TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field, concretely relates to a obstetrical adjustable length sterile sleeve. BACKGROUND

[0002] Manual placenta removal is a measure that must be taken by doctors under certain special circumstances, such as placental retention or placenta that cannot be delivered spontaneously. During this process, the doctor needs to carefully separate the placenta between the endometrium and the placenta by hand to ensure that the placenta is completely detached from the uterus. This surgical procedure requires high operating skills and strict aseptic protection for the doctor.

[0003] In clinical practice, especially when dealing with complications such as placental retention or placental adhesion, doctors may need to perform manual placenta removal. Usually, the doctor has already worn a standard glove, but the length of the upper sleeve part of the glove is difficult to adjust according to the length of the doctor's arm, often leading to the doctor's fingers, wrists, and even forearms directly contacting the blood, amniotic fluid, and other body fluids of the pregnant woman during the process of deepening into the uterus to remove the placenta.

[0004] In summary, how to solve the problem that the length of the upper sleeve part of the glove is difficult to adjust according to the length of the doctor's arm, often leading to the doctor's fingers, wrists, and even forearms directly contacting the blood, amniotic fluid, and other body fluids of the pregnant woman during the process of deepening into the uterus to remove the placenta has become a difficult problem that needs to be solved in this field, so it is necessary to propose an obstetrical adjustable length sterile sleeve. SUMMARY

[0005] To solve the above problems, the utility model provides an obstetrical adjustable length sterile sleeve, which is used to provide sterile protection for doctors that can be flexibly adjusted according to the length of the individual's arm when performing manual placenta removal. The sleeve can safely and conveniently adjust the length of the sleeve, effectively preventing the doctor's fingers, wrists, and forearms from directly contacting the blood and amniotic fluid of the pregnant woman during the operation, thereby greatly reducing the risk of cross infection.

[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows: an obstetrical adjustable length sterile sleeve, comprising a glove part; a sleeve part for wrapping the arm part is arranged at the top of the glove part, the sleeve part comprises a ring-shaped air bag, the bottom of the ring-shaped air bag is fixedly connected with the top of the glove part and is in communication; the top of the ring-shaped air bag is recessed and folded in the ring-shaped air bag; an air inlet hole is opened on the side wall of the ring-shaped air bag, the air inlet hole is detachably connected with and in communication with a positive pressure pump assembly; a length observation assembly for indicating the length of the top of the ring-shaped air bag extending out is arranged in the ring-shaped air bag.

[0007] The technical principle of the above scheme is as follows:

[0008] The utility model discloses a pump body produces positive air pressure through being integrated in the positive pressure pump assembly, and the air pressure enters the annular air bag inside through the air inlet hole, makes the top area that originally recessed and folded in the annular air bag gradually expand and stretch out, to increase the effective length of the sleeve part, the doctor can adjust the expansion degree of annular air bag through the working state of control positive pressure pump assembly according to actual needs, and then realize the flexible adjustment of sleeve length, not only ensure that the sleeve length can closely fit the arm length of different doctors, but also provide an additional protective layer, effectively block the blood and amniotic fluid of the arm of doctor that possibly contacted in the operation process.

[0009] Meanwhile, the setting of the length observation assembly enables the doctor to intuitively observe the expansion state and top stretching length of the annular air bag, so that the length of the sleeve can be more accurately controlled.

[0010] The above scheme has the following beneficial effects:

[0011] 1. In the utility model, the doctor can wear the sleeve on the hand before the operation to implement the whole operation process, when the placenta stripping operation is not needed, the doctor can use it as an ordinary glove part, when the doctor needs to perform the placenta stripping operation, only the top area originally recessed and folded in the annular air bag needs to be gradually expanded and stretched out through inflating the annular air bag, so that the effective length of the sleeve part is increased, and the doctor can adjust the stretching length of the annular air bag through the working state of the control positive pressure pump assembly according to actual needs.

[0012] 2. The sleeve of the utility model does not need to be repeatedly put on and taken off, and the length adjustment can be completed only through inflating, so that the risk of infection caused by putting on and taking off the glove is greatly reduced.

[0013] 3. When the sleeve of the utility model is stretched and contracted, the cooperation design of the annular air bag and the positive pressure pump assembly is adopted, smooth and continuous length adjustment is realized, the feeling of restraint or discomfort caused by the fixed size or inconvenient adjustment of the traditional sleeve is avoided, the operation flexibility and comfort of the doctor in the operation process are improved, and meanwhile, the design also ensures that the sleeve can closely fit the arm when the length is adjusted, effectively prevents the penetration of body fluid, and further enhances the effect of sterile protection.

[0014] Further, the length observation assembly includes a plurality of elastic sheets symmetrically and fixedly connected to the inner side wall of the annular air bag, and the elastic sheets are arranged in equidistant distribution from bottom to top in the annular air bag.

[0015] Beneficial effect: since the elastic sheets are arranged in equidistant distribution from bottom to top in the annular air bag, the setting of the elastic sheets provides an intuitive visual reference, and the doctor can identify the stretching length of the annular air bag through the elastic sheets.

[0016] Further, the telescopic control assembly comprises a sliding block fixedly connected to the inner top wall of the annular air bag; the sliding block side wall and the elastic sheet are in sliding fit.

[0038] The following detailed description illustrates the specific implementation method:

[0039] Example 1:

[0040] As attached Figures 1-4 As shown: An adjustable-length sterile sleeve for obstetric use includes a glove part 1; the top of the glove part 1 is provided with a sleeve part 2 for wrapping the arm, the sleeve part 2 includes an annular air bladder 3, the bottom of the annular air bladder 3 and the top of the glove part 1 are integrally formed and connected; the top of the annular air bladder 3 is recessed and folded inside the annular air bladder 3; an air inlet 4 is opened on the side wall of the annular air bladder 3, the air inlet 4 is detachably connected and connected to a positive pressure pump assembly; a first one-way valve 9 is connected inside the air inlet 4, the first one-way valve 9 is made of medical silicone.

[0041] The length observation assembly is arranged in the annular air bag 3 for indicating the length of the top of the annular air bag 3, and the telescopic control assembly is arranged in the annular air bag 3 for controlling the length of the top of the annular air bag 3.

[0042] The telescopic control assembly comprises a sliding block 5 which is integrally formed in the inner top wall of the annular air bag 3.

[0043] The length observation assembly comprises a plurality of elastic sheets 6 which are symmetrically and integrally formed in the inner side wall of the annular air bag 3, and the elastic sheets 6 are arranged in equal distance from bottom to top in the annular air bag 3, and the side wall of the sliding block 5 and the elastic sheets 6 are slidingly matched.

[0044] The top of the annular air bag 3 is provided with an air outlet hole 7 which is detachably connected and communicated with a negative pressure pump assembly; the air outlet hole 7 is communicated with a second one-way valve 10, and the material of the second one-way valve 10 is medical silica gel.

[0045] The glove part 1 is made of chloroprene rubber material; the outer side wall of the annular air bag 3 is fixedly bonded with a nitrile rubber layer; the annular air bag 3 and the nitrile rubber layer are transparent structures.

[0046] The specific implementation process is as follows: before the operation, the medical staff needs to carefully check the integrity of the obstetrical sterile sleeve with adjustable length, including whether the glove part 1 is damaged, whether the annular air bag 3 has air leakage phenomenon, and whether the positive pressure pump assembly, the negative pressure pump assembly, the first one-way valve 9 and the second one-way valve 10 are working normally; after confirming that the sleeve is not damaged, the sleeve is thoroughly disinfected to ensure the sterile state to meet the medical safety standards; the doctor wears the obstetrical sterile sleeve with adjustable length on the hands after washing and drying the hands, ensures that the glove part 1 tightly fits the hands, and the annular air bag 3 part of the sleeve part 2 naturally wraps the lower segment of the arm.

[0047] The positive pressure pump assembly is connected to the air inlet hole 4 of the annular air bag 3 through a special sterile pipeline, in the embodiment, the positive pressure pump assembly is a positive pressure pump, in the embodiment, the model of the positive pressure pump is preferably Oumeng 1.5E-32; and the connection is ensured to be tight and leak-free; before inflation, it is confirmed that the top of the annular air bag 3 is completely recessed and folded in the annular air bag 3, the sliding block 5 is located at the lowermost end of the elastic sheet 6, indicating that the sleeve is in the shortest state; if Figure 3As shown, the first one-way valve 9 is a one-way valve structure formed by the contact of one end of two arc-shaped valves. At this time, due to the special design of the first one-way valve 9, the elastic valve of the arc-shaped surface of the first one-way valve 9 is changed from the initial closed state to the open state by pushing the first one-way valve 9 in the air inlet hole 4 through a sterile pipeline. At this time, the medical staff can manually open the positive pressure pump assembly to fill gas into the annular air bag 3. Due to the fact that the top of the annular air bag 3 is folded in the annular air bag 3, and due to the fact that the nitrile rubber layer fixedly bonded on the outer wall of the annular air bag 3 has great elasticity, the nitrile rubber layer can tightly cover the annular air bag 3. As the gas is pumped into the annular air bag 3, the gas will push the top of the annular air bag 3 to gradually stretch out of the annular air bag 3, at which time the sleeve part 2 can be stretched. The doctor does not need to take off the sleeve part 2, but only needs to put on the sleeve part 2 to adjust the length of the sleeve part 2. At the same time that the sleeve part 2 is stretched, it is also possible to avoid frequently putting on and taking off the sleeve part 2 to adjust the length of the sleeve part 2, and at the same time that the sleeve is folded, it is also beneficial for the doctor to wear the glove part 1.

[0048] When the annular air bag 3 is stretched out, the sliding block 5 integrally formed in the top wall of the annular air bag 3 can move from the lower part to the upper part in the annular air bag 3. Since the elastic sheets 6 are equidistantly arranged from the lower part to the upper part in the annular air bag 3, the side wall of the sliding block 5 and the elastic sheets 6 are in sliding fit. When the sliding block 5 slides to the bottom of the elastic sheet 6, the elastic sheet 6 can buffer the sliding block 5 under the action of its own elasticity, thereby avoiding the fact that the top of the annular air bag 3 is completely popped out under the action of the gas pressure in the annular air bag 3. At the same time, the annular air bag 3 and the nitrile rubber layer are arranged in a transparent structure, so that the medical staff can judge the inflation state and the top stretching length of the annular air bag 3 by observing the position of the sliding block 5 moving to the corresponding elastic sheet 6 when the sliding block 5 slides between the elastic sheets 6.

[0049] When the annular air bag 3 reaches the specified stretching length, the medical staff closes the positive pressure pump and removes the sterile tube connecting the positive pressure pump and the air inlet hole 4. At this time, the first one-way valve 9 can return to the closed state under the action of the arc-shaped valve returning to the deformation, thereby avoiding the occurrence of the gas leakage phenomenon. At the same time, the doctor can connect the negative pressure pump assembly to the air outlet hole 7. In the present embodiment, the negative pressure pump assembly is a negative pressure pump, and the model of the negative pressure pump is preferably kamoer KLVP08. The negative pressure pump sucks the gas in the annular air bag 3 to the top of the annular air bag 3, so that the annular air bag 3 is contracted and the inner walls of the annular air bag 3 are tightly attached to each other, thereby reducing the diameter of the sleeve part 2. At the same time that the annular air bag 3 is contracted, the nitrile rubber layer can also tightly attach the inner walls of the annular air bag 3 to each other, thereby further reducing the diameter of the sleeve and reducing the discomfort of the sleeve part 2 to the patient. At this time, a part of the residual gas at the top of the annular air bag 3 can also expand the top of the annular air bag 3 to make the top of the annular air bag 3 tightly attached to the arm, thereby further increasing the stability of the doctor wearing the sleeve part 2.

[0050] After ensuring that the sleeve part 2 is of appropriate length and closely fits the arm, the doctor can begin the hand placenta procedure; during the operation, sterile operation must be maintained at all times to avoid cross infection; if the length of the sleeve part 2 needs to be adjusted during the operation, the doctor can repeat the above inflation step to adjust the length of the sleeve part 2, and after ensuring that there is no residual gas inside the annular air bag 3, the doctor can easily take off the sleeve part 2.

[0051] The utility model discloses, the doctor can wear on the hand and carry out the implementation of the whole operation process before the operation, when not needing to do placenta stripping, the doctor can use as ordinary glove part 1, when needing the doctor to do placenta stripping, only need to through the inflation of annular air bag 3 make the top area that originally recessed and folded in annular air bag 3 gradually inflate and stretch out, thereby increase the effective length of sleeve part 2, the doctor can according to actual needs, through the working state of control positive pressure pump to adjust the stretch-out length of annular air bag 3, simultaneously still ensured that sleeve part 2 can keep closely fitting the arm of the doctor when adjusting the length, can safely and conveniently adjust the length of sleeve part 2, effectively avoid the risk of cross infection that the doctor directly contacts the blood and amniotic fluid of parturient woman such as body fluid with finger, wrist and forearm during the operation, thereby greatly reduce.

[0052] Embodiment 2:

[0053] As shown in the accompanying drawings, Figure 1 The difference from embodiment 1 is that the finger tip positions of the glove part 1 are integrally formed with anti-skid protrusions 8.

[0054] The specific implementation process is as follows: during the operation, the doctor can use the anti-skid protrusions 8 at the finger tip positions of the glove part 1 to increase the friction of the glove on the placenta during the placenta stripping, and the anti-skid protrusions 8 at the finger tip positions can reduce the sliding of the placenta during the placenta stripping during the hand placenta operation, so that the placenta is more easily stripped during the operation, the difficulty and time of the operation are reduced, and the pain of the parturient woman is alleviated.

[0055] Obviously, the above embodiments are only examples for clearly illustrating, and not limit the embodiments. For ordinary skilled in the art, on the basis of the above description, other different forms of changes or variations can be made. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the utility model.
