Description

Technical Field

[0001] This invention relates to the field of dispensing technology, and in particular to a negative pressure dispenser for blood products. Background Technology

[0002] As is well known, autologous serum, when drawn blood and left at room temperature, mainly separates into two layers. The top layer consists of red blood cells that sink to the bottom, while the yellow liquid composed of plasma floats to the top. It contains a large number of growth factors and mediators that promote wound healing and cell proliferation, as well as rich nutrients such as vitamin A. This helps with recovery after corneal surgery, alleviates inflammation, and reduces early-stage dry eye syndrome. In addition, platelet-concentrated plasma is made by concentrating only a large number of growth factors effective for wound healing from platelets and then mixing them with a certain amount of plasma for use. Compared with existing autologous serum, it not only has a higher plasma concentration but also allows for precise extraction, promising excellent surgical results.

[0003] Eye drops made from concentrated blood plasma are derived from the patient's own blood, eliminating concerns about rejection or side effects. They provide the patient with appropriate nutrients, especially beneficial in ophthalmic use. They promote corneal regeneration and healing, even for minor corneal wounds. Furthermore, through regenerative factors and anti-inflammatory effects, they alleviate postoperative pain, provide epidermal nutrition, and prevent dry eye syndrome.

[0004] By observing the preparation process of PRP eye drops, after drawing blood from the patient, serum and blood cells were separated using a centrifuge. The resulting serum was then mixed with BBC solution in an appropriate ratio. The preparation process was then confirmed by microfiltration to ensure the absence of impurities and microbial infection in the prepared eye drops. PRP eye drops prepared in this way are basically the same as those used in painless abortions, so they should be refrigerated in principle, and the daily dosage should be refrigerated in small amounts.

[0005] Traditional dispensing methods increase the number of operations due to varying PRP dosages, leading to increased operator fatigue. While automatic sprayers can dilute PRP eye drops, practical difficulties exist. PRP dosages are made from the patient's blood, and once diluted, the path of the eye drops and the injection and discharge points must be disinfected and cleaned. Therefore, it is practically difficult to utilize automatic circulation. The process of diluting PRP eye drops into multiple containers needs to be simplified to reduce operator fatigue and other drawbacks. Summary of the Invention

[0010] Preferably, the number of embedded branch pipes, rubber round pipes, limiting collars and dispensing pipes are all six sets. The six sets of embedded branch pipes, rubber round pipes, limiting collars and dispensing pipes are evenly distributed at the distribution component. The embedded branch pipes are connected to the rubber rings through the rubber round plates. The limiting pressure plate and the rubber rings are connected through the rubber round pipes. The rubber round pipes and the crushing head are connected through the limiting pressure plate. The crushing head is connected to the dispensing pipes through a sealing plug.

[0011] Preferably, an inner ring is rotatably mounted on the inner side of the limiting pressure plate, and an elastic component is slidably sleeved on the surface of the dispensing component, with the two ends of the elastic component respectively abutting against the surfaces of the inner ring and the dispensing component.

This ensures the overall flexibility of the negative pressure distributor and the convenience of operation, and improves the ease of dispensing and preparing the injection liquid, so as to reduce the disadvantage of repeated operation by the operator, which is time-consuming and laborious.

[0020] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution. Example 1:

[0024] Please see Figure 1-5 The present invention provides a technical solution: a negative pressure dispenser for blood products, including a dispensing component 1, a limiting ring 2 welded to the surface of the dispensing component 1, a dispensing tube 3 slidably installed on the inner side of the limiting ring 2, a pagoda head 4 bonded to the surface of the dispensing tube 3, a sealing plug 5 bonded to the end of the dispensing tube 3 away from the pagoda head 4, a sealing membrane 6 bonded to the inner side of the sealing plug 5, the pagoda head 4 being conical in shape, and the surface of the pagoda head 4 slidably installed on the inner side of the limiting ring 2.

[0025] Specifically, the conical pagoda head 4 on the dispensing tube 3 can achieve a more precise assembly effect when it is connected with the limiting collar 2. The sealing plug 5 on the dispensing tube 3 forms a sealing and closing effect, and the sealing film 6 on the sealing plug 5 provides protection when the sealing plug 5 is not punctured by pressure.

[0026] Furthermore, a limiting pressure plate 7 is slidably installed on the surface of the dispensing component 1, and a breaking head 8 is bonded to the surface of the limiting pressure plate 7. The breaking head 8 is in the shape of a pointed tip. A rubber tube 13 is provided between the dispensing component 1 and the limiting pressure plate 7. The rubber tube 13 is used to form a connection between the dispensing component 1 and the limiting pressure plate 7. The pointed tip of the breaking head 8 ensures that when the breaking head 8 is pressed and comes into contact with the sealing film 6 on the sealing plug 5, an effective film breaking effect is formed, so that the breaking head 8 can enter the interior of the sealing plug 5 for docking and assembly.

[0027] Furthermore, a three-way manifold 16 is fixedly mounted on the surface of the distribution component 1. A first control valve 20 and a second control valve 21 are fixedly mounted on the surface of the three-way manifold 16. The function of the first control valve 20 and the second control valve 21 is to ventilate and seal the two ports of the three-way manifold 16. The first control valve 20, the second control valve 21, and the three-way manifold 16 are all common structures in this technical field, and will not be described in detail here.

[0028] Furthermore, an air extraction assembly 19 is bonded to the port of the three-way branch pipe 16, and an injection tube 22 is slidably installed at the end of the three-way branch pipe 16 away from the air extraction assembly 19. When the second control valve 21 is closed and the first control valve 20 is open, the air extraction assembly 19 performs air extraction. When the first control valve 20 is closed and the second control valve 21 is open, liquid can be injected into the three-way branch pipe 16 through the injection tube 22. Example 2:

[0029] Please see Figure 1-5 Based on Embodiment 1, an inner ring 10 can be added. The inner ring 10 is rotatably installed inside the limiting pressure plate 7. An elastic component 11 is slidably sleeved on the surface of the distributing component 1. The two ends of the elastic component 11 are respectively abutted and installed on the surfaces of the inner ring 10 and the distributing component 1. When the limiting pressure plate 7 rotates, the inner ring 10 assists the elastic component 11 in forming a limiting adjustment. And when the limiting pressure plate 7 squeezes and rotates the elastic component 11, the inner ring 10 assists the limiting pressure plate 7 in performing smooth adjustment movement.

[0030] Furthermore, a rubber ring 12 is rotatably mounted on the inner side of the dispensing component 1. The surface of the rubber ring 12 is bonded to the surface of the rubber tube 13. The surface of the rubber tube 13 is slidably mounted on the inner side of the limiting pressure plate 7. When the limiting pressure plate 7 is adjusted upward, the rubber tube 13 can be stored inside it. At the same time, when the limiting pressure plate 7 is rotated, the rubber tube 13 will drive the rubber ring 12 to rotate with the dispensing component 1.

[0031] Furthermore, an auxiliary ring 9 is rotatably mounted on the surface of the limiting pressure plate 7. The function of the auxiliary ring 9 is to assist the limiting pressure plate 7 in having a smooth movement effect when it is rotated and adjusted.

[0032] Furthermore, a positioning head 14 is welded and installed on the surface of the limiting pressure plate 7, and a positioning groove 15 is opened on the inner side of the distributing component 1. The positioning groove 15 and the positioning head 14 on the distributing component 1 are both in an L-shape. When the operator controls the limiting pressure plate 7 to abut against the upper inner side of the distributing component 1, the positioning head 14 on the limiting pressure plate 7 will enter the inner wall of the positioning groove 15 on the distributing component 1. Then the operator rotates the limiting pressure plate 7. At this time, the positioning head 14 on the limiting pressure plate 7 will be adjusted in the L-shape within the positioning groove 15 until the positioning head 14 on the limiting pressure plate 7 is adjusted and positioned inside the distributing component 1. At this time, the limiting pressure plate 7 is pushed by the elasticity of the compressed elastic component 11 to form a positioning position with the upper side of the distributing component 1.

[0033] Furthermore, an embedded branch pipe 17 is fixedly installed at the lower end of the tee branch pipe 16. A rubber disc 18 is bonded to the end of the embedded branch pipe 17 away from the tee branch pipe 16. The surface of the rubber disc 18 is rotatably installed inside the rubber ring 12. When the rubber ring 12 is rotated inside the distribution assembly 1 by the rubber tube 13, the rubber ring 12 will not rotate due to the limiting assembly between the rubber disc 18 and the embedded branch pipe 17, thereby ensuring that the movement of the rubber ring 12 is not restricted when the rubber tube 13 is adjusted.

[0034] Furthermore, the number of embedded branch pipes 17, rubber round pipes 13, limiting collars 2, and dispensing pipes 3 are all six sets. The six sets of embedded branch pipes 17, rubber round pipes 13, limiting collars 2, and dispensing pipes 3 are evenly distributed at the distribution component 1. The embedded branch pipes 17 are connected to the rubber rings 12 through the rubber round plates 18. The limiting pressure plate 7 and the rubber rings 12 are connected through the rubber round pipes 13. The rubber round pipes 13 and the crushing head 8 are connected through the limiting pressure plate 7. The crushing head 8 is connected to the dispensing pipes 3 through the sealing plugs 5. The number of limiting collars 2 and embedded branch pipes 17 can be adjusted to eight, ten, twenty, etc., according to actual needs.

[0035] Furthermore, the contact surfaces of the rubber disc 18 and the rubber ring 12, the contact surfaces of the rubber tube 13 and the limiting pressure plate 7, and the contact surfaces of the rubber ring 12 and the distribution component 1 are all made of rubber. They can be rotated or slidably adjusted while also having a certain sealing performance. This rubber material is a common structure in the medical field for those skilled in the art, and will not be described in detail here.

[0036] Working principle: A negative pressure blood product dispenser, when the liquid needs to be delivered to the dispensing tube 3 through the injection tube 22, the operator first raises the limiting plate 7. At this time, the positioning clip 14 on the limiting plate 7 enters the inner wall of the positioning groove 15 on the dispensing component 1. Then, by rotating the limiting plate 7, the embedded dispensing tube 17 is limited at the positioning groove 15 on the dispensing component 1. Then, after the operator places the six dispensing tubes 3 at the six limiting collars 2 respectively, the operator rotates the limiting plate 7 to reset. At this time, the limiting plate 7 is pushed down at the dispensing component 1 by the elasticity of the compressed elastic component 11. Since the elasticity of the elastic component 11 is greater than the sum of the resistance of the six sealing plugs 5 and the sealing membrane 6, the limiting plate 7 drives the six breaking heads 8 to break the membrane and assemble with the sealing plugs 5 on the six dispensing tubes 3 respectively. After the limiting pressure plate 7 completes the assembly of the crushing head 8 and the sealing plug 5 on the dispensing pipe 3, the operator checks and closes the second control valve 21, and then opens the first control valve 20. The operator controls the air extraction component 19 to go through the three-way branch pipe 16 to the embedded branch pipe 17, and then sucks away the air inside the dispensing pipe 3 through the rubber round pipe 13 and the crushing head 8. At this time, the inside of the dispensing pipe 3 and the three-way branch pipe 16 are in a negative pressure state. Then the operator controls the first control valve 20 to close and the second control valve 21 to open. The operator injects the liquid inside the injection tube 22 to the three-way branch pipe 16 to the embedded branch pipe 17, and then through the rubber round tube 13 and the crusher head 8 to the dispensing tube 3. At this time, due to the negative pressure state inside the dispensing tube 3, the injected liquid can be more fully absorbed and stored.

[0037] Contents or structures not described in detail in this specification are existing technologies known to those skilled in the art, and therefore will not be elaborated upon further.

[0038] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
