Description

A kind of applicator

Technical field

This utility model relates to field of medical products, smears the applicator of liquid medicine when relating in particular to a kind of the operation in the body.

Background technology

Minimally Invasive Surgery is meant the operation that modern medical equipment such as utilizing peritoneoscope, thoracoscope and relevant device carry out; Minimally Invasive Surgery need not be operated on; Only need open 1-3 0.5-1 centimetre aperture on one's body patient, patient's preventing from scar, painless, only need just can accomplish inspection, treatment, rehabilitation overall process in 3-5 days.Minimally Invasive Surgery has reduced the injury of traditional operation to human body, has greatly reduced inconvenience that disease brings to the patient and painful.Advantage such as Minimally Invasive Surgery has that wound is little, light pain, recovery are fast more and more receives doctor or patient's welcome.When Minimally Invasive Surgery, usually need to smear liquid medicine, to carry out antiinflammatory, pain relieving and sterilization etc. toward the interior a part of body.But,, very inconvenient toward the interior coating of body because the Minimally Invasive Surgery wound is little.Cotton swab is the present normally used means that is coated with, but coating in the body when being not suitable for being used in Minimally Invasive Surgery very much, the one, because cotton swab bar is relatively shorter and be rigidity; Smear distance and the direction strictness is limited, the 2nd, because that cotton swab absorbs the liquid medicine amount is limited, in the occasion of smearing or need more liquid medicine than large tracts of land; Cotton swab need repeatedly pass in and out the wound dosing or use many cotton swabs instead; Inconvenient operation, coating efficient are low, and cotton swab pass in and out at every turn wound all can grazing to wound, increased patient's misery.

Summary of the invention

The purpose of this utility model is, a kind of applicator of being convenient to when operation coating in the body is provided.

To achieve these goals, the applicator that this utility model provides comprises the interior pipe of being made by flexible material, and an end of interior pipe is provided with the coating head of being made by water absorbing material.

The applicator that this utility model provides, interior pipe by the flexible material manufacturing and can make long, unrestricted on distance and direction during toward the interior coating of body, can arrive Anywhere intravital; And liquid medicine can constantly offer the coating head through interior pipe in coating, and the coating head only needs disposable turnover wound, and is easy to use, coating efficient high and alleviated patient's misery.

Further; Applicator also comprises body, ejector sleeve and the outer tube of being made by flexible material, and ejector sleeve can be arranged on the body with moving around, and ejector sleeve has cavity; One end of outer tube connects body; Interior pipe is in outer tube, and the other end of interior pipe connects ejector sleeve and is communicated with cavity, and the radial dimension of coating head is less than the diameter of outer tube.When not using, retract the coating head in the outer tube through ejector sleeve, the coating head is avoided being polluted and damaging in the protection of outer tube, makes applicator much cleaner, safer.

Below in conjunction with accompanying drawing this utility model is described in detail.

The specific embodiment

Referring to Fig. 3 and Fig. 4; Interior pipe 4 is enclosed within the outer tube 3; In pipe 4 and outer tube 3 by such as flexible material manufacturings such as plastics, silica gel and rubber; Flexible well can be crooked, diameter can do smallerly but length can be done longly, interior pipe 4 can pass the very little wound of Minimally Invasive Surgery and arrive Anywhere intravital with outer tube 3.Referring to Fig. 5; One end of interior pipe 4 is provided with needle tubing 6, and applying head 5 is inserted on the needle tubing 6, can make things convenient for and be arranged on applying head 5 securely an end of interior pipe 4 like this; And the syringe needle of needle tubing 6 is probably at the medium position of applying head 5, and the liquid medicine that comes out from syringe needle can be absorbed by applying head 5 fully.Applying head 5 is roughly cylindric, and its radial dimension, can retract applying head 5 in the outer tube 3 when not using less than the diameter of outer tube 3, to prevent polluting and damage not only health but also safety.Applying head 5 mainly is used for absorbing liquid medicine, is coated onto lesions position to liquid medicine again, so applying head 5 is by the water absorbing material manufacturing; For example Cotton Gossypii, sponge and foam etc.; Because the foam good water absorption expands greatlyyer after the suction, and material softness; Do not stay residue after smearing, applying head 5 preferred employing foam manufacturings.

Referring to Fig. 3 and Fig. 4, an end of outer tube 3 connects body 1, and body 1 has the tube chamber of hollow, and an end of ejector sleeve 2 is in this tube chamber, and ejector sleeve 2 is roughly the tubulose of hollow, and the center has column cavity 21, and the other end of interior pipe 4 connects ejector sleeve 2 and is communicated with cavity 21.

Referring to Fig. 6; Ejector sleeve 2 is provided with two microscler raised lines 22 that extend along its length direction on its outside wall surface; Body 1 is provided with two elongate recesses 12 of extending along its length direction on the wall of the chamber of its tube chamber; Raised line 22 is in groove 12 and can move around along groove 12, and the cooperation of groove 12 and raised line 22 not only can reciprocatingly be arranged on ejector sleeve 2 on the body 1; And confirmed the relative position of body 1 and ejector sleeve 2 in a circumferential direction, ejector sleeve 2 relative bodies 1 can only can not rotate in a circumferential direction moving axially.When not using, retract coating head 5 in the outer tube 1 through ejector sleeve 2, coating head 5 is avoided being polluted and damaging in the protection of outer tube 1, makes applicator much cleaner, safer.

Referring to Fig. 4 and Fig. 6, body 1 is provided with two microscler through holes 13 of its wall of the lumen of perforation, and an end of ejector sleeve 2 pipe 3 in connecting is provided with two convexities 23, and protruding 23 are the wedge shape that on the end, rises, and protruding 23 also can move around along through hole 13 in through hole 13.Protruding 23 with the cooperating of through hole 13, can prevent when pulled backwards ejector sleeve 2, to be pulled away from body 1 to ejector sleeve 2, and can clip convexity 23 relatively with instrument and separate body 1 to ejector sleeve 2.

Referring to Fig. 1 and Fig. 3; The outer wall of body 1 is provided with the stop part 14 of a pair of outside protrusion; Two stop parts 14 are distributed in same diametric two relative position places, and during use, two fingers are being pinched body 1 near stop part 14 positions; When promoting ejector sleeve 2 forward, stop part 14 can prevent these two fingers body 1 that slips away.Referring to Fig. 2 and Fig. 6, the outer wall of ejector sleeve 2 is provided with the projection 24 of a pair of outside protrusion, and projection 24 protrudes from the outward flange of body 1, and projection 24 is mainly used in and conveniently pulls back ejector sleeve 2.Stop part 14 is vertical with projection 24, and the both hands cooperation when helping using improves comfort.

When not using, applying head 5 is in outer tube 3.During use; Outer tube 3 is got in the body from wound, add liquid medicine in the cavity 21 of ejector sleeve 2 then, promote ejector sleeve 2 simultaneously forward; Release outer tube 3 to applying head 5; Liquid medicine flows to applying head 5 from ejector sleeve 2, interior pipe 4 and needle tubing 6 successively, moves to the position that need smear to applying head and carries out coating, in body, takes out outer tube 3 and interior pipe 4 together after last coating is accomplished.
