Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to a multi-needle medicine dispensing peristaltic tube. Background Art

[0002] Infusion therapy has become a common medication method for patients and is widely used. During infusion therapy, the therapeutic drugs are mostly added to infusion bags or infusion bottles. Large hospitals have a large number of patients, so the number of infusions required every day is relatively large. Manual configuration is a large workload and prone to fatigue, so various drug configuration equipment came into being. The peristaltic pump dispensing machine currently sold on the market is a peristaltic pump installed with a peristaltic tube. The existing peristaltic tubes are designed with a configuration needle at both ends.

[0003] When configuring the same drug in large quantities, if the drug is a powder injection, it is necessary to first dissolve the powder injection one by one with the solvent in the infusion according to the dosage of each prescription, and then suck and add them one by one into the infusion bag or infusion. If the drug is a solution, it is sucked and added to the infusion one by one according to the prescribed dosage. When configuring the same drug in batches, if multiple drugs are added to the infusion at the same time, it is necessary to repeatedly puncture the infusion stopper to suck and transfer the liquid medicine. This operation will cause the stopper to peel off and produce particles due to multiple punctures. At the same time, repeated punctures of the stopper to suck the liquid medicine can easily cause contamination, affect the quality of configuration and bring potential harm to patients; at the same time, this repeated puncture and suction operation also brings repetitive labor to the configuration personnel, increases labor intensity, delays the configuration time, and affects the timely use of patients. This is especially prominent when centralized configuration is carried out in large intravenous drug preparation centers. Utility Model Content

[0038] In addition, the peristaltic tube 5 includes a peristaltic section 51, a configuration section 52 and an infusion section 53; one end of the peristaltic section 51 is connected to the configuration section 52, and the other end is connected to the infusion section 53, the infusion section 53 is connected to an infusion end, and the configuration section 52 is connected to a configuration end.

[0039] Furthermore, the length of the infusion needle can be greater than the thickest thickness of the commercially available infusion plug, and the needle shape and pinhole shape of the infusion needle are designed to be a side-hole porous needle or a bevel needle. The needle length, needle shape and pinhole shape of the dosing configuration vary depending on the type of configured medicine. When configuring vials of drugs, the needle length is the length that penetrates the thickest thickness of the vial plug. In this way, the needle length design at the configuration end of the vial is strictly controlled during design to ensure that the configured drug solution is completely aspirated without leaving any residue; the needle shape is a side-hole porous needle or a bevel needle. When configuring ampoules of drugs, the needle length is designed to be greater than the height of the corresponding configured drug solution ampoule after cutting, and does not touch the bottle mouth to ensure that no pollution is caused and it is easy to operate. The needle shape is designed to be a flat-headed porous needle.

[0040] It should be noted that if the peristaltic tube is used in conjunction with a peristaltic pump to manually configure vials of drugs, the needle at the configuration end of the peristaltic tube can be designed to be a needle with a tray. During manual configuration, several vials of drugs can be simultaneously inserted into the corresponding number of tray-configured needles. Due to the clamping of the tray, the simultaneous configuration of several drugs can be completed at one time; if ampoule drugs are configured, the needle length is designed to be greater than the height of the corresponding configured drug ampoule after cutting, and the top of the needle is designed to be a flat-headed multi-porous needle, and the multiple needle holes are evenly distributed at different locations on the top of the flat head of the needle or on the edge of the needle stem near the top of the flat head of the needle.

[0041] The pinhole shape of the side hole multi-porous needle can be a round hole with the outer opening facing upward and the inner opening facing downward, an elliptical hole or other inclined pinholes, so as to ensure that the liquid medicine flows down better without leaving any residual liquid. The length of the ampoule drug configuration needle is the height of the ampoule bottle left after cutting the ampoule bottle of different capacities. The specific ampoule bottle capacity is 2ml, 5ml, 10ml, 20ml, 30ml, etc.

[0042] Furthermore, the ends of all dosing needles or infusion needles are provided with needle protection covers to keep the needles sterile and clean and to prevent injuries caused by operating errors.

[0043] Furthermore, the peristaltic tube can be designed to be multi-section or integrally formed according to usage requirements to meet different usage requirements, and the needle seat can change its shape according to usage requirements to meet manual or machine usage requirements.

[0044] Furthermore, the peristaltic tube can be used for single-head peristaltic pumps, and can also be used for multi-head peristaltic pumps of intelligent rapid peristaltic dispensing machines. Among them, the length of the needle at the infusion end is greater than the thickest thickness of the commercially available infusion rubber stopper, and can adapt to all infusion drugs. The length of the needle at the configuration end needs to be set according to the type of configured drug; when the vial drug is configured, the configuration end needle is designed as a side-hole multi-porous needle or a beveled single-hole needle; the multiple pinholes of the side-hole multi-porous needle are evenly distributed at different heights around the needle stem at the top of the needle, but the distance between the pinholes is closely connected to ensure that more than two pinholes are leaked after puncturing the thickest rubber stopper of the commercially available vial. The bevel of the beveled single-hole needle is designed to be a long bevel, and the length of the beveled single-hole needle is to ensure that more than two-thirds of the beveled pinhole is exposed after puncturing the thickest rubber stopper of the commercially available vial. When dispensing vials of drugs, the vials are inverted, so the length of the needle at the dispensing end of the vial is strictly controlled during design, and a pinhole is reserved on the needle stem below the thickest stopper to ensure that when the thinnest stopper of the vial is dispensed, the liquid is completely aspirated without leaving any residue, and an appropriate dispensing speed is maintained. When dispensing ampoules of drugs, the top of the needle is designed to be a flat-headed multi-porous needle, and multiple pinholes are evenly distributed at different locations on the top of the flat needle or on the edge of the needle stem near the top of the flat needle. The length of the needle for ampoule drugs is designed to be greater than the height of the corresponding ampoule of drug solution after cutting, for example, the ampoule capacity is 5ml, 10ml, 20ml, 30ml, etc.

[0045] Furthermore, the infusion section of the peristaltic tube is provided with a filter to prevent particles such as rubber stopper desquamation and glass residue from entering the infusion solution and causing harm to the human body while ensuring smooth drug solution configuration. The peristaltic tube may not be provided with a filter when it affects the stability of the drug dosage form and the configuration speed according to differences in drug properties.

[0046] The multi-needle medication dispensing peristaltic tube provided by the present invention can be configured for manual use with a single-head peristaltic pump. If the drugs are vials of the drug class, needle opening and closing type holders can be set on the needle seats at both ends of the peristaltic tube. When configured in this way, due to the locking of the needle opening and closing type holders, several vials of drugs can be locked at the same time, and the holder at the other infusion end can lock the rubber plug of the infusion. A bracket can also be made to match, and multiple needles of the holder can be fixed on the bracket, and the peristaltic pump can be started to make the configuration smoother and implement the configuration smoothly. If multiple ampoule drugs are configured at the same time, the infusion configuration needle is designed as an opening and closing type holder needle, and the configuration end is a multi-head flat-head multi-porous needle configured for the ampoule class. An ampoule placement bracket can be made, and the multi-head flat-head multi-porous needle configured for the ampoule class can be matched, and the peristaltic pump can be started to make the simultaneous configuration of multiple ampoule drugs smoother.

[0047] The multi-needle medication dispensing peristaltic tube provided by the present invention is installed in the intelligent peristaltic pump dispensing machine when in use, and used in conjunction with the intelligent peristaltic pump dispensing machine. When configuring, the multi-needle peristaltic tube is matched with the card according to the number of peristaltic pump heads and in the peristaltic pump, the card holder of the infusion opening and closing card holder needle at the infusion configuration end and the needle on the infusion rubber plug are inserted into the infusion rubber plug; the configuration end needle seat card and the configuration needle seat card rack are inserted into the corresponding configuration drug splint card and the configuration drug rubber plug. After the installation is completed, the intelligent peristaltic pump dispensing machine is turned on to complete the simultaneous configuration of multiple drugs in multiple infusions in one batch, which can greatly improve work efficiency, reduce pollution, and improve configuration quality. At the same time, a filter is added to effectively filter out the particles generated during the drug configuration process, and the ordinary configuration is innovated into a filtration configuration, which greatly improves the configuration quality.

[0048] The multi-needle dispensing peristaltic tube provided by the new invention can not only be used in conjunction with the multi-head peristaltic pump of the intelligent rapid peristaltic dispensing machine, but can also be adapted to the use of a single-head peristaltic pump. The newly designed multi-needle dispensing peristaltic tube has a needle at the end connected to the infusion, and multiple needles at the end connected to the configured medicine. Such an innovative design can implement the one-time configuration of multiple drugs. At the same time, the design of needles with different specifications and configurations is adapted to the configuration requirements of different numbers (doses) of configured medicines caused by different dosages of configured prescription drugs and different types of medicine bottles with different shapes. In this way, multiple drugs in multiple bags (bottles) of infusion can be configured in batches at the same time, reducing the number of configurations, reducing the risk of particles and contamination caused by repeated puncture and suction of the drug solution, reducing labor intensity, reducing configuration time and improving configuration quality. At the same time, a filter is added to effectively filter out the particles generated during the drug configuration process, and the ordinary configuration is innovated into a precision filtration configuration, which greatly improves the configuration quality.
