Detailed Description

The present invention will be described with reference to the accompanying drawings, wherein the specific embodiments are described herein for illustrative and explanatory purposes only and are not limiting.

As shown in fig. 1 to 5, the clinical sterile test tube of the present embodiment includes a test tube body 1 and a tube cap 2 for sealing the tube opening of the test tube body 1. The tube cover 2 is provided with a jack 212, and the jack 212 is used for tightly inserting and fixing the non-wiping end of the cotton swab 3 and accommodating the cotton swab 3 in the tube body 1 when sealing the tube body 1. The sterile test tube for clinical use can contain a cotton swab 3, and the cotton swab 3 can be inserted into the insertion hole 212 all the time. Alternatively, sampling may be performed after a new swab 3 is inserted into the insertion hole 212 and fixed before use.

Further, the present embodiment also provides a new tube cap 2. Specifically, the tube cover 2 includes a lower cover body 21 and an upper cover body 22. The main body of the lower cover 21 is an inner sleeve 211 with one open end and one closed end, the outer side wall of the closed end of the inner sleeve 211 is provided with a convex clamping part 214, and the insertion hole 212 is arranged at the closed end of the inner sleeve 211. The main body of the upper cap body 22 is an outer sleeve 221 with an opening at one end and a sealed end, the inner wall of the outer sleeve 221 near the sealed end and the open end is respectively provided with an annular upper clamping groove 223 and an annular lower clamping groove 224, and the inner end surface of the sealed end of the outer sleeve 221 is further provided with a protruding hole blocking strip 222. The inner sleeve 211 can tightly sleeve the tube opening of the test tube body 1 in the inner sleeve 211, the outer sleeve 221 is coaxially sleeved outside the inner sleeve 211 and can slide along the inner sleeve 211, and the clamping portion 214 can be matched and clamped into the lower clamping groove 224 or the upper clamping groove 223 after the outer sleeve 221 slides, so that the hole blocking strip 222 can be inserted into or separated from the insertion hole 212.

The inner end surface of the closed end of the inner sleeve 211 is provided with a projecting close-fitting portion 213, and the close-fitting portion 213 is provided with a through hole coaxial with the insertion hole 212. The whole body is in a hollow round table shape. The cotton swab 3 is inserted into the through holes of the insertion hole 212 and the tight insertion portion 213 simultaneously when being fixed to the tube cap 2. At this time, the length of the hole blocking bar 222 is the sum of the length of the insertion hole 212 and the length of the through hole. The outer wall of the open end of the inner sleeve 211 is a chamfer 215, and the open end of the outer sleeve 221 is internally received by a tightening part 225 with a decreasing diameter.

The tube cap 2 of the present embodiment has two usage forms: the first case is a case where swab 3 is fixed to tube cap 2, and the second case is a case where swab 3 is ejected or used separately. In the first state, the distance between the sealing ends of the upper cover body 21 and the lower cover body 22 is the largest; at this time, the hole-blocking strip 222 is separated from the insertion hole 212, and the end of the swab 3 is tightly inserted into the through hole of the tight insertion portion 213 and the insertion hole 212. In the second state, the distance between the sealing ends of the upper cover 21 and the lower cover 22 is minimum, and the hole blocking strip 222 is inserted into the through hole of the insertion part 213 and the insertion hole 212 to completely block the insertion hole 212; if the jack 212 is plugged with finish 3, the swab can be pushed out for inspection or replacement.
