Description

Technical Field

[0001] The utility model belongs to the technical direction of retaining samples of medicinal liquids, and in particular relates to a sample retaining device which is easy to clean. Background Art

[0002] In the early stages of drug development, pharmaceutical research is still conducting comparative studies on different prescription dosage forms and is unable to provide complete stability test data for samples from different batches and production scales. Small-scale test samples should undergo influencing factor tests, accelerated tests, and long-term sample stability tests. The influencing factor test examines a batch of samples for 10 days. There are no rigid regulations on the batches and times of accelerated and long-term sample tests. The focus is on the results of accelerated tests and comparison with the results of long-term sample tests. The results of stability studies should ensure the stability of sample quality during the corresponding research and development period. With the progress of drug development, the demand for research samples continues to increase, the prescription process is basically determined, and the process is constantly being scaled up. Researchers need to conduct corresponding pharmaceutical research on samples of process scale-up, including stability studies.

[0003] The existing technology mostly uses a syringe to extract liquid medicine for sample retention operation. After extraction, liquid medicine will remain on the surface of the syringe. If it is not cleaned in time, it will drip onto the floor of the production workshop, affecting the production environment. In addition, the staff is required to wipe the surface of the syringe frequently, and the operation is cumbersome. When using the syringe to sample the liquid medicine, the staff needs to operate with both hands, which is inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0018] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The utility model provides a technical solution: a sample retention device that is easy to clean, including a sample retention device 1, which is placed in a production workshop and is used to absorb the produced liquid medicine for sampling operations. Two groups of placement holes are longitudinally installed on one side of the sample retention device 1, namely a first placement hole 11 and a second placement hole 12. Sample retention syringes 2 are detachably installed in the two groups of placement holes for absorbing the required liquid medicine for sample retention operations. A first scraper strip 111 is fixedly installed in the first placement hole 11, and a second scraper strip 121 is fixedly installed in the second placement hole 12. The two groups of scrapers are made of soft silicone material and are used to scrape off the residual liquid medicine on the surface of the sample retention syringe 2 during the disassembly process. At the same time, the sample retention syringe 2 will not be worn, so as to play a protective role. A first adjusting nut 13 is embedded on one side of the first placement hole 11, and a second adjusting nut 14 is embedded on one side of the second placement hole 12. The two groups of adjusting nuts are used to cooperate to control the tightness of the two groups of placement holes, thereby playing an effect of fixing the sample retention syringe 2;

[0020] A clamping seat 15 is fixedly installed on the other side of the sample retention device 1, and a clamping groove is penetrated on the clamping seat 15. Three groups of silicone pads are fixedly installed in the clamping groove, namely a first silicone pad 17, a second silicone pad 171, and a third silicone pad 172. The first silicone pad 17 and the second silicone pad 171 are located on both sides of the inside of the clamping groove, and the third silicone pad 172 is located at the inner top of the clamping groove. The clamping groove is used to cooperate with the sample retention device 1 to be clamped at the barrel mouth of the medicine liquid barrel. The first silicone pad 17 and the second silicone pad 171 can play an anti-slip and fixed role, and at the same time can reduce the wear of the medicine liquid barrel. The third silicone pad 172 can play an anti-slip role to prevent the sample retention device 1 from being displaced during the liquid collection process, causing the medicine liquid to spill out, and at the same time can reduce the wear of the sample retention device 1 on the barrel mouth of the medicine liquid barrel. A handle 16 is fixedly installed on one side of the clamping seat 15 for the convenience of the staff to grasp.

[0021] In this embodiment:

[0022] When the staff needs to use the sample retaining device 1 to perform the operation of sampling the liquid medicine, the staff first holds the sample retaining device 1 and the sample retaining syringe 2, and then puts the sample retaining syringe 2 into the two groups of placement holes. After the placement is completed, the staff manually screws the two groups of adjusting nuts respectively, so that the two groups of placement holes completely clamp the sample retaining syringe 2. At this time, the staff can use the sample retaining device 1 to perform the operation of sampling the liquid medicine. During the process of sampling the liquid medicine, the staff can grasp the handle 16 with one hand and pull the sample retaining syringe 2 with the other hand to perform the operation of sampling the liquid medicine, or clamp the clamping seat 15 on the sample retaining device 1 at the barrel mouth position of the liquid medicine barrel. At this time, the first silicone pad 17 and the second silicone pad 171 are attached to the barrel mouth wall of the liquid medicine barrel, which plays an anti-slip and anti-wear role. The third silicone pad 172 is attached to the mouth of the medicine barrel to play a role in fixing and preventing slipping. Then the staff can complete the medicine sampling operation by pulling the sample syringe 2 by hand. After the sampling is completed, the staff can lift the sample device 1 upward by holding the handle 16 to remove it. Then the staff manually adjusts the two sets of adjusting nuts to loosen the two sets of placement holes. Then the staff pulls the sample syringe 2 upward. During the upward movement of the sample syringe 2, the first scraping strip 111 can perform a preliminary scraping of the residual medicine on the surface of the sample syringe 2, and the second scraping strip 121 can perform a secondary scraping of the surface of the sample syringe 2 to prevent the residual medicine on the sample syringe 2 from dripping onto the floor of the production workshop, thereby reducing the subsequent cleaning cost.

[0023] By using two groups of placement holes in conjunction with the sample syringe 2, quick disassembly and assembly can be achieved. By using two groups of scraping strips in conjunction with each other, the residual liquid medicine on the surface of the sample syringe 2 can be scraped off during disassembly and assembly to prevent the liquid medicine from dripping onto the floor of the production workshop, thereby reducing the subsequent cleaning costs of the factory. By using the clamping seat 15 in conjunction with the handle 16, the liquid collection method can be changed according to different usage scenarios. The handle 16 can facilitate staff to hold the liquid medicine for sampling operations. The clamping seat 15 can be clamped at the mouth of the liquid medicine barrel for sampling operations. During the sampling process, the three groups of silicone pads can have an anti-slip and anti-wear effect, reduce the wear on the mouth of the liquid medicine barrel, and increase the service life of the liquid medicine barrel.
