DETAILED DESCRIPTION

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0025] One of the preferred embodiments of the present application is as follows: Figures 1 to 4 As shown, a fixing device for a medical three-way connector includes a base 1, a strap assembly 2, a limiting assembly 3 and a limiting assembly 2 4, wherein the strap assembly 2 is installed on the base 1, and the strap assembly 2 can wear the fixing device on the patient's arm; the limiting assembly 1 3 is installed on the base 1, which can limit and fix the three-way connector 5, and then connect the three-way connector 5 and the infusion tube 6; the limiting assembly 2 4 is installed on the base 1, and the infusion tube 6 connected to the three-way connector 5 can be limited and fixed through the limiting assembly 2 4.

[0026] It can be seen that the three-way connector 5 can be well fixed on the patient's arm through the strap assembly 2, and there is no need to use medical tape for fixing. It is simple and convenient, and the infusion tube 6 can also be limited and fixed, so that the infusion tube 6 and the three-way connector 5 are not prone to detachment, which greatly improves safety.

[0027] It should be noted that the fixing device is not limited to being worn on the patient's arm, and the fixing device can also be fixed to the edge of the bed or the bed rails through the strap assembly 2.

[0028] One of the embodiments of the present application is as follows: Figure 2 As shown, the limiting component 2 4 includes a plurality of limiting blocks 401, which are installed on the base 1, and the side of the limiting block 401 is provided with a limiting groove 402 that cooperates with the infusion tube 6, and the middle part of the limiting groove 402 is bent into an arc structure so that the limited infusion tube 6 is in a bent state.

[0029] It is understandable that if Figure 4 As shown, the infusion tube 6 can be clamped and limited in the limiting groove 402. Since the middle part of the limiting groove 402 is bent, the infusion tube 6 engaged therewith will also be in a bent state. Figure 2 As shown, when the infusion tube 6 is pulled or dragged toward the direction of the three-way connector 5, the limiting groove 402 at the bend will exert a certain resistance on the infusion tube 6, thereby making it difficult for the infusion tube 6 to move out of the limiting groove 402, thereby playing an anti-slip effect.

[0030] It should be noted that the bend of the infusion tube 6 is not a kink, that is, the bent infusion tube 6 will not have any influence on the flow of the liquid in the tube, thus ensuring the smooth flow of the infusion tube 6, and also limiting and fixing the infusion tube 6 and playing a role in preventing it from falling off. Of course, in order to better limit the infusion tube 6, the limiting groove 402 at the bend preferably adopts a "sinusoidal" structure, that is, a structure with multiple bends, thereby improving the limiting ability.

[0031] like Figure 2 As shown, when the infusion tube 6 moves toward the direction of the three-way connector 5 (toward the right), it can be locked by the limiting groove 402. However, if the infusion tube 6 is pulled or dragged toward the opening direction of the limiting groove 402, when the pulling force of the infusion tube 6 is greater than the limiting clamping force of the limiting groove 402, the infusion tube 6 will easily fall out of the limiting groove 402.

[0032] Therefore, if Figure 2 As shown, the limiting assembly 2 4 also includes a baffle 403, which can be installed on the side of the limiting block 401 through the elastic sliding of a spring. When installing the infusion tube 6, the baffle 403 can be pulled in a direction away from the limiting groove 402; when the infusion tube 6 is clamped in the limiting groove 402, after releasing the hand, under the elastic force of the spring, the baffle 403 will move and reset and abut against the opening of the limiting groove 402, thereby putting the infusion tube 6 in a locked state, thereby greatly improving the limiting ability of the infusion tube 6.

[0033] In actual use, there may be such a problem: since the three-way connector 5 is fixed by the strap assembly 2, its position is fixed, which causes excessive bending between the infusion tube 6 and the fixing device, affecting the effect of infusion.

[0034] In order to solve the above technical problems, one of the embodiments of the present application is as follows: Figure 1 and Figure 3 As shown, the base 1 includes a substrate 101, a mounting plate 102 and a positioning assembly 103, the mounting plate 102 is rotatably mounted on the substrate 101, the strap assembly 2 is mounted on the substrate 101, and the limiting assembly 1 3 and the limiting assembly 2 4 are both mounted on the mounting plate 102.

[0035] When in use, when the three-way joint 5 needs to be rotated and adjusted, the positioning assembly 103 can unlock the mounting plate 102, that is, the mounting plate 102 is in a free state at this time, and the mounting plate 102 can be rotated and adjusted. When the three-way joint 5 is adjusted, the positioning assembly 103 can lock the mounting plate 102, that is, limit the adjusted three-way joint 5.

[0036] As a further description of the above technical solution: the positioning component 103 has various structural forms, including but not limited to the following two:

[0037] Structure 1 (not shown): The positioning assembly 103 includes a positioning screw, and the positioning screw and the mounting plate 102 are matched through threads.

[0038] In specific use, when the mounting plate 102 needs to be locked, the positioning screw can be rotated in a spiral manner to move the positioning screw until it contacts the base plate 101, that is, an extrusion force is generated between the positioning screw and the base plate 101 to lock the mounting plate 102. When the three-way connector 5 needs to be adjusted, the positioning screw can be rotated in a reverse spiral manner to separate the positioning screw and the base plate 101.

[0039] Structure 2 (such as Figure 3 As shown): The positioning assembly 103 includes an arc groove 1032, a fixing rod 1031 and a threaded sleeve 1033, the arc groove 1032 is arranged on the mounting plate 102, the fixing rod 1031 is installed on the base plate 101 and passes through the arc groove 1032, and the threaded sleeve 1033 and the fixing rod 1031 are matched through threads.

[0040] In specific use, when the mounting plate 102 needs to be locked, the threaded sleeve 1033 can be spirally rotated to move the threaded sleeve 1033 until it abuts against the mounting plate 102, that is, an extrusion force is generated between the threaded sleeve 1033 and the mounting plate 102 to lock the mounting plate 102. When the tee joint 5 needs to be adjusted, the threaded sleeve 1033 can be spirally rotated in the opposite direction to separate the threaded sleeve 1033 and the mounting plate 102.

[0041] It should be noted that both methods can meet actual needs, and technicians in this field can choose according to actual conditions.

[0042] One of the embodiments of the present application is as follows: Figure 4 As shown, a flexible layer, such as a rubber layer, can be provided inside the limiting groove 402, so that the infusion tube 6 and the limiting groove 402 are in flexible contact, and no rigid extrusion is generated on the infusion tube 6, and the friction between the infusion tube 6 and the limiting groove 402 can be increased, thereby improving the limiting effect. Chamfered structures 7 can be provided at both ends of the limiting groove 402, so that the infusion tube 6 can be more easily inserted into the limiting groove 402, and on the other hand, when the infusion tube 6 is bent along the end of the limiting groove 402, due to the action of the chamfered structure 7, the bending of the infusion tube 6 will also play a transitional role, that is, the infusion tube 6 will not be rigidly bent, so as to ensure the safety of the infusion.

[0043] In this embodiment, Figure 1 As shown, the strap assembly 2 includes a pair of strap bodies 201 . The strap bodies 201 are installed on both sides of the base plate 101 , and the strap bodies 201 are matched with each other through a connecting assembly.

[0044] It is understandable that when in use, the two belt bodies 201 are wrapped around the patient's arms, and then connected through the connecting components, the fixing device can be worn on the arm, which is simple and convenient. The connecting components here can use Velcro, snap buckles, tethers or buttons.

[0045] Of course, in order to make the device more comfortable to wear, the substrate 101 can be made of elastic material, such as rubber or foam, and the side of the substrate 101 away from the mounting plate 102 is an arc-shaped structure that fits the arm, which can better fit the arm curve and reduce discomfort.

[0046] In this embodiment, Figure 3 As shown, the limiting component 3 includes a plurality of arc-shaped clamping plates 301 , and the arc-shaped clamping plates 301 are mounted on the mounting plate 102 , and the arc-shaped clamping plates 301 cooperate with the three-way connector 5 .

[0047] It should be noted that the arc-shaped clamping plates 301 are preferably provided in three groups, that is, they are adapted to the three joints of the three-way joint 5, and the three arc-shaped clamping plates 301 are distributed at equal distances, that is, there is a ninety-degree angle between two adjacent arc-shaped clamping plates 301, so that the three-way joint 5 can be well limited and fixed.

[0048] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
