Description

Technical Field

[0001] This utility model belongs to the field of medical device disinfection equipment technology, specifically relating to an automatic disinfection micro-volume blood collection tube sterilization box. Background Technology

[0002] Micro-blood collection tubes, also known as capillary blood collection tubes or peripheral blood collection tubes, are used in clinical medical institutions to collect blood from the fingertips, heels, and other extremities of patients (especially infants and young children). They are typically made of glass or plastic, with an extremely fine diameter and equipped with corresponding measurement scales to achieve quantitative collection of minute amounts of blood, and have wide applications in the field of clinical testing.

[0003] Conventional micro-volume blood collection tubes are typically stored in bulk using tubular packaging, with each tub usually containing hundreds of tubes and equipped with corresponding latex pipette tips. This storage method facilitates large-scale transportation and storage to some extent. In actual operation, one end of the micro-volume blood collection tube needs to be connected to a rubber pipette tip, utilizing capillary action or negative pressure to achieve liquid aspiration and drainage.

[0004] However, due to the thinness and fragility of the micro-blood collection tubes, existing storage and retrieval methods have certain limitations in practical applications. Firstly, when retrieving a single tube from a full container, uneven force or a tipping of the plastic container can easily cause the tube to break or slip out, affecting work progress, contaminating the tube, or wasting it. Secondly, because medical personnel wear latex gloves, opening the container to retrieve a single tube hinders rapid blood collection. Furthermore, the open handling process of micro-blood collection tubes easily exposes remaining tubes to the external environment (opening and closing the cap is generally inconvenient, and once opened, it's rarely closed again), increasing the probability of contamination. If this contaminated tube comes into contact with a patient's wound, it can easily cause infection (especially in infants and young children). Additionally, the storage method for latex pipette tips is not conducive to the simultaneous and orderly management of both tubes and tips. Therefore, existing micro-blood collection tube storage methods still have room for improvement in ensuring sterility during sampling, ease of operation, and portability. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an automatic disinfection micro-volume blood collection tube sterilization box. By combining a non-contact triggering mechanism with dynamic sterilization logic, the risk of biological contamination of micro-volume blood collection tubes during storage and distribution is reduced, and the pertinence of the sterilization process is improved, as well as the ease of operation and portability for medical personnel.

[0006] To solve the above-mentioned technical problems, embodiments of this utility model provide an automatic disinfection micro-volume blood collection tube sterilization box, including an outer shell assembly, a storage mechanism, a dispensing mechanism, and a sterilization mechanism. The outer shell assembly includes a base, a supporting side plate, a top cover, and a front panel. The base is connected to the supporting side plate, and the top cover covers the top of the supporting side plate. The lower part of the front panel is provided with a downwardly angled discharge chute. The storage mechanism is located inside the upper part of the outer shell assembly and includes an inclined storage base plate and limiting sidewalls located on both sides of the storage base plate. The dispensing mechanism is installed at the end of the storage base plate and includes a rotating shaft, a dispensing roller, and a stepper motor. The dispensing roller is fixedly sleeved on the rotating shaft, and the output end of the stepper motor is connected to the rotating shaft through a reduction gear set. The sterilization mechanism includes a first sterilization group and a second sterilization group. The first sterilization group is installed on the top of the storage mechanism, and the second sterilization group is installed on the inner top wall of the discharge chute.

[0007] It also includes a sensing linkage mechanism, which includes a sensing probe and a mounting bracket. The sensing probe is fixed above the discharge chute by the mounting bracket and is connected to a stepper motor.

[0008] The feeding roller has a semi-circular arc receiving groove axially formed on its cylindrical surface, and the inner diameter of the semi-circular arc receiving groove matches the outer diameter of the vacuum blood collection tube.

[0009] The dispensing mechanism further includes a limiting brush group, which is fixedly disposed at the end edge of the storage base plate and contacts the outer surface of the dispensing roller.

[0010] The first sterilization group includes multiple longitudinally arranged ultraviolet lamps, each with a quartz protective tube on the outside. The second sterilization group includes transversely arranged ultraviolet lamp beads.

[0011] The sterilization mechanism further includes a reflective backplate, which is disposed on the inner wall surface of the outer casing assembly and is made of mirror stainless steel.

[0012] The support side plate is provided with a heat dissipation grille, and an air filter is provided inside the heat dissipation grille.

[0013] The base has anti-slip feet with a suction cup structure at the bottom.

[0014] The bottom of the discharge chute is provided with a buffer ramp, the surface of the buffer ramp is provided with anti-slip texture, and the outlet of the discharge chute is provided with a flexible curtain composed of multiple overlapping light-blocking films.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0016] This invention reduces direct contact between hands and remaining blood collection tubes in the container through a dispensing mechanism, improving the reliability of aseptic operation. Medical personnel can obtain a small amount of blood collection tubes simply by looking below the dispensing chute, eliminating the risk of cross-infection caused by direct contact and improving the safety of the medical operating environment. By setting a first sterilization group and a second sterilization group on the top of the storage mechanism and the inner top wall of the dispensing chute, a complete sterilization path from static storage to dynamic dispensing is constructed. Combined with the diffuse reflection effect of the reflective backplate, dead angles of irradiation on the surface of the blood collection tubes are eliminated, significantly enhancing the uniformity of the sterilization effect. The entire operation does not require reaching deep into the container to grab the tubes, saving time and reducing contact with the remaining small amount of blood collection tubes and contamination from prolonged periods without a lid, thus improving the convenience of aseptic operation.

[0025] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1 , Figure 2As shown, this embodiment of the invention provides an automatically sterilized micro-volume blood collection tube sterilization box, applicable to medical testing departments for the storage, distribution, and real-time sterilization of vacuum blood collection tubes. This embodiment improves the dispensing transmission structure and ultraviolet irradiation path of the sterilization box, enabling non-contact operation and all-around dynamic sterilization.

[0027] An automatically sterilized micro-volume blood collection tube sterilization box includes an outer shell assembly 1, a storage mechanism 2, a dispensing mechanism 3, and a sterilization mechanism 4. The outer shell assembly 1 includes a base 101, supporting side plates 102, a top cover 103, and a front panel 104. The base 101 is connected to the supporting side plates 102, and the top cover 103 covers the top of the supporting side plates 102. The lower part of the front panel 104 has a downwardly angled discharge channel 107. In this embodiment, the base 101 adopts a rectangular plate structure, with vertically upward supporting side plates 102 at its four corners. The supporting side plates 102 are fastened to the base 101 by hexagonal socket head cap screws. The top cover 103 covers the top of the supporting side plates 102, forming a closed internal chamber. The front panel 104 is installed on the front side of the two supporting side plates 102, and a downwardly angled discharge slide 107 is provided at the bottom of the panel. The end of the discharge slide 107 extends to the outside of the outer shell assembly 1 for medical personnel to take blood collection tubes.

[0028] In this embodiment, four anti-slip feet 105 are installed on the bottom of the base 101. The anti-slip feet 105 adopt a suction cup structure to increase the stability of the entire device on the table. A heat dissipation grille 106 is provided on the side of the outer shell assembly 1. An air filter is installed on the inner side of the heat dissipation grille 106 to maintain internal air circulation and prevent dust from entering.

[0029] The discharge chute 107 is configured as a buffer ramp with a slope less than that of the storage base plate 201. The surface of the buffer ramp is provided with anti-slip texture. A flexible baffle is provided at the outlet of the discharge chute 107. The flexible baffle is composed of multiple overlapping light-blocking films to block internal ultraviolet rays from directly irradiating the external space.

[0030] The storage mechanism 2 is located inside the upper part of the outer shell assembly 1, and includes an inclined storage base plate 201 and limiting sidewalls 202 on both sides of the storage base plate 201. The storage base plate 201 is fixed between the supporting sidewalls 102 by a bracket. The storage base plate 201 has an angle of 15° to 25° with the horizontal plane, and the vacuum blood collection tube is guided to slide downward by gravity. A flexible silicone pad is attached to the surface of the storage base plate 201 to reduce the impact force when the blood collection tube slides down. An adjustable slider can also be provided on the limiting sidewalls 202. By moving the position of the adjustable slider, the distance between the two limiting sidewalls 202 can be changed to accommodate vacuum blood collection tubes of different lengths. In this embodiment, a latex suction tip storage box 203 is also provided on the inner wall of the storage mechanism 2. The bottom of the latex suction tip storage box 203 is an elastic mesh bag. The latex suction tip is stored and collected in the latex suction tip storage box 203 and sterilized together with the micro-blood collection tube in the first sterilization group. In addition, the top of the storage unit 2 is provided with an opening for bulk delivery of vacuum blood collection tubes.

[0031] The dispensing mechanism 3 is installed below the end of the storage base plate 201 and includes a rotating shaft 301, a dispensing roller 302, and a stepper motor. A semi-circular arc receiving groove is formed axially on the cylindrical surface of the dispensing roller 302, and the inner diameter of the semi-circular arc receiving groove matches the outer diameter of the vacuum blood collection tube. Both ends of the rotating shaft 301 are connected to the support side plate 102 via bearing seats. The body of the stepper motor is fixed to the inner side of the support side plate 102, and the output shaft of the stepper motor is connected to the rotating shaft 301 via a gear set. The rotation speed of the dispensing roller 302 can be precisely adjusted by adjusting the gear transmission ratio.

[0032] In this embodiment, the sorting mechanism 3 further includes a limiting brush group, which is fixed to the end edge of the storage base plate 201. The brush bristles of the limiting brush group contact the outer circumferential surface of the feeding roller 302 to prevent blood collection tubes from entering the sorting area (not shown in the figure) that are not in the target slot.

[0033] The sterilization mechanism 4 includes a first sterilization group 401, a second sterilization group 402, and a reflective backplate 403. The first sterilization group 401 is installed on top of the storage mechanism 2 and includes multiple longitudinally arranged ultraviolet lamps. Each ultraviolet lamp has a quartz protective tube, which is fixed to the inside of the top cover 103 by clamps. The second sterilization group 402 includes transversely arranged ultraviolet lamp beads, installed above the outlet of the discharge chute 10710, to circumferentially irradiate the passing vacuum blood collection tubes. The reflective backplate 403 is made of mirror-finished stainless steel with a polished surface. The reflective backplate 403 is fixed to the inner wall of the outer casing assembly 1, and its installation angle is perpendicular to the axis of the ultraviolet lamps, increasing the light coverage.

[0034] The sensing linkage mechanism 5 includes a sensing probe 501 and a mounting bracket 502. The sensing probe 501 is fixed above the discharge slide 107 via the mounting bracket 502, forming a fan-shaped detection area. The sensing probe 501 is connected to the electrical input terminal of the stepper motor via a signal transmission cable. When the sensing probe 501 detects an external obstruction signal, it triggers a power component to drive the feeding roller 302 to rotate by a preset angle. The sensing linkage mechanism 5 may also include a delay protection circuit, which is located between the sensing probe 501 and the power component, and is used to set the cooling time after a single trigger.

[0035] The working principle of this utility model is as follows:

[0036] First, medical staff insert a batch of blood collection tubes through the opening below the top cover 103. Under the action of gravity, the blood collection tubes slide down along the flexible silicone pad layer of the storage base plate 201 and are blocked above the distribution area by the limiting brush group.

[0037] Second, when it is necessary to take a blood collection tube, the medical staff places their hands in the sensing area of ​​the sensing probe 501 below the front panel 104. The trigger signal generated by the sensing probe 501 drives the stepper motor to run through the signal transmission cable. The stepper motor drives the feeding roller 302 to rotate through the reduction gear set. The semi-circular receiving groove of the feeding roller 302 carries a blood collection tube and rotates downward.

[0038] Third, during the rotation of the feeding roller 302, the blood collection tube enters the discharge chute 107. At this time, the first sterilization group 401 and the second sterilization group 402 of the sterilization mechanism 4 enhance the irradiation intensity. After passing through the annular ultraviolet lamp array, the blood collection tube completes surface sterilization and passes through the flexible curtain to reach the end of the discharge chute 107 for medical staff to use.

[0039] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
