Description

Technical Field

[0001] The utility model belongs to the field of medical supplies, and in particular relates to a PCR eight-tube cover opener. Background Art

[0002] In the PCR molecular laboratory, 0.2ml PCR tubes are needed to hold nucleic acid solutions or reagents. When the number of samples exceeds 8, 0.2ml PCR eight-tube strips are needed. The PCR eight-tube strip is composed of 8 single PCR tubes with a volume of 0.2ml, and is a consumable for PCR experiments. Since the laboratory PCR instrument is generally arranged vertically with 8 PCR tubes, it is convenient for experimental operation, that is, PCR eight-tube strips, which are also suitable for PCR amplifiers. Since the size of the PCR eight-tube strip is very small, with a volume of only 0.2ml, the inspection technician usually needs to open the lid with his fingers and close the lid after the reagents or nucleic acids are added.

[0003] 1. Currently, most laboratories open PCR eight-tube strips by using the tip of the technician's thumb to pry them open. Due to the large number of eight-tube strips, the technician's thumb may feel pain or even be injured due to frequent opening of the tubes.

[0004] 2. Since the opening of the eight-piece tube cap mostly relies on the technicians' thumb tip, the operation is done one by one, which is very slow and inefficient.

[0005] 3. In addition, technicians usually wear medical gloves during the experiment. The fingers wearing medical gloves may have touched other objects. Opening the PCR eight-tube cap with fingers may cause contamination of the experimental results. Summary of the invention

[0006] The utility model aims to provide a PCR eight-tube cover opener which can prevent the inspection technician from being injured, has high cover opening efficiency and avoids experimental contamination.

[0007] The technical solution is as follows:

[0009] In one of the embodiments, a first opening point is disposed at the upper end of the cover-opening prying member, and a second opening point is disposed at the lower end of the cover-opening prying member.

[0010] In one embodiment, a clamping groove is formed at the lower end of the right side wall of the first cover opener, and installation grooves are formed on the upper and lower inner walls of the clamping groove.

[0011] In one of the embodiments, compression springs are fixedly installed inside the two installation grooves, and the ends of the two compression springs are fixedly connected with clamping blocks.

[0012] In one embodiment, a clamping column is fixedly connected to the left side of the second cover opener at a position corresponding to the clamping groove, and the clamping column has notches on the upper and lower sides thereof that are matched with the clamping block.

[0013] In one embodiment, the lid opening prying member is a pipette tip, and the insertion slot is in the shape of a cone that is wide at the top and narrow at the bottom.

[0014] In one of the embodiments, the shape of the cover-opening prying piece is adapted to the insertion slot, and the inside of the cover-opening prying piece is hollow.

[0015] In one embodiment, the height of the first cover opener and the second cover opener is half of the height of the cover prying member.

[0016] In one embodiment, the distance between two adjacent insertion slots is one centimeter to two centimeters.

[0017] In one embodiment, the elastic member is made of foam or rubber.

[0018] The technical solution provided by the utility model has the following advantages and effects:

[0019] 1. The utility model has a first opening point and a second opening point at the upper and lower ends of the opening pry piece. The first opening point can contact the eight-joint tube cover through the opening, and the eight-joint tube cover can be pried upward by tilting it upward at a certain angle. The second opening point is used for the eight-joint tube cover without protrusions, and is inserted into the gap for prying. It is no longer necessary for inspection technicians to use their thumbs to frequently open the cover, and their fingers will no longer feel pain.

[0020] 2. The utility model provides four insertion slots on each of the first cover opener and the second cover opener, with a total of eight insertion slots for inserting the cover opening prying piece, so that multiple covers can be opened at one time, which greatly improves the efficiency of cover opening and improves flexibility.

[0021] 3. By using this opener, it is more standardized than opening the cover with the fingers of technicians wearing medical gloves, and it is not easy to be contaminated.

[0022] 4. The utility model is provided with an insertion groove and an elastic member. By inserting the cover-opening pry piece into the insertion groove and clamping the cover-opening pry piece with the elastic member, the cover-opening pry piece is movably connected to the conical insertion groove. If individual cover-opening pry pieces are damaged, they can be easily replaced.

[0023] 5. The lid-opening prying piece is a pipette tip, which can conveniently adopt consumables commonly used in the art, with low cost and easy replacement. BRIEF DESCRIPTION OF THE DRAWINGS
