Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a tubing sampling port. Background Technology

[0002] Hemodialysis is a primary treatment for maintaining the lives of patients with kidney failure. The process involves drawing blood from the patient, purifying it using a hemodialysis device, and then returning it to the patient. The tubing used to hold the blood is called the hemodialysis circulation tubing. As an accessory to the hemodialysis circulation tubing, the sampling port is used to insert a syringe through the silicone tube during hemodialysis to collect blood samples for testing.

[0003] In actual blood collection, medical staff hold the sampling port with one hand and the syringe with the other, inserting the syringe needle into the silicone of the sampling port. Because there is a risk of needle prick in case of interference, the sampling port needs a safety design. However, the safety design of existing products involves adding baffles on both sides of the sampling port. This protects the fingers on the opposite side of the sampling port (usually the index and / or middle fingers) during puncture, but provides no protection for the fingers on the same side of the sampling port (usually the thumb). Even with significant disturbance, the fingers on the opposite side of the sampling port are still at risk of injury.

[0004] Therefore, in order to reduce the risk of hand injury during syringe puncture, it is necessary for those skilled in the art to provide a tubing sampling port that is easy to operate, highly safe, and can meet various gripping gestures. Summary of the Invention

[0047] Preferably, the main body 101 and the bracket 103 can be integrally injection molded.

[0048] Compared with the traditional sampling port, the pipeline sampling port 100 provided by the embodiment of the application movably connects a bracket 103 to the main body 101, the bracket 103 can fix the syringe 300 when working, and drive the needle of the syringe 300 to accurately pierce into the puncture plug 102 by moving relative to the main body 101, in the puncture process, the puncture path of the syringe 300 is fixed and not interfered by the outside world, and the whole process does not face any human tissue, that is, there is no risk of puncture injury, the operation is convenient, and the safety is high.

[0049] In addition, the bracket 103 can cover the periphery of the puncture plug 102 in the case of not being used, thereby playing a role of protective cover, avoiding the position of the puncture plug 102 from being polluted, and causing the heat source (allergen) to enter the blood to cause pollution when puncture sampling.

[0050] In some embodiments, the bracket 103 and the main body 101 can be rotationally matched.

[0051] Specifically, the main body 101 is provided with a first connecting piece 1011, the bracket 103 is provided with a second connecting piece 1031, the second connecting piece 1031 and the first connecting piece 1011 can be rotationally matched, so that the bracket 103 drives the syringe 300 to pierce into the puncture plug 102.

[0052] In order to facilitate the rotational matching of the bracket 103 and the main body 101, the second connecting piece 1031 can be a rotating groove, and the first connecting piece 1011 can be a rotating shaft, the rotating groove is rotated relative to the rotating shaft, so that the bracket 103 drives the syringe 300 to pierce into the puncture plug 102.

[0053] In some embodiments, the bracket 103 and the main body 101 can be matched by rotation + sliding.

[0054] Specifically, the first connecting member 1011 comprises a fixed plate 10111 and a protrusion 10112 (or a rotating protrusion 10112) arranged on the fixed plate 10111, the protrusion 10112 can be a cylindrical protrusion 10112, the second connecting member 1031 comprises a guide rail 10311 and a rotating point 10312 (or a rotating groove) arranged on the guide rail 10311, the guide rail 10311 is provided with a sliding groove, after the protrusion 10112 is engaged with the guide rail 10311, the rotating point 10312 and the protrusion 10112 can be rotatably matched, and the protrusion 10112 can slide along the sliding groove of the guide rail 10311.

[0055] At the same time, the main body 101 is further provided with an avoiding groove 1012, the length of the avoiding groove 1012 is greater than or equal to the length of the guide rail 10311, when the guide rail 10311 moves (rotates or moves) relative to the protrusion 10112, the avoiding groove 1012 is used for accommodating the guide rail 10311, that is, the avoiding groove 1012 is a movement path of the guide rail 10311, the guide rail 10311 can pass through the avoiding groove 1012, so as to ensure that the rotation or movement of the guide rail 10311 will not be blocked by the main body 101.

[0056] More specifically, the number of the second connecting member 1031, the first connecting member 1011 and the avoiding groove 1012 is two, and the avoiding groove 1012 corresponds to the guide rail 10311 one by one, the two second connecting members 1031 are fixed to the same end of the bracket 103, when installed, the bracket 103 and the main body 101 are combined into one through the engagement of the two guide rails 10311 and the protrusions 10112.

[0057] In some embodiments, the bracket 103 comprises a first extension 1032 and a second extension 1033, the first extension 1032 and the second extension 1033 extend along the same side of the bracket 103, the first extension 1032 is provided with a first fixed groove 1034, and the second extension 1033 is provided with a second fixed groove 1035, the first fixed groove 1034 and the second fixed groove 1035 are respectively used for fixing the barrel and the needle of the syringe 300.

[0058] It should be noted that the first fixed groove 1034 and the second fixed groove 1035 can be set as three-quarter circular grooves, the first fixed groove 1034 can be engaged together with the barrel of the syringe 300 through the deformation of the plastic part, thereby fixing the barrel of the syringe 300, and the second fixed groove 1035 can be engaged together with the needle of the syringe 300 through the deformation of the plastic part, thereby fixing the needle of the syringe 300.

[0059] In some embodiments, the main body 101 is provided with a first clamping structure 1013, and the second extension 1033 is further provided with a second clamping structure 1036, which can be clamped with the first clamping structure 1013 to fix the bracket 103 to the main body 101.

[0060] As a preferred, the second clamping structure 1036 can be a clamping groove, and the first clamping structure 1013 can be a clamping protrusion, of course, the clamping protrusion can be a hemispherical protrusion, and the clamping groove can be a hemispherical clamping groove, which can be clamped by the hemispherical clamping protrusion and the hemispherical clamping groove to fix the bracket 103 when the bracket 103 is retracted.

[0061] In some embodiments, the main body 101 is further provided with a groove 1014, which can accommodate at least part of the structure of the second extension 1033.

[0062] It can be understood that the groove 1014 can be arranged between the two first clamping structures 1013, and when the two second clamping structures 1036 on the bracket 103 are clamped with the two first clamping structures 1013 on the main body 101 one by one (i.e. when the bracket 103 is retracted), the groove 1014 can accommodate the excess structure of the end of the second extension 1033, which can ensure that the bracket 103 is tightly matched with the puncture plug 102, and at the same time, the bracket 103 occupies less space when retracted, and the whole is more exquisite.

[0063] In some embodiments, the bracket 103 includes a cover plate 1037, and the first extension 1032 and the second extension 1033 are arranged on the cover plate 1037. The inner side wall of the cover plate 1037 is provided with a cap 1038, which can be covered with the puncture plug 102 in the non-working state, so as to achieve the purpose of dustproof.

[0064] In this way, when the bracket 103 is retracted (non-working state), the cap 1038 on the cover plate 1037 can be tightly covered with the puncture plug 102, thereby playing a role in protecting the puncture plug 102.

[0065] In some embodiments, the main body 101 includes a baffle 1015, a protrusion 1016 and a pipeline connection end 1017. The baffle 1015 is used to protect the fingers away from the puncture side of the syringe 300; the protrusion 1016 is arranged on the side of the baffle 1015 away from the puncture plug 102, and both the baffle 1015 and the protrusion 1016 can be held by medical staff during use; the pipeline connection end 1017 is arranged through the protrusion 1016, and the pipeline connection end 1017 is used to connect the external pipeline 200.

[0066] It should be noted that, please see Figure 7The connection mode of the pipeline connecting end 1017 and the external pipeline 200 is bonding through a plastic adhesive (such as cyclohexanone), wherein the inner diameter of the pipeline connecting end 1017 is the same as the outer diameter of the external pipeline 200, and the narrowest part of the pipeline connecting end 1017 is the same as the narrowest part of the external pipeline 200, so as to avoid blood accumulation and blood clotting caused by changes in the flux of the external pipeline 200.

[0067] Of course, according to the safety requirements, the baffle 1015 extends along the outer periphery of the puncture plug 102 to form an overall planar structure, which plays a comprehensive protection role. In this way, the baffle 1015 on both sides of the sampling port along the pipeline direction can expand the area of the existing baffle 1015 to protect the fingers that hold the sampling port and are exposed.

[0068] In order to ensure the stability of holding, the baffle 1015 and the protrusion 1016 are both provided with the convex stripes 1018. For example, the convex stripes 1018 are arranged on the finger pressing position on the baffle 1015 and the sidewalls on both sides of the protrusion 1016. The convex stripes 1018 can increase the friction between the fingers and the main body 101, increase the stability of gripping, and improve the safety.

[0069] It should be noted that the main body 101 is an integrally injection molded structure, and the material of the main body 101 can be any biologically friendly material that is not prone to blood clotting, such as PVC, PE, PP, etc. The baffle 1015 and the protrusion 1016 are part of the integrally injection molded structure.

[0070] In some embodiments, the baffle 1015 is also provided with a limiting block 1019, and the limiting block 1019 abuts against the bracket 103 to keep the bracket 103 in a fixed posture when the syringe 300 is fixed.

[0071] That is, when the bracket 103 is in a fully expanded state (this state is a state of waiting to install the syringe 300), the limiting block 1019 plays a limiting role, so that the bracket 103 can keep a stable state when the syringe 300 is installed, and will not be displaced due to deformation caused by pressing, which affects the installation of the syringe 300.

[0072] In summary:

[0073] 1) In the working condition of the bracket 103, please refer to Figure 8 The bracket 103 can guide the syringe 300 to puncture into the puncture plug 102 of the sampling port in a safe manner, and the specific use method is as follows:

[0074] Step 1: Open the bracket 103, first rotate the bracket 103 counterclockwise by 90°, and then push the guide rail 10311 to the bottom;

[0075] Second step: install the syringe 300 on the bracket 103, rotate the bracket 103 clockwise by 90 degrees, and the needle pierces into the puncture plug 102;

[0076] Third step: push and pull the syringe 300 to sample or inject medicine;

[0077] Fourth step: reverse the first and second steps.

[0078] 2) Safety principle of the bracket 103

[0079] It can be understood that, please refer to Figure 9 In general, in the sampling method of the sampling port, the needle of the syringe 300 is perpendicular to the sampling port, and in the case of disturbance, the needle of the syringe 300 is easy to pierce the same side of the finger of the baffle 1015, and even if there is protection of the baffle 1015, in the case of large disturbance, the back side of the finger of the baffle 1015 still has the risk of injury.

[0080] And the sampling port provided by the embodiment of the application sets the bracket 103, and the travel path of the needle of the syringe 300 before piercing the sampling port is changed from being perpendicular to the sampling port and the sampling operation of the finger to being parallel to the sampling port and the finger, that is, even if disturbance occurs, the needle of the syringe 300 fixed to the bracket 103 and parallel to the finger has extremely low possibility and ability to injure the finger, thereby greatly improving the safety of sampling / injection.

[0081] 3) When not in use, the bracket 103 can be clamped to the periphery of the puncture plug 102 of the sampling port, and functions as a protective cover to avoid the puncture plug 102 at the sampling port being contaminated, causing a heat source (allergen) to enter the blood when puncture sampling.

[0082] In addition, the embodiment of the application can meet various gestures for gripping the sampling port by optimizing and adjusting the existing sampling port structure, and increase the operation comfort.

[0083] Please refer to Figures 10 to 12 :

[0084] The first gripping method (gripping method one): the index finger and the middle finger are placed below the protrusion 1016, the thumb is placed above and presses the baffle 1015 downward, and the friction force formed by pressing fixes the sampling port.

[0085] The second gripping method (gripping method two): the index finger and the middle finger are clamped below the protrusion 1016, and the sampling port is fixed by relying on the friction force between the protrusion 1016 and the index finger and the middle finger.

[0086] The third gripping method (gripping method three): the thumb and the index finger pinch the protrusion 1016, and the sampling port is fixed by the friction force between the thumb, the index finger and the protrusion 1016.

[0087] In the prior art, there are different designs of sampling ports, which can meet the basic use requirements, but do not take into account the practicability, safety, comfort and use habits of medical staff. For example, some sampling port products can be held in two or three ways, but the clamping force is small due to the narrow clamping position in the second holding way, the holding stability is poor in the third holding way, and it is easy to be disturbed by the pipeline force to swing down in the direction perpendicular to the sampling port, and the holding feeling is not good; some sampling port products can be held in three ways, but the feeling of the first holding way is not good, the thumb is pressed against the vertical baffle 1015, and the thumb is painful, and the use experience is poor; some sampling port products can be held in the first holding way, and the holding feeling is good, but there is no baffle 1015, and there is a risk of finger injury.

[0088] Compared with the traditional sampling port, the pipeline sampling port 100 provided by the embodiment of the application can take into account the functionality of multiple gesture holding and can protect the fingers to prevent finger injury caused by puncture failure, and among the first, second and third holding ways, the holding stability of the first holding way is the best and the safety is the best, so the application mainly uses the first holding way to ensure the best holding and use experience while meeting the holding operation of the second and third holding ways.

[0089] The sampling port provided by the embodiment of the application is that the baffle 1015 on the main body 101 is designed as a plane structure as a whole, and the baffle 1015 is designed with a convex pattern 1018, and the convex block 1016 has a wide enough size, which ensures that the fingers have a good experience (comfortable) and a more secure grip when gripping.
