[0032] To solve the problems in the prior art, the present application provides a sterile protective sleeve. The structure of the sterile protective sleeve will be described below with reference to the drawings.

[0033] Figure 1 is a front view of the sterile protective sleeve provided by some embodiments of the present application, Figure 2 is an exploded view of the sterile protective sleeve and a target instrument provided by some embodiments of the present application, Figure 3 is an assembly view of the sterile protective sleeve and the target instrument provided by some embodiments of the present application.

[0034] Referring to Figures 1 to 3 The embodiments of the present application provide a sterile protective sleeve 100, which comprises a sleeve body 110 and a first connecting structure 120. The sleeve body 110 is provided with a containing cavity (not labeled in the figure) and a first opening K1 located on one side of the containing cavity along a first direction X. The first opening K1 is in communication with the containing cavity, and at least part of the sleeve body 110 is foldable along the first direction X or the reverse direction thereof. The first direction X is the length direction of the sleeve body 110. The first connecting structure 120 comprises a first connecting piece 122, which is arranged on one side of the sleeve body 110 close to the first opening K1 and connected with the sleeve body 110.

[0035] The sleeve body 110 is a component of the sterile protective sleeve 100 for wrapping the target instrument 200 so that the target instrument 200 is in an approximately sterile state. Specifically, the sleeve body 110 is provided with a cavity for accommodating at least part of the target instrument 200 and a first opening K1 communicating with the cavity for the target instrument 200 to enter the cavity. The target instrument 200 in the cavity can be separated from the external environment to reduce the risk of contamination of the target instrument 200.

[0036] At least part of the sleeve body 110 is foldable along the first direction X or the reverse direction thereof, i.e. the opposite direction of the first direction X. For example, at least part of the sleeve body 110 can be approximately corrugated. By applying force to the at least part of the sleeve body 110, the at least part of the sleeve body 110 can be stretched along the first direction X, and the size of the cavity along the first direction X can be increased accordingly. During the assembly of the sterile protective sleeve 100 and the target instrument 200, a part of the target instrument 200 can be inserted into the cavity through the first opening K1 when the sleeve body 110 is in a folded state, so that the sleeve body 110 wraps part of the target instrument 200. Then, the sleeve body 110 can be stretched along the first direction X, and the size of the cavity along the first direction X and the wrapping area of the sleeve body 110 on the target instrument 200 can be increased.

[0037] The first connecting structure 120 is used to connect the sleeve body 110 and the target instrument 200 after the target instrument 200 is inserted into the cavity, so as to reduce the risk of separation of the sleeve body 110 and the target instrument 200. The first connecting structure 120 includes a first connecting piece 122, which is a component of the first connecting structure 120 for connecting the sleeve body 110 and driving the sleeve body 110 to stretch along the first direction X. The first connecting piece 122 is used for the sleeve body 110 connection, which can serve as an operating component of the sleeve body 110 for an operator to drive the sleeve body 110 to stretch until the sleeve body 110 is wrapped around a predetermined part of the target instrument 200. The first connecting piece 122 can be connected to the sleeve body 110 in various ways, such as by adhesion or by thread suture, which is not limited in the present embodiment.

[0038] In addition, the first connecting piece 122 can also be used to connect the target instrument 200, which can be directly connected to the target instrument 200 or connected to the target instrument 200 by means of other structures. The first connecting piece 122 is arranged on one side of the sleeve body 110 close to the first opening K1, such as Figure 3As shown, when the target instrument 200 extends into the cavity through the first opening K1, the sleeve body 110 can extend to a preset position under the drive of the first connector 122. At this time, the first connector 122 can be connected to the target instrument 200 by means of other structures to fix the sleeve body 110 and the target instrument 200, thereby reducing the risk of the target instrument 200 separating from the sleeve body 110 from the first opening K1.

[0039] This application provides a sterile protective sleeve 100, including a sleeve body 110 and a first connecting structure 120. The sleeve body 110 has a cavity and a first opening K1 located on one side of the cavity along the first direction X. The first opening K1 communicates with the cavity. The sleeve body 110 is folded along the first direction X or its opposite direction, so that the operator does not need to repeatedly fold the sleeve body 110, which can improve the assembly efficiency of the sterile protective sleeve 100 and reduce the risk of contamination of the sterile protective sleeve 100 during the assembly process, thereby improving the safety of diagnosis and treatment. A first connector 122 is provided on the side wall of the sleeve body 110 near the first opening K1 along the first direction X. The first connector 122 is connected to the sleeve body 110. Therefore, during the assembly process of the sterile protective sleeve 100 and the target instrument 200, the sleeve body 110 can be extended along the first direction X by means of the first connector 122 to increase the coverage area of ​​the sleeve body 110 on the target instrument 200, so as to achieve sterile isolation of the sterile protective sleeve 100 on the target instrument 200. At the same time, it can also reduce the contact between the operator and the sleeve body 110, and further reduce the risk of contamination of the sterile protective sleeve 100 during the assembly process.

[0040] It should be noted that the sterile protective sleeve 100 provided in this embodiment can be a structure with one open end, including a first opening K1. In this case, the target device 200 can be a medical device such as an ultrasound probe or endoscope, and the sterile protective sleeve 100 can be used to sterilely isolate the ultrasound probe, endoscope, or other such device. Alternatively, the sterile protective sleeve 100 can also be a structure with two open ends, including a first opening K1 and a second opening. In this case, the sterile protective sleeve 100 can be used to sterilely isolate the target device 200 and the sterile diagnostic and therapeutic device 300 during the connection process. The target device 200 and the sterile diagnostic and therapeutic device 300 can be any device used in conjunction during the diagnosis and treatment process. For example, the sterile diagnostic and therapeutic device 300 can be a connecting handle with an integrated conductive cable in a ventricular assist device, and the target device 200 can be a matching handle electrically connected to the terminal device. After the target device 200 and the sterile diagnostic and therapeutic device 300 are connected inside the sterile protective sleeve 100, the electrical connection between the terminal device and the ventricular assist device can be finally realized.

[0041] In some embodiments, the first connection structure 120 further includes a second connector 121, which is connected to the target instrument 200 and can cooperate with and connect to the first connector 122.

[0042] The second connector 121 is a component in the first connection structure 120 used to connect with the target device 200. There are various ways to connect the second connector 121 to the target device 200, such as by adhesive bonding or snap-fitting. Optionally, the target device 200 may include a device body and a wire connected to the device body. The second connector 121 can be connected to either the device body or the wire.

[0043] There are several ways to connect the second connector 121 and the first connector 122. For example, a portion of the first connector 122 can pass approximately along the first direction X through the second connector 121 and extend to connect with another portion of the first connector 122. In this case, the first connector 122 can limit the position of the sleeve body 110 and the second connector 121 along the first direction X, thereby fixing the position of the sleeve body 110 and the target instrument 200. Alternatively, the second connector 121 and the first connector 122 can also be connected by snap-fitting, adhesive bonding, or other methods. This embodiment does not impose any restrictions on this.

[0044] In these embodiments, the second connector 121 is connected to the target device 200, and the second connector 121 can cooperate and connect with the first connector 122. That is, the sleeve body 110 can be connected to the target device 200 through the cooperation of the first connector 122 and the second connector 121 to fix the sleeve body 110 and the target device 200, reducing the risk of the target device 200 separating from the sleeve body 110 from the first opening K1. Furthermore, the first connector 122 is connected to the target device 200 by means of the second connector 121, which reduces the connection difficulty and improves the operation efficiency compared to directly connecting the first connector 122 to the target device 200.

[0045] Please continue reading. Figure 2 In some embodiments, the first connector 122 includes a fixed part 1221 and a movable part 1222. The fixed part 1221 is connected to the sleeve body 110. A part of the movable part 1222 is connected to the fixed part 1221, and the other part cooperates with the second connector 121 to realize the connection between the second connector 121 and the first connector 122.

[0046] The fixing component 1221 is a component used to connect the sleeve body 110 and the movable component 1222. There are various ways to connect the fixing component 1221 to the sleeve body 110. For example, the fixing component 1221 can be connected to the sleeve body 110 by means of bonding, heat pressing, etc.

[0047] The movable component 1222 is a component that can move relative to the sleeve body 110. The movable component 1222 can be a strip-shaped structure or a bar-shaped structure, with one end connected to the fixed component 1221. Therefore, during the assembly process of the sterile protective sleeve 100 and the target instrument 200, the operator can use the movable component 1222 to extend the sleeve body 110 along the first direction X, thereby reducing the contact between the operator and the sleeve body 110. Furthermore, the end of the movable component 1222 away from the fixed component 1221 can cooperate with the second connecting member 121 to connect the second connecting member 121 to the first connecting member 122, that is, to fix the position of the sleeve body 110 and the target instrument 200 along the first direction X.

[0048] There are multiple ways in which the movable part 1222 can be connected to the second connector 121. For example, the end of the movable part 1222 away from the fixed part 1221 can pass through the second connector 121, and after passing through the second connector 121, it can wrap around back to connect with the fixed part 1221, thereby realizing the mutual connection between the second connector 121 and the first connector 122. On the one hand, this can improve the connection reliability between the second connector 121 and the first connector 122. On the other hand, by adjusting the actual position of the end of the movable part 1222 away from the fixed part 1221 connected to the fixed part 1221, the distance between the fixed part 1221 and the second connector 121 in the first direction X can also be adjusted, that is, the relative position of the sleeve body 110 and the target instrument 200 in the first direction X can be adjusted, so as to improve the flexibility of the sterile protective sleeve 100 during use. Alternatively, the movable part 1222 can also be connected to the second connector 121 by other means such as bonding or snap-fitting. As long as the connection between the movable part 1222 and the second connector 121 can be achieved, the specific connection method is not limited in this embodiment.

[0049] There are various ways to connect the movable part 1222 and the fixed part 1221. For example, the movable part 1222 and the fixed part 1221 can be connected by adhesive. The adhesive method is not limited to using glue; it can be similar to Velcro. For example, one of the fixed part 1221 and the movable part 1222 can have a barbed surface, while the other has a rough surface. The movable part 1222 and the fixed part 1221 are connected by the mutual adhesion of the barbed and rough surfaces. Of course, the movable part 1222 and the fixed part 1221 can also be connected by snap-fit ​​or other methods; this embodiment does not limit this.

[0050] In some embodiments, the movable part 1222 is detachably connected to the second connector 121 to facilitate the assembly and disassembly of the first connector 122 and the second connector 121, thereby enabling the connection and separation of the sterile protective sleeve 100 and the target instrument 200, which helps to improve operational efficiency and save operation time.

[0051] It should be noted that the movable part 1222 can be detachably connected to the second connector 121 by the above-mentioned method of passing through the second connector 121 and looping back to connect with the fixed part 1221, or it can be detachably connected to the second connector 121 by other methods such as snap-fit. This embodiment does not limit this.

[0052] Figure 4 This is another front view of the sterile protective sleeve provided in some embodiments of this application.

[0053] Please see Figure 4 In some embodiments, the fixing member 1221 and the sleeve body 110 are arranged along the second direction Y. The fixing member 1221 includes a first contact surface S1 facing away from the sleeve body 110 along the second direction Y. The movable member 1222 includes a second contact surface S2. After the end of the movable member 1222 away from the fixing member 1221 passes through the second connector 121, at least a portion of the second contact surface S2 is attached to and bonded to the first contact surface S1. The second direction Y is perpendicular to the first direction X.

[0054] The second direction Y can be either the width or height direction of the sleeve body 110. The fixing member 1221 is disposed on one side of the sleeve body 110 along the second direction Y, and its surface away from the sleeve body 110 along the second direction Y is the first contact surface S1. It is understood that the first contact surface S1 can be the entire surface of the fixing member 1221 away from the sleeve body 110 along the second direction Y, or it can be a portion of the surface of the fixing member 1221 away from the sleeve body 110 along the second direction Y; this embodiment does not impose any limitations on this.

[0055] The movable component 1222 includes a second facing surface S2. The second facing surface S2 can be located on the side of the movable component 1222 away from the sleeve body 110 along the second direction Y. It can be connected to the first facing surface S1 or spaced apart from the first facing surface S1. When the end of the movable component 1222 away from the fixed component 1221 passes through the second connector 121, at least a portion of the second facing surface S2 can be attached and bonded to the first facing surface S1 to achieve mutual connection between the second connector 121 and the first connector 122, which can further reduce the connection difficulty between the second connector 121 and the first connector 122.

[0056] It should be noted that the first surface S1 and the second surface S2 can be bonded together using adhesive. Alternatively, the first surface S1 and the second surface S2 can also be bonded together in a manner similar to Velcro. For example, one of the first surface S1 and the second surface S2 can be a barbed surface, while the other is a rough surface. The barbed surface and the rough surface can be bonded together after being pressed together. In this case, the fixed part 1221 and the movable part 1222 can be repeatedly bonded and separated using the first surface S1 and the second surface S2 to facilitate the transfer of the instrument.

[0057] It should be noted that the second connector 121 may be provided with a through hole for the movable part 1222 to pass through. The movable part 1222 may pass through the second connector 121 approximately along the first direction X, or it may pass through the second connector 121 in other directions. This embodiment does not limit this.

[0058] Optionally, the sleeve body 110 can be a flexible structure, such as a plastic film structure. When the movable parts 1222 of the multiple first connectors 122 pass through the second connectors 121 on the target instrument 200 and rewind to connect with the fixed parts 1221, the part of the sleeve body 110 near the first opening K1 can deform under the action of the multiple first connectors 122 to tighten the first opening K1 to a certain extent and improve the aseptic isolation effect of the sleeve body 110 on the part of the target instrument 200 located in the cavity.

[0059] Figure 5 This is a schematic diagram of the structure of the second connector in the sterile protective sleeve provided in some embodiments of this application.

[0060] Please see Figure 5 In some embodiments, the second connector 121 is provided with a locking hole 1211, and the side wall corresponding to the locking hole 1211 is provided with a notch 1212 that extends along the first direction X. The radial dimension of the locking hole 1211 is larger than the radial dimension of the target instrument 200.

[0061] The shape of the locking hole 1211 can be adapted to the shape of the pre-connection position on the target instrument 200. Its radial dimension can be smaller than the radial dimension of the pre-connection position of the target instrument 200. For example, when the cross-sectional shape of the pre-connection position is circular, the locking hole 1211 is a circular hole, and its diameter can be smaller than the outer diameter of the pre-connection position of the target instrument 200. Therefore, the second connector 121 can be locked by interference fit with the pre-connection position of the target instrument 200 through the locking hole 1211.

[0062] A notch 1212 is formed on the sidewall of the second connector 121 corresponding to the locking hole 1211. The notch 1212 penetrates the second connector 121 along the first direction X and can communicate with the locking hole 1211. That is, the notch 1212 can extend from the inner wall of the locking hole 1211 to the outer edge of the second connector 121, so that the target instrument 200 can enter the locking hole 1211 through the notch 1212. In the radial direction of the locking hole 1211, the width of the notch 1212 can be smaller than the radial dimension of the locking hole 1211. When the locking hole 1211 is a circular hole, the width of the notch 1212 can be smaller than the diameter of the locking hole 1211. Therefore, the risk of the target instrument 200 getting stuck in the locking hole 1211 and then coming out of the second connector 121 through the notch 1212 can be reduced, and the connection reliability between the second connector 121 and the target component can be improved.

[0063] It should be noted that the radial direction mentioned in this embodiment refers to the radial direction of the locking hole 1211 when the locking hole 1211 is a circular hole, or it can refer to one of the directions in the plane perpendicular to the first direction X.

[0064] Please continue reading. Figure 2 and Figure 3 In some embodiments, there are multiple first connectors 122, and the multiple first connectors 122 are arranged circumferentially along the body 110.

[0065] The number of first connectors 122 can be flexibly set according to the size and shape of the second opening, target instrument 200, and second connectors 121 in practical applications. Multiple first connectors 122 are arranged circumferentially along the sleeve body 110. When the movable part 1222 of the first connector 122 passes through the second connector 121 and then loops back to connect with its fixed part 1221, the second connector 121 can have multiple through holes along the circumferential direction of the sleeve body 110 for the movable parts 1222 of the multiple first connectors 122 to pass through.

[0066] In these embodiments, a plurality of first connectors 122 are arranged circumferentially along the sleeve body 110. The plurality of first connectors 122 can be connected to second connectors 121 circumferentially along the sleeve body 110, which can improve the connection reliability between the sleeve body 110 and the second connectors 121, that is, improve the connection reliability between the sleeve body 110 and the target instrument 200.

[0067] Please continue reading. Figure 1 and Figure 2 In some embodiments, the sleeve body 110 includes a folding portion 111 and a first flattening portion 112 arranged sequentially along the first direction X, a first opening K1 is formed in the first flattening portion 112, and a first connector 122 is connected to the first flattening portion 112.

[0068] The folding part 111 is the part of the sleeve body 110 that is folded along the first direction X. The first flat part 112 is the part of the sleeve body 110 that is not folded along the first direction X. Compared with the folding part 111, the first flat part 112 is in a relatively flat state. The folding part 111 and the first flat part 112 are connected sequentially along the first direction X, that is, the first flat part 112 is located on the side of the folding part 111 along the first direction X.

[0069] In these embodiments, by providing the sleeve body 110 to include a first flat portion 112, such that the first opening K1 is formed on the first flat portion 112, and the first connector 122 is connected to the first flat portion 112, the difficulty of forming the first opening K1 and the difficulty of connecting the first connector 122 to the sleeve body 110 can be reduced compared to forming the first opening K1 on the fold portion 111 and connecting the first connector 122 to the fold portion 111.

[0070] Figure 6 This is a front view of a sterile protective sleeve provided in other embodiments of this application. Figure 7 This is an exploded view of the sterile protective sleeve and target device 200 provided in other embodiments of this application.

[0071] Please see Figure 6 and Figure 7 In some embodiments, the sleeve body 110 is provided with a second opening (not shown in the figure) on the side away from the first opening K1 along the first direction X. The sterile protective sleeve 100 also includes a second connecting structure 130 disposed on the side of the sleeve body 110 near the second opening. The second connecting structure 130 is used to close the second opening.

[0072] The first opening K1 and the second opening are located on opposite sides of the sleeve body 110 along the first direction X. The second opening allows the sterile medical instrument 300 to pass through and enter the cavity, enabling the sterile medical instrument 300 and the target instrument 200 to be connected within the cavity. The second connecting structure 130 is used to close the second opening. The specific structure of the second connecting structure 130 can be various; for example, the second connecting structure 130 can be a strip structure with Velcro, or it can be a fixing strap structure with push-button buckles. This embodiment does not limit this.

[0073] In these embodiments, the sleeve body 110 is provided with a second opening on the side away from the first opening K1 along the first direction X. This allows the sterile protective sleeve 100 to be used for sterile isolation between the target device 200 and the sterile diagnostic and therapeutic device 300 during the connection process, thereby expanding the application range of the sterile protective sleeve 100. Furthermore, a second connecting structure 130 is provided to close the second opening after the sterile diagnostic and therapeutic device 300 is inserted into the cavity. This improves the connection reliability between the sleeve body 110 and the sterile diagnostic and therapeutic device 300 and reduces the risk of the sterile diagnostic and therapeutic device 300 detaching from the sleeve body 110 through the second opening.

[0074] Please continue reading. Figure 6 In some embodiments, the second connecting structure 130 is connected to the outer periphery of the sleeve body 110 and includes a fourth adhesive surface S4 and a fifth adhesive surface disposed opposite to each other. The fourth adhesive surface S4 and the fifth adhesive surface are used to adhere and bond to each other after the second connecting structure 130 extends around the sleeve body 110 in a circumferential direction, which can reduce the difficulty of operation when closing the second opening through the second connecting structure 130.

[0075] The fourth and fifth facing surfaces are located on opposite sides of the second connecting structure 130. When the second connecting structure 130 extends circumferentially around the sleeve body 110, a portion of the fourth facing surface S4 and a portion of the fifth facing surface can overlap and adhere to each other, thereby achieving adhesion. It should be noted that the fourth and fifth facing surfaces S4 and S5 can be adhered using adhesive. Alternatively, the fourth and fifth facing surfaces S4 and S5 can be adhered using a method similar to Velcro. For example, one of the fourth and fifth facing surfaces S4 can be a barbed surface, and the other a rough surface; the barbed and rough surfaces can adhere to each other after being adhered together.

[0076] like Figure 6 and Figure 7 As shown, the second connecting structure 130 is disposed on the outer periphery of the sleeve body 110. When the second connecting structure 130 extends around the sleeve body 110 in the circumferential direction, by adjusting the circumference of the second connecting structure 130 in the circumferential direction of the sleeve body 110, the corresponding sleeve body 110 can be deformed under the action of the second connecting structure 130. The part of the sleeve body 110 that is deformed can fit against the outer wall of the sterile diagnostic and therapeutic instrument 300 inserted into the cavity, thereby achieving the closing of the second opening.

[0077] Figure 8 This is a side view of the sterile protective sleeve provided in some embodiments of this application in a folded state.

[0078] Please see Figure 8In some embodiments, the first connector 122 includes a fixed component 1221 and a movable component 1222 arranged sequentially. The fixed component 1221 is connected to the sleeve body 110. The movable component 1222 includes a second adhesive surface S2 and a third adhesive surface S3 arranged opposite to each other. The second adhesive surface S2 and the third adhesive surface S3 are used to adhere and bond to each other after the movable component 1222 passes through the cavity through the first opening K1 and the second opening.

[0079] When the sleeve body 110 is in a folded state, a portion of the movable part 1222 away from the fixed part 1221 can pass through the cavity from the fixed part 1221 through the first opening K1 and the second opening, and then extend towards the fixed part 1221. At this time, the portion of the movable part 1222 away from the fixed part 1221 and the portion of it near the fixed part 1221 can be attached and bonded to each other through the second adhesive surface S2 and the third adhesive surface S3, thereby limiting the sleeve body 110 in the folded state and reducing the risk of the sleeve body 110 extending in the first direction X at the edge of use.

[0080] It should be noted that the second surface S2 and the third surface S3 are located on opposite sides of the movable part 1222. Therefore, when a portion of the movable part 1222 moves away from the fixed part 1221 through the cavity and extends towards the fixed part 1221, a portion of the second surface S2 of the movable part 1222 can overlap and adhere to a portion of the third surface S3, thereby achieving adhesion. It should be noted that the second surface S2 and the third surface S3 can be adhered using adhesive. Alternatively, the second surface S2 and the third surface S3 can also be adhered in a manner similar to Velcro. For example, one of the second surface S2 and the third surface S3 can be a barbed surface, and the other a rough surface; the barbed and rough surfaces can adhere to each other after being adhered. When the second surface S2 of the movable part 1222 is bonded to the first surface S1 of the fixed part 1221 using adhesive, the second surface S2 and the third surface S3 of the movable part 1222 can also be bonded using adhesive; when the second surface S2 of the movable part 1222 is bonded to the first surface S1 of the fixed part 1221 in a manner similar to Velcro, the second surface S2 and the third surface S3 of the movable part 1222 can also be bonded in a manner similar to Velcro.

[0081] Please continue reading. Figure 6 In some embodiments, the sleeve body 110 includes a folded portion 111 and a second flattened portion 113 arranged sequentially along a first direction X, a second opening is formed in the second flattened portion 113, and a second connecting structure 130 is connected to the second flattened portion 113.

[0082] The second flattening portion 113 is the part of the sleeve body 110 that is not folded along the first direction X. Compared to the folded portion 111, the second flattening portion 113 is in a relatively flat state. The second flattening portion 113 is disposed on one side of the folded portion 111 along the first direction X. When the sleeve body 110 also includes the first flattening portion 112, the first flattening portion 112 and the second flattening portion 113 are respectively disposed on opposite sides of the folded portion 111 along the first direction X.

[0083] In these embodiments, by providing the sleeve body 110 to include a second flat portion 113, such that the second opening is formed in the second flat portion 113, and the second connecting structure 130 is connected to the second flat portion 113, the difficulty of forming the second opening and the difficulty of connecting the second connecting structure 130 to the sleeve body 110 can be reduced compared to forming the second opening in the fold portion 111 and connecting the second connecting structure 130 to the fold portion 111.

[0084] Optionally, after the second connecting structure 130 extends circumferentially around the sleeve body 110, the fourth adhesive surface S4 of the second connecting structure 130 faces the sleeve body 110, and the fifth adhesive surface faces away from the sleeve body 110. At this time, a sixth adhesive surface can be provided on the side of the second flat part 113 facing away from the cavity. The sixth adhesive surface can have the same adhesive structure as the fifth adhesive surface, and it can adhere and bond with the fourth adhesive surface S4 to further improve the bonding reliability of the second connecting structure 130.
