Detailed Description

In order to make the technical solution and the advantages of the present invention more clearly understood by those skilled in the art, the present invention is further illustrated in the following drawings and detailed description, but the detailed description is not limited to the following specific structures:

the embodiment provides a pressure device for anorectal administration, which can be inflated manually to cut the body and sense the pressure in real time, is safe and reliable, and overcomes the defect that medical workers are difficult to sense the real-time pressure in person when automatic inflation equipment is adopted, and the problem of danger easily occurs when the inflation device breaks down. Specifically, the inflator of the present embodiment is designed in the following structure: as shown in fig. 1-2, it comprises a compressible hollow bladder 7, which can be made of a material with elasticity according to the actual compression. The bag body 7 is provided with an air nozzle (not shown) for injecting compressed air, and the front end of the bag body 7 is provided with a pressure pipe 8 embedded in the bag body 7, of course, the pressure pipe 8 can be integrally formed with the bag body 7. An arc spout 701 has been seted up inside the lateral cyst wall in utricule 7 front end, pressure pipe 8 runs through this arc spout 701, and sliding fit has with it the adaptation with be curved strip slide 9, has seted up a through hole 702 on the slide 9, and slide 9 one end is connected with the bow spring 10 in the arc spout 701, and the other end is connected with the dwang 11 that stretches into utricule 7, dwang 11 articulates on articulated shaft 12 in utricule 7 and articulated shaft 12 is located slide 9's centre of a circle department, the one end that slide 9 was kept away from to dwang 11 articulate has the depression bar 13 of a vertical setting, and this depression bar 13 one end is articulated with dwang 11, and the other end passes behind the cyst wall and stretches out outside utricule 7, and sliding seal cooperation between depression bar 13 and the utricul. The compression bar 13 is connected to the inner wall of the capsule body 7 through a return spring 14 to realize the return of the compression bar 13 in a non-inflation state, or/and the rotating rod 11 is connected with the hinge shaft 12 through a torsion spring 15, the torsion spring 15 drives the rotating rod 11 in the non-working state to return to drive the sliding plate 9 to cut off the air outlet channel in the inflation pipe 8, namely, the torsion spring 15 and the return spring 14 can be selected optionally or simultaneously. When in use, the bag body 7 is filled with rated compressed air in advance, and the bag body 7 is provided with an air nozzle similar to an air inflation hole structure or a bicycle tire air nozzle, preferably an air inflation hole structure such as a basketball air inflation hole, which is not described in detail herein. In addition, a connecting hose (not shown in the figure) is connected to the bag body, the connecting hose is communicated with a low-pressure air source through a leather hose (not shown in the figure), a switch valve (not shown in the figure) is arranged on the leather hose so that the bag body can be inflated under the condition of having the compressed air source, the bag body at the moment is equivalent to a manual switch to control outward deflation, and the purpose is still to manually sense the pressure and reasonably adjust the output air flow.

When the inflatable bag is used, an operator holds the bag body 7 by hand, presses the pressing cap at the top end of the pressing rod 13 by a thumb to press the ejector rod downwards, the ejector rod drives the rotating rod 11 to do lever motion, and because the hinged shaft 12 is positioned at the circle center of the sliding plate 9 and is concentric with the sliding plate, when the sliding plate 9 rotates around the circle center to the process that the through hole 702 of the sliding plate is crossed and overlapped with the pipe hole of the charging pipe 8, the external charging can be realized, and the charging pipe 8 is connected with the air pipe 5. It should be further noted that, in this embodiment, it is also important that the size difference between the through hole 702 of the sliding plate 9 and the pipe hole of the charging pipe 8 is as large as possible, because it is ensured that the sliding plate 9 moves to have the through hole 702 in cross communication with the pipe hole of the charging pipe 8 for a longer time so as to be fully charged through the charging pipe 8. In the schematic diagram of fig. 2, the size difference between the through hole 702 and the tube hole of the pressure tube 8 is drawn to be small, and in actual manufacturing, for example, the through hole 702 may be preferably processed into an arc-shaped strip hole structure in accordance with the bending direction of the sliding plate 9, so as to adapt to the length direction (bending direction) of the sliding plate 9 on the one hand, and greatly increase the time for the through hole 702 to be communicated with the tube hole of the pressure tube 8 when the sliding plate 9 slides, thereby ensuring that the pressure tube 8 provides sufficient inflation air pressure for medical instruments such as external anorectal administration devices.

Of course, the structure for inflating the bladder 7 may be designed as follows: referring to fig. 3, a unidirectional air inlet component is additionally installed at the other end of the balloon 7 to realize air supply and storage of the balloon 7 at any time, the unidirectional air inlet component includes a driving plate 24, a driving rod 18, a gate plate 19, a guide rod 21, a jacking spring 22, a fixing rod 23 and an inlet pressure pipe 20, the inlet pressure pipe 20 is embedded in the rear end of the balloon 7 in a penetrating manner, and the driving plate 24 is fixedly connected to one side of the rotating rod 11 facing the rear end of the balloon 7. One end of the driving rod 18 keeps smooth contact with the driving plate 24, the other end of the driving rod is connected with the gate plate 19, one end of the gate plate 19, which is far away from the driving rod 18, is provided with a pair of guide rods 21 which are arranged at intervals and in parallel, the two guide rods 21 are respectively inserted into the pipe wall of the pressure inlet pipe 20 and can freely slide in the pipe wall, the top bracing spring 22 is further arranged between the two guide rods 21, one end of the top bracing spring 22 is connected to one end of the gate plate 19, which is far away from the driving rod 18, the other end of the top bracing spring 22 is connected to the fixing rod 23 fixedly connected into the pressure inlet pipe 20, and the top bracing spring 22 props the. When the compression bar 13 is pressed down to drive the rotating rod 11 to rotate, the driving plate 24 extrudes and pushes the driving rod 18 to move axially, so that the gate plate 19 seals the port of the pressure inlet pipe 20, and meanwhile, the rotating rod 11 drives the sliding plate 9 to open the pressure inlet pipe 8, so as to realize external inflation. When the pressing rod 13 is released, all the components are reset, the flashboard 19 is jacked open by the jacking spring 22, the sliding board 9 seals the pressurizing pipe 8, and external air enters the capsule body 7 to realize the air supplement of the capsule body 7. Further, if necessary, if the whole body of the bag body 7 is too long, the driving rod 18 may be additionally provided with a plurality of coaxially arranged shaft sleeves (not shown in the figure) for supporting the bag body to slide, the shaft sleeves are fixed on a central axis in the bag body 7 through inner ribs (not shown in the figure), the inner ribs are fixedly connected to the inner wall of the bag body 7, and at the moment, the bag body 7 is pressed in a manner that two sides are squashed and is not suitable for being held by hands; of course, the driving rod 18 may be made of a lightweight material and a plastic material with a low density, and the place where the driving rod contacts the driving plate 24 is a smooth metal ball partially embedded in plastic to improve wear resistance and reduce friction, while the guide rod is made of a metal material to maintain the sliding stability of the driving rod 18 in a cantilevered configuration.

In the above structure of the unidirectional air intake component, a key design detail needs special attention: since the plunger 13 cannot be further depressed after the driving rod 18 pushes the shutter 19 against the end surface of the push pipe 20, the bladder 7 cannot be further compressed by a large amount over the entire surface, and the inflation capacity is linearly decreased. In order to make the driving rod 18 push the gate plate 19 to the end surface of the pressure pipe 20, the bladder 7 still has an integral overall compression amount, the driving rod 18 is specially processed to have an elastic telescopic structure, but the elasticity of the driving rod 18 is lower than that of the supporting spring 22, namely, when the driving plate 24 is in pressing contact with the driving rod 18, the supporting spring 22 is contracted violently, and the driving rod 18 is obviously shortened step by step after the gate plate 19 pushes the end surface of the pressure pipe 20 to adapt to the further rotation of the driving plate 24, so that the problem that the bladder 7 cannot be pressed down fully further is avoided ingeniously. In specific implementation, the driving rod 18 may be made into a two-section socket structure (not shown), one end of one section of the driving rod is inserted into a blind hole axially formed in the end of the other section of the driving rod, and a pressure-bearing spring with elasticity weaker than that of the top-supporting spring 22 is installed in the blind hole, and one end of the one section of the driving rod is connected to the pressure-bearing spring after extending into the blind hole, so that the driving rod is shortened when the pressure-bearing spring is compressed. Of course, the present embodiment may also adopt other structure forms of the elastic telescopic rod in the prior art, which meet the above requirements.

Above this kind of one-way part of admitting air installs back on utricule 7, can be convenient for medical personnel inflate annular inflation chamber 4 at any time, because handheld pressing has the perception effect of cutting one's body, can be convenient for know the pressure size, compare in some constant pressure valve control commonly used compressed air will safe and reliable much more, and simple structure, the volume is less, portable can pass through the connection such as rope at the tip of dosing pipe's back end 2. In some cases, for example, when the sliding path of the sliding plate needs to be large, or the device is inflated to the outside with a large amount of air and needs to compress the capsule 7 in a large amount, the front end and/or the rear end of the capsule 7 are made of hard or weak-elasticity plastic to ensure that the sliding plate 9 can slide stably and freely, or the part of the capsule 7 except for the area where the arc-shaped sliding groove 701 and the pressure inlet tube 20 are located is made of elastic material, and when the external inflation operation is performed, the medical staff holds or presses the part between the two ends of the capsule 7 as much as possible.

In addition, in order to more vividly illustrate the inflation and pressurization of the present invention suitable for specific clinical medical instruments, and to better highlight the technical idea and the actual existing application and effects thereof, the present embodiment also particularly provides a specific anorectal administration device, which requires the inflation device of the present invention to inflate air for realizing the fixed installation in the anorectal. In other words, the above-mentioned specific application can be practically matched to form a specific anorectal auxiliary treatment device, which comprises the anorectal administration pressurizing device of the present invention and a medicine soaking device, wherein the medicine soaking device comprises an expansion body which can be plugged into the anorectal, the expansion body comprises an outer surface layer and an inner core body, the surface layer has elasticity, and a pore is left between the surface layer and the core body, and the pore is used for filling air to expand the surface layer so as to enlarge the expansion body. The inner part of the core body is provided with a channel for external liquid medicine to flow in, the outlet end of the channel is communicated with the administration hole formed in the surface layer, and when the expansion body expands and becomes larger, the peripheral part of the hole edge of the administration hole protrudes out of the surface of the expansion body to form a cofferdam. Specifically, the medicine infusion device has the following specific structure:

this kind of anus intestines are with device of dosing, promptly soak medicine device, mainly include the inside pipe of dosing that is equipped with the passageway of dosing that supplies the liquid medicine to flow through, as shown in fig. 4, the pipe of dosing is divided into anterior segment 1 and back end 2, its anterior segment 1 is used for inserting within the anus intestines and the passageway bottom of dosing of anterior segment 1 is sealed and the lateral wall has a

medicine hole

101, 2 external surfaces of its back end have a plurality of scale marks along length direction to mark the length that inserts the anus intestines of dosing pipe, this back end 2 preferably chooses soft close skin material to make for use, and should also make the surface of back end 2 smooth as far as possible, so that insert. In the administration tube of the present embodiment, the exterior of the front section 1 is fixedly covered with a bullet-shaped hollow elastic sleeve 3 having elasticity, i.e. the front end is tapered and the rear end is cylindrical, the surface of the elastic sleeve 3 is preferably slightly smooth, i.e. the front section 1 and the elastic sleeve 3 together serve as the expansion body, and the drug outlet hole 101 serves as the outlet end of the core body (serving as the front section 1) having a channel for the external drug to flow into. One end of the elastic sleeve 3, which is far away from the warhead 301, is fixedly sleeved on the surface of the front section 1, and the direction of the warhead 301 of the elastic sleeve 3 is tightly sleeved at the free end of the front section 1 and the free end is integrally embedded into the side wall at the center of the warhead 301 of the elastic sleeve 3. The elastic sleeve 3 faces the side wall of the medicine outlet hole 101 and is provided with a medicine outlet barrel 304 integrally and convexly towards one side of the medicine outlet hole 101, namely, the medicine outlet barrel 304 can be integrally formed by adopting the same material. One end of the medicine outlet tube 304 is connected to the medicine outlet hole 101, the other end (as the medicine feeding hole) penetrates through the side wall of the elastic sleeve 3 and is used for contacting with the inner wall of the anorectal intestine and feeding medicine, and an annular expansion cavity 4 for containing air is formed between the elastic sleeve 3 and the front section 1 of the medicine feeding tube, namely, a hole is reserved between the surface layer and the core body, so that all parts of the side wall of the elastic sleeve 3 can be expanded radially as much as possible. Meanwhile, in order to supply compressed air and liquid medicine, the anorectal administration pressurizing device of the embodiment further comprises an air pipe 5 for conveying the compressed air, wherein the air pipe 5 is laid inside the administration pipe along the length direction of the administration pipe, one end of the air pipe 5 extends into the annular expansion cavity 4, and the other end of the air pipe 5 extends out of the rear section 2 of the administration pipe and then is connected with an inflating device, preferably, the inflating device is an air bag or an inflator which is inflated by manual pressing so as to timely press and inflate the air bag or the inflator. In the above embodiment, the air and the chemical liquid may be supplied by other means for supplying the chemical liquid and the compressed air, but it is preferable that the air and the chemical liquid are integrated into the wall of the administration tube in consideration of the convenience of use and storage due to the concentrated routing of the distribution tube. In order to prevent the flowing-out liquid medicine from flowing back, the axis of the medicine outlet cylinder 304 and the axis of the elastic sleeve 3 form an obtuse angle, and the bottom of the administration channel of the administration tube front section 1 is in a spherical shape protruding upwards, so that on one hand, after the patient is put into the administration tube by the administration tube in a prone posture, the medicine cannot flow back into the administration channel immediately due to the inclined arrangement of the medicine outlet cylinder 304, and time is provided for the affected part to absorb the medicine; on the other hand, in some special administration occasions, if the medicine flow is large, the medicine liquid can be conveniently distributed and shunted when entering the bottom end of the administration channel, and the concentrated flushing splashing and the medicine liquid backflow after the part caused by the splashing is combined with the affected part are relieved. In addition, the medicine outlet hole 101 is located on the side wall around the bottom spherical surface 102 of the front section 1, and the spherical surface participates in forming a part of the hole wall of the medicine outlet hole 101, and the design mainly considers that the medicine liquid flows out of the medicine feeding channel as much as possible on the basis of relieving the concentrated scouring splashing, so that the waste of medicine liquid deposition is reduced, and the accuracy of the medicine feeding amount is ensured.

In order to avoid the liquid medicine from flowing out of the medicine output barrel 304 to be scattered to the parts other than the affected part, the elastic expansion degree at the outlet end of the medicine output barrel 304 is preferably larger than the other parts, that is, relatively speaking, the surface of the elastic sleeve 3 at the medicine output barrel 304 is bulged and protruded higher to form the cofferdam, which is in closer contact with and surrounds the affected part, and completely surrounds the affected part in the outlet end of the medicine output barrel 304. Specifically, the thickness of the cylinder wall of the drug outlet cylinder 304 gradually decreases from the two ends to the center, and the cylinder wall at one end facing the outside of the elastic sleeve 3 is thinner than the cylinder wall connected to the drug outlet hole 101. On the basis, the outer surface of the wall of the cartridge 304 is concave inwards, and the inner surface of the wall is concave outwards, so as to form a hyperbolic-like cross-sectional profile, which is transformed into an arc-shaped curve, i.e. the radii are R and R respectively. Thus, when the annular expansion cavity 4 expands, the expansion deformation of the medicine cylinder 304 is inevitably larger, and the medicine cylinder is contacted with the healthy inner wall surface around the affected part of the anorectal inner wall more closely. And furthermore, as shown in fig. 5, a straight line passing through the vertex Z of the bottom spherical surface 102 of the front section 1 and perpendicular to the axis of the elastic sleeve 3 intersects with the inner surface of the cylinder wall at the upper part; this structure mainly is that the liquid medicine level that strikes the production when gushing into the bottom surface of administering the passageway in order to the liquid medicine splashes the in-process and can not directly squirt to the affected part, but is blocked, the buffering by crooked arc section of thick bamboo wall, then on getting into the sunken arc section of thick bamboo wall of below, flows in the affected part steadily, realizes mildly dosing, and is particularly strong to the property of a medicine, needs the occasion of progressively gently dosing. In order to realize that the surface of the elastic sleeve 3 at the position of the medicine cylinder 304 is more bulged, namely is more sensitive to pressure change, the longitudinal section of the intersected part of the annular expansion cavity 4 and the medicine discharge cylinder 304 is of a knife-shaped structure, and the knife edge is a contour curve of the outer wall of the medicine discharge cylinder 304 after longitudinal cutting, so that deformation and expansion can be timely realized when air is charged, the liquid medicine is gradually squeezed into an affected part, the tight fit with the inner wall of the anorectum is realized, and the medicine is intensively supplied. To achieve the above effect, the present embodiment also provides another specific structure for the connection portion of the medicine discharging barrel 304 and the elastic sleeve 3: as shown in fig. 6, that is, during the manufacturing process, the drug output cartridge 304 is a cylindrical tubular structure, where the wall of the cartridge can be made thicker, the end of the tube facing the outside of the elastic sheath 3 is flared, and the side wall of the elastic sheath 3 around the flare is thinner than the other side walls, so as to form an annular deformation gasket 305, and the deformation gasket 305 expands to bulge outwards when the annular expansion cavity 4 is filled with a rated amount of air, so as to further press and contact the inner wall of the anus and intestine; when the structure is inflated with air, the elastic sleeve 3 expands and deforms, and the deformation gasket 305 is firstly contacted with the inner wall of the anorectal to lock the administration range; that is, in the state of not being inserted into the anorectal tract, after expansion, the peak of the bulged portion of the deformable washer 305 and the remaining surface of the elastic sleeve 3 around the peak have a height difference of D > 0, so that when insertion is performed, the deformable washer 305 is firstly contacted with the inner wall of the anorectal tract to lock the administration range, and is firmly fixed in the anorectal tract with the remaining surface of the elastic sleeve 3 also in close contact with the inner wall of the anorectal tract, and at the same time, the medicinal liquid is prevented from scattering to a part other than the affected part, and the administration amount is most accurate in such a structure, and the medicinal liquid is least likely to flow out to a part other than the outlet of the drug cartridge 304.

When the technical personnel in the field are making, preferably, the administration channel inlet of the rear section 2 of the administration tube is connected with the flexible infusion tube 6 for conveying the liquid medicine, the rear section 2 comprises a cylindrical section and a conical table section, the cylindrical section is coaxially connected with the conical table section, the central part of the large end of the conical table section is coaxially connected with the large end of the front section 1, the diameter of the front section 1 is smaller than that of the conical table section, and a gap is formed between the end face of one end of the elastic sleeve 3 departing from the bullet 301 and the end face of the large end of the conical table section, so that the elastic sleeve 3 is more convenient to fix and install, and particularly, the gap ensures that the elastic sleeve 3 can deform and expand freely. In addition, the outlet end of the air pipe 5 of this embodiment is communicated with the upper end of the annular expansion cavity 4 after penetrating through the side wall of the front section 1 close to the conical frustum section, so as to facilitate the connection and laying of the air pipe 5. The warhead 301 part of the elastic sleeve 3 can also be of a solid structure with the tip part rounded, the elasticity of which is weaker than that of other parts, so that the medicine feeding tube is mainly convenient to insert, and meanwhile, the elastic sleeve 3 is expanded in the circumferential direction to cling to the inner wall of the anorectum as much as possible. Furthermore, the free end of the front section 1 of the administration tube is provided with an internal expanding groove with a T-shaped cross section, a bolt-shaped T-shaped bulge 302 is axially arranged on the central inner side wall of the bullet 301 of the elastic sleeve 3 towards the internal expanding groove, and the T-shaped bulge 302 is embedded into the internal expanding groove to fill the internal expanding groove, so that the elastic sleeve 3 is well fixedly connected to the front section 1.
