[0002] Hemodialysis in nephrology is mainly used for kidney diseases such as chronic renal failure or acute renal injury. When kidney function is impaired and the body cannot remove waste and excess water normally, hemodialysis becomes an important means to maintain the patient's life.

[0003] The existing Chinese patent CN114366097B discloses a hemodialysis sampler for nephrology, including a main body, wherein a guide rod is arranged inside the main body for preventing excessive blood sampling. By arranging a top plate inside the main body and fixing it at a certain position by a fixing seat, the piston of the main body can be pressed to prevent excessive blood sampling from causing discomfort to the patient, and the top plate can be conveniently disassembled and recycled by the snap connection between the hook plate and the holder; by arranging a pad at the lower end of the main body to press against the patient's skin and fixing the upper end of the support by the clamp seat, the elasticity of the spring can be used to buffer the main body by pressing the main body down to prevent the needle from piercing too deeply and causing pain to the patient and reducing the experience effect; by arranging a container at the lower end of the main body connected to the main body, further rotating the rotating plate can drive the sealing block to open the liquid outlet of the main body and press the piston down to store the blood inside the container, which is simple to operate and easy to use to avoid infection.

[0004] The above-mentioned hemodialysis sampler needs to transfer the blood sample into a suitable sampling tube after sampling, so as to facilitate subsequent testing. However, sample contamination may occur during the blood sample transfer process. Utility Model Content

[0007] Preferably, the sampling and liquid dispensing assembly comprises a syringe body and a piston rod, one end of the piston rod is provided with a piston, and the other end of the piston rod is fixedly connected with a round pressure handle.

[0008] Preferably, the one-way absorption component comprises an absorption nozzle and a needle, and the internal limiting rotation of the absorption nozzle is connected to a one-way valve.

[0009] Preferably, the piston rod slides inside the syringe body through a piston limiter, the needle sleeve is fixed to the outside of the absorption nozzle, and the rotation range of the one-way valve is within 90 degrees.

[0010] Preferably, the limit frame assembly includes a connecting pipe, one end of which is fixedly connected to the limit frame body; the opening and closing assembly includes a valve ball core, one side of the valve ball core is fixedly connected to a connecting valve stem, and the outer side of the connecting valve stem is also fixedly connected to a handle.

[0011] Preferably, the valve ball core is rotationally locked in the connecting pipe in a limited position, and the limiting edge is slidably locked in the limiting frame body.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the sampling tube body is limitedly slidably embedded in the limiting frame assembly by the limiting edge, and blood sampling can be performed through the sampling liquid separation assembly and the one-way absorption assembly. After the blood sample is collected inside the sampling liquid separation assembly, the opening and closing assembly is opened, and the sampling liquid separation assembly is controlled to work so that the blood sample can be pushed into the sampling tube body.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a hemodialysis sampler for nephrology, comprising: a sampling and liquid separation mechanism 1, comprising a sampling and liquid separation component 11, a one-way absorption component 12 embedded in the sampling and liquid separation component 11, a limiting frame component 13 fixedly connected to the sampling and liquid separation component 11, and an opening and closing component 14 is also arranged in the middle of the limiting frame component 13; a sampling tube mechanism 2, comprising a sampling tube body 21, and a limiting edge 22 fixedly connected to the sampling tube body 21, and the limiting edge 22 can be slidably embedded in the limiting frame component 13;

[0022] Among them, the sampling tube body 21 is limited and slidably embedded in the limiting frame assembly 13 through the limiting edge 22, and blood sampling can be performed through the sampling and liquid separation assembly 11 and the one-way absorption assembly 12. After the blood sample is collected inside the sampling and liquid separation assembly 11, the opening and closing assembly 14 is opened, and then the sampling and liquid separation assembly 11 is controlled to work so that the blood sample can be pushed into the sampling tube body 21.

[0023] Specifically, the sampling and liquid separation component 11 includes a syringe body 111 and a piston rod 112 . A piston 113 is provided at one end of the piston rod 112 , and a round pressure handle 114 is fixedly connected to the other end of the piston rod 112 .

[0024] Specifically, the one-way absorption component 12 includes an absorption nozzle 121 and a needle 122 , and the internal limit rotation of the absorption nozzle 121 is connected to a one-way valve 123 .

[0025] Specifically, the piston rod 112 is limited and slidable inside the syringe body 111 by the piston 113, the needle 122 is sleeved and fixed on the outside of the absorption nozzle 121, and the rotation range of the one-way valve 123 is within 90 degrees;

[0026] The rotation range of the one-way valve 123 within 90 degrees can avoid the situation where the one-way valve 123 cannot be closed.

[0027] As can be seen from the above, the sampling tube body 21 is inserted into the limit frame assembly 13 by sliding the limit edge 22, and then the needle 122 is inserted into the blood to be dialyzed. Pulling the round pressure handle 114 can make the piston rod 112 drive the piston 113 to move. The movement of the piston 113 will open the one-way valve 123, and the blood will be sucked into the syringe body 111. When the sampling is completed, pushing the round pressure handle 114 can close the one-way valve 123.

[0028] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the limit frame assembly 13 includes a connecting pipe 131, one end of which is fixedly connected to the limit frame body 132; the opening and closing assembly 14 includes a valve ball core 141, one side of the valve ball core 141 is fixedly connected to a connecting valve stem 142, and the outer side of the connecting valve stem 142 is also fixedly connected to a handle 143.

[0029] Specifically, the valve ball core 141 is locked in the connecting pipe 131 in a limited rotation manner, and the limit edge 22 is locked in the limit frame body 132 in a slidable manner.

[0030] As can be seen from the above, rotating the handle 143 causes the connecting valve stem 142 to drive the valve ball core 141 to rotate, and the rotation of the valve ball core 141 can open the connecting pipe 131. At this time, pushing the round pressure handle 114 will push the blood sample in the syringe body 111 into the sampling tube body 21. When the sampling tube body 21 is full, the full sampling tube body 21 is removed and replaced with a new sampling tube body 21, which can facilitate the staff to perform multiple equal sampling.
