Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the field of pharmaceutical analysis instrument, concretely relates to a sampling auxiliary device for aerosol sample. BACKGROUND
[0002] For unpacked liquid preparations and liquid preparations packaged with aluminum caps, technicians can usually directly sample with a syringe for analysis and detection. However, for aerosols, the nozzle is extremely small and closed, so a syringe cannot be directly used for sampling.
[0003] Spray pumps used to package aerosols are usually divided into two types: screw pumps and roll pumps. Roll pumps are superior to screw pumps in terms of sealing, and are therefore widely used in the fields of cosmetics and pharmaceuticals. Currently, there are two common ways to sample roll pump aerosols: (1) repeatedly pressing the spray pump to spray the contents from the nozzle, and then collecting the mist droplets in a container; (2) using a clamp to remove or damage the spray pump head, and then using a syringe to extract. The first method is cumbersome and causes sample leakage, and the evaporation of the mist droplets increases the proportion of active substances, which increases the risk of detection accuracy. The second method has high safety risks, and the sampled sample cannot be resealed, which is not conducive to subsequent inspection operations. SUMMARY
[0004] The utility model aims at providing a sampling auxiliary device for aerosol samples, which can avoid spray evaporation or spray pump damage, and reduce potential safety hazards in the processing process.
[0005] To solve the above problems, the technical scheme of the utility model is as follows:
[0006] A sampling auxiliary device for aerosols, comprising a sleeve and a pressing block, the lower end of the sleeve is fixedly connected to a connector, the connector is connected to the top surface of the pressing block, a through hole is formed in the pressing block and is in communication with the connector, a sealing sleeve is arranged between the pressing block and the connector, the two ends of the sealing sleeve are in communication with the connector and the through hole respectively, and a plurality of clamping pieces are fixedly connected to the bottom surface of the pressing block.
[0007] The connector and the pressing block are threadedly connected, and a counterbore for accommodating the sealing sleeve is formed in the opposite end surfaces of the connector and the pressing block.
[0008] Wing blocks are extended from both sides of the pressing block.
[0009] An observation window is formed in one side or both sides of the sleeve.
[0010] A flange is arranged at the upper end of the sleeve, a groove is formed in the flange, and a clamping groove is formed in the inner wall surface of the groove.
[0011] The utility model has the advantages of:
[0012] 1. The utility model discloses a negative pressure principle is utilized, under the premise of not destroying the spray pump directly cooperate with the syringe and take out liquid preparation, simple operation, high efficiency, and will not cause sample leakage, guarantee the accuracy of the later test result.
[0013] 2. The spray sampling aid provided by the utility model can automatically close the nozzle after sampling is completed, keeps the remaining sample of the spray closed, and is very suitable for samples that need to be prevented from being misused. ACCURACY

[0020] In the drawing: pressing block 1, wing block 2, sleeve 3, flange 4, observation window 5, clamping piece 6, sealing sleeve 7, joint 8, syringe 9, sprayer 10, rolling port pump nozzle 11, clamping groove 41, recess 42, syringe nipple 91. DETAILED DESCRIPTION
[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.
[0022] As Figures 1 to 3 The utility model discloses a spray sampling aid, including sleeve 3 and pressing block 1, sleeve 3 lower end fixed connection joint 8, joint 8 with pressing block 1 top surface connection, be equipped with the through -hole of being linked with joint 8 in pressing block 1, be equipped with the sealing sleeve 7 made of silicon rubber between pressing block 1 and joint 8, and the both ends of sealing sleeve 7 are linked with joint 8 and the through -hole respectively, be equipped with multiple clamping pieces 6 on the bottom surface of pressing block 1, and multiple clamping pieces 6 are evenly distributed around the through -hole axis, and the positioning cage corresponding with sprayer 10 is enclosed by multiple clamping pieces 6.
[0023] When using this utility model: as follows Figure 4 and 5 As shown, the syringe 9 is placed into the sleeve 3, and the syringe tip 91 passes through the connector 8 and is inserted into the upper end of the sealing sleeve 7. At the same time, the connecting surface of the syringe barrel and the syringe tip 91 abuts against the connector 8. Then, the positioning cage is put over the sprayer 10 to position the sprayer 10 so that the nozzle 11 of the sprayer 10 is inserted into the lower end of the sealing sleeve 7. This allows the syringe tip 91 to align with the nozzle 11 of the sprayer 10, and the sealing sleeve 7 seals both the nozzle 11 and the syringe tip 91. The operator then places the sprayer 10 on the table, presses down on the lug of the syringe 9 with one hand, and pulls the piston of the syringe 9 with the other hand. The spray sample is drawn into the empty barrel of the syringe 9 through the spray pump nozzle. After the expected amount of sample is drawn, the syringe 9 is pulled out, and the sampling is complete.
[0024] like Figure 3 As shown, the connector 8 is threadedly connected to the pressing block 1. A countersunk hole for accommodating the sealing sleeve 7 is provided on the opposite end face of the connector 8 and the pressing block 1. The sealing sleeve is pressed between the connector 8 and the pressing block 1. In this way, the countersunk hole can be used to position the sealing sleeve 7, so that the syringe nipple 91 and the crimping pump nozzle 11 can be inserted into the set depth of the sealing sleeve 7, ensuring the sealing effect between the sealing sleeve 7 and the syringe nipple 91 and the crimping pump nozzle 11, and achieving effective docking.
[0025] A wing block 2 extends from each side of the pressing block 1. The wing block 2 allows the operator to easily hold the auxiliary device.
[0026] The upper end of the sleeve 3 is provided with a flange 4, on which a waist-shaped groove 42 is formed. A retaining groove 41 is formed on the inner wall of the groove 42. An observation window 5 is formed on one or both sides of the sleeve 3. The observation window 5 is used to observe the amount of sample taken. After the syringe 9 is placed into the sleeve 3, the syringe 9 can be rotated at an angle through the observation window 5, so that the syringe 9 lug rotates into the retaining groove 41. This allows the sleeve 3 to limit the syringe 9. During operation, the operator can press the bottom of the sprayer 10 with their thumb and place their index and middle fingers on the two wing blocks 2 to continuously press, so that the inside and outside of the collet pump are connected to the atmosphere. At the same time, the operator's other hand pulls the piston of the syringe 9 backward to draw the sample into the empty cylinder of the syringe 9. In this way, the sample can be drawn in the air, which further facilitates the operation.
[0027] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this utility model should not be considered as limited to the specific forms described in the embodiments. The scope of protection of this utility model also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
