Description

Technical Field

[0001] This utility model relates to the field of diluent bottle technology, specifically to a diluent bottle for a plasma POCT biochemical device. Background Technology

[0002] In recent years, the incidence of infertility has increased. According to authoritative data analysis, male and female causes are equally prevalent. In medical institutions examining male infertility, ALT (alanine aminotransferase), Urea (urea), and total protein (TP) in seminal plasma have been verified to be related to fertility. Technological advancements have made point-of-care testing (POCT) increasingly less restricted by location or operator expertise. Its application scenarios have expanded beyond bedside care to include home healthcare, mobile healthcare, field environments, battlefield medicine, and even returning to central laboratory settings. Especially with the continuous maturation of precise quantitative POCT testing systems, particularly the development of microfluidic technology, the use of POCT in laboratories is gradually becoming a reality. Therefore, modern POCT has become synonymous with "on-site," "fast," and "convenient." Simultaneously, while ensuring accurate test results, smaller size has become a development trend for POCT.

[0003] Because many POCT users lack professional knowledge and training, some tests require dilution of samples to a certain factor before testing. Inaccurate dilution can lead to erroneous results. Manually performing these repetitive tasks is labor-intensive and prone to errors. Therefore, an automated, quantitative bottle with automatic dilution replenishment is essential for this type of POCT device. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a diluent bottle for POCT biochemical equipment for plasma processing, in order to solve the problem that in the prior art, due to factors such as the lack of professionalism and training among most POCT users, some tests require adding diluent to the sample and diluting it to a certain factor before testing, and inaccurate dilution factor will lead to incorrect test results.

[0005] A diluent bottle for a plasma POCT biochemical device includes an injection bottle with a cavity inside. An injection rod is slidably mounted inside the cavity. An injection head is installed in a mounting hole at the bottom of the injection bottle and is sleeved on the outside of the injection rod. The top of the injection rod passes through the top of the injection bottle and is slidably connected to a limiting nut located on the outside of the injection bottle. A return spring is provided inside the injection head to reset the injection rod. The cavity is used to contain the diluent. A second replenishment hole communicating with the cavity is provided on one side of the injection head. The injection rod is used to push the diluent in the injection head to flow out through the opening at the bottom of the injection head. The limiting nut is used to control the movement distance of the bottom end of the injection rod inside the injection head, thereby controlling the amount of diluent flowing out of the injection head.

[0006] Furthermore, the top of the injection rod is connected to the output shaft of a linear motor located outside the injection bottle.

[0007] Furthermore, a sealing ring is provided on the outer side of the bottom end of the injection rod.

[0008] Furthermore, the injection rod is divided into a small diameter section, a medium diameter section, and a large diameter section from top to bottom. The diameter of the small diameter section is smaller than that of the medium diameter section, and the diameter of the medium diameter section is smaller than that of the large diameter section. The small diameter section passes through a limiting hole located at the top of the injection bottle, and a limiting nut is installed on the small diameter section. The diameter of the medium diameter section is larger than that of the limiting hole, and a sealing ring is provided on the outer side of the large diameter section.

[0009] Furthermore, an O-ring is provided on the outer side of the injection head.

[0010] Furthermore, a first replenishment hole is provided at the top of the injection bottle.

[0018] like Figures 1-4The illustrated diluent bottle for a plasma POCT biochemical device includes an injection bottle 1 with a cavity inside. An injection rod 2 is slidably mounted inside the cavity. An injection head 3 is installed in the mounting hole 101 at the bottom of the injection bottle 1 and is sleeved on the outside of the injection rod 2. The top of the injection rod 2 passes through the top of the injection bottle 1 and is slidably connected to a limiting nut 201 located on the outside of the injection bottle 1. A return spring 202 is provided inside the injection head 3 to reset the injection rod 2. The cavity is used to contain the diluent. A second replenishment hole 301 communicating with the cavity is provided on one side of the injection head 3. The injection rod 2 is used to push the diluent in the injection head 3 to flow out through the opening at the bottom of the injection head 3. The limiting nut 201 is used to control the movement distance of the bottom end of the injection rod 2 inside the injection head 3, thereby controlling the amount of diluent flowing out of the injection head 3.

[0019] In this embodiment, the second replenishment hole 301 is used to communicate with the cavity, so that the diluent in the cavity is added to the injection head 3 in a timely manner through the second replenishment hole 301; the distance that the injection rod 2 moves along the axial direction of the injection head 3 is controlled by the setting of the limit nut 201, thereby controlling the amount of diluent flowing out of the injection head 3, and controlling the dilution ratio by precisely controlling the amount of diluent flowing out.

[0020] The top of the injection rod 2 is connected to the output shaft of a linear motor located outside the injection bottle 1.

[0021] In this embodiment, the linear motor is a conventional linear motor used to control the periodic sliding of the injection rod 2, thereby enabling the movement of the injection rod 2 and the periodic outflow of the diluent, making the injection of the diluent more automated.

[0022] A sealing ring 203 is provided on the outer side of the bottom end of the injection rod 2. The sealing ring 203 is used to seal the gap between the outer side of the injection rod 2 and the inner wall of the injection head 3.

[0023] In this embodiment, the sealing ring 203 is used for sealing to prevent leakage and ensure that the amount of diluent flowing out from the injection head 3 is more accurate.

[0024] The injection rod 2 is divided into a small diameter section, a medium diameter section, and a large diameter section from top to bottom. The diameter of the small diameter section is smaller than that of the medium diameter section, and the diameter of the medium diameter section is smaller than that of the large diameter section. The small diameter section passes through the limiting hole 104 located at the top of the injection bottle 1. A limiting nut 201 is installed on the small diameter section. The diameter of the medium diameter section is larger than that of the limiting hole 104. A sealing ring 203 is provided on the outer side of the large diameter section.

[0025] In this embodiment, the movement distance of the injection rod 2 can be further limited by the cooperation between the limiting hole 104 and the middle diameter section, so as to accurately control the amount of diluent flowing out.

[0026] An O-ring 302 is provided on the outside of the injection head 3. The O-ring 302 is used to seal the sealing head and the inner wall of the injection bottle 1.

[0027] In this embodiment, the O-ring 302 is used for sealing to prevent leakage and ensure that the amount of diluent flowing out from the injection head 3 is more accurate.

[0028] The top of the injection bottle 1 is provided with a first replenishment hole 103.

[0029] In this embodiment, the first replenishment hole 103 is used to facilitate the replenishment of diluent to the cavity.

[0030] The injection bottle 1 has an upward-facing placement slot 105 on one side. The bottom of the placement slot 105 is connected to the cavity through a through hole 102. A sensor 5 is installed at the bottom of the placement slot 105. A float switch 4 is placed inside the placement slot 105. The float switch 4 is used in conjunction with the sensor 5 to control whether the diluent at the first replenishment hole 103 flows into the cavity.

[0031] In this embodiment, the through hole 102 is used to move the diluent in the cavity into the placement tank 105. The diluent in the placement tank 105 will push the float switch 4 upward. As the diluent in the cavity is used, the float switch 4 will move downward with the liquid level until it reaches the trigger sensor 5, and then the first replenishment hole 103 will start replenishing the liquid.

[0032] Working principle: Diluent is injected into the cavity through the first replenishment hole 103. The diluent flows from the cavity into the injection head 3 and the placement tank 105 through the second replenishment hole 301 and the through hole 102, respectively. As the amount of diluent in the placement tank 105 increases, the float switch 4 moves upward. The height of the injection rod 2 is adjusted by the limit nut 201, thereby adjusting the amount of diluent flowing out of the injection head 3 in a single injection. When the linear motor is started, its output shaft cycles back and forth, driving the injection rod 2 to move. The injection rod 2 pushes a certain amount of diluent out of the injection head 3 at a time. Then, under the action of the linear motor and the spring 202, the injection rod 2 moves upward and returns to its original position, replenishing the injection head 3 with diluent through the second replenishment hole 301. After multiple outputs of diluent, the float switch 4 moves downward to the trigger sensor 5 as the liquid level drops, and the first replenishment hole 103 replenishes the cavity with diluent.

[0033] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention. Clearly, those skilled in the art can make various alterations and modifications to the present invention without departing from its spirit and scope. Thus, if these modifications and modifications of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention also intends to include these modifications and modifications.
