Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

The present invention provides a vaccine management system, as shown in fig. 1, comprising:

a vaccine storage device for storing a vaccine,

one or more vaccine distributing devices for distributing vaccines, wherein the vaccine distributing devices comprise a storing device for storing the vaccines, a recording device for storing the distributing quantity, the distributing time and the residual vaccine quantity, and a wireless communication device for communication;

a processing unit to:

obtaining the amount of vaccine consumed from the one or more remote vaccine dispensing devices; the processing unit is in wireless communication with the vaccine distribution device and reads the vaccine distribution quantity stored by the recording equipment on the vaccine distribution device as the consumed vaccine quantity;

obtaining from the vaccine storage device a quantity of vaccine stored in the vaccine storage device; for example, the vaccine storage device is provided with a counting device for detecting the number of vaccines in the vaccine storage device, such as detecting and storing the number of vaccines in the vaccine storage device by weight detection, contact detection, optical detection and other methods, and the processing unit performs wired or wireless communication with the vaccine storage device to read the number of vaccines stored in the vaccine storage device;

The processing unit is communicated with the vaccine storage device and the vaccine distribution device to obtain the use data of the vaccine storage device and the vaccine distribution device, so that the number of the ordered vaccines can be obtained through statistics to ensure that the probability of the vaccine stock shortage is lower than a preset value.

In order to accurately determine the number of ordered vaccines required for the probability of vaccine out-of-stock below a preset value, in an embodiment of the present invention, the obtaining the number of ordered vaccines according to the obtained data includes:

S＝(Q+R)×M^-1×(a+Z_α/2×b^0.5)-T

wherein S is the number of vaccines to be ordered, Q is the number of days between which the vaccine is ordered, R is the number of days in which the vaccine is in stock after ordering the vaccine, M is the period of the statistical number of vaccine consumptions, a is the average value of the vaccine consumptions in the number of days M of the cycle, b is the variance of the vaccine consumptions in the number of days M of the cycle, and T is the vaccineInventory of vaccine at order time, Z_α/2P ═ Φ (Z) corresponding to probability of occurrence of outage_α/2) Z of (A)_α/2The value is obtained. In one embodiment of the present invention, as shown in fig. 2, which is a schematic diagram of the variation of time-stock of vaccines in the embodiment of the present invention, in a certain vaccination clinic, the amount of a certain vaccine consumed every M days is X, then X-N (a, b), where X-N (a, b) represents that a random variable X obeys a normal distribution or an approximately normal distribution, where a is the average of the normal distribution and b is the variance of the normal distribution, if the vaccination clinic needs to order a vaccine every Q days, the actual stock of a certain vaccine at the ordering time point is T, and the vaccine can be delivered after the ordering time point is R days, because the use of the vaccine appears: the periodic variation of "-consumption-order-replenishment-" so that the stock quantity (solid line) of the vaccine varies in a broken line pattern in a coordinate system with time as the abscissa and stock quantity as the ordinate. And | df | represents the number of vaccines to be ordered in any period, and the geometric relationship of the line segment shows that:

|df|＝|dn|-|fn|＝|dn|-(|gc|-|ef|)＝|dn|+|ef|-|gc|

if the number of vaccines to be ordered at a time is defined as S, the above equation can be expressed as equation (1):

s is the stock of a certain vaccine ordered to the goods at this time + the consumption of a certain vaccine within R days-T

The left side of formula (1) is the quantity to be solved, the right side of formula (1) is the calculation method, wherein the term T is an item which can be used for determining the number of each vaccination clinic. The storage quantity of a certain vaccine after the order is finished at this time and the consumption quantity of the certain vaccine within R days can be converted into: and performing interval estimation calculation on the data by adopting a probability density curve mode on the basis of historical data. In view of the operational manner in which "stock" is not available, but can be allowed to exist, during vaccine use, a more "conservative" upper limit estimate is used for the potential vaccine consumption during the calculation of the data interval.

According to the calculation requirement, the data interval estimation of the 'stock quantity of the certain vaccine ordered to the goods at this time' can be actually defined as 'the available consumption (stock) quantity of the certain vaccine with the probability of the occurrence of the goods failure phenomenon lower than P in Q days'. The data interval estimate for "consumption of a certain vaccine within R days" may also be defined as "upper limit of consumption of a certain vaccine within R days (1-P1)". P and P1 are variables that need to be set manually, and range from 0% to 100% (generally, the medical reference value range can be set to 5%, or more "conservative" can be set to 99% or higher), and P is defined as P1 for ease of calculation.

From the above analysis, Q and R are known amounts for a general vaccination clinic, and both values are generally considered to be fixed constants, and can be easily obtained even for variable values, and thus, detailed description thereof is not necessary.

Because computer information management is almost realized in the vaccination outpatient service in China, calling historical vaccination data and making simple data analysis become simpler things, and M, X, a and b variables can be realized by the method, for example, calling 2016 previous certain vaccination data, setting M to 7, namely, the vaccination condition of a certain vaccine every 7 days, and obtaining the values of X, a and b by using the simple data analysis function of EXCEL software, so that X-N (a and b) can be easily proved as long as the value of M is not too small (higher than the vaccination date arrangement interval of a certain vaccine). Thus equation (1) can be converted to:

S＝Q×M-1×(a+Z_α/2×b0.5)+R×M-1×(a+Z_α/2×b0.5)-T

simplifying to obtain:

S＝(Q+R)×M-1×(a+Z_α/2×b0.5)-T

wherein P ═ Φ (Z)_α/2) That is, Z is determined by a probability density (normal distribution) curve method for a given P value_α/2The value of (a).

In order to take into account that some vaccines will be carried out and may be incomplete, there is a chance of returning the vaccine, in which case, in order to more accurately determine the vaccine to be ordered,

the processing unit is further configured to:
