Description

  The present invention relates to a device for determining an appropriate amount of a suppository divided position or dividing the suppository into an appropriate amount when the suppository is administered in an appropriate amount.

  A suppository is a drug inserted through the anus, which is useful for administering antipyretic, analgesic, nausea, anticonvulsant drugs or antibiotics to patients who are difficult to take in children, etc. Indispensable to. The dose of suppositories is regulated by the patient's body weight. In children with a body weight of 10 kg or less, the use of one suppository may result in overdose, and it is often necessary to divide with a cutter or scissors.

  Drug manufacturers are not recommending split use because of the possibility of uneven distribution of ingredients even in the same suppository, and the indication of dose split on the suppository case surface (Marks indicating 1/2, 1/3, etc. of the total amount) are not attached. However, past studies have confirmed that there is no non-uniformity that causes problems, and it is possible to divide an appropriate amount so as to achieve the desired drug efficacy and prevent overdose. By the way, the result of the inventor's investigation on the result of dividing the suppository by the hand of an expert pharmacist with the goal of being ¼, 1/2, 3/4, etc. of the whole suppository by weight ratio is the actual division There was a considerable difference between the weight and the target split weight, and the need for appropriate tools was recognized for the proper split. In other words, a scale that determines the division location or a cutter that divides into an appropriate amount is required.

  So far, no publicly known literature on the technology for dividing suppositories into appropriate amounts can be found, but the technology on the scale for dividing foods that are solids, especially cakes, like suppositories, is disclosed in Patent Literature 1 and Patent Literature 2. Has been. Patent Document 1 discloses a technique of attaching division marks along the outer periphery of the cake on the surface on which the cake to be wrapped is placed in the paper or plastic film for packaging the cake. Patent Document 2 discloses a technique for adding division marks to a tray for storing food. The division scales in these documents assume that the object to be divided is a simple cylinder or prism. For example, when dividing a cylindrical object in the longitudinal direction, the angle between the center line of the bottom surface and the division part The linear scale is based on the assumption that the proportion is proportional, or if the column is generally columnar, the distance from one end and the proportion of the divided portion are proportional.

However, the suppository has a shape in which one end is pointed for the purpose of facilitating insertion from the anus, and the other is formed by cutting one end of a bullet-shaped or spindle-shaped solid cut by a substantially flat surface. An example of the shape is shown in FIG. 3, and a shape similar to FIG. 3 is hereinafter referred to as a spindle shape, a sharp end portion is referred to as an insertion portion, and the other cut shape is referred to as a tail portion. When dividing a suppository having such a shape into a predetermined amount, the distance corresponding to the predetermined amount is measured from the insertion portion as a starting point and cut. However, the amount shown in FIG. It is difficult to determine the division position because there is no proportional relationship because it is not a columnar shape. Even if the suppository insertion part is used as a starting point and measured with a ruler, for example, even if the suppository is divided at a position such as 1/2 or 1/3 of the total length of the suppository, the amount of the drug itself is not proportional to the amount of division by the measured distance. In some cases, a large difference may occur between the target divided amount, which may hinder proper dosage. There has been a demand for a scale that can easily determine an appropriate amount or a tool that can be divided into appropriate amounts, but no specific technique has been proposed so far.

  The problem to be solved is to provide an easy-to-use, simple and low-cost suppository splitting device that does not cause an excessive difference with respect to the target split amount when splitting the suppository into target amounts.

  A pedestal that constitutes the suppository split position measuring scale, and a concave portion having substantially the same shape as a half of the suppository in the longitudinal direction, part of the suppository in the longitudinal direction, for example, a plane including the longitudinal center line of the suppository A distance corresponding to the target suppository split amount, based on the position of the apex corresponding to the suppository insertion portion of the opening opened on the pedestal surface of the recess, on the base surface around the opening of the recess We devised a suppository splitting device composed of scales graduated at a certain position. The scale is applied based on the result of measuring in advance the correspondence between the dose to be divided according to the shape of the suppository and the distance from the cusp. In addition, it is possible to adjust the position of the cutter having a blade in a direction substantially perpendicular to the longitudinal center line of the concave portion on the surface of the pedestal along the suppository-shaped concave portion in the direction of the central line. A device that attaches and cuts the suppository at a position that matches the scale can also be constructed.

  The invention described in claim 1 is a recess on the surface of the pedestal, and has an opening shape substantially the same as the cross section of the suppository cut along a plane parallel to the longitudinal center line of the suppository, and the shape of the recess is the plane. In the three-dimensional shape of the suppository divided into two, and having the same shape as the smaller one, and one of the longitudinal directions of the opening along the longitudinal direction of the opening of the concave portion on the surface of the pedestal Starting from this end, a scale is attached to the position corresponding to the target dose for dividing the suppository. In the above configuration, the suppository is fitted to the concave portion so as to conform to the shape of the concave portion, and used as a division scale for measuring the position to be divided by referring to the scale. In addition, the surface of the pedestal needs to ensure flatness so that the correspondence between the suppository fitted in the recess and the scale is within the required accuracy as the distance from one end in the longitudinal direction of the recess opening. The shape to be included needs to be approximately the same as the cut portion shape of the suppository to be divided to such an extent that the correspondence between the divided drug amount and the distance from the opening peak falls within an allowable error.

  In the device of claim 1, the plane parallel to the suppository center line does not necessarily pass through the longitudinal center line of the suppository, and the distance from the center line of the suppository from the apex of the recess opening. The correspondence between the distance and the division amount may be changed. When used for the purpose of determining the division position of a suppository that does not completely fit in the recess, multiple scales corresponding to the size of the suppository can be attached.

  The invention according to claim 2 is a case where the shape of the concave portion provided on the surface of the pedestal is substantially matched with a three-dimensional shape divided into two by a plane passing through the longitudinal center of the suppository. By uniquely determining the cutting plane of the suppository, there is an effect that it is possible to prevent an error in determining the division position.

  The invention according to claim 3 is that the suppository has the substantially spindle shape shown in FIG. 3 as described above (however, the tail portion has a shape obtained by cutting the tip), and the suppository division position should be measured from the insertion portion side. In consideration, one end of the opening of the recess provided in the pedestal corresponds to a spindle-shaped tip apex corresponding to the spindle-shaped sharp end, and the other end of the opening cut the spindle-shaped end It is a shape. Naturally, the depth shape of the recess must substantially match the three-dimensional shape cut by the above-mentioned plane of the spindle shape corresponding to the cross section. By making the recess into such a shape, the suppository, which is usually spindle-shaped, can be set without error in the opening of the pedestal, and there is an effect of preventing erroneous division.

  The invention described in claim 4 is obtained by adding a split blade to the suppository split scale described in claims 1 to 3 as shown in FIG. The blade is a blade that moves the suppository contained in the recess in a direction that cuts the suppository in a direction substantially perpendicular to the longitudinal center line of the suppository, and slides substantially parallel to the center line (that is, substantially parallel to the suppository center line). It is attached to the base.

  In order to determine and divide a plurality of different shapes or sizes of suppositories as shown in FIG. 6, a device according to claim 5 is provided with a plurality of recesses and scales on one pedestal and as required. With a knife. Providing in advance a recess or the like corresponding to the type of suppository normally used by a pharmacy helps improve work efficiency.

  The inventor conducted an investigation to confirm the accuracy of the suppository division, and confirmed the effect when the tool related to the present invention was not used and when it was used. For 20 pharmacists, the error with respect to the target divided dose when the division position is determined without using the tool of the present invention and the similar error when the tool of the present invention is used are the target divided dose 1/4, 1 FIG. 4 shows the result of totalization for / 2, 3/4. The horizontal axis in FIG. 4 represents the target division amount, and the vertical axis represents the actual difference in the division amount with respect to the target amount as a percentage (expressed as a percentage). Plus indicates that the actual amount is larger than the target, and minus indicates the smaller case. . As is apparent from FIG. 4, when the tool of the present invention is not used, the division target of 1/4 is an error of 35% when the tool of the present invention is not used, 1/2 is −15%, and 3/4 is There is an error of minus 5 to plus 10%, but when using the device of the present invention, the error is greatly reduced to minus 15%, ± 3%, and ± 1%, respectively. . Even if it is not a pharmacist having skills and knowledge, it is possible to easily cut out an appropriate amount at home and the like, which has a great effect on improving medical safety and reducing medical work.

  FIG. 1 shows a division position measuring scale which is the best mode for carrying out the suppository dividing tool of the present invention. The division position measurement scale 1 includes a pedestal 2, a concave portion 3 provided on the surface thereof, and a scale 4 indicating the division position. For the pedestal 2, a polymer resin is optimal in view of the ease of forming the recess, but any material can be used as long as it can hold the shape of wood, metal, etc., and can process the recess and scale. The concave portion 2 is formed by cutting the pedestal into a shape in which the suppository to be divided is divided in half along the longitudinal center line, or by another appropriate method. The scale is made by a method such as engraving or digging into the pedestal so as to indicate the position where the suppository 5 is divided into an appropriate amount. As a scale, it is preferable to divide into 1/4, 1/2, and 3/4 with respect to the whole amount of suppository. In order to determine the position of the scale 4, the suppository is cut little by little from the tail portion to obtain a desired division amount, and the distance from the insertion portion to the cut position in that state is determined as the insertion portion equivalent position 7 of the opening 6 of the recess 2. Measure and sculpt on the base surface. FIG. 2 is a photograph of an example of the suppository split position scale shown in FIG.

  FIG. 5 shows an embodiment of a suppository dividing tool in the device described in claim 4. The pedestal 2 and the recess 3 are formed in the same manner as in FIG. 1, but in addition, a rod-like member 10 whose both ends shown in FIG. 5 are supported by the support member 8 is attached substantially parallel to the center line of the recess 3. The rod-like member 10 passes through a hole formed in the attachment member 11 of the blade 9 and is attached so that the blade of the blade 9 can be moved up and down in a direction perpendicular to the center line of the recess 3. The blade 9 is larger than the width of the suppository to be divided. The blade 9 is moved along the rod-shaped member 10 and stopped at a required division position scale mark, and the suppository previously placed in the recess 3 is cut by the blade 9. The suppository split scale and the suppository cutting blade are made more convenient as an integrated structure.

  In particular, the use of suppositories for children who are highly responsive to drugs requires that some of the suppositories be divided and administered in an appropriate amount, which makes it easy to divide the appropriate amount not only in specialists such as pharmacies but also at home. And the importance of providing means that can be done accurately is great.
