The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to better understand the aspects of the present application, a further detailed description of the present application will be provided below with reference to the accompanying drawings and detailed description.

The terms "upper end, lower end, left side, right side" and the like are defined based on the drawings of the specification.

Referring to fig. 4 to 10, the pipeline sampling port 100, which is also called a drug injection tee, provided in the embodiments of the present application generally performs a blood sampling or drug injection operation through the sampling port, and the sampling port provided in the embodiments of the present application includes a main body 101 and a puncture plug 102, where the puncture plug 102 is disposed on the main body 101, and the puncture plug 102 is used for a syringe to penetrate so as to collect blood, and meanwhile, the puncture plug 102 is inclined to one side, and the puncture plug 102 adopting the inclined arrangement can make the injury smaller and safer.

Further, in order to be convenient for fixed sampling mouth and protect medical personnel's finger, main part 101 includes backplate 1011 and lug 1012, and wherein, backplate 1011 is used for protecting the finger that deviates from syringe puncture one side, and the lug 1012 is located backplate 1011 and is deviate from the one side of puncture plug 102, and in the use, backplate 1011 and lug 1012 all can supply medical personnel to hold.

In some embodiments, the body 101 is a unitary injection molded structure, and the material of the body 101 may be any material that is bio-friendly and not prone to clotting, such as PVC, PE, PP. Guard 1011 and tab 1012 are part of this one-piece injection molded structure.

It should be noted that, when the medical staff holds the sampling port to collect blood, there are three gestures as follows:

first mode of grip (gesture): referring to fig. 1, the index finger and the middle finger are pressed against the sampling port, the thumb presses the sampling port downward, and the friction force formed by pressing fixes the sampling port.

The second way of holding (gesture): referring to fig. 2, the index finger and the middle finger hold the sampling port at the bottom, and the sampling port is fixed by the friction force between the sampling port and the index finger and the middle finger.

Third grip (three gestures): referring to fig. 3, the thumb and the index finger clamp the sampling port, and the friction force between the thumb, the index finger and the sampling port is used to fix the sampling port.

In the prior art, different designs are arranged on the sampling port, so that the basic use requirement can be met, but the practicality, the safety, the comfort and the use habit of medical staff are not considered. For example, when two-gesture and three-gesture holding are performed on some sampling port products, the holding force is small due to the fact that the holding position of the two gestures is narrow, the holding stability of the three gestures is poor, the three gestures are easy to be interfered by the force of the pipeline 200 to swing up and down in the direction perpendicular to the sampling port, and the holding hand feeling is poor; some sampling port products can be held by three gestures, but the hand feeling of one gesture is poor, the thumb is propped against the vertical baffle, and the sampling port products are subjected to larger pressure, the thumb is painful, and the use experience is poor; some sampling port products can be held by a gesture, the holding hand feeling is good, but no baffle is provided, and the risk of damaging fingers is caused.

Compared with the traditional sampling port, the pipeline sampling port 100 provided by the embodiment of the application can be used for considering the holding functionality of various gestures and protecting fingers, so that finger damage caused by puncture errors is prevented, and in the first gesture, the second gesture and the third gesture, the holding stability of the first gesture is optimal, and the safety is best.

Specifically, referring to fig. 11 to 13, the first holding mode: the index finger and the middle finger prop against the convex blocks 1012, the guard board 1011 is pressed down by the thumb, and the sampling port is fixed by friction force formed by pressing; the second holding mode: the index finger and the middle finger clamp the convex block 1012 at the lower part, and the sampling port is fixed by the friction force between the convex block 1012 and the index finger and the middle finger; third way of holding: the thumb and the index finger pinch the bump 1012 and the sampling port is fixed by the friction force between the bump 1012 and the thumb and the index finger.

It can be appreciated that in the first holding mode, the bottom of the sampling port is provided with a bump 1012 for the contact of the index finger and the middle finger, and a guard board 1011 suitable for the placement of the thumb is provided, meanwhile, the guard board 1011 can protect the index finger and the middle finger, so that the sampling port can be fixed and the finger can be prevented from being damaged due to puncture error; in the second holding mode, the bottom of the sampling port is provided with a bump 1012 for clamping the index finger and the middle finger, and meanwhile, the guard board 1011 can protect the index finger and the middle finger, so that the sampling port can be well fixed and the fingers can be prevented from being damaged due to puncture errors; under the third mode of holding, the bottom of sampling mouth is equipped with the lug 1012 that supplies thumb and forefinger to hold between the fingers, and simultaneously, backplate 1011 can protect thumb and forefinger, can guarantee like this that the sampling mouth has good fixing and can avoid damaging the finger because of the puncture mistake.

In addition, it can be understood that the sampling port with the straight puncture plug 102 (the axis of the puncture plug 102 is coaxial with the axis of the main body 101, and the axis of the main body 101 is a vertical line), when an accident happens, the puncture of the syringe is perpendicular to the finger, so that the finger is more easily stabbed to form larger injury; compared with a sampling port with a straight puncture plug 102, when the sampling port with the inclined puncture plug 102 (the axis of the puncture plug 102 is obliquely arranged relative to the axis of the main body 101) is unexpected, the puncture finger of the injector is parallel to the finger or forms an acute angle, under the action of the same puncture force, the puncture effect is generated by the action of the puncture force perpendicular to the surface of the finger, the action of the puncture force perpendicular to the surface of the finger is far smaller than the puncture force, the puncture effect is far smaller than the sampling port with the straight puncture plug, and the damage is smaller and safer.

Thus, the above-mentioned pipeline sampling port 100 can improve stability, safety, comfort of use to can adapt to different medical personnel's gripping habits.

In some embodiments, the main body 101 further includes a pipe connection end 1013, the pipe connection end 1013 is disposed on the bump 1012, the pipe connection end 1013 penetrates the bump 1012, and the pipe connection end 1013 is used to connect the external pipe 200.

It should be noted that the tubing connection 1013 is connected to the blood tubing 200 by cyclohexanone (a plastic adhesive), the outer diameter of the blood tubing 200 is the same as the inner diameter of the tubing connection 1013, and the inner diameter (or narrowest portion) of the blood tubing 200 is the same as the narrowest portion of the tubing connection 1013, thereby ensuring that the blood flow portion is not accumulated due to narrowing of the flow path.

In some embodiments, the guard 1011 is provided with a pressing surface 10111 for pressing by a thumb, the pressing surface 10111 is disposed on two sides of the puncture plug 102 along the axial direction of the pipe connection end 1013, and the pressing surface 10111 is provided with a first anti-slip ridge 10112.

In this way, in the first holding manner, the bottom of the protrusion 1012 has a plane wide enough to place the index finger and the middle finger, and the guard 1011 can protect the finger below the guard 1011 from damage due to the puncture error, and the guard 1011 is provided with a pressing surface 10111 suitable for pressing by the thumb and a first ridge 10112 capable of preventing the finger from slipping. Thus, the stability and the comfort of the gripping sampling port can be ensured.

Of course, according to actual needs, the pressing surface 10111 can be far away from the puncture position as far as possible, so that the thumb can be far away from the puncture position of the sampling port as far as possible.

In some embodiments, the bottom surface of the protrusion 1012 may be curved, or the bottom surface may be provided with anti-slip embossments or stud-like protrusions.

In some embodiments, the tab 1012 is provided with a gripping surface 10121 for contact by the index finger and middle finger, and the gripping surface 10121 is provided with a second ridge 10122 that is non-slip.

In addition, in the third holding mode, the guard board 1011 protects fingers, and the bump 1012 can be arranged to have a wider holding position, so that the second convex line 10122 on the bump 1012 can make the holding firmer.

In some embodiments, guard 1011 extends along the periphery of piercing plug 102 to form a polygonal plate (e.g., a square plate) with a cross-sectional area greater than the cross-sectional area of projection 1012 in order to maximize finger protection.

Preferably, the polygonal plate may completely cover the protrusion 1012 and the fingers on both sides of the protrusion 1012 when the protrusion 1012 is gripped by the index finger and the thumb or the middle finger.

In some embodiments, the piercing plug 102 is disposed obliquely toward the one-sided tubing connection end 1013. The sampling port with the oblique puncture plug 102 can reduce damage and is safer.

Referring to fig. 14, it can be understood that when an accident occurs in the sampling port with the straight puncture plug 102, the puncture of the syringe is perpendicular to the finger, so that the finger is more easily stabbed to form a larger injury; compared with the sampling port with the straight puncture plug 102, when the sampling port with the inclined puncture plug 102 is unexpected, the finger can be parallel to the finger or form an acute angle by the puncture of the injector, under the action of the same puncture force, the puncture effect is generated by the action of the puncture force perpendicular to the surface of the finger, the action of the puncture force perpendicular to the surface of the finger is far smaller than the puncture force, the puncture effect is far smaller than the sampling port with the straight puncture plug 102, and the damage is smaller and safer.

In some embodiments, for easy connection, a connection portion 1014 is provided at the center of the main body 101, and the piercing plug 102 is fixed in the connection portion 1014, where the connection portion 1014 may be an open plastic.

Preferably, the puncture plug 102 may be a silicone plug cut from a single piece of silicone, and the silicone plug is engaged into the connecting portion 1014 by thermal deformation.

In some embodiments, the piercing plug 102 is provided with a recessed structure 1021. The mode of adopting the concave structure 1021 on the puncture plug 102 can reduce the puncture distance of the injection needle during sampling, so that the puncture operation is easier.
