Description

Water aqua wiping and dosing device

Technical Field

The invention relates to a medical administration device, in particular to a water aqua wiping administration device suitable for large-area smearing.

Background

Most skin patients need to be treated by wiping water, but the current clinical use is a writing brush type wiping device provided by manufacturers, and the brush hair is hard and brings great discomfort to the patients; and is not conducive to cleaning, presenting an increased risk of infection; meanwhile, the use steps are more, which brings great inconvenience to the patient who rubs the medicine; the use amount of the medicine is not easy to control by the brush pen type medicine wiping method, and the use effect of the medicine is influenced to a certain extent.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and solve the problems of troublesome wiping and administration of the aqueous solution and uneven large-area application.

In order to achieve the purpose, the invention provides a water aqua wiping drug delivery device, which comprises a drug cylinder, a piston and a sponge strip, wherein one end of the drug cylinder penetrates into the piston, and the outlet at the other end of the drug cylinder is communicated and fixed to the center of the sponge strip through a hard conduit; the positions of the sponge strips close to the two ends are communicated and fixed to the outlet at the other end of the medicament cylinder through an elastic conduit.

The sponge strip is strip-shaped and has certain water storage capacity. The inner wall of the medicament barrel is matched with the piston, so that the medicament can be extruded from the outlet at the other end under the pushing of the piston. The hard catheter is not easy to deform, the elastic catheter generates recovered stress after elastic deformation, the hard catheter can be made of glass, hard plastic and the like, and the elastic catheter can be made of rubber tubes, metal tubes with elasticity and the like.

Preferably, the sponge strip is in the shape of an arch protruding towards the medicament cartridge.

When the arched shape of the sponge strip is used, the concave arc-shaped surface faces towards the human body, and the convex arc-shaped surface faces towards the user.

Preferably, the elastic conduit is in a pressed bent shape after the fixation is finished.

The term "compressed and bent" as used herein refers to a state in which the patient is relatively straightened in its relaxed state, i.e., the patient is pre-stressed after fixation is complete.

Preferably, the medicament barrel and the hard catheter form an included angle of 45 degrees.

The included angle between the medicament barrel and the hard conduit is the included angle between the length direction of the medicament barrel and the length direction of the hard conduit.

Preferably, the distance from the connection point of the elastic conduit on the sponge strip to the nearest end of the sponge strip is a, the distance from the connection point of the elastic conduit on the sponge strip to the center of the sponge strip is b, and then b is 2 a.

The nearest end of the sponge strip referred to herein is the end of the sponge strip closest to the connection point of the elastic catheter on the sponge strip. The center of the sponge strip is the communication part of the hard conduit.

Preferably, the medicament barrel is externally sleeved with an anti-slip rubber sleeve.

The anti-slip rubber sleeve is made of anti-slip rubber, and anti-slip patterns can be arranged on the surface of the anti-slip rubber sleeve.

Preferably, the tail part of the piston is provided with a handle which is convenient for pressing and conveying the medicament in the medicament barrel.

The handle is fixed to one end of the piston through a connecting rod and is perpendicular to the piston.

Preferably, the medicament cylinder wall is made of transparent materials, and scales for indicating the medicament consumption degree are further arranged on the medicament cylinder wall along the length direction.

Hard pipe and elasticity pipe with the medicament direction sponge strip in the medicament section of thick bamboo to relative position through the fixed sponge strip of hard pipe and a medicament section of thick bamboo, make the sponge strip produce through the elasticity pipe and warp, can laminate the human body more with the both ends of sponge strip when making the sponge strip press on the human body.

Through adopting the arched sponge strip, the sponge strip is easier to deform the two ends of the sponge strip when contacting the human body, thereby extruding the medicament.

The elastic conduit in the prestressed state gives deformation pressure to the sponge strip, so that the sponge strip is easier to deform two ends of the sponge strip when being attached to a human body, and the medicament is extruded by pressing.

Through the medicament section of thick bamboo with the contained angle that sets up between the stereoplasm pipe, the application of force is paintd in the handheld of being convenient for, also makes things convenient for the use at narrow position simultaneously.

The connecting points of various catheters on the sponge strip are arranged, so that the integral filling degree of the medicament in the sponge strip is improved.

Through setting up anti-skidding rubber sleeve, promote the hand of gripping of medicament section of thick bamboo, avoid in use to overturn.

Through the arrangement of the handle, a user can simply control the pushing handle to control the filling rate of the medicinal preparation in the sponge, and the sponge is labor-saving and good in effect.

The invention has the advantages that the comfort level of the patient can be greatly improved; the cleaning is convenient, the infection risk is reduced, and the rubbing time is saved by large-area smearing; can better control the dosage of the medicine and improve the curative effect of the medicine.

Detailed Description

The invention is further described below with reference to the following figures and specific examples.

The water aqua wiping drug delivery device shown in fig. 1 to 3 comprises a drug cylinder 1, a piston 2 and a sponge strip 3, wherein one end of the drug cylinder 1 penetrates into the piston 2, and the outlet of the other end of the drug cylinder 1 is communicated and fixed to the center of the sponge strip 3 through a hard conduit 4; the positions of the sponge strips 3 close to the two ends are communicated and fixed to the outlet at the other end of the medicament barrel 1 through an elastic conduit 5. And an included angle of 45 degrees is formed between the medicament cylinder 1 and the hard conduit 4. The medicament barrel 1 is externally sleeved with an anti-slip rubber sleeve 7. The tail part of the piston 2 is provided with a handle 6 which is convenient for pressing and conveying the medicament in the medicament barrel. The wall of the medicament barrel 1 is made of transparent materials, and the wall of the medicament barrel 1 is also provided with scales 8 for indicating medicament consumption degree along the length direction.
