Description

Technical Field

[0001] This utility model relates to the technical field of blood filtration and collection devices, and in particular to a blood filtration and collection device for a cattle and sheep blood drawing operating table. Background Technology

[0002] In the fields of animal husbandry and veterinary medicine, blood collection from large livestock such as cattle and sheep is a common operation used for disease diagnosis, health monitoring and scientific research. The cattle and sheep blood collection station is a blood collection device specially designed for cattle and sheep, which aims to improve the efficiency and safety of the blood collection process. The station consists of a fixing device, a placement box, a collection bucket and lockable wheels.

[0003] The placement box is used to hold blood collection bottles. After collection, blood is generally stored in these bottles, which are sealed with rubber stoppers. During blood testing, the blood needs to be filtered. Blood filtration detects pathogens, toxins, or other abnormal components in the blood, obtaining sterile blood products for research or medical use. Traditional filtration methods use filters, but the flow rate of the blood lacks control. If the flow rate is too fast, incomplete filtration may occur, affecting the accuracy of the test results. Therefore, a blood filtration and collection device for bovine and ovine blood collection is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A blood filtration and collection device for a cattle and sheep blood drawing operating table includes a support frame. A filter element is fixedly attached to the surface of the support frame via a fastener. The filter element includes a puncture needle, with a drainage tube connected to the bottom end of the puncture needle. A polyethersulfone membrane filter is connected to the end of the drainage tube. A funnel cover is attached to the bottom end of the polyethersulfone membrane filter and is fastened to the surface of the funnel. A collection bag is connected to the bottom end of the funnel. A speed regulating element is provided at the end of the polyethersulfone membrane filter pipe.

[0007] Preferably, the polyethersulfone membrane filter consists of two tube ends, a filter housing end, and a polyethersulfone membrane core. The polyethersulfone membrane core is a commonly used filter membrane material with good chemical stability and biocompatibility, which can achieve better blood filtration effect.

[0008] Preferably, the fastener includes a buckle, which is fastened to the end surface of the polyethersulfone membrane filter. A collar is connected to the right side of the buckle and is fitted onto the support surface. A locking bolt is inserted into the right side of the collar through a threaded hole. When the polyethersulfone membrane filter is fastened inside the buckle, the suspension height of the polyethersulfone membrane filter can be freely changed by moving the collar on the support surface.

[0009] Preferably, the buckle has a U-shaped cross-section and a rubber end on its inner wall. The opening diameter of the rubber end gradually decreases from the inside to the outside. The U-shaped design of the buckle facilitates the side insertion and embedding of the polyethersulfone membrane filter, ensuring the ease of installation of the polyethersulfone membrane filter.

[0010] Preferably, the speed regulating component includes a mounting box, the side of which has a slot adapted to the end of the polyethersulfone membrane filter pipe, and a scale strip is inserted through a through groove on the left side of the mounting box, with a pressure plate connected to the end of the scale strip. The pressure plate is pushed by moving the scale strip, which can change the blood flow rate in the polyethersulfone membrane filter pipe at any time.

[0011] Preferably, the pressure plate has a V-shaped groove design on its inner side, and a rubber block end is provided at the center of the groove. The rubber block end in the groove can squeeze the pipe of the polyethersulfone membrane filter as the scale bar moves, thereby controlling the filtration flow rate of the polyethersulfone membrane filter.

[0012] Preferably, the mounting box has through holes on both sides with insertable pins, and each pin consists of a trapezoidal locking block end and a column end. A spring is sleeved on the surface of the pin, and the scale bar has several limiting grooves that are adapted to the trapezoidal locking block end of the pin. After the scale bar is adjusted, the spring force can push the pin, thereby controlling the trapezoidal locking block end of the pin to engage in the limiting groove of the scale bar, ensuring the stability of the scale bar after adjustment.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting up a speed regulating component, the surface of the polyethersulfone membrane filter pipe is squeezed. Compared with the traditional structure, this device controls the scale strip to push the pressure plate by pressing the scale strip, so that the pressure plate applies pressure to the surface of the polyethersulfone membrane filter pipe, thereby adjusting and changing the blood flow rate in the polyethersulfone membrane filter pipe, thus ensuring the filtration effect of the polyethersulfone membrane filter, preventing filter blockage, protecting blood components, ensuring detection accuracy, and improving detection efficiency to a certain extent.

[0015] 2. By setting up fixing parts, the polyethersulfone membrane filter can be quickly suspended and installed. This device embeds the polyethersulfone membrane filter into the U-shaped groove of the buckle. The rubber end on the inner side of the buckle can wrap around the surface of the polyethersulfone membrane filter under pressure, ensuring the stability of the polyethersulfone membrane filter suspension installation. The polyethersulfone membrane filter and the buckle are connected by a snap-fit ​​method, which can quickly assemble the polyethersulfone membrane filter. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4A blood filtration and collection device for a cattle and sheep blood drawing operating table includes a support 1. A filter element 3 is fixedly attached to the surface of the support 1 by a fixing member 2. The filter element 3 includes a puncture needle 31. A drainage tube 32 is connected to the bottom end of the puncture needle 31, and a polyethersulfone membrane filter 33 is connected to the end of the drainage tube 32. A funnel cover 34 is connected to the bottom end of the polyethersulfone membrane filter 33, and the funnel cover 34 is snapped onto the surface of a funnel 35. A collection bag 36 is connected to the bottom end of the funnel 35. A speed regulating member 4 is provided at the pipe end of the polyethersulfone membrane filter 33.

[0024] The polyethersulfone membrane filter 33 consists of two tube ends, a filter housing end, and a polyethersulfone membrane core.

[0025] The fastener 2 includes a retaining ring 21, which is fastened to the tube end surface of the polyethersulfone membrane filter 33. A collar 22 is connected to the right side of the retaining ring 21 and is sleeved on the surface of the bracket 1. A locking bolt 23 is inserted into the right side of the collar 22 through a threaded hole.

[0026] The buckle 21 has a U-shaped cross-section and a rubber end on its inner wall. The diameter of the opening at the rubber end gradually decreases from the inside to the outside.

[0027] The speed regulating component 4 includes a mounting box 41. The mounting box 41 has a slot on its side that is adapted to the pipe end of the polyethersulfone membrane filter 33. A scale strip 42 is inserted through a through slot on the left side of the mounting box 41, and a pressure plate 43 is connected to the end of the scale strip 42.

[0028] The inner side of the pressure plate 43 has a V-shaped groove design, and a rubber block end is set at the center of the groove of the pressure plate 43.

[0029] The mounting box 41 has a locking shaft 44 inserted through the through holes on the left and right sides. The locking shaft 44 is composed of a trapezoidal locking block end and a column end. A spring 45 is sleeved on the surface of the locking shaft 44. The scale bar 42 has several limiting grooves that are adapted to the trapezoidal locking block end of the locking shaft 44.

[0030] The polyethersulfone membrane filter 33 is equipped with a polyethersulfone membrane core. The polyethersulfone membrane core is a commonly used filter membrane material with good chemical stability and biocompatibility, and is suitable for filtering blood and other biological fluids. After the polyethersulfone membrane filter 33 is snapped into the buckle 21, it can move on the surface of the support 1 through the collar 22, and the suspension height of the polyethersulfone membrane filter 33 can be freely changed. After the collar 22 is adjusted, the locking bolt 23 can be turned to control the shaft end of the locking bolt 23 to abut against and squeeze on the surface of the support 1, so as to ensure the stability of the suspension of the polyethersulfone membrane filter 33.

[0031] The U-shaped structure design of the buckle 21 facilitates the side insertion and embedding of the polyethersulfone membrane filter 33, ensuring the ease of installation. The rubber end of the inner wall of the buckle 21 can abut against and fit against the surface of the polyethersulfone membrane filter 33. The rubber end can deform under pressure, effectively increasing the friction of the polyethersulfone membrane filter 33 installed in the buckle 21, ensuring the stability of the installation. The mounting box 41 has an opening on one side of the slot, through which the mounting box 41 can be fastened to the pipe surface of the polyethersulfone membrane filter 33. The pressure plate 43 can be pushed by moving the scale strip 42, which can change the blood flow rate in the pipe of the polyethersulfone membrane filter 33 at any time.

[0032] When the pressure plate 43 abuts against the surface of the polyethersulfone membrane filter 33 pipe, the V-shaped groove of the pressure plate 43 can fit and conform to the surface of the pipe. The rubber block end in the groove can squeeze the pipe of the polyethersulfone membrane filter 33 along with the movement of the scale strip 42, thereby controlling the filtration flow rate of the polyethersulfone membrane filter 33. An appropriate flow rate can ensure that impurities and pathogens in the blood are effectively filtered. If the flow rate is too fast, larger particles or impurities in the blood may clog the filter, causing the polyethersulfone membrane filter 33 to fail. An appropriate flow rate can reduce the risk of clogging and extend the service life of the polyethersulfone membrane filter 33. An excessively fast flow rate may damage cells and other components in the blood and affect the normal function of the blood. An appropriate flow rate can reduce damage to blood components and maintain the integrity of the blood. In addition, an exhaust valve is provided on the right side of the top of the collection bag 36, which can be used for exhaust operation inside the collection bag 36.

[0033] When the scale bar 42 moves, the inner wall of the limiting groove of the scale bar 42 can squeeze the trapezoidal locking block end of the locking shaft 44. The locking shaft 44 is compressed, which can compress the spring 45. After the scale bar 42 has moved and adjusted, the elastic force of the spring 45 can push the locking shaft 44, thereby controlling the trapezoidal locking block end of the locking shaft 44 to engage in the limiting groove of the scale bar 42, ensuring the stability of the scale bar 42 after adjustment. The limiting groove design on the surface of the scale bar 42 allows the pressure of the pressure plate 43 on the polyethersulfone membrane filter 33 pipeline to be adjusted in multiple levels.

[0034] Working principle: According to the appendix Figure 1 With appendix Figure 3As shown, during use, the polyethersulfone membrane filter 33 is built into the buckle 21 and the position of the polyethersulfone membrane filter 33 is adjusted by moving the collar 22 on the surface of the support 1. After adjustment, the locking bolt 23 is rotated to control the shaft end of the locking bolt 23 to abut against the surface of the support 1, ensuring the stability of the collar 22 after adjustment. During blood filtration, the puncture needle 31 is inserted through the rubber stopper of the blood collection bottle. At this time, the blood machine enters the drainage tube 32 through the puncture needle 31, so that the blood enters the polyethersulfone membrane filter 33. The polyethersulfone membrane in the polyethersulfone membrane filter 33 can filter the blood. After filtration, the blood drips into the funnel 35 after passing through the central pipe of the lid 34. The funnel 35 guides and collects the blood, so that the blood can flow into the collection bag 36 for transfer and storage.

[0035] Secondly, according to the appendix Figure 4 As shown, the mounting box 41 can be snapped on at any position in the upper and lower pipes of the polyethersulfone membrane filter 33. The illustration is only an example and does not represent the final installation position of the speed regulating component 4. The grooves on the surface of the scale bar 42 correspond to multiple preset blood flow rates. By pressing the scale bar 42, the scale bar 42 moves and pushes the pressure plate 43 to move. The pressure plate 43 controls the pressure on the pipes at any position in the upper and lower parts of the polyethersulfone membrane filter 33, thereby controlling and changing the flow rate in the pipes. After the scale bar 42 is pushed and adjusted, the elastic force of the spring 45 pushes the locking shaft 44 to move, controlling the locking block end of the locking shaft 44 to engage with the groove on the surface of the scale bar 42, thereby completing the custom flow rate adjustment.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
