Description

Technical Field

[0001] The present invention relates to the field of automation, and particularly to a needle leakage detection device for blood collection needles. Background Art

[0002] A blood collection needle is a device used to collect blood samples during medical examinations. It generally consists of a tube stopper puncture needle, a catheter, and a venous puncture needle. Blood collection is also one of the essential items during physical examinations or treatments in hospitals.

[0003] During the production process of blood collection needles, due to the extremely small size of the needle cores in the blood collection needles, there are inevitably problems of missing needles or needle leakage when arranging the needles in the mold. To ensure product quality, each blood collection needle has to be inspected before leaving the factory to remove the defective products with missing needles. The existing needle leakage inspection relies entirely on visual inspection by human eyes. The inspectors must be young and have good eyesight. Even so, good lighting is required. Neither strong light nor weak light is acceptable. Strong light is too dazzling and weak light is not clear enough. It must be carried out in an environment with scattered light on sunny days. Therefore, the production efficiency is very low, and the labor intensity of workers is increased. There is currently no good detection method.

[0004] In response to this situation, some enterprises use workers to hold magnets for adsorption detection. Although the efficiency has been improved to some extent, it still belongs to manual operation and the degree of automation is low. Summary of the Invention

[0005] The purpose of the present invention is to provide a needle leakage detection device for blood collection needles to realize automatic operations for a series of actions such as feeding, detection, rejection, and discharging, without manual intervention and with high efficiency.

The guiding component is located above the turntable and does not rotate with the turntable, and the guiding component is synchronously located above the conveying component. The elastic magnetic heads are assembled on the turntable and rotate with the turntable. The elastic magnetic heads move downward to adsorb the blood collection needles with needles on the conveying component after contacting the guiding component, and rise after moving away from the guiding component. The adsorbed blood collection needles with needles fall onto the qualified product discharging component below.

[0007] Preferably, the guiding component includes a mounting post and a guiding strip. The mounting post passes through the hollow rotating platform and is fixed on the cabinet, and the upper end fixes the guiding strip through a connecting plate. The guiding strip is in a semi-circular ring structure, with a thick middle and thin ends.

[0008] Preferably, the elastic magnetic suction head includes a guide post, a mounting plate, a plurality of magnets, and a limiting plate. The guide post is fixed on the turntable in cooperation with a guide sleeve, and the lower part of the guide post passes through the turntable and fixes the mounting plate. A plurality of magnets are fixed on the back of the mounting plate. A limiting plate is arranged above the guide post, and at the same time, a spring is sleeved on the guide post, and both ends of the spring abut against the limiting plate and the guide sleeve respectively.

[0009] Preferably, a cover cylinder is fixed at the bottom of the turntable to cover the outside of the magnets.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0016] A blood collection needle leakage detection device provided by the present invention realizes the detection of blood collection needle leakage, and its structure is as Figure 1 shown, including a cabinet 1, a conveying component 2 installed on the cabinet to realize the conveying of blood collection needles, a feeding component 3 located at one end of the conveying component, a waste discharging component 4 located at the other end of the conveying component, a detection component 5 located on the side of the conveying component, and a qualified product discharging component 6 located below the detection component.

[0017] Specifically, the conveying component is a belt conveyor, with baffles 21 provided on both sides. The feeding component is erected at one end of the feeding component, and it can be in various structural forms, such as a hopper type ( Figure 1 the structure in), or a lifting type feeding structure.

[0018] Since the materials are stacked on the conveyor belt after being fed by the feeding component, in order to facilitate the accuracy of subsequent detection, a leveling plate 7 is also provided on the conveying component, which is erected between the two side plates and located between the feeding component and the detection component. The leveling plate levels the blood collection needles stacked on the conveyor belt, making them disperse on the belt for subsequent adsorption.

[0019] The detection component is a magnetic adsorption structure during rotation, and its specific structure is as Figures 2 - 3 shown, including a turntable 51, a hollow rotating platform 52 for driving the turntable to rotate, elastic magnetic heads 53 installed at equal intervals on the circumference of the turntable, and a guiding component 54. The turntable is fixed to the cabinet in cooperation with the hollow rotating platform, and one side of the turntable is located above the conveyor belt. The structure of the turntable can be circular or the shape in the figure, and the hollow rotating platform is driven to rotate by a motor 55.

[0020] The elastic magnetic head is movably assembled on the turntable, and its structure includes a guide post 531, a mounting plate 532, a plurality of magnets 533 and a limiting plate 534. The guide post is fixed to the turntable in cooperation with a guide sleeve 535, and the guide post can move up and down in the guide sleeve. The lower part of the guide post passes through the turntable and is fixed with a mounting plate, and a plurality of magnets are fixed on the back of the mounting plate. A limiting plate is fixed above the guide post, and at the same time, a spring (not shown in the figure) is sleeved on the guide post. The two ends of the spring abut against the limiting plate and the guide sleeve. In the free state of the spring, the guide post drives the magnet to lift, and when an external force is applied above to compress the spring, the guide post drives the magnet to descend.

[0021] To achieve the adsorption and release of the blood collection needle, a cover cylinder 56 is fixed on the back of the turntable to wrap the lower part of the elastic magnetic suction head. When the magnet moves down and fits the bottom surface of the cover cylinder, the magnetism is enhanced, thus realizing the adsorption of the blood collection needle. When the magnet rises, the magnetism weakens, and the blood collection needle on the bottom surface of the cover cylinder loses the adsorption force and drops into the qualified product blanking component below.

[0022] The guiding component includes a mounting post 541 and a guiding strip 542. The mounting post passes through the hollow rotating platform and is fixed on the cabinet, and the guiding strip is fixed at the upper end through a connecting plate 543. The guiding strip is located above the turntable and does not rotate with the turntable. At the same time, the guiding strip is also located above the conveying component. Specifically, the guiding strip is in a semi-circular ring structure, showing a transition form with a thicker middle and thinner ends. When the elastic magnetic suction head rotates with the turntable to the guiding strip, due to the increase in the thickness of the guiding strip, the guide post of the elastic magnetic suction head gradually moves down, and the magnet gradually fits the bottom surface of the cover cylinder, thereby adsorbing the qualified blood collection needles on the conveying component. As the turntable continues to rotate, the guide post of the elastic magnetic suction head gradually rises, the magnet moves away from the bottom surface of the sleeve, the adsorption force disappears, and the blood collection needle drops.

[0023] The qualified product blanking component includes a blanking plate 61 and a receiving box 62. The blanking plate is inclined and arranged below the turntable, and baffle strips 63 are provided on both sides. The receiving box is located directly below the lower end of the blanking plate. The dropped qualified blood collection needles fall along the inclined blanking plate into the receiving box to complete automatic blanking.

[0024] For unqualified products, since they have no needles, they will not be adsorbed, so they continue to move forward along the conveying component and fall into the waste blanking component at the end. The waste blanking component includes a blanking hopper 41 installed at the end of the conveying component and a waste box 42 located below the blanking hopper.

[0025] A blood collection needle missing needle detection device disclosed by the present invention has a simple structure, can automatically detect the missing needles of blood collection needles, and has high efficiency.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
