Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a medical connector hose connection device. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Normally, tubing and connectors in fluid circuits have standard recommended fit dimensions. In this case, the inner diameter of the tubing is slightly smaller than the outer diameter of the connector, making manual connection easier and preventing loosening under normal use. However, medical equipment tubing carries various reagents or solutions with high concentrations. Over time, precipitation and crystallization can occur in the tubing, eventually clogging it. When the power pump is running continuously, the pressure inside the tubing gradually increases, leading to problems such as leakage, loosening, and air leakage in the tubing and connectors. Additionally, high-pressure connections in the fluid circuit, subjected to even higher pressures, can also experience leakage and loosening at the connectors.

[0004] To overcome the above problems, hydraulic engineers do not use the standard recommended size in certain pipeline designs. They use a hose one size smaller than the recommended size for the same connector, resulting in a tighter connection and preventing leaks, loosening, and air leaks. However, in this case, the outer diameter of the hose will be smaller than the outer diameter of the connector, making it very difficult for operators to insert it tightly by hand, and prolonged operation can cause finger injuries.

[0005] To overcome the aforementioned problem, a common method is to soak the hose in 60°C warm water for 2 minutes to soften it before inserting it into the connector. This method requires precise control of water temperature and time. Furthermore, the hose cools rapidly after being removed from the warm water and hardens before being properly inserted, thus this method offers little improvement and is inefficient. Utility Model Content

[0006] The purpose of this invention is to at least solve the technical problems of difficulty in connecting and loosening existing medical tubing and connectors. This purpose is achieved through the following technical solution:

[0007] This utility model discloses a medical connector hose connection device, comprising:

[0046] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0047] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0048] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0049] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0050] like Figures 1 to 7 As shown in the accompanying drawings, X represents the first direction, Y represents the second direction, and Z represents the third direction. This utility model proposes a medical connector 60 and hose 50 connection device, including a base 10, a first fixing seat 20, a second fixing seat 30, and a drive assembly 40. The first fixing seat 20 is mounted on the base 10 in a manner movable along the first direction. The second fixing seat 30 is mounted on the base 10 and is positioned opposite to the first fixing seat 20 in the first direction. One of the first fixing seat 20 and the second fixing seat 30 is used to install the medical hose 50, and the other is used to install the medical connector 60. The drive assembly 40 includes a linear drive mechanism 41 and a power unit 42. The power unit 42 is connected to the second fixing seat 30 via the linear drive mechanism 41. The power unit 42 can drive the first fixing seat 20 to move along the first direction toward the second fixing seat 30 to connect the medical hose 50 and the medical connector 60.

[0051] As can be seen, the medical connector 60 and hose 50 connecting device proposed in this utility model fixes the medical hose 50 and connector 60 respectively through the first fixing seat 20 and the second fixing seat 30, and connects the medical hose 50 and connector 60 through the driving component 40. By fixing the hose 50 and connector 60 with mechanical structure, the hand is prevented from being injured during insertion. Furthermore, by using the force-saving lever effect of mechanical structure or external driving force, the first fixing seat 20 and the second fixing seat 30 move towards each other in the first direction to insert the medical hose 50 and connector 60, reducing the disadvantages of laborious and inefficient manual operation.

[0052] For example, the first fixing base 20 may have an insertion hole for mounting the connector 60, and the second fixing base 30 may have a mounting hole 34 for placing the tubing 50. The first fixing base 20 and the second fixing base 30 may be rectangular in shape, and the base 10 may also be rectangular in shape. To limit the movement direction of the first fixing base 20 and the second fixing base 30, a track or groove may be provided on the base 10 for guiding and limiting. The linear drive mechanism 41 may be a lead screw mechanism, a gear and rack mechanism, a guide rod and slider mechanism, etc., and the power unit 42 may be a manually driven wheel, a movable handle 422, or an electrically driven motor, etc., which converts the rotational motion into the linear motion of the linear drive mechanism 41 and then transmits it to the first fixing base 20 to connect the medical tubing 50 to the connector 60 with ease.

[0053] In some embodiments of this utility model, the linear drive mechanism 41 includes a rack stepper 411, which is disposed on the base 10 and is movable in a first direction. A first fixed seat 20 is mounted on the rack stepper 411. The power unit 42 has a transmission tooth 424 that meshes with the rack stepper 411. The power unit 42 is configured to drive the rack stepper 411 to move in the first direction through the transmission tooth 424.

[0054] It can be seen that the transmission gear 424 of the power unit 42 drives the rack stepper rod 411 to move in the first direction, so that the first fixed seat 20 and the second fixed seat 30 move towards each other, thereby making it easier to connect the medical hose 50 to the connector 60.

[0055] For example, the rack stepper 411 can be a cylindrical rod or a prismatic rod with a rack along its axial direction. The rack stepper 411 can be inserted into the sliding hole 11 on the base 10. The sliding hole 11 has a sliding opening 111 on the top side of the base 10. Both the sliding hole 11 and the sliding opening 111 extend along the first direction, so that part of the first fixed seat 20 can be located in the sliding opening 111 and connected to the rack stepper 411. This part can move along the sliding opening 111. The first fixed seat 20 can be fixed to the rack stepper 411 by snap-fit ​​or bolt, and avoids the rack part. The power unit 42 can be driven by a motor, a manual wheel, or an adjustable wrench. The transmission teeth 424 on the power unit 42 mesh with the rack, so that the rotation of the power unit 42 can be transmitted to the rack stepper 411, thereby driving the first fixed seat 20 to move along the first direction.

[0056] In some embodiments of this utility model, the power unit 42 includes a fixed handle 421, a movable handle 422, and an elastic part 426. The fixed handle 421 and the first fixed base 20 are respectively located on both sides of the base 10 along a second direction, which is perpendicular to the first direction. The movable handle 422 has a first end and a second end along its own length direction, and the first end and the second end of the movable handle 422 are rotatably connected to the base 10. The opposite ends of the elastic part 426 are respectively connected to the first end and the transmission tooth 424. The elastic part 426 is configured to be compressible along the length direction of the movable handle 422. The movable handle 422 has a first rotation angle range and a second rotation angle range. In the first rotation angle range, the transmission tooth 424 meshes with the rack stepper 411, and the elastic part 426 is in a compressed state. In the second rotation angle, the transmission tooth 424 separates from the rack stepper 411.

[0057] As can be seen, the movable handle 422 is rotatably connected to the base 10 and engages with the rack and pinion stepper 411, so that turning the movable handle 422 can drive the movable handle 422 to rotate, thereby pushing the rack and pinion stepper 411 to move in the first direction, so that the first fixed seat 20 and the second fixed seat 30 move towards each other, and the medical tubing 50 is connected to the connector 60 with ease.

[0058] For example, the structure of the power unit 42 with a fixed handle 421 and a movable handle 422 can refer to the existing sliding clamp. The rotation of the movable handle 422 drives the rack stepper 411 to move linearly. During the rotation of the movable handle 422, in order to ensure that the transmission gear 424 and the rack stepper 411 mesh normally, an elastic part 426 needs to be provided so that the distance between the first end of the movable handle 422 and the rack stepper 411 has elastic redundancy during the rotation of the movable handle 422, so as to prevent the transmission gear 424 and the rack stepper 411 from jamming due to the continuous rotation of the movable handle 422, and thus being unable to continue moving. Specifically, as the movable handle 422 rotates toward the rack stepper 411 and the two gradually intersect perpendicularly, the elastic part 426 gradually presses down. As the movable handle 422 continues to rotate, tending to separate from the rack stepper 411, the elastic part 426 continues to press the transmission teeth 424 onto the rack stepper 411. When the second rotation angle is reached, the transmission teeth 424 separate from the rack stepper 411.

[0059] In some embodiments of this utility model, the drive assembly 40 further includes a first reset part 423. The opposite sides of the first reset part 423 are connected to the movable handle 422 and the base 10, respectively. The first reset part 423 has elasticity and drives the second end to move toward the fixed handle 421 in the first direction through its own elasticity.

[0060] As can be seen, by setting the first reset part 423, the movable handle 422 can continuously swing along the first direction to drive the rack stepper rod 411 to move along the first direction, so as to connect the medical hose 50 and the connector 60 with less effort.

[0061] For example, the first reset part 423 can be a spring or other elastic structure, with its opposite ends connected to the movable handle 422 and the base 10 respectively. The connection method can be snap-fit ​​or hook-fit. The first reset part 423 can be tilted relative to the first direction according to actual needs. When the movable handle 422 is turned, the movable handle 422 drives the rack stepper 411 to move along the first direction toward the second fixed seat 30. At this time, the anti-reverse block 425 connected to the base 10 rotates and locks the rack stepper 411. When the movable handle 422 is released, the first reset part 423 drives the movable handle 422 to reset so that the rack stepper 411 can be turned to continue.

[0062] In some embodiments of this utility model, the first fixing seat 20 includes a first seat body 21 and a second seat body 22. The first seat body 21 is mounted on the rack stepper rod 411, and the second seat body 22 is detachably connected to the first seat body 21. The second seat body 22 is provided with a plug hole 221 for inserting the medical barbed connector 60.

[0063] As can be seen, the first base 21 and the second base 22 are detachably connected to allow for the provision of multiple second bases 22 to match different types of connectors 60. The second base 22 can also be rotatably connected to the first base 21, providing better compatibility when inserting multi-interface connectors 60, such as Y-type connectors 60 and T-type connectors 60.

[0064] For example, the second base 22 can be detachably connected to the first base 21 by snap-fit ​​or bolt fixing, and the first base 21 can be connected to the base 10 by snap-fit ​​or bolt fixing, or it can be directly integrally formed with the base 10. The second base 22 can be provided with a circular insertion hole 221, the axis of which is parallel to the first direction, or can be parallel to the first direction during the rotation of the second base 22.

[0065] In some embodiments of this utility model, the second fixing base 30 includes:

[0066] The third seat 31 is mounted on the rack stepper 411 and is positioned opposite to the second fixed seat 30 in the first direction;

[0067] The clamping body 32 is disposed opposite to the third seat body 31 along a third direction. The third direction is perpendicular to the first direction and the second direction respectively. A mounting hole 34 is formed between the clamping body 32 and the third seat body 31. The axis of the mounting hole 34 is parallel to the first direction and is used to insert the medical tubing 50.

[0068] The locking mechanism 33 is connected to the third seat 31 and the clamping body 32 respectively, and is used to drive the clamping body 32 to clamp the medical tubing 50 with the third seat 31 in a third direction.

[0069] As can be seen, by clamping and locking the hose 50, it is not easy for the hose 50 to shift during the docking process. The locking mechanism 33 can further clamp the hose 50, improving the reliability of docking.

[0070] For example, the third seat 31 can be fixed on the base 10 by the fixing platform 12 on the base 10. The fixing platform 12 can be provided with a groove to engage with the third seat 31. The clamping body 32 can be arranged in a scissor shape opposite to the third seat 31, or it can be arranged opposite to the third seat 31 by means of a support track or other structure, and can move towards each other. The locking mechanism 33 can be a structure similar to a quick release mechanism, or it can be screwed to the third seat 31 and the clamping body 32 by means of a screw structure to tighten the two.

[0071] In some embodiments of this utility model, one end of the clamping body 32 along the second direction is rotatably connected to the base 10 and rotated to be opposite to the third base 31 or rotated to be separated from the third base 31. The locking mechanism 33 includes a quick-release wrench assembly, which is located at the other end of the clamping body 32 along the second direction and connected to the third base 31. The quick-release wrench assembly has a first rotational position that drives the clamping body 32 to press against the third base 31 and a second rotational position that allows the clamping body 32 to separate from the third base 31.

[0072] As can be seen, by rotating the clamping body 32 to the base 10, the clamping body 32 can clamp the hose 50 during rotation. Furthermore, by setting the quick-release wrench assembly, the clamping body 32 is further pressed against the third base 10, thereby improving the clamping effect on the hose 50.

[0073] For example, the quick-release wrench assembly can refer to the existing quick-release wrench structure, such as the quick-release wrench for a bicycle seat. The quick-release wrench assembly includes a quick-release head 331, a quick-release pin 332, a rubber sleeve seat 334, and a washer 333. The quick-release head 331 is rotatably connected to one end of the quick-release pin 332. The quick-release pin 332 is sequentially inserted through the rubber sleeve seat 334, the washer 333, the clamping body 32, and the third seat 31. The rubber sleeve seat 334 abuts against the arc-shaped end of the quick-release head 331. The washer 333 is clamped between the rubber sleeve seat 334 and the clamping body 32. The quick-release head 331 rotates by itself, causing the arc-shaped end to press against the rubber sleeve seat 334, thereby pressing the clamping body 32 against the third seat 31.

[0074] In some embodiments of the present invention, the second fixing base 30 further includes an elastic anti-slip layer 35 disposed on at least a portion of the hole wall of the mounting hole 34.

[0075] It is evident that by setting an anti-slip layer, the friction between the second fixing seat 30 and the hose 50 is increased, thereby improving the reliability of the connection between the two and making the hose 50 less prone to slipping.

[0076] For example, a silicone sheet can be attached to the wall of the mounting hole 34, and the silicone sheet can be arranged around the circumference of the mounting hole 34, or multiple protrusions can be provided on the mounting hole 34, and the protrusions can also be arranged around the circumference of the mounting hole 34, to improve the connection reliability of the hose 50.

[0077] In some embodiments of this utility model, the second fixed base 30 further includes a second reset part 36, which is connected to the clamping body 32 and the base 10 respectively. The second reset part 36 has elasticity, and the second reset part 36 drives the clamping body 32 to rotate away from the third base 31 by its own elasticity.

[0078] As can be seen, by setting the second reset part 36, the clamping body 32 can be quickly separated from the third seat body 31 after the locking mechanism 33 is released, thereby facilitating the removal of the hose 50.

[0079] For example, the second reset part 36 may be a retaining ring 361, and the clamping body 32 is rotatably connected to the base 10 through a flat-headed grooved cylindrical pin 362. The retaining ring 361 can be embedded in the cylindrical pin 362 and pressed between the base 10 and the clamping body 32, thereby driving the clamping body 32 to separate from the third seat 31 when the locking mechanism 33 is relaxed.

[0080] In some embodiments of this utility model, the fixed handle 421 is provided with a hand support 4211 on the side away from the movable handle 422 along the first direction, and a hand grip groove 4212 is formed between the hand support 4211 and the base 10.

[0081] It is evident that by setting the hand rest 4211, the fixed handle 421 is made easier to grip, improving the comfort during use.

[0082] For example, the groove wall of the hand grip groove 4212 can be set as a curved surface to improve comfort.

[0083] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
