Description

Technical Field

[0001] The utility model relates to the technical field of medical protection, in particular to an isolation sampling device. Background Art

[0002] The culture of the pharyngeal isthmus of a normal person should show normal oral flora, but no pathogenic bacteria. The bacteria in the pharynx come from the outside world and are not pathogenic under normal circumstances. However, they can cause infection and lead to diseases when the body's systemic or local resistance is reduced or other external factors occur. When diagnosing and treating infectious diseases such as hepatitis and tuberculosis, bacterial culture of pharyngeal swabs can isolate pathogenic bacteria, which is helpful for treatment.

[0003] Currently, when taking throat swab samples, you need to wear disposable gloves to protect your hands, a medical mask to protect your mouth and nose, and eye protection to protect your eyes. However, this will inevitably lead to close contact with the patient and there is still a certain degree of infection risk.

[0004] The patent with announcement number CN212698949U discloses a splash-proof throat swab sampling auxiliary device, including a seat, a baffle body, a first support rod and a second support rod; a first support rod is vertically arranged on the upper end surface of the base, and the first support rod is a telescopic rod; a second support rod is vertically arranged on the top of the first support rod. The baffle body can effectively prevent the droplets sprayed by the patient during throat swab sampling from splashing onto the mask and protective clothing of the collector, and the protective effect is good. Fixed clips are respectively arranged around the back of the baffle body, which is convenient for installing and replacing the isolation film on the front of the baffle body, so that the sampling auxiliary device can be reused and has strong practicality.

[0005] The above device requires the protective plate to be completely covered when using a replacement film, and each time a replacement is made, medical staff are required to move to the exposed side of the protective plate to clamp and replace the four corners. This not only increases the cost of the film during replacement, but also increases the walking workload of medical staff and the risk of infection, and is not very practical. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0027] As an optional implementation, the protection plate 1 is arc-shaped and transparent, which is convenient for observation.

[0028] Specifically, the opening slit 12 is designed to be easy to tear with rows of holes, so that the plastic film 11 can be in a closed state when the opening slit 12 is not opened. At the same time, the size of the opening slit 12 can be set according to actual conditions.

[0029] Furthermore, the elastic structure includes two elastic bands 13, and the two elastic bands 13 are fixedly connected to the surface of the protective plate 1, and the plastic film 11 passes through the two elastic bands 13 in turn. The elastic force of the two elastic bands 13 can fix the plastic film 11 at the sampling port 4 and fit tightly to the surface of the protective plate 1.

[0030] Reference Figure 4 As shown, two rubber strips 8 are fixedly connected in the installation seam 7. The two rubber strips 8 are staggered and the upper ends of the two rubber strips 8 are inclined. After the plastic film 11 is inserted into the installation seam 7, the two rubber strips 8 can be in contact with the plastic film 11. At the same time, the staggered rubber strips 8 can improve the fixing effect of the plastic film 11.

[0032] Specifically, a handwheel is provided below the second ear plate 3a to drive the upper transmission wheel 3b to rotate. The transmission wheel 3b and the transmission belt 3c are both synchronous wheel / belt designs. The handwheel can facilitate the rotation of the transmission wheel 3b. At the same time, the synchronous wheel / belt design can prevent slipping during rotation.

[0033] With the above structure, when in use, the rolled plastic film 11 is sleeved on the mounting rod 10, and the end of the plastic film 11 is pulled to pass through the mounting slit 7 on the fixed shaft 6.

At this time, the plastic film 11 is wound on the fixed shaft 6, and the opening slit 12 moves to the sampling port 4, and sampling is carried out by breaking the opening slit 12. After the sampling is completed, the plastic film 11 is driven to be rolled up by the transmission structure 3, the plastic film 11 in the exposed area is rolled up, and a new plastic film 11 is formed at the sampling port 4 to continue sampling.

[0034] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
