[0004] A brief overview of the present application is provided below in order to provide a basic understanding of certain aspects of the present application. It should be understood that this overview is not an exhaustive overview of the present application. It is not intended to identify the key or important parts of the present application, nor is it intended to limit the scope of the present application. Its purpose is merely to present certain concepts in a simplified form as a prelude to a more detailed description discussed later.

[0005] One aspect of an embodiment of the present application provides a catheter locator, which is suitable for positioning a catheter. The catheter is suitable for being introduced into a patient's body. The catheter locator comprises: a hand-holding portion, a resting portion and a housing portion. The hand-holding portion is configured to be held by a user so that the user can insert the catheter into the housing portion; the resting portion is configured to rest against the outside of the patient's body so that the catheter inserted into the housing portion by the user can be positioned outside the patient's body; wherein the housing portion is configured to accommodate catheters of different radial sizes.

[0007] Furthermore, the hand-holding portion, the abutting portion and the accommodating portion are integrally formed.

[0008] Further, the accommodation portion is configured such that when the catheter is arranged in the accommodation portion, the catheter is covered by the accommodation portion.

[0009] Furthermore, the cross section of the accommodation portion is formed as a plurality of open circles with different radii.

[0010] Further, along the direction of placing the catheter into the receiving portion, the radii of the plurality of open circles are arranged to vary from large to small.

[0011] Furthermore, a plurality of adjusting portions are formed on an inner wall of one end of the accommodation portion close to the abutting portion to adjust the deviation of the size of the conduit and the accommodation portion.

[0012] Further, the adjusting portion is configured to extend from the inner wall of the accommodating portion toward the centers of a plurality of non-closed circles, and the adjusting portion is configured to have elasticity to allow the catheter to pass through.

[0013] Another aspect of an embodiment of the present application provides a catheter positioner assembly, which includes a plurality of the aforementioned catheter positioners; the plurality of catheter positioners are arranged such that a hand-held portion of a preceding catheter positioner is connected to an abutting portion of a succeeding catheter positioner.

[0014] Further, the hand-held portion and the abutting portion of the mutually connected catheter positioner are respectively provided with matching structures to enable the hand-held portion and the abutting portion to be matched and connected.

[0015] Furthermore, the matching structure is that one of the hand-holding part or the abutting part is formed with a protrusion, and the other one is formed with a groove, and the protrusion is matched and connected with the groove.

[0016] Furthermore, the matching structure forms magnetic attraction structures for the hand-held portion and the abutting portion respectively.

[0017] The catheter positioner provided in the embodiment of the present application is configured to allow a user to insert a catheter into the accommodating portion by holding the hand-held portion, and to enable the abutting portion to abut against the patient's body surface, so that the catheter accommodated therein can be fixed by abutting against the patient's body surface during puncture, thereby preventing repeated punctures caused by the catheter moving or falling off in the accommodating portion; the accommodating portion is configured to accommodate catheters of different radial sizes, so that when the catheter sizes required for puncture are different, there is no need to replace the catheter positioner, thereby saving the cost required to produce catheter positioners of different sizes.

[0018] The catheter locator assembly provided in the embodiment of the present application can extend the length range of the catheter being fixed by arranging the aforementioned multiple catheter locators to connect the hand-held part with the abutment part, thereby further preventing the catheter from being displaced or falling off; at the same time, arranging the catheter locator assembly to connect multiple catheter locators can improve the flexibility of catheter fixation, facilitate the disassembly of a single catheter locator, and also avoid extending a single catheter locator too long so that the catheter cannot extend out of the catheter locator, thereby facilitating the insertion of the catheter into the catheter locator.

[0027] Exemplary embodiments of the present application will be described below in conjunction with the accompanying drawings. For the sake of clarity and conciseness, not all features of the actual implementation are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary from implementation to implementation. In addition, it should be understood that although the development work may be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of this application.

[0028] It is also necessary to explain here that, in order to avoid obscuring the present application due to unnecessary details, only the device structure and / or processing steps closely related to the scheme according to the present application are shown in the accompanying drawings, while other details that are not very relevant to the present application are omitted.

[0029] The disclosure below provides a plurality of different embodiments or examples to implement the present application. In order to simplify the disclosure of the present application, the parts and methods of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the present application. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.

[0030] During venipuncture, setting a catheter locator can ensure that the catheter is accurately and stably placed in the vein, thereby avoiding displacement or detachment of the catheter, reducing the pain and inconvenience caused to the patient by repeated punctures, and at the same time, the catheter locator can also help medical staff better manage venous access, improve nursing efficiency and quality, and reduce the risk of complications. However, the catheter locator in the related art can only be used for one type of catheter, but not for multiple different types of catheters. In addition, the connection between multiple catheter locators is not convenient, and the reliability of the connection does not meet actual needs.

[0031] One aspect of an embodiment of the present application provides a catheter positioner, which is suitable for positioning a catheter, wherein the catheter is suitable for being introduced into a patient's body. Figure 2 A perspective schematic diagram showing a catheter positioner provided by an embodiment of the present application is shown. In some embodiments, as Figure 2 As shown, the catheter positioner of the present application includes: a hand-held portion 10, a rest portion 20 and a receiving portion 30, wherein the hand-held portion 10 is configured to be held by a user so that the user can insert a catheter into the receiving portion 30; the rest portion 20 is configured to rest against the outside of the patient's body so that the catheter inserted into the receiving portion 30 by the user can be positioned outside the patient's body; wherein the receiving portion 30 is configured to accommodate catheters of different radial sizes.

[0032] The catheter locator 100 provided in the embodiment of the present application is configured to allow a user to insert a catheter into the accommodating portion 30 by holding the hand-held portion 10, and to enable the abutting portion 20 to abut against the patient's body surface, so that the catheter accommodated therein can be fixed by abutting against the patient's body surface during puncture, thereby preventing repeated punctures caused by the catheter moving or falling off in the accommodating portion 30; the accommodating portion 30 is configured to accommodate catheters of different radial sizes, so that there is no need to replace the catheter locator when the catheter size required for puncture is different, thereby increasing the use of the catheter locator. In addition, the user does not need to replace the catheter locator due to changes in the catheter size during use. Therefore, there is no need to replace the catheter locator when positioning catheters of different sizes is required, thereby improving the efficiency of the operation.

[0033] In some embodiments, Figure 2 As shown, the receiving portion 30 is provided to extend between the grip portion 10 and the abutting portion 20 .

[0034] In some embodiments, the accommodating portion 30 extends between the hand-held portion 10 and the abutting portion 20 to form a predetermined extension length, so that the accommodating portion 30 has a predetermined space for accommodating the catheter. The accommodating portion 30 can be configured to form openings at both ends connected to the hand-held portion 10 and the abutting portion 20, so that the catheter can pass through the accommodating portion 30, and the hand-held portion is configured so that its extension direction is perpendicular to the extension direction of the accommodating portion 30, and is opposite to the direction of the opening of the accommodating portion 30 for the catheter to pass through, so as to avoid blocking the catheter from passing through the opening of the accommodating portion 30.

[0035] In some embodiments, the hand-held portion 10 , the abutting portion 20 , and the receiving portion 30 may be integrally formed.

[0036] In some embodiments, integrally molding the hand-held portion 10, the abutting portion 20, and the receiving portion 30 can avoid separate processing thereof, saving manufacturing steps. Meanwhile, the one-piece molding design can avoid disassembly connection between the hand-held portion 10 and the receiving portion 30 or between the abutting portion 20 and the receiving portion 30, thereby preventing possible looseness at any of them from affecting the use of the catheter locator 100 and improving the stability of the catheter locator 100.

[0037] Figure 1 A perspective schematic diagram of a catheter positioner provided by an embodiment of the present application is shown at an angle. In some embodiments, as Figure 1 As shown, the accommodation portion 30 is configured such that when the catheter is disposed in the accommodation portion 30 , the catheter is covered by the accommodation portion 30 .

[0038] In some embodiments, Figure 1 As shown, the accommodating portion 30 can be configured as an open groove-like structure. While forming an accommodating space for accommodating the catheter, the open groove-like structure helps the catheter to be smoothly inserted into the accommodating portion 30. If the accommodating portion is configured as a tubular structure with closed side walls, the friction between the closed side walls of the accommodating portion 30 and the catheter will be too large, which will hinder the catheter from being inserted therein.

[0039] In some embodiments, the accommodating space formed inside the accommodating portion 30 can be set to a cylindrical shape that matches the shape of the catheter, and the diameter of the cylindrical accommodating space can be set to a size that matches the outer diameter of the catheter, so that the catheter can be tightly covered by the accommodating portion after being inserted into the accommodating portion 30, preventing the catheter from being displaced in any direction within the accommodating space, thereby achieving the effect of positioning the catheter.

[0040] Figure 3 A schematic cross-sectional view of a receiving portion of a catheter positioner provided by an embodiment of the present application is shown. In some embodiments, as Figure 3 As shown, the cross section of the receiving portion 30 is formed as a plurality of open circles with different radii.

[0041] In some embodiments, Figure 3 As shown, a first accommodating space 301, a second accommodating space 302 and a third accommodating space 303 are formed inside the accommodating portion 30, and the first accommodating space 301, the second accommodating space 302 and the third accommodating space 303 are arranged to be interconnected, and their cross-sections are all non-closed circles with different diameters to accommodate catheters of different diameters.

[0042] In some embodiments, Figure 3 As shown, along the direction of placing the catheter into the accommodating portion 30, the radius of the multiple open circles is set to change from large to small. That is, the catheter with a smaller diameter can be accommodated by the first accommodating space 301, the catheter with a larger diameter can be accommodated by the second accommodating space 302, and the catheter with the largest diameter can be accommodated by the third accommodating space 303.

[0043] In some embodiments, the catheter can be placed into the accommodating portion 30 along the open portion of the side wall of the accommodating portion 30 . The accommodating portion 30 can be made of an elastic and ductile material so that the catheter can be smoothly expanded and placed into the accommodating portion 30 .

[0044] In some embodiments, Figure 3 As shown, the diameter of the third accommodating space 303 is the largest, and the diameter of the first accommodating space is the smallest. The accommodating spaces of adjacent sizes are arranged to be adjacent and connected, and the third accommodating space 303 is arranged at the proximal end of the side wall opening of the accommodating portion 30, and the first accommodating space 301 is arranged at the distal end of the side wall opening of the accommodating portion 30. This arrangement makes it possible for a catheter with a large diameter to be directly placed in the third accommodating space that matches its size when it is placed in the accommodating portion 30 from the opening, and for a catheter with a smaller size to be placed in the accommodating portion 30 from the opening, the catheter can pass through the accommodating space that is larger than its size and be directly placed in the accommodating space with a smaller diameter that matches its size. In this way, the accommodating portion 30 can accommodate catheters of different sizes while also making the placement process of catheters of different sizes smoother.

[0045] In some embodiments, Figure 1-3 As shown, a plurality of adjusting portions 31 are formed on the inner wall of the accommodating portion 30 at one end close to the abutting portion 20. The adjusting portions 31 may be arranged to extend from the inner wall of the accommodating portion 30 toward the center of the first accommodating space 301, the second accommodating space 302, and the third accommodating space 303, and the adjusting portions 31 may be arranged to be a plurality of flexible leaves with elasticity that allow the conduit to pass through each accommodating space, and the flexible leaves may be distributed radially.

[0046] By providing an adjusting portion 31 on the inner wall of one end of the accommodating portion 30 close to the abutting portion 20, a certain frictional resistance can be provided in the process of placing the catheter into the accommodating portion 30 from one end of the abutting portion 20. The adjusting portion 31 extends in a direction away from the abutting portion 20 as the catheter is inserted, and occupies a certain space in the accommodating space formed by the accommodating portion 30. When the size of the catheter is slightly smaller than the inner diameter of the corresponding accommodating space, the adjusting portion 31 with elastic force can provide a predetermined resistance for the catheter inside the accommodating portion 30 to support and fix the catheter in the accommodating portion 30, adjust the deviation between the size of the catheter and the accommodating space, and prevent the catheter from moving in the accommodating portion 30 or even falling off from the accommodating portion 30 due to the size deviation. As a result, the catheter positioner provided by the present application can fix catheters of more sizes without the need to replace the catheter positioner due to changes in the catheter size, thereby expanding the use scenarios of the catheter positioner and improving the operational efficiency of fixing the catheter.

[0047] Figure 4 Schematic diagram of assembling multiple catheter positioners provided by embodiments of the present application. In some embodiments, Figure 1 and Figure 4 As shown, another aspect of the embodiment of the present application provides a catheter positioner assembly 200, which includes a plurality of the aforementioned catheter positioners 100; the plurality of catheter positioners 100 are arranged such that the handheld portion 10 of the preceding catheter positioner is connected to the abutment portion 20 of the following catheter positioner.

[0048] The catheter locator assembly 200 provided in the embodiment of the present application can extend the length range of the catheter being fixed by configuring the aforementioned multiple catheter locators to connect the hand-held portion 10 with the abutment portion 20, thereby further preventing the catheter from being displaced or falling off; at the same time, configuring the catheter locator assembly 200 to connect multiple catheter locators 100 can improve the flexibility of catheter fixation, facilitate the disassembly of a single catheter locator 100, and also prevent a single catheter locator 100 from extending too long so that the catheter cannot extend out of the catheter locator 100, thereby facilitating the insertion of the catheter into the catheter locator 100.

[0049] In some embodiments, the handheld portion 10 and the abutting portion 20 of the mutually connected catheter positioner are respectively provided with matching structures to enable the handheld portion 10 and the abutting portion 20 to be matched and connected.

[0050] In some embodiments, Figure 4 As shown, the hand-held portion and the abutment portion 20 of the interconnected catheter positioners are connected along the extension direction of the accommodating portion 30 so that the accommodating portions 30 of the interconnected catheter positioners are connected on the same straight line to avoid bending of the catheter in the accommodating portion 30 due to misalignment.

[0051] In some embodiments, the matching structure may be that one of the hand-held portion 10 or the abutting portion 20 is formed with a protrusion, and the other is formed with a groove, and the protrusion is matched and connected with the groove.

[0052] In some embodiments, the interconnected catheter positioners can be plugged into each other through the protrusions and grooves formed at the joints so that the catheter positioners can be stably connected without the need for additional parts or media for reinforcement (e.g., bundling or bonding), making disassembly and removal after use more convenient.

[0053] In some embodiments, the matching structure may be a magnetic attraction structure formed by the hand-held portion 10 and the abutting portion 20 respectively.

[0054] In some embodiments, the interconnected catheter locators can also be magnetically connected via a magnetic structure formed at the joint, wherein the magnetic structure is configured to require a sufficiently large force to disconnect the hand-held portion 10 and the abutment portion 20, so that the catheter locator can be stably connected and does not require additional components or media for reinforcement (for example, bundling or bonding), making disassembly and removal after use more convenient.

[0055] In some embodiments, Figure 2 As shown, a protrusion 101 is formed on the hand-held portion 10 to increase the friction between the hand-held portion 10 and the hand, thereby preventing the catheter positioner 100 from falling off from the user's hand when placing the catheter.

[0056] The following describes how to use the catheter locator provided by the present application.

[0057] After the patient undergoes a puncture operation, in some cases the catheter cannot be withdrawn from the body and needs to be fixed at the puncture site to protect and support the blood vessels and prevent relative displacement between the catheter and the puncture site, thereby affecting the position of the catheter in the body, avoiding harm to the patient caused by catheter movement, and reducing vascular damage and complications.

[0058] The operator can hold the hand-held portion 10 to fix the catheter locator 100 in his hand, and place the catheter to be positioned into the accommodating portion 30 from the opening of the side wall of the accommodating portion 30, so that the catheter is fixed by the accommodating space of matching size to prevent the catheter from being displaced; after the catheter is placed, the abutment portion 20 of the catheter locator 100 abuts against the skin surface where the puncture port is located, acting as a stopper to further prevent the catheter in the accommodating portion 30 from moving.

[0059] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0060] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
