Every inpatient and most outpatients need to undergo urine testing. It is the first choice for diagnosing diseases, observing therapeutic effects, and judging prognosis. Urine will be collected in a urinary catheter (cap with a punctureable membrane + sampling tube), labeled, and placed on a sample rack for subsequent sampling and testing by medical staff. After sampling, the remaining urine needs to be poured out and the urinary catheter needs to be recycled. At this time, because the hole for puncture sampling is very small, it is necessary to unscrew the caps on the urinary catheter one by one and then pour out the urine, which is time-consuming and laborious.

[0033] The utility model is specifically introduced below in conjunction with the accompanying drawings and embodiments. Example 1

[0034] This embodiment provides a puncture device, such as Figure 1 As shown, the puncture device is an integrally formed structure, having a grip portion 2, the bottom of the grip portion 2 is a horizontal plane, ten puncture portions 3 are spaced apart at the bottom of the grip portion 2, the puncture end of the puncture portion 3 is a multi-blade conical structure, and a plurality of reinforcing ribs 4 are formed at the connection between the puncture portion 3 and the bottom of the grip portion 2.

[0035] In actual application, the operator holds the puncture device 1 through the gripping part 2, and then aligns the puncture part 3 with the urinary catheter on the sample rack and presses down to puncture the puncture membrane of the urinary catheter cover in batches, and then tilts the sample rack as a whole to dump the residual urine in the urinary catheter, and then removes the urinary catheter for recycling, avoiding the tediousness of unscrewing the cover. The puncture end with a multi-blade tapered structure can improve the puncture effect, and the presence of the reinforcing rib 4 improves the stability of the overall structure. Example 2

[0036] When puncturing the urine catheters on the sample rack in batches, the operator is required to hold one end of the sample rack with one hand and hold the puncture device with the other hand to perform the puncture operation. However, in actual operation, it is found that when applying force for puncture, the end of the sample rack that is not held will often shift due to force problems. In severe cases, the sample rack will tilt and cause urine to spill onto the operating table.

[0037] Therefore, this embodiment provides a puncture mechanism that can process urine catheters in batches to solve the problem of sample rack movement during the puncture operation. Figure 2 As shown, the puncture mechanism includes the puncture device 1 provided in Example 1 ( Figure 1 ) and a sample holder 5 for placing a urinary catheter ( Figure 3 ), further comprising a weight base 6 and a support plate 7, wherein an upward protrusion is formed at the center of the weight base 6, and a groove corresponding to the protrusion is formed at the center of the bottom of the support plate 7, and the support plate 7 is placed on the weight base 6 and the protrusion of the weight base 6 is inserted into the groove of the support plate 7, so that the support plate 7 can rotate relative to the weight base 6. In actual application, the overall size of the support plate 7 is larger than that of the weight base 6, and a notch 8 extending backward is formed at the front end of the support plate 7, which is convenient for the subsequent pouring of urine.

[0038] A support member for fixing the sample rack 5 is slidably arranged on the support plate 7. At the same time, support columns 9 for installing the puncture device 1 are symmetrically arranged on the support plate 7 located on both sides of the support member. A first countersunk hole 10 is opened at the top of each support column 9, and a first slideway 11 connected to the corresponding first countersunk hole 10 is vertically opened on the side where the support columns 9 are close to each other, and a first support spring 12 is arranged in the first countersunk hole 10; first connecting members 13 are symmetrically arranged on both sides of the gripping part of the puncture device 1, the first connecting member 13 passes through the first slideway 11 and the end thereof is embedded in the first countersunk hole 10 and abuts against the top of the first support spring 12, and a sealing plug 14 is also screwed in the first countersunk hole 10 located above the first connecting member 13; the puncture device 1 is located above the sample rack 5, and the puncture part of the puncture device 1 is arranged one-to-one with the urinary catheter on the sample rack 5.

[0039] The support member includes a concave frame 15, and the bottom of the concave frame 15 has two sliders 16. A slide groove 17 corresponding to the slider 16 is provided on the support plate 7, and the slider 16 is embedded in the slide groove 17. The slide groove 17 and the slider 16 are both convex. A second countersunk hole 18 is provided on the top of the two side plates of the concave frame 15, and a second slideway 19 connected to the corresponding second countersunk hole 18 is vertically provided on the side where the two side plates are close to each other, and a second support spring 20 is provided in the second countersunk hole 18; a second connecting member 21 is installed on both sides of the sample rack 5, and the second connecting member 21 passes through the second slideway 19 and the end thereof is embedded in the second countersunk hole 18 and abuts against the top of the second support spring 20. In order to facilitate the subsequent pushing of the concave frame 15, a push-pull rod 22 can also be provided at the front end of the two side walls of the concave frame 15.

[0040] Furthermore, the first connecting member 13 and the second connecting member 21 both include a slide bar 23 and a pressing plate 24; wherein one end of the slide bar 23 of the first connecting member 13 is detachably connected (threaded) to the side wall of the gripping portion of the puncture device 1, and the other end is detachably connected (threaded) to the side wall of the pressing plate 24 of the first connecting member 13; the pressing plate 24 of the first connecting member 13 is embedded in the first countersunk hole 10 on the support column 9 and is slidably connected to the first countersunk hole 10; one end of the slide bar 23 of the second connecting member 21 is detachably connected (threaded) to the side wall of the sample holder 5, and the other end is rotatably connected to the side wall of the pressing plate 24 of the second connecting member 21; the pressing plate 24 of the second connecting member 21 is embedded in the second countersunk hole 18 on the side plate of the concave frame 15 and is slidably connected to the second countersunk hole 18. The above structure makes the puncture device 1 unable to rotate, while the sample holder 5 can rotate, so as to facilitate the dumping of urine at a later stage. The above-mentioned threaded connection can be achieved by opening threaded holes on corresponding connecting parts and machining corresponding threads on the ends of the slide rods 23, which will not be described in detail here.

[0041] The structure of the sample holder 5 is as follows Figure 3As shown, it is specifically a square frame, a through hole 25 for inserting a urinary catheter is opened on the top plate of the square frame, and an upward supporting seat 26 with a center hole is formed on the bottom plate of the square frame. In actual application, in order to prevent the urinary catheter from slipping off the sample rack 5 when urine is poured, a rubber ring can be set in the through hole 25 and the center hole of the supporting seat 26 to improve the stability of the urinary catheter.

[0042] In actual application, the puncture mechanism can be directly placed beside the urine recovery pool on the operating table, and the weighing base can correspond to the edge of the recovery pool. After sampling, the urine in the urinary tube placed on the sample rack 5 can be directly pushed by the concave frame 15 to drive the sample rack 5 to the bottom of the puncture device 1, and then the puncture device 1 is slowly pressed down to act on the urinary tube on the sample rack 5. After the bottom end of the sample rack 5 contacts the bottom surface of the concave frame 15, force is continued to be applied so that the puncture part of the puncture device 1 can puncture the puncture membrane on the cover, thereby effectively avoiding the displacement of the sample rack 5 during the puncture operation and the possible spillage of urine.

[0043] After the puncture membrane on the urinary catheter is punctured, slowly release the puncturator 1 to gradually reset the second support spring 20 and restore the sample table to its initial position, then rotate the support plate 7, turn the side of the support plate 7 with the notch 8 toward the urine recovery tank, and then pull the sample rack 5 to the edge of the notch 8 through the push-pull rod 22, and then rotate the sample rack 5 to tilt the urinary catheter, and then pour the urine in the urinary catheter into the urine recovery tank. After the pouring is completed, the urinary catheter can be removed from the sample rack 5.

[0044] The above is only a preferred implementation of the utility model patent. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model patent. These improvements and modifications should also be regarded as the protection scope of the utility model patent.
