Description

Technical Field

[0001] The invention relates to the technical field of blood collection tube storage, in particular to an automatic micro-blood collection tube supplier. Background Art

[0002] Micro blood collection pipettes are commonly used tools for collecting blood in hospitals. The existing micro blood collection pipette structure includes a capillary pipette, a pipette joint, a pipette and a dripper. The capillary pipette and the pipette joint are integrated, the pipette and the dripper are connected, and one end of the pipette is sleeved on the tail of the pipette joint. Instructions for use: Hold the micro blood collection pipette with your hand, put the end of the capillary pipette into the blood to be measured, and the blood will be automatically sucked into the capillary pipette until the blood rises to the top of the capillary pipette. The automatic full suction time is no more than 2s, and then the end of the capillary pipette is gently touched on the inner wall of the container (test tube or blood sample cup, etc.), and the dripper is squeezed with your fingers to discharge the blood in the capillary into the container. Micro blood collection pipettes sold in commercial boxes usually have specifications of 10μl-150μl. Each box includes 20-400 capillary pipettes / tubes, and a single pipette and dripper attached to each tube. The capillary pipette is disposable, and the pipette and dripper are reusable. The existing clinical use of commercial whole box packaging of micro blood collection pipettes is to directly open the packaging box, or take out the micro blood collection pipette and put it in an open box, and then take it out for use when sampling. Because the micro blood collection pipette directly releases the patient's blood, the micro blood collection pipette stored in an open box may be contaminated during use, which poses a biosafety problem.

[0031] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0032] An automatic micro-blood collection pipette supply device, such as Figure 1-3As shown, it includes a cover 1, a shell 2 and a bottom plate 3, and the cover, shell and bottom plate are fixedly connected to each other. The shell is hollow inside, and the shape of the shell is not particularly limited, and can be cylindrical, box-shaped or other polygonal or irregular shapes with an inner cavity. Preferably, the shell is cylindrical.

[0033] like Figure 1-2As shown, the housing is provided with a straw storage device 4 which can rotate freely around the central axis of the housing, and a plurality of capillary straw insertion holes 5 are provided on the upper surface of the straw storage device. The straw storage device is used to store capillary straws, so the specific structure of the straw storage device is not particularly limited, and can be cylindrical, regular polygonal or other irregular bodies; in a specific embodiment of the present invention, the straw storage device is preferably a cylindrical body, and the cylindrical straw storage device keeps its center of gravity at the center to prevent the dispenser from being overturned by force during use. In a specific embodiment of the present invention, the number of capillary pipette holes provided on each straw storage device is 20-400, preferably the number of capillary pipette holes provided on each straw storage device is 20, 40, 60, 80, 100, 200, 400, and the capillary pipette holes are arranged in a circle at equal intervals on the upper surface of the straw storage device. Since the commercial micro-blood collection straws sold in boxes / packs are usually 20, the number of capillary pipette holes on each straw storage device is set to a multiple of 20, so that all capillary pipettes can be completely placed on one straw storage device. In a specific embodiment of the present invention, the size of the capillary pipette hole is greater than or equal to the size of the capillary pipette, and smaller than the size of the pipette connector. When in use, the head end of the capillary pipette can be inserted into the hole, and the pipette connector is exposed outside the hole. The doctor can directly put one end of the pipette on the pipette connector to take out the capillary pipette in the supply device, which is convenient and quick to use. In a specific embodiment of the present invention, there are 1, 2, 3, 4, or 5 straw storage devices, and preferably, there are 2 straw storage devices. When the number of straw storage devices is 1, the capillary straw plug hole is arranged at a position close to the shell, which is conducive to increasing the radius of the circumferential arrangement of the capillary straw plug holes, and more capillary straw plug holes can be arranged on a single straw storage device. When the number of straw storage devices is 2-5, different straw storage devices are cylinders with different axis overlap radii, and different specifications of capillary straw plug holes can be arranged on different straw storage devices. For example, when there are 2 straw storage devices, the diameter of the outer straw storage device is 10-30 cm, and the outer straw storage device is provided with 20 80 microliter capillary pipette plug holes, and the diameter of the inner straw storage device is 5-25 cm, and the inner straw storage device is provided with 20 40 microliter capillary pipette plug holes. The outer ring of the straw storage device stores 80 microliter capillary pipettes, and the inner ring of the straw storage device stores 40 microliter capillary pipettes. In this way, when in use, doctors can quickly identify the specifications and sizes of the corresponding micro blood sampling pipettes according to the inner and outer ring of the straw storage devices. In addition, the capillary pipettes of different specifications currently used in clinical practice mainly differ in length, that is, the capillary pipette holes of the inner and outer rings have the same diameter. According to the actual situation of the user, 20 microliter or 80 microliter capillary pipettes can be placed in the inner and outer ring of the straw storage devices, which can increase the storage capacity of the micro blood sampling pipette supplier of the present invention for capillary pipettes of a single specification.The attached drawings of the present invention exemplarily show the case where the number of straw storage devices is two. According to the principle of the present invention, a larger number of coaxially arranged straw storage devices may be provided. These solutions are all within the protection scope of the present invention. For example, in order to achieve more storage capacity and increase the volume of the shell, the number of straw storage devices is set to 3-10.

[0034] like Figure 3 As shown, in a specific embodiment of the present invention, a fixed shaft 6 is provided in the middle position of the automatic micro-blood sampling straw supplier, the fixed shaft is vertically arranged, the upper end of the fixed shaft is fixedly connected to the cover body, and the lower end of the fixed shaft is fixedly connected to the bottom plate. The straw storage device is fixedly connected to the ring sleeve 8 through a connecting member 7, and the connecting member can be a connecting rib or a connecting plate. The ring sleeve is sleeved on the annular groove on the surface of the fixed shaft, and the ring sleeve can rotate freely in the annular groove.

[0035] like Figure 3 As shown, in a specific embodiment of the present invention, a key and an elastic device for giving a rebound force to the key are provided on the cover body. The elastic device includes a spring barrel fixed to the lower surface of the cover body and a compression spring arranged in the spring barrel. The key passes through the cover body and the spring barrel. A fixedly connected block is provided on the surface corresponding to the key in the spring barrel. One end of the compression spring is fixedly connected to the block, and the other end is fixedly connected to the bottom surface of the spring barrel. The compression spring gives elastic support to the key, and after the key is pressed, the spring will give a rebound force.

[0036] In a specific embodiment of the present invention, in order to prevent the key from rotating during pressing, a vertical guide rail is provided on the side of the spring cylinder, and the card block is embedded in the vertical guide rail and can slide up and down along the guide rail.

[0037] like Figure 3 and Figure 4As shown, in a specific embodiment of the present invention, a pressing and rotating device is provided between the straw storage device and the key. The pressing and rotating device includes a convex tooth 13 arranged on the side of the straw storage device and fixedly connected thereto, and an upper shifting block 14 and a lower shifting block 15 arranged on the surface of the key near the convex tooth and fixedly connected to the key. The number of the convex teeth is twice the number of the capillary straw insertion hole, and each convex tooth is arranged circumferentially on the side of the straw storage device at equal intervals. An inclined surface 16 is provided at the lower end of the upper shifting block and the upper end of the lower shifting block. A shifting block groove 17 for the shifting block to be inserted is formed between two adjacent convex teeth. When the key is pressed down, the lower shifting block gradually moves downward to open the shifting block groove, and then the upper shifting block gradually moves downward to shift a convex tooth clockwise (or counterclockwise) through the inclined surface; when the key rebounds under the elastic force of the spring, the upper shifting block gradually moves upward to leave the shifting block groove, and the lower shifting block gradually moves upward to shift a convex tooth clockwise (or counterclockwise) through the inclined surface. Each time the button is pressed and released, the shift block shifts two convex teeth (the shifting distance is the distance between the two inclined surfaces of the shift block in the horizontal direction). Since the number of convex teeth is twice the number of capillary straw holes, the straw storage device rotates the arc of two adjacent capillary straw holes. For example, when the number of capillary straw holes is 20, the arc between two adjacent capillary straw holes is 18°. When the button is pressed and released, the shift block shifts two convex teeth, driving the straw storage device to rotate 18°. The rotation of the straw storage device will rotate the position of one capillary straw hole. In addition, when the upper shift block and the lower shift block are inserted into the slider groove, the shift block also serves to prevent the straw storage device from continuing to rotate, so that each time the rebound button is pressed, the straw storage device only rotates one capillary straw hole, so that the supply port can always only expose one capillary straw hole.

[0038] The number of buttons in the present invention corresponds to the number of straw storage devices, and one button is used to control the rotation of one straw storage device. For example, when there is one straw storage device, a button is provided on the cover body, and the button cooperates with the convex teeth on the inner surface or outer surface of the straw storage device through the shift block to control the rotation of the straw storage device. If there are two straw storage devices, one button cooperates with the convex teeth on the inner surface of the outer circle straw storage device, and the other button cooperates with the convex teeth on the outer surface of the inner circle straw storage device.

[0039] like Figure 1 As shown, in a specific embodiment of the present invention, the cover body 1 is provided with a supply port 18, which is in the shape of a fan-shaped port or a long strip-shaped port, and each straw storage device has a capillary straw insertion hole exposed at the supply port. The exposed capillary straw can be conveniently taken out through the supply port.

[0040] like Figure 1As shown, in a specific embodiment of the present invention, a dripper placement groove 19 is provided on the upper surface of the cover body 1. The dripper placement groove is a rectangular or square groove, and the placement groove can be used to place the pipe and the dripper.

[0041] In a specific embodiment of the present invention, an anti-slip device is provided on the lower surface of the base plate. The anti-slip device is a corrugated, silicone anti-slip pad or a suction cup. The anti-slip device can prevent the supply device from sliding during the operation of removing the capillary pipette, thereby increasing the safety of the operation.

[0042] In a specific embodiment of the present invention, a sliding cover 20 is provided on the supply port and the dripper placement groove, and the supply port can be closed by sliding the sliding cover. When not in use, the supply port can be closed by the sliding cover to prevent contamination.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the method of the present invention. These improvements and supplements should also be regarded as the scope of protection of the present invention.
