Information query function
Including unit information query, reservation history query, physical examination status query, completion status query and physical examination report query. By selecting the query, you can know the inspection time of each person, whether there are any omissions in the entry of the inspection results on the day, whether the results are imported in time, the total inspection time, and the date of printing the report. You can also check the scheduled medical examination units, items and number of people.
Module 3—Drug Management Module
Drug storage function
When selling drugs, first determine whether the inventory balance is sufficient. If the balance is insufficient, purchases are required. When the purchase is completed, the drug storage operation is required to store the drugs in the inventory. And its accurate quantity is statistically saved (if there is a surplus in the inventory, the query operation can be performed, and the quantity can be added directly).
Drug delivery function
If the balance is sufficient, it needs to be sold, that is, the outbound operation, and the quantity change operation is performed according to different quantity requirements. The drug warehouse manager is responsible for the delivery of medicines. When the medicines are out of the warehouse, the warehouse administrators will release the medicines according to the actual varieties and quantities. For the varieties that are temporarily insufficient in stock, they must explain the situation and requisition as soon as possible. When the medicines are out of the warehouse, the medicine warehouse administrators must take a serious and responsible attitude, Check the quality and expiration date, verify the variety, specifications, etc., and strictly prevent the deteriorating and invalid drugs from leaving the warehouse. The prescription list is signed by the administrator of the drug storehouse and kept on file for future reference. There must be complete records for delivery orders, returned goods and delivery, inventory losses, loss reports, and drug sales.
Drug information management function
Drug information management includes detailed information of all drugs, such as place of origin, subject, category, specification, unit, selling price, approval number, production date, purchase price, expiration date, quantity and remarks. Drug information is the core hub of the drug invoicing management system, which determines the execution of other operations, such as query conditions, drug scrap conditions, and so on.
Module 4——Data Management Module
Patient Information Query
When patients see a doctor for the first time, they register a user with their work ID number or student ID number, and then register their own information. The patient information query module allows administrators, doctors or patients, and patient family members to query detailed patient information through their respective permissions. Such as contact information, home address, any family genetic diseases, etc. Information can be seen at a glance. It is convenient for doctors to conduct follow-up investigations, remind patients when to take medicine and what should be paid attention to in time.
The patient information query module includes recording the patient’s registration number, that is, the number registered at the clinic for the first time, and establishing a patient’s basic information database, such as name, age, gender, address, medical history, time of this visit, ID number and other information. Modules are managed by adding, deleting, and modifying information. Compared with previous handwritten records, computer records can manage patient information more conveniently and effectively.
Employee information query
Employee information management is to record employee-related information, including employee basic information, such as name, gender, age, etc., which can be easily managed by adding, deleting, and modifying relevant information, and classifying and statistically querying employee information. Managers can browse employee information, and when the personal situation of employees changes and needs to be modified, they can easily modify personal information.
According to different permissions, it is mainly for administrators and ordinary employees. Such a division can have different functions through different permissions, but they are closely related to each other, so dividing the system functions into multiple permissions is convenient for use and easy to understand and use.
