Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model, the technical scheme in the utility model is carried out clearly and completely Describe.

Refer to Fig. 1, the sterile test tube that the utility model can be introduced directly into mid-stream speciman of urine collection includes test tube the 1st, test tube The 3rd, lid the 2nd, self-closing seal fastens cylinder the 4th, capping plug 5, the upper end open of described test tube 1, and described test tube cap 2 is set in test tube 1 At upper end open, described test tube cap 2 includes that the block 21 being provided with insert port 22 is run through in centre, and block 21 is enclosed within test tube cap 2 upper end On opening, the lateral edges of block 21 and test tube cap 2 upper side clamping.The diameter of insert port 22 is less than test tube 1 internal diameter, along insertion The edge of mouth 22 vertically extends downwards and forms mouth of pipe wall 23, and mouth of pipe wall 23 bottom part ring is provided with a circle boss 24 around inwall.

Described self-closing seal 3 can be made up of soft material (such as silica gel), as it is shown on figure 3, which is and mouth of pipe wall 23 The circular cylindrical cavity of the upper end open with certain altitude of form fit, described self-closing seal 3 upper end open edge to Outer horizontal-extending formation one circle flange 31, the shape of flange 31 matches with the boss 24 on mouth of pipe wall 23.

The diapire of described self-closing seal 3 is provided with the otch 32 running through, and the shape of otch 32 can be multiple, such as cross Shape otch, the diapire of self-closing seal 3 is divided at least two valve 33 by otch 32, and described valve 33 is for being already cut into piece Shape or be cut into enclosed point type limb shape.In another embodiment, described self-closing seal 3 also can be a thin slice, The i.e. one circular plate-like shape structure mated with mouth of pipe wall 23 internal diameter, it is divided at least two valve 33 by otch 32.

When mounted, first self-closing seal 3 is stretched into from the insert port 22 of test tube cap 2, until on self-closing seal 3 The flange 31 in portion and the boss 24 of mouth of pipe wall 23 are against now self-closing seal 3 is affiliated on boss 24, then uses up and down The fastening cylinder 4 of opening stretches into from insert port 22, and the external diameter of fastening cylinder 4 is close with the internal diameter of insert port 22, and stretches into insert port 22 Rear bottom is in close contact with the flange 31 of self-closing seal 3, and the outer wall of fastening cylinder 4 is close to mouth of pipe wall 23, the top of fastening cylinder 4 Holding concordant with the top of test tube cap 2, the effect of described fastening cylinder 4 is to coordinate the flange 31 of self-closing seal 3 with boss 24 Clamping, such catheter 6 by when being inserted through the diapire of self-closing seal 3 under upper (as shown in Figure 4), self-closing seal 3 will not drop in test tube 1 because of the insertion of catheter 6.The block 21 of test tube cap 2 and test tube 1 upper end outer wall are used card The mode that tight or spiral connects fastens, and then uses capping plug 5 (as shown in Figure 2) to seal the upper end open fastening cylinder 4.Described Fastening cylinder 4 can be made up of the material (such as rubber) of flexible character.

When intercepting mud-stream urine, by the catheter 6 that connects with the urine cup of mid-stream urine collection from the insert port 22 of test tube cap 2 The upper end open of cylinder 4 (i.e. fasten) inserts, and by catheter 6, mud-stream urine is flowed into test tube 1 completely, the front end of catheter 6 from Otch 32 on self-closing seal 3 diapire passes, and at least two valve 33 split by otch 32 is at catheter Insertion action Lower to both sides separation, to reserve insertion space to catheter.

After test tube 1 intercepts mud-stream urine, self-closing after insert port 23 is extracted, bottom this insert port 23 for the catheter 6 The valve of seal 3 utilizes material natural elasticity can block bottom self, meanwhile, uses capping plug 5 to open the upper end fastening cylinder 4 Mouthful sealing, when mud-stream urine can be entirely sealed in mud-stream urine gathers in test tube 1, the mud-stream urine in urine cup can pass through urethral catheterization Pipe 6 flows directly in test tube 1, owing to mouth of pipe wall 23 and the self-closing seal 3 of test tube cap 2 stretch in test tube 1, so midstream urine Liquid will not take whole test tube 1, has stopped space so to the addition of follow-up reagent, it is not necessary to fall the mud-stream urine in test tube 1 Detecting after going out a part；In addition, after the mud-stream urine collection in test tube 1 completes, can directly catheter 6 be extracted i.e. Can.After catheter 6 is extracted, at least two valve 33 of self-closing seal 3 can automatically restore to original state, is i.e. formed by cutting The mud-stream urine of diapire lower end seals by the complete diapires of mouthfuls 32 segmentations, it is to avoid prior art needs to test tube cap or examination The outwarding winding back and forth or plug of pipe close, before considerably reducing inspection, the step after inspection, improves urine examination speed, reduces urine examination people The labour intensity of member；Coordinating the use of capping plug 5, this test tube can ensure to realize fully sealing after intercepting mud-stream urine, protects simultaneously Card germ-free condition, can directly go up machine testing or use urine sample test strips to detect to the urine sample in test tube after extracting capping plug 5.

The mouth of pipe wall 2 of test tube cap 2 has certain length simultaneously, has support fixation when inserting catheter 6, can prevent Only the catheter insertion rear left right side is rocked, and is more convenient for the collection of mud-stream urine.
