement of a new disinfection cotton pad.

[0072] For example, reference Figure 5 , the elastic member 400 may include a coil spring. A second groove 106 is provided on the side of the mounting plate 100 away from the sterilization space 208, and the second groove 106 is located on the side of the first groove 101 facing the center line of the mounting plate 100, and the second groove 106 is connected to the first groove 101; a third groove 204 corresponding to the second groove 106 is provided on the connecting portion 202; and the coil spring is accommodated in the second groove 106 and the third groove 204. In the process of the sleeve 300 pushing the clamping member 200 to rotate relative to the mounting plate 100, the coil spring can be accommodated in the second groove 106 and the third groove 204 to avoid interference with the sleeve 300.

[0073] refer to Figure 5The mounting plate 100 may be provided with a first connecting groove 108, the first connecting groove 108 being perpendicular to the second groove 106, a first connecting shaft 107 being provided in the first connecting groove 108, the first connecting shaft 107 being provided along the extension direction of the second groove 106, one end of the first connecting shaft 107 being connected to the groove bottom of the first connecting groove 108 through a connecting bolt 109, the other end of the first connecting shaft 107 being connected to the groove bottom of the first connecting groove 108 through another connecting bolt 109, and a connecting head of the coil spring being sleeved on the first connecting shaft 107. A second through hole 205 is provided on the groove wall of each third groove 204, a second connecting shaft 206 being penetrated in the second through hole 205, and another connecting head of the coil spring being sleeved on the second connecting shaft 206.

[0074] For example, reference Figure 6 The clamping member 200 may also be provided with a buffer pad 211 for contacting with the disinfection cotton pad, and the end of the buffer pad 211 away from the mounting plate 100 is connected to the clamping member 200 through a fixing portion 212. The buffer pad 211 has a buffering effect, which can prevent the catheter joint from colliding with the clamping member 200 to protect the catheter joint. The buffer pad 211 can increase the friction between the disinfection cotton pad and the disinfection cotton pad, thereby preventing the disinfection cotton pad from shifting during the wiping and disinfection process, thereby enhancing the disinfection effect on the catheter joint.

[0075] The shape of the buffer pad 211 can be set to an arc shape. When the sleeve 300 is located in the second position, the free ends 207 of the plurality of clamping members 200 are close to each other, and the plurality of buffer pads 211 can be arranged to form a cylindrical disinfection space 208, which can increase the contact area with the disinfection cotton pad, thereby increasing the contact area between the disinfection cotton pad and the catheter joint, thereby improving the uniformity of disinfecting the catheter joint. Exemplarily, the inner diameter of the cylindrical disinfection space 208 can be smaller than the maximum outer diameter of the catheter joint, so that the catheter joint is placed in the disinfection space 208 and is clamped and contacted by the buffer pad 211, thereby enhancing the disinfection effect of the disinfection cotton pad on the catheter joint. The surface of the buffer pad 211 in contact with the disinfection cotton pad can be a smooth surface to facilitate the cleaning of the buffer pad 211.

[0076] The fixing portion 212 of the buffer pad 211 may be bonded to the clamping member 200. Figure 6 A second connecting groove 209 may also be provided on the clamping member 200 , and the second connecting groove 209 is provided along the extension direction of the clamping member. The fixing portion 212 has a long strip protrusion, and the long strip protrusion is located in the second connecting groove 209 , and the long strip protrusion is connected to the clamping member 200 .

[0077] refer to Figure 4A third through hole 210 may be further provided on the clamping member 200, and a threaded hole may be provided on the elongated protrusion. The clamping member 200 may also be connected to the elongated protrusion by connecting bolts passing through the third through hole 210 and the threaded hole to increase the connection strength between the fixing portion 212 and the clamping member 200.

[0078] In some implementations of the embodiments of the present application, the catheter connector disinfection device also includes a clamping piece 700, which is disposed on the free end 207. The clamping piece 700 is used to press the disinfection cotton sheet on the free end 207 to prevent the disinfection cotton sheet and the clamping piece 200 from shifting and reducing the contact area with the catheter connector during the process of the sleeve 300 driving the mounting plate 100 and the clamping piece 200 to rotate, thereby enhancing the effect of disinfecting the catheter connector.

[0079] refer to Figure 7 and Figure 8 , the pressing member 700 may be disposed on the fixing portion 212 .

[0084] The working process of the catheter connector disinfection device of the embodiment of the present application is as follows:

[0085] First, the sleeve 300 is in the second position, and the catheter connector disinfection device is in the following state: Figure 2 The state shown. The disinfection cotton sheet is placed on the buffer pad 211 of the clamping member 200, and the disinfection cotton sheet covers the protrusion 110, the upper surface of the mounting plate 100 and the buffer pad 211. The corner of the disinfection cotton sheet is located on the pressing groove 215 of the fixing portion 212, and the pressing member 700 is moved so that the protrusion 703 on the connecting rod 702 is clamped in the fixing groove 214 of the fixing surface 213. When the protrusion 703 and the fixing groove 214 are in contact with one end of the mounting plate 100, the pressing portion 701 presses the corner of the disinfection cotton sheet in the pressing groove 215.

[0086] Then, hold the outer side of the sleeve 300 and pull the stop plate 600. The stop plate 600 drives the support rod 501, the connecting plate 502 and the mounting plate 100 to slide relative to the sleeve 300 under the action of the sliding protrusion 104 and the sliding groove 301. The sleeve 300 pushes each clamping member 200, and each clamping member 200 rotates relative to the mounting plate 100. The free end of each clamping member 200 moves toward the center line of the mounting plate 100. When the sleeve 300 is in the first position, each clamping member 200 is accommodated in the sleeve 300, and each buffer gasket 211 is surrounded to form a disinfection space 208. The catheter joint disinfection device is in a state as shown in FIG. Figure 1 The sterilizing cotton sheet is contained in the sterilizing space 208 and covers the inner wall of the sterilizing space 208. At this time, the elastic member 400 is pulled when the clamping member 200 rotates, and the elastic member 400 is deformed.

[0087] Then, the catheter connector is inserted into the disinfection space 208, the disinfection cotton sheet contacts the side wall and end of the catheter connector, the protrusion 110 extends into the interior of the catheter connector, and the disinfection cotton sheet covering the protrusion 110 contacts the inner wall of the catheter connector. The stopper plate 600 or the sleeve 300 is rotated to drive the mounting plate 100, the plurality of clamping members 200 and the disinfection cotton sheet to rotate, or the catheter connector is rotated to wipe and disinfect the catheter connector.

[0088] After the disinfection is completed, the sleeve 300 is held and the stop plate 600 is pushed. The stop plate 600 pushes the support rod 501, the connecting plate 502 and the mounting plate 100 to slide relative to the sleeve 300 under the action of the sliding protrusion 104 and the sliding groove 301. The elastic member 400 applies a restoring force to the clamping member 200, driving the free end 207 of the clamping member 200 to move in a direction away from the center line of the mounting plate 100. When the sleeve 300 is in the second position, a plurality of clamping members 200 and a buffer pad 211 are unfolded, and the catheter joint is taken out. The pressing member 700 is moved, so that the protrusion 703 slides from the end of the fixed groove 214 that is connected to the sliding groove 216 into the sliding groove 216. At this time, the pressing portion 701 is separated from the fixed portion 212, and the corner of the disinfection cotton sheet is taken out.
