Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a dialysis catheter fixing device 100 according to an embodiment of the present disclosure. In this embodiment, the dialysis catheter fixing device 100 can include a main body. Illustratively, the body has opposing first and

second faces

110, 120. The left side of fig. 1 is a schematic view of the first surface 110, and the right side of fig. 1 is a schematic view of the second surface 120.

The first surface 110 may be provided with at least two groove structures 111 (e.g. two groove structures 111, or more, 3, 5, etc., which may be designed adaptively according to the actual application, and of course, there is a case where a plurality of conduits are disposed in one groove, which is not limited herein). Each groove structure 111 can be used for accommodating a dialysis catheter, wherein an external force with at least a first predetermined magnitude is required to cause relative displacement between the dialysis catheter accommodated in the groove structure 111 and the groove structure 111 (1-10N, such as 1N, 5N, 10N, etc., but can also be designed to resist a larger external force, such as 20N, which is not limited herein).

The second surface 120 may be provided with a connecting mechanism 121, the connecting mechanism 121 may include a first component 1211 and a second component 1212 which are engaged with each other, and the first component 1211 and the second component 1212 may be engaged with each other after being separated from the outside clothes, wherein an external force with at least a second preset value is required to separate the cloth from the first component 1211 and the second component 1212, and the external force is between 10 and 100N (for example, 10N, 50N, 100N, etc., but may also be designed to resist a larger external force, for example, 150N, which is not limited herein). The first component 1211 and the second component 1212 may be separate, connected, or integrated, and are not limited herein.

Thus, two dialysis catheters for dialysis of a patient can be respectively arranged in the two groove structures 111, and the first component 1211 and the second component 1212 are matched and connected after the clothes of the patient are dialyzed at intervals, so that the main body and the clothes are relatively fixed, and the dialysis catheters are fixed.

The main body has a first face 110 and a second face 120 opposite to each other, the first face 110 is provided with at least two groove structures 111, each groove structure 111 can accommodate one dialysis catheter, thus two main catheters can be accommodated. For the catheter installed in the groove structure 111, at least an external force with a first predetermined value (e.g., 1-10N) is required to displace the dialysis catheter installed in the groove structure 111 relative to the groove structure 111, so as to secure the fixing effect of the groove structure 111 on the catheter as much as possible. The second surface 120 is provided with a connecting mechanism 121 (including a first component 1211 and a second component 1212 which are engaged with each other), the first component 1211 and the second component 1212 are engaged with each other after being engaged with each other at the outside of the interval between the first component 1211 and the second component 1212 (i.e., the first component 1211 and the second component 1212 can be engaged with each other at the interval between the clothes, so as to fix the main body to the clothes of the patient), and for the main body connected to the clothes, at least an external force (e.g., 10-100N) with a second preset value is required to remove the cloth from contact with the first component 1211 and the second component 1212, so that the main body can be firmly fixed to the clothes of the patient. Then, two dialysis catheters for dialysis of a patient can be respectively arranged in the two groove structures 111, and the first component 1211 and the second component 1212 are matched and connected after the clothes of the patient are dialyzed at intervals, so that the main body and the clothes are relatively fixed, and the dialysis catheters are fixed. Such an approach is simple and effective, and due to the simple construction of the dialysis catheter fixing device 100, the material requirements are low, and it is possible to keep the costs very low, which is also a very suitable option for the patient, with little economic burden on the patient. In addition, the catheter can be fixed on clothes of a patient in such a way, so that excessive behavior limitations such as turning over and action amplitude do not exist in the dialysis period of the dialysis patient, and the experience of the patient in the dialysis period can be effectively improved. In addition, the dialysis catheter fixing device 100 can be manufactured and used as a disposable device, or can be manufactured and used according to a standard of repeated use, thereby further saving the cost.

In this embodiment, the groove structure 111 disposed on the first surface 110 may be: the groove structure 111 is disposed on the first surface 110 (for example, in the case shown in fig. 1), or an assembly having the groove structure 111 is disposed on the first surface 110 (for example, in the case shown in fig. 2, fig. 2 is a schematic structural view of a dialysis catheter fixing device 100 provided in an embodiment of the present application, in which the assembly having the groove structure 111 is disposed on the first surface 110, a left portion of fig. 2 is a schematic view of the first surface 110, and a right portion of fig. 2 is a schematic view of the second surface 120).

The groove structure 111 may be a groove formed on the first surface 110, or a combination of the groove structure 111 and the first surface 110, and these two ways can be selected as required. Because the main body and the groove structure 111 have different functions and requirements (the main body has certain hardness requirement to ensure quality, and the groove structure 111 only needs to limit the displacement of the catheter, and has lower requirement, so the two have different material requirements), if the cost is saved, the low-cost material can be selected to manufacture the component with the groove structure 111 and then be adhered to the first surface 110, the process is simple, the cost is controlled, the disposable dialysis catheter fixing device 100 is suitable for manufacturing, and the disposable dialysis catheter fixing device can be well applied to some occasions where the patient cannot be repeatedly used, for example, the patient has diseases with extremely strong infectivity. In order to ensure the quality, materials with certain hardness requirements can be selected, the material cost can be increased, but the materials can be used for multiple times at low cost.

For example, in the case that the first surface 110 is provided with the groove structure 111, referring to fig. 1, the dialysis catheter fixing device 100 may further include a constricting mechanism 130. The binding mechanism 130 may include an adjustment key 131 and a binding 132, and the adjustment key 131 may be disposed on the body and outside the groove of the groove structure 111. The tightening member 132 is disposed in the groove and connected to the adjustment key 131. The adjustment key 131 on the main body can be adjusted to drive the tightening member 132 to move, so as to change the distance between the tightening member 132 and the inner wall of the groove, thereby adjusting the tightness of the dialysis catheter arranged therein. For example, the adjusting key 131 is a threaded rod with a knob, the threaded rod is connected with the tightening member 132, and the adjusting knob can drive the threaded rod to rotate to adjust the screwing depth, so as to change the position of the tightening member 132, and change the distance between the tightening member 132 and the inner wall of the groove, thereby adjusting the tightness of the conduit clamp.

Therefore, the groove structure 111 (with certain hardness) formed in the first surface 110 can still keep the stability of the catheter arranged in the groove structure 111 through the bundling mechanism 130 when different types of dialysis catheters (the outer diameter of the catheter is different), so that the dialysis catheter can adapt to different types of dialysis catheters, and the operation mode is simple and easy to understand and is convenient to use.

In addition, in the present embodiment, in order to further prevent the dialysis catheter from slipping off, a cover plate may be further provided on the groove structure 111. The cover plate may be disposed at one side edge of the first surface 110 along the direction of the groove structure 111, and the cover plate may be opened at one side to expose the groove structure 111; after the dialysis catheter is placed in the groove structure 111, it can be covered on the groove structure 111, thereby closing the cover plate. And the opposite side of first face 110 (the one side opposite with the one side of the rotation axis that sets up the apron promptly) can set up the buckle spare, and when the apron was closed, the border of apron can be held to the buckle spare to make the apron firmly cover groove structure 111, thereby can further avoid the dialysis catheter slippage, promote the stability of settling the dialysis catheter in groove structure 111.

For example, in a case where the assembly having the groove structure 111 is disposed on the first surface 110, please refer to fig. 2, the assembly is a foam sponge, and the foam sponge is disposed with at least two "t" shaped slits in parallel, where the "t" shaped slit represents the groove structure 111 of the assembly, and the dialysis catheter can be embedded into the "t" shaped slit.

The foam sponge is used as a combined piece connected to the first surface 110 and provided with a groove structure 111, the foam sponge is provided with at least two inverted T-shaped seams (namely the groove structure 111) in parallel, and the dialysis catheter can be embedded into the inverted T-shaped seams. The foam sponge has certain memory and flexibility, and the dialysis catheter is embedded into the inverted T-shaped seam, so that the dialysis catheter can be clamped and fixed, the catheter is not excessively extruded, and the operation of liquid in the catheter is blocked. And the cost of the foam sponge can be extremely low, and the manufacturing process only needs to be provided with the inverted-T-shaped seam, so that the foam sponge is extremely simple, can be produced in large quantities, and has extremely low cost. And when in use, the guide pipe is only required to be embedded into the T-shaped seam, and the operation is very simple.

Of course, the assembly may also be made of other elastic materials, such as latex, rubber, and the like, and the groove structure 111 may also be formed, but because such materials have weaker elasticity, when the groove structure 111 is formed, a "t" shaped slit having a certain width (i.e., the assembly of latex and rubber, the slit width of the "t" shaped slit is larger than that of the "t" shaped slit of the foam sponge) may be formed, and this is not limited herein.

Illustratively, the foam sponge may be attached to the body by adhesive. For example, a quick-dry adhesive tape adhesion, a hot-dry adhesive tape adhesion, a double-sided adhesive tape adhesion, etc., are used, and are not limited herein. The foam sponge is adhered to the main body through the adhesive, so that the adhesion between the foam sponge and the first surface 110 of the main body can be stably realized, the process is simple, the cost is extremely low, and the quality is reliable.

Referring to fig. 1 again, in the present embodiment, the connecting mechanism 121 may be a clamping member, a clamping end and a supporting end of the clamping member are respectively a first component 1211 and a second component 1212, and the supporting end may be the second surface 120 of the main body. The connecting mechanism 121 may be understood herein as a clip, one leg of which is the main body (i.e. the holding end: the second face 120 of the main body) and the other leg is provided separately (i.e. the holding end), so that the holding function can be achieved by the cooperation of the two legs. Such a connection mechanism 121 may be designed as an integrated clamp, which is easy to design and manufacture.

When in use, the fixing device can be directly clamped on the clothes of a dialysis patient (such as a jacket pocket, a side seam, a neckline or the like, or the chest part of the clothes can be twisted up and clamped under the allowable conditions), the use is very convenient, and the fixing device can adapt to almost all clothes, thereby ensuring the wide practicability of the dialysis catheter fixing device 100.

Of course, when the connecting mechanism 121 is a clamping member, it can also be a clip disposed on the second surface 120, and the clip can perform a clamping function to fix the dialysis catheter fixing device 100 on the clothes of the patient, which is not limited herein.

Referring to fig. 3, fig. 3 is a schematic view of a connection mechanism 121 according to an embodiment of the present disclosure. In this embodiment, the connecting mechanism 121 may also be a screw fastener, and a threaded hole matching the screw fastener may be opened on the second surface 120, and the screw fastener and the threaded hole are the first component 1211 and the second component 1212, respectively. Of course, the cap end portion of the screw fastener needs to be larger, for example, the diameter of the cap end portion of the screw fastener may be 2-10 mm. The tip of the screw fastener needs to be thin (for example, the diameter of the tip of the screw fastener can be designed to be 0.3-1 mm for safety, so as to avoid hurting people), so that the patient can wear the clothes.

The connecting mechanism 121 is a screw fastener (first component 1211), and the second surface 120 has a threaded hole (second component 1212) matching with the screw fastener. The tip of the screw clip can penetrate the clothes of the patient to be coupled with the screw hole, thereby fixing the dialysis catheter fixing device 100 to the clothes of the dialysis patient, and the operation is also simple, and can be adapted to almost all kinds of clothes.

Of course, the connection mechanism 121 may be other types of connection mechanisms 121, and it is sufficient that the dialysis catheter fixing device 100 can be fixed on the clothes of the dialysis patient, and may be selected according to actual needs, and is not limited herein.

To achieve the directional adjustment of the groove structure 111, please refer to fig. 4, fig. 4 is a schematic view of a dialysis catheter fixing device 100 capable of adjusting the relative direction between a first surface 110 and a second surface 120 according to an embodiment of the present disclosure. In this embodiment, the body may include a first layer that is a layer including the first face 110 and a second layer that is a layer including the second face 120. The first layer and the second layer can be connected by the connecting shaft 140 (the first layer and the second layer can be connected in a relatively rotatable manner in other ways, which are not limited herein), and the first layer and the second layer can be rotated around the connecting shaft 140 to adjust the direction of the groove structure 111.

Therefore, the limitation on the installation position of the dialysis catheter fixing device 100 on the clothes of a patient can be reduced as much as possible, the installation position and the installation direction can be accurately adjusted through rotation, the relative direction between the first layer and the second layer can be adjusted, and the first layer can be adjusted to a proper direction under the condition that the direction of the second layer is fixed, so that the direction of the catheter can be adapted, the installation limitation of the dialysis catheter fixing device 100 is reduced, and the dialysis catheter fixing device 100 is more practical.

For the catheter installed in the groove structure 111, at least an external force with a first predetermined value (e.g., 1-10N) is required to displace the dialysis catheter installed in the groove structure 111 relative to the groove structure 111, so as to secure the fixing effect of the groove structure 111 on the catheter as much as possible. The second surface 120 is provided with a connecting mechanism 121 (including a first component 1211 and a second component 1212 which are engaged with each other), the first component 1211 and the second component 1212 are engaged with each other after being engaged with each other at the outside of the interval between the first component 1211 and the second component 1212 (i.e., the first component 1211 and the second component 1212 can be engaged with each other at the interval between the clothes, so as to fix the main body to the clothes of the patient), and for the main body connected to the clothes, at least an external force (e.g., 10-100N) with a second preset value is required to remove the cloth from contact with the first component 1211 and the second component 1212, so that the main body can be firmly fixed to the clothes of the patient. Then, two dialysis catheters for dialysis of a patient can be respectively arranged in the two groove structures 111, and the first component 1211 and the second component 1212 are matched and connected after the clothes of the patient are dialyzed at intervals, so that the main body and the clothes are relatively fixed, and the dialysis catheters are fixed. Such an approach is simple and effective, and due to the simple construction of the dialysis catheter fixing device 100, the material requirements are low, and it is possible to keep the costs very low, which is also a very suitable option for the patient, with little economic burden on the patient.
