Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a neonatal atomization drug delivery device.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] See attached Figure 1 -Attached Figure 7 A neonatal nebulizer drug delivery device comprises an outer tube 1, a drug-loading cartridge 2 and an atomizing mask 5. The top end of the drug-loading cartridge 2 is threadedly connected with a cartridge cover 3. The drug-loading cartridge 2 is inserted into the outer tube 1. A through hole is penetrated through the bottom of the outer tube 1. A mist outlet connector 4 is fixedly installed through the outer surface of the drug-loading cartridge 2. A hose 6 which is mutually conductive can be detachably installed between the mist outlet connector 4 and the atomizing mask 5. A waist-shaped groove 8 is penetrated through the outer surface of the outer tube 1. The mist outlet connector 4 is arranged through the waist-shaped groove 8. An oxygen inlet connector 7 which is connected to the inside of the drug-loading cartridge 2 is installed at the bottom. A nebulizer 19 is fixedly installed on the bottom wall of the drug-loading cartridge 2. A weight detection mechanism is installed between the outer tube 1 and the drug-loading cartridge 2.

[0028] In this embodiment, the weight detection mechanism includes a support spring 23 fixedly installed between the bottom wall of the outer cylinder 1 and the bottom end of the drug-filled cylinder 2, a gas cut-off component is installed between the drug-filled cylinder 2 and the oxygen inlet joint 7, the gas cut-off component includes a connecting pipe 14 fixedly installed at the bottom of the drug-filled cylinder 2, and the connecting pipe 14 is connected to the inside of the drug-filled cylinder 2, and a mutually conductive sealing box 9 is fixedly installed between the bottom end of the connecting pipe 14 and the oxygen inlet joint 7, and the two end portions of the sealing box 9 are open structures, and sealing blocks 10 are slidably installed inside the two ends of the sealing box 9, and the end of the sealing block 10 away from the sealing box 9 is an inclined surface setting, and a reset component is installed between the sealing block 10 and the sealing box 9, and the reset component includes a mounting groove 11 that penetrates and is opened on the upper surface of the sealing block 10, and the inner walls of the two ends of the sealing box 9 are fixedly installed with a fixing plate 12, and the fixing plate 12 is arranged on the inner side of the mounting groove 11, and a spring rod 13 is fixedly installed between the fixing plate 12 and the inner wall of the mounting groove 11 away from the sealing box 9, and a conductive component is installed between the two sealing blocks 10 and the sealing box 9.

[0029] As the medicine in the medicine cartridge 2 is continuously atomized and discharged from the atomizing mask 5, the medicine will gradually decrease, so that the weight of the medicine cartridge 2 will continue to decrease, and the medicine cartridge 2 will gradually move upward under the elastic force of the supporting spring 23. When the medicine cartridge 2 drives the sealing box 9 to move upward synchronously through the connecting tube 14, the inclined surfaces at both ends of the sealing block 10 will abut against the side edges of the through hole opened at the bottom of the outer tube 1, so that the sealing block 10 can move toward the inside of the sealing box 9 when squeezed. After the medicine in the medicine cartridge 2 is used up, the two relatively moving sealing blocks 10 can cut off the connection between the connecting tube 14 and the oxygen inlet connector 7, thereby blocking the external oxygen from continuing to be transmitted to the atomizing mask 5, thereby preventing the newborn from irritating the respiratory tract due to long-term inhalation of high-concentration oxygen, causing coughing or other respiratory discomfort.

[0030] In this embodiment, the conductive component includes a conductive block 15 fixedly mounted on the outer surface of the sealing box 9, a spring 16 is fixedly mounted on the side of the sealing block 10, and a conductive contact 17 is fixedly mounted on the outer surface of the spring 16 near the conductive block 15, and the spring 16 is against the outer surface of the conductive block 15. A heating wire 20 is embedded in the inner wall of the drug cartridge 2 near its bottom, and an alarm light 21 is fixedly mounted on the outer surface of the outer cylinder 1. The heating wire 20, the alarm light 21, the spring 16 and the conductive contact 17 are electrically connected to the external power supply, and a limit card strip 18 is fixedly mounted on one end of the spring 16 away from the sealing block 10, and the limit card strip 18 is used to limit the spring 16 to prevent the spring 16 from falling off; the control mode of the electrical component in this scheme is controlled by an external controller matched therewith, and the control circuit can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field, and is only used without improvement, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control mode and circuit connection in detail.

[0031] When a certain amount of liquid medicine is loaded, the conductive contact piece 17 contacts the conductive block 15, and can conduct the electrical connection between the heating wire 20, the external oxygen supply equipment, the alarm light 21 and the external power supply, so that the heating wire 20 can heat the liquid medicine in the medicine cartridge 2, so that the atomized liquid medicine and the oxygen sent into the atomizing mask 5 can maintain a certain temperature, thereby preventing the newborn from inhaling supercooled gas and causing respiratory discomfort; at this time, the external power supply is connected to the alarm light 21, and the battery inside the alarm light 21 can be charged. After the conductive contact piece 17 is no longer in contact with the conductive block 15, the alarm light 21 will sound an alarm through the power of the battery to remind the medical staff that the nebulization treatment of the newborn is completed, so that the medical staff can remove the nebulizer mask 5 from the newborn's face in time; when the two sealing blocks 10 move relative to each other, the spring sheet 16 will be driven to move synchronously, so that the conductive contact sheet 17 installed on the spring sheet 16 is disconnected from the conductive block 15 installed on the outer side of the sealing box 9, so that the conductive block 15 and the conductive contact sheet 17 disconnect the power supply of the external oxygen supply equipment, so that the external oxygen supply equipment stops the oxygen supply operation, and disconnects the power supply of the heating wire 20 in the medicine cartridge 2, and stops the heating operation of the heating wire 20.

[0032] In this embodiment, an observation groove 22 is formed through the outer surface of the outer tube 1 near its bottom, so that medical personnel can observe the liquid level of the medicine added to the medicine cylinder 2 through the observation groove 22; a fixing clip 24 is fixedly installed on the outer surface of the outer tube 1 on the side opposite to the observation groove 22.

[0033] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the oxygen inlet connector 7 is connected to the external oxygen supply device through the connecting pipe, and the medicine-filled cartridge 2 and the outer cartridge 1 filled with medicine liquid are fixedly connected to the nursery bed through the fixing clip 24, and then the atomizing mask 5 is placed on the mouth and nose of the newborn, so that the atomizer 19 installed inside the medicine-filled cartridge 2 is operated to atomize the medicine liquid inside the medicine-filled cartridge 2, and the atomized medicine liquid will enter the atomizing mask 5 driven by the external oxygen, so that the atomized medicine liquid can be inhaled into the body of the newborn, thereby achieving the atomization treatment effect;

[0034] As the liquid medicine in the medicine cartridge 2 is continuously atomized and discharged from the atomizing mask 5, the liquid medicine will gradually decrease, so that the weight of the medicine cartridge 2 will continue to decrease, and the medicine cartridge 2 will gradually move upward under the elastic force of the supporting spring 23. When the medicine cartridge 2 drives the sealing box 9 to move upward synchronously through the connecting tube 14, the inclined surfaces at both ends of the sealing block 10 will abut against the side edges of the through hole opened at the bottom of the outer tube 1, so that the sealing block 10 can move toward the inside of the sealing box 9 when squeezed. After the liquid medicine in the medicine cartridge 2 is used up, the two relatively moving sealing blocks 10 can cut off the connection between the connecting tube 14 and the oxygen inlet connector 7, thereby blocking the external oxygen from continuing to be transmitted to the atomizing mask 5, thereby preventing the newborn from irritating the respiratory tract due to long-term inhalation of high-concentration oxygen, causing coughing or other respiratory discomfort;

[0035] When a certain amount of liquid medicine is loaded, the conductive contact piece 17 contacts the conductive block 15, and can conduct the electrical connection between the heating wire 20, the external oxygen supply device, the alarm light 21 and the external power supply, so that the heating wire 20 can heat the liquid medicine in the medicine cartridge 2, so that the atomized liquid medicine and the oxygen sent into the atomizing mask 5 can maintain a certain temperature, thereby preventing the newborn from inhaling supercooled gas and causing respiratory discomfort; at this time, the external power supply is connected to the alarm light 21, and the battery inside the alarm light 21 can be charged. After the conductive contact piece 17 is no longer in contact with the conductive block 15, the alarm light 21 will sound an alarm through the power of the battery, reminding the medical staff that the atomization treatment of the newborn is completed, so that the medical staff can remove the atomizing mask 5 from the newborn's face in time;

[0036] When the two sealing blocks 10 move relative to each other, the spring sheet 16 will be driven to move synchronously, so that the conductive contact sheet 17 installed on the spring sheet 16 is disconnected from the conductive block 15 installed outside the sealing box 9, so that the conductive block 15 and the conductive contact sheet 17 disconnect the power supply of the external oxygen supply equipment, so that the external oxygen supply equipment stops the oxygen supply operation, and disconnects the power supply of the heating wire 20 in the medicine cartridge 2, and stops the heating operation of the heating wire 20.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
