Description

Technical Field

[0001] This utility model relates to the field of sterile smear tools, and in particular to a sterile sampling smear tool for hospitals. Background Technology

[0002] Hospital-specific sterile smear tools are primarily used to collect and smear various microbial samples, such as bacteria, fungi, and viruses. These samples are then smeared onto culture media for culturing and observation of the microbial growth characteristics.

[0003] Traditional hospital-grade sterile application tools mostly adopt a one-piece structure and are discarded after single use. The use of disposable tools means that new materials need to be consumed each time they are used, which leads to a waste of resources. As the number of uses increases, the cost of disposable tools may become quite high, especially in the case of large-scale or frequent use.

[0004] Therefore, those skilled in the art have provided a hospital-specific sterile sampling smear tool to address the problems mentioned in the background section. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hospital-specific sterile sampling and smearing tool. By designing the traditional hospital-specific sterile smearing tool into two parts, a rod and a body, only the rod with the smearing head needs to be replaced after the test is completed. Compared with the traditional one-piece tool, which requires the entire tool to be discarded after use, this design reduces the cost of use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A hospital-specific sterile sampling and smearing tool includes a telescopic rod and a sterile rod. One end of the sterile rod is engaged with one end of the telescopic rod. One end of the sterile rod is integrally provided with a smearing head. Fixing holes are provided on both sides of one end of the sterile rod. A storage groove and a fixing groove are sequentially formed from the inside to the outside on both sides of one end of the telescopic rod. Limiting plates are slidably arranged inside the two fixing grooves. A pull rod is integrally provided in the middle of each limiting plate. A spring is sleeved on the outer end of the pull rod on one side of each limiting plate. A hemispherical ball is integrally provided on the end of each pull rod away from the spring.

[0008] With the above technical solution, by pulling the two rods outward to compress the spring, the hemisphere disengages from the fixing hole and enters the storage slot, thus allowing the sterile rod to be removed. When installing a new sterile rod, one end of the sterile rod is inserted into the telescopic rod, and the spring is compressed by squeezing the hemisphere. After the hemisphere enters the fixing hole, the spring returns to its original position, thereby fixing the sterile rod. This part of the design is simple and easy to operate.

[0009] Furthermore, a locking block is integrally provided on one side of one end of the sterile rod, and a locking groove is provided on the inner wall of one end of the telescopic rod;

[0010] The above technical solution integrates a locking block on one side of one end of the sterile rod and a locking groove on the inner wall of one end of the telescopic rod. The locking block and the locking groove limit the fixing hole and the hemisphere to be in the same direction.

[0011] Furthermore, a holding plate is integrally provided at one end of the telescopic rod, and multiple anti-slip strips are integrally provided on both sides of the holding plate;

[0012] The above technical solution integrates a gripping plate at one end of the telescopic rod to improve the versatility of tool gripping, and multiple anti-slip strips are integrated on both sides of the gripping plate to improve gripping stability.

[0013] Furthermore, both ends of the telescopic rod are provided with holding grooves;

[0014] The above technical solution provides gripping grooves at both ends of the telescopic rod, thereby improving the stability and comfort of the experimenter's grip.

[0015] Furthermore, the depth of each of the storage slots is greater than the length of the hemisphere;

[0016] With the above technical solution, the depth of each storage slot is greater than the length of the hemisphere, thus facilitating the storage of the hemisphere.

[0017] Furthermore, the diameter of the hemisphere is the same as the diameter of the fixing hole;

[0018] With the above technical solution, the diameter of the hemisphere is the same as the diameter of the fixing hole, thus facilitating snap-fit ​​fixing;

[0019] Furthermore, the insertion end of the telescopic rod is provided with multiple threaded holes, and an adjusting bolt is threadedly installed on one side of the sleeve end of the telescopic rod;

[0020] The above technical solution allows for easy adjustment of the overall length of the telescopic rod by adjusting the bolts and threaded connections to threaded holes at different positions.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model proposes a hospital-specific sterile sampling smear tool. By pulling two rods outward, the spring is compressed, and the hemisphere disengages from the fixing hole and enters the storage groove, thus allowing the sterile rod to be removed. When installing a new sterile rod, the fixing hole and the hemisphere are aligned in the same direction by the limiting blocks and slots. Then, one end of the sterile rod is inserted into the telescopic rod, and the spring is compressed by squeezing the hemisphere. After the hemisphere enters the fixing hole, the spring returns to its original position, thus fixing the sterile rod. This part of the design is simple and easy to operate. By designing the traditional hospital-specific sterile smear tool into two parts, the rod and the rod body, only the rod with the smear head needs to be replaced after the test. Compared with the traditional one-piece tool, which needs to be discarded after use, this design reduces the cost of use. The overall length of the telescopic rod can be easily adjusted by adjusting the bolt and threaded holes at different positions, making it convenient to collect samples from deep environments and inside instruments that are difficult to sample.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-5 This utility model provides an embodiment of a hospital-specific sterile sampling and smearing tool, comprising a telescopic rod 1 and a sterile rod 2. One end of the sterile rod 2 is engaged with one end of the telescopic rod 1. A smearing head 3 is integrally provided at one end of the sterile rod 2. Fixing holes 8 are provided on both sides of one end of the sterile rod 2. A storage groove 10 and a fixing groove 11 are sequentially formed from the inside to the outside on both sides of one end of the telescopic rod 1. Limiting plates 13 are slidably arranged inside both fixing grooves 11. A pull rod 12 is integrally provided in the middle of each limiting plate 13. A pull rod 12 is integrally provided on one side of each limiting plate 13. Springs 14 are fitted onto the outer ends of each pull rod 12. A hemispherical ball 15 is integrally formed at the end of each pull rod 12 away from the spring 14. By pulling the two pull rods 12 outward, the springs 14 are compressed, and the hemispherical ball 15 disengages from the fixing hole 8 and enters the storage groove 10, thereby allowing the sterile rod 2 to be removed. When installing a new sterile rod 2, one end of the sterile rod 2 is inserted into the telescopic rod 1. By squeezing the hemispherical ball 15, the springs 14 are compressed. After the hemispherical ball 15 enters the fixing hole 8, the springs 14 return to their original position, thereby fixing the sterile rod. This part has a simple design structure and is easy to operate.

[0032] A locking block 7 is integrally provided on one side of one end of the sterile rod 2, and a locking groove 9 is provided on the inner wall of one end of the telescopic rod 1. The locking block 7 and the locking groove 9 limit the movement so that the fixing hole 8 and the hemisphere 15 are in the same direction. A holding plate 5 is integrally provided on one end of the telescopic rod 1, and multiple anti-slip strips 6 are integrally provided on both sides of the holding plate 5. The holding plate 5 improves the versatility of tool holding, and the multiple anti-slip strips 6 on both sides of the holding plate 5 improve the stability of holding. Holding grooves 4 are provided at both ends of the middle section of the telescopic rod 1. Both ends of the telescopic rod 1 have holding grooves 4 to improve the stability and comfort of the experimenter's grip. The depth of each storage groove 10 is greater than the length of the hemisphere 15, making it convenient to store the hemisphere 15. The diameter of the hemisphere 15 is the same as the diameter of the fixing hole 8, making it convenient to achieve snap-fit ​​fixation. The insertion end of the telescopic rod has multiple threaded holes, and an adjusting bolt is threaded on one side of the sleeve end of the telescopic rod. The overall length of the telescopic rod can be easily adjusted by threading the adjusting bolt with the threaded holes at different positions.

[0033] Working principle: By pulling the two levers 12 outward, the spring 14 is compressed, and the hemisphere 15 disengages from the fixing hole 8 and enters the storage groove 10, thus allowing the sterile rod 2 to be removed. When installing a new sterile rod 2, the fixing hole 8 and the hemisphere 15 are aligned in the same direction by the limiting of the locking block 7 and the locking groove 9. Then, one end of the sterile rod 2 is inserted into the telescopic rod 1. By squeezing the hemisphere 15, the spring 14 is compressed. After the hemisphere 15 enters the fixing hole 8, the spring 14 returns to its original position, thus fixing the sterile rod. This part of the design is simple and easy to operate. By designing the traditional hospital-specific sterile smear tool into two parts, the rod and the body, only the rod with the smear head 3 needs to be replaced after the test is completed. Compared with the traditional one-piece tool, which requires the entire tool to be discarded after use, this design reduces the cost of use.
