Technical Field

[0001] The utility model relates to a medical device, in particular to a device for measuring the viscosity of a drug when the drug is prepared for patients with dysphagia. Background Art

[0002] Swallowing disorder is a clinical manifestation that food cannot be safely and effectively delivered from the mouth to the stomach due to damage to the structure and / or function of organs such as the mandible, lips, tongue, soft palate, throat, and esophagus. In the clinical process, there are some common phenomena. Patients need to take oral medications before and after meals. For patients with swallowing disorder, tablets and water are solid and liquid respectively. Patients have great difficulty in swallowing drugs. Clinically, patients are advised to crush the tablets and dissolve them in water, add thickeners, and mix them to a consistency suitable for patients for swallowing. At present, the judgment of the consistency of drug preparation in clinical practice relies on the estimation of the dripping speed of the spoon; according to the IDDSI framework, the syringe dripping method is used. The specific operation process is: usually hold the syringe with one hand and block the syringe nipple with a finger, and fill it with the other hand. After filling, the liquid drips to evaluate the consistency; because the syringe has no effective fixation and storage, there are defects such as cumbersome operation and inconvenient storage in the later stage.

The device includes a shelf 1, an empty syringe barrel 2 for dripping, a filling syringe 3 and a timer 4. The shelf 1 includes an upper shelf plate 11, a base 12 and a plurality of supporting longitudinal beams 13. The upper shelf plate 11 is mounted on the base 12 via the supporting longitudinal beams 13, and an overhead space is formed between the upper shelf plate 11 and the base 12. The upper shelf plate 11 is provided with a fixing hole and a placement hole leading to the overhead space. The empty syringe barrel 2 for dripping is inserted into the fixing hole, and the filling syringe 3 can be inserted into the placement hole in a removable manner. The timer 4 is fixed on the upper shelf plate 11. The nipple 21 of the empty syringe barrel 2 for dripping is provided with a plugging piece 5 for opening and closing the mouth of the nipple 21. The shelf 1 is also provided with a protective barrel 6 that can cover the shelf 1. Figure 2 As shown, the shelf 1 is covered with a protective barrel 6 for storage.
